SUCCESSES, EDIBLE AND OTHERWISE

October 2, 2015/8 Comments/in Design, Flowers, Gardening, Vegetables/by Lee Reich

Stand Up Straight!

I am particularly proud of my Brussels sprouts this year — and I haven’t even tasted them yet. How odd that I should be proud of this vegetable that I spurned in the past, often quoting a friend who referred to them as “little green balls of death.” Then I put my own twist on that description, saying that perhaps the friend meant that Brussels sprouts were only palatable a “little boiled to death.”
I’ve come around, and decided, a couple of years ago, that Brussels sprouts were worth growing, despite their high demands on space and time. For good production in northern climates, the seeds need to be sown indoors in early March, and then harvest doesn’t start until October or sometime after the first frost. And for all that waiting, each plant — a mere single stalk with whorls of leaves from top to bottom and a sprout at the base of each leaf — takes up an area of about three feet by three feet.

Gustas Brussels sprouts, standing up straight.

   Things would be bad enough if a Brussels sprouts plant just grew straight up to fill its allotted area. But the plant can’t support itself, so in its youth it flops down on the ground. Once that supine stem has created a firm base upon which to rise, the end of the growing stem curves more or less upward according to original plan. That youthful waywardness wastes and muddies lowermost sprouts, with the sprawling plant demanding even more space, which is a problem in an intensively-planted garden.
   This summer, before the plants even had time to consider flopping down, I poked a bamboo pole into the ground next to each one, which I tied to the pole, adding ties to keep up with growth. Perhaps a bit too orderly for a vegetable garden, but my Brussels sprouts “trees,” each now over four feet tall, look quite attractive.
   The “trees” are not likely to grow much higher because I pinched out the top bud of each plant in early September. This pinching redirects the plants energy from the highest growing point to the side shoots — which are the sprouts. All month, the sprouts have been fattening, soon to be snapped off and eaten.

Not Your Average Marigold

    I also count among this season’s successes two little-known flowers, both of which elicited “oohs and ahhs” from visitors here. One of the flowers were Signet marigolds. You might think, marigolds?, they’re okay, but more “ho hum” than “ooh and ahh.” Not so.
   Signet marigolds, Tagetes tenuifolia, are a different species from common marigolds, and they look a little different. Mostly, they’re smaller, expanding into amorphous mounds of fine, lacy, lime-green leaves, from which stare out small yellow or orange blossoms — most charming. A lemony-marigold aroma wafts from both the blossoms and the leaves.
   Actually, the aroma can waft over the whole garden if you plant enough Signet marigolds — which I did this year. In the past, the seeds never germinated very well for me, so I just spot planted what few seedlings I could raise here and there in the garden.
   This spring, in mid-April, I sowed the seeds densely in an 8 by 6 inch seed flat. The dense planting led to an excessive number of crowded seedlings. While they were still young, I gently lifted each one to transplant into its own potting-soil-filled cell to grow for a month or so before planting out in the garden.
   The few plants I poked in at the feet of vegetable beds on either side of the main path through the vegetable garden have grown into sprawling mounds that wash into the main and side paths of the vegetable garden like seawater into an undulating beach. The flowing mounds effectively soften any excessive orderliness of the garden — from the soldier-straight Brussels sprouts plants, for example.

A Cardinal in our Midst

    My grape arbor creates a horizontal roof nine feet above my terrace. Each of the four grape vines rises to that height on a single trunk. What an opportunity for a climbing vine, especially one that climbs by twining! My other floral success this year has been with such a twining plant, cardinal climber (Ipomoea x multifida, a hybrid created by mating I. coccinea and I. quamoclit).
   In the past, other species of Ipomoea climbed those trunks. Morning glory was one, but that only blooms, of course, in the morning. Moonflowers have also dressed up the trunks, but they bloom only at night.
   So this year, cardinal climber was the Impomoea species for the grape trunks. It blooms all day long, clothing itself in blossoms from top to bottom. The size and color of the blossoms, an inch or so across and cardinal red, seem best for relatively close viewing when sitting on the terrace.
   No need for these flowers to soften any excessive orderliness of the arbor. The grape trunks wend their way skyward and their long, new shoots create plenty of disarray except right after they are pruned each spring.

I WAS WRONG

September 9, 2015/0 Comments/in Design, Flowers, Fruit, Gardening, Planning, Vegetables/by Lee Reich

Hog Peanuts, Groundnuts, Whatever

I was wrong. A few weeks ago I wrongly dissed groundnut (Apios americana) for invading my flower garden. Yes, I planted it; that was 30 years ago, and it’s resisted my attempts at eradication for the past 28 years.
The worse culprit, this year at least, is related to groundnut. Like groundnut, it’s a legume, it’s native, it’s edible, and it’s a vining plant with compound leaves. But each leaf of hog peanut (Amphicarpaea bracteata), has 3 egg-shaped leaflets, as compared with groundnut’s 5 lance-shaped leaflets.

Hog peanut leaves

Hog peanuts produce flowers both above ground and below ground. Below ground is where the goodies are. Pods that form there enclose peanut-sized seeds that allegedly are tasty raw or cooked. I’ll see if I can dig some up in a few weeks. Like groundnuts, hog peanuts provided food for Native Americans; the plants were among the four sacred plants of the Osage.
So what can be bad about a plant that tolerates some shade, adds nitrogen to the soil, and yields an allegedly tasty seed below ground? The problem is that it’s run wild over the flower bed, the fine stems and leaves attempting to smother, sometimes successfully, every plant in its path. Even non-native, invasive Japanese stilt grass and garlic mustard can’t hold their own against hog peanuts.

Permaculture Reality

Low maintenance, protection and enrichment of soil, and edible parts recommend hog peanut and groundnut to permies (permaculturalists). As with so much in permaculture, these plants perform better in theory than in practice.

Hog peanut & groundnut strangling crocosmia

In humid climates, plant growth — and not just groundnut and hog peanut — can run rampant. Growth needs to be controlled and balanced, a job made more difficult in a permaculture “guild” of groups of plants working together. I’m all for interplanting different species to make best use of light, water, and soil resources, and form communities that resist pests — to a point.
   I’ve had the opportunity, over the years, to visit the permaculture garden planted by students at the University of Massachusetts in Amherst. Now in its 5th year, the garden pays tribute to the compost, mulch, and sweat students put into soil preparation. The plants have grown very well. Too well, perhaps. One could say that the plants have commingled nicely; from another perspective, one could say that they are overunning each other. A blackcurrant bush or bushes has swelled into a mass of unapproachable stems 10 feet deep and wide. Chives and oregano have each taken over their areas. (How much chives or oregano can you eat? I’d rather eat tomatoes.)
   Not that I’m immune to such errors. A few years ago I created a very permaculturesque planting that included elderberries, seaberries, and rugose roses almost elbow to elbow. It all looks very nice but these three shrubs all spread by suckers. I keep everything in check with elbow grease and a scythe . . . for now, but Mother Nature is relentless. Am I?
   The most productive and accessible parts of the UMass garden are the beds of kale, beets, and other vegetables — straight rows in cultivated soil. How un-permaculturalesque.
   Oh, I forgot to mention the groundnuts at UMass. Stems of those plants are twining around and overpowering others in their guild in an ever-widening circle. Even if the groundnuts could peacefully coexist with their neighbors, grubbing up the golf ball size tubers will require an inordinate amount of time and soil discombobulation.
   My memory fails me. Perhaps it was hog peanut rather than groundnut vines threatening their neighbors. Perhaps it was both plants. Hog peanut has been suggested for erosion control, and as a groundcover, a livestock forage, and a food for humans. My suggestion: Hog food. Turn some hogs loose in a patch, and they’ll fatten as they clear the ground of this pernicious weed. Does anybody have a small hog for rent?

Elderberry Wine — No, Syrup

    Elderberry looked to be one of the most successful plants in the UMass permaculture garden. It grows fast and it grows high. My two plants, now in their third year, yielded more than four gallons of berries. And harvest, last week, was quick and easy; aggressively tickling the umbels had the berries quickly filling a basket.
   Elderberries can also be recommended for their flowers and the berries’ deep, blue color. Flowers open in June to dinnerplate size umbels of small, white blossoms. They’re good for tea, fritters, or to flavor wine.
   The berries impart their good color, but little flavor, to wine, pie, and juice. (They should not be eaten uncooked or unripe.) There’s a bit of scientific evidence than an extract or syrup of the berries can help fight flu, perhaps other ailments also. I’m good at growing fruit, not cooking it, so I gave my crop to Dina Falconi who concocted a syrup using the recipe from her book Foraging & Feasting. I look forward to tasting the benefits of my horticultural and her culinary skills.

MAYPOP & ASPARAGUS, BEAUTIFUL & EDIBLE

August 28, 2015/17 Comments/in Design, Flowers, Fruit, Gardening/by Lee Reich

Awesome, Made More So

You would think — or I, at least, would think — that a purple and white passionflower would be more passion-inducing than one that was merely white. Not so. The white one displays a passionate juxtaposition between a pure, lily-whiteness and a wildness from the the squiggly, threadlxike rays of its corona backdropping female stigmas’ that arch over the yellow pollen-dusted anthers.
   A white passionflower is a rarity. Mine sprung up by chance from a batch of seeds I planted last year. Mostly the plants bear purple and white flowers.
   Most passionflowers are tropical, but this white-flowered passionflower, like its mother and siblings can survive outdoors even with our winter lows of well below zero degrees Fahrenheit. Commonly known as maypop, Passiflora incarnata is native to eastern U.S. as far north as Pennsylvania. Tropical passionflowers, are woody perennial vines; maypop is an herbaceous perennial vine, dying back to the ground each fall, but sprouting each spring from its perennial roots.
   Vine growth begins late, typically not showing until early June here in the Hudson Valley. Summer warmth coaxes it along to begin flowering in July. Once the flowers appear, they continue almost nonstop through the summer until fall, with one to a few new flowers opening each day.
   Fruits soon follow the flowers. Yes: Fruits! Passionfruits are delicious, and maypop fruits taste pretty much the same as tropical passionfruits — the main flavor in Hawaiian punch, in case you think you’re unfamiliar with the fruit. The fruit is egg-shaped, its interior packed full of seeds, each of which is surrounded by a thick coat of deliciousness, in much the same way as pomegranate seeds.
   I haven’t figured out where to plant my maypops, so they’re still in large pots. Years ago, I had a couple in the ground at the base of a lilac tree. The maypops climbed into the lilac to put on a show through summer, after the lilac itself was no longer interesting. Now I want a fence for it to clothe in a heat-capturing spot in full sunlight. Maypop does spread underground, to the extent that it’s considered a weed in the Deep South, where it really can run wild. Spread is less here, but still, I need a location for it that takes that potential into account. Alternatively, I’ll plant it in a deep, bottomless container, such as a chimney flue.

The Other Kind of Passion

    If truth be told, the “passion” that gave passionflowers their name refers to a religious passion, the passion of Christ. The plant was a seventeenth-century teaching tool for spreading the gospel.
   Passionflower “had clearly been designed by the Great Creator that it might, in due time, assist in the conversion of the heathen among which it grows,” wrote a Christian scholar of the seventeenth century. The ten so-called petals (botanically, five petals and five petal-like sepals) were taken to represent the ten apostles present at the crucifixion. The threadlike rays of the corona were taken for symbols of the crown of thorns. The five stamens and three styles referred, respectively, to the five wounds of Christ and the three nails used in the crucifixion. Even the rest of the plant figures in, with the three-lobed leaves representing the Trinity and the tendrils representing the scourges.
   Passionflowers are heavenly enough to bring on a religious devotion to growing the plants. Which brings us to sex . . . The flowers are andromonoecious, which means that on every plant some flowers are perfect (have functioning male and female flower parts) and some are functionally male. Functional males have female parts but are functionally male either because their stigmas are held upwards out of the way of insect visitors or because their female parts are atrophied. So grow two plants if insects are to do your bidding, one plant if you’ll take care of pollination.
   See my book Uncommon Fruits for Every Garden for more — a whole chapter! — on hardy passionfruits.

“Sparrowgrass” Need Help

    My asparagus is now a six-foot-high, ferny hedge outside and along the eastern edge of one of the vegetable gardens. It’s a pretty sight until my eyes drop downward to see the weeds sprouting at the “hedge’s” feet. Not that the weeds are putting the brakes on the asparagus, but they are making seeds that then spread into the vegetable garden.
   I’ve seen gardens and farms where asparagus beds were abandoned because of weeds. Mulching and early season weeding only go so far.
   The usual recommendation for growing asparagus is to purchase roots and plant them at the bottom of a deep trench. As new shoots grow, the trench is gradually filled in with soil.
   More recent research showed that such heroic efforts were unnecessary. I planted my asparagus just deep enough to get them into the ground.
   The reason for trenching asparagus was to get the crowns low enough so that a tiller or hoe could be used to kill weeds without damaging the crown. All of which is impossible when the crowns are planted with their buds just beneath the surface.
   So these days I’m periodically crawling into the hedge, becoming very intimate with the ground there, and pulling out all the weeds.

UNTRADITIONAL ROSES AND HOEING

July 9, 2015/5 Comments/in Flowers, Gardening, Pests, Soil, Tools/by Lee Reich

Rose Fan: No, Yes?

I’ve said it before and I’ll say it again: I’m not a big fan of roses. But I can’t help myself. The garden is awash in golden yellow, crimson red, soft pink, apricot pink, and plain old pink blossoms. Almost all of this is thanks to David Austin, breeder of roses.
My father was a big fan of roses, so I was exposed to them at an early age. Pre-dating Mr. Austin’s creations, my father’s roses were the ever popular — except with me — hybrid tea roses which everyone — except me — liked and likes for their pointy, formal blossoms, their bold colors, and their repeat bloom. Nobody mentions their gawky stature, general lack of strong or interesting fragrance, and attraction to pests.

L. D. Braithewaite rose, cold-hardy and just keeps blooming

   David Austin roses won me over with their softer colors, fuller blossoms borne on more full-bodied bushes, delicious fragrance, disease resistance, and repeat bloom. Not all have all of these qualities, of course.
   L. D. Braithewaite has been the most florific of my David Austin roses, even weathering two very cold winters unscathed. The crimson, red petals made their first appearance a few weeks ago, and are still going strong. They’re not my favorite color, though. Least successful of my roses has been Bibi Mazoon, which is my favorite of the David Austin roses, in its blossoms, at least. Cup-shaped and apricot pink, the blossoms are admittedly few and far between, and can hardly be held up by the weak stalks. The rich yellow color of Golden Celebration is another of my favorites; this variety blooms fairly well and also pulled through winter unscathed.
   I grow a few pink David Austin roses, including Charlotte, Brother Cadfael, Sharifa Asma, and they’re all looking pretty and growing well.
   Of all the roses I grow, my favorite is . . . well, I’m not one hundred percent sure of its name. It started life here many years ago as a cutting of Rose de Rescht, given to me by local herbalist Anne Solomon. Except that, reading descriptions of Rose de Rescht, I came to realize that mine wasn’t it. Whatever the name (after all, “a rose is a rose is a rose . . .”), the attractive crumpled, crêpe-paper blossoms fill the air with a delectable, heady fragrance, more than that of any of the roses I grow. The bush, robust, armed with prickles and clothed in leaves having having a bluish cast, has never been fazed by pests or cold.
   With the help of some rosarians (especially those at www.heirloomroses.com), Rose de Rescht was assigned its probable proper name: Ispahan. The alluring name, the blossoms, and the toughness of the plant more than offset the plant’s one deficiency, that of blossoming only in spring.

Hoe, Hoe, Hoe, But It’s Not Xmas

I can’t just stop and smell the roses all day long; there’s work to be done. Time to grab a hoe and hoe, hoe, hoe. How retro, you may think. What with all sorts of mulches and tillers and tilthers available, the hoe is an under appreciated and underused garden tool these days.

My favorite hoes: wire weeder and winged weeder

But a hoe does good work — if you use the right hoe in the right manner. The best hoes, which include the scuffle hoe, the stirrup hoe, and the colinear hoe, have sharp blades that, in use, run parallel to the surface of the ground. Among these types of hoes, my personal preference has always been for the winged weeder, which looks like an airplane wing, sharpened fore and aft, attached at an angle to a long handle.
   I’ve recently taken up with another hoe, the wire weeder (from http://twobadcatsllc.com), whose head is a stiff wire cleverly bent to be easily worked amongst plants. Rotated 90 degrees puts its short edge to work, which is very useful for wending the head in amongst closely spaced plants. The lightweight aluminum handle doesn’t look traditional but makes the tool very light and spry in use.
   Ideally, I’m out in the garden with my winged weeder or wire hoe on sunny mornings following rains. (I’m not sure which hoe I like better, so I alternate between them.) The goal is to loosen the soil, uprooting weed seedlings before they establish, and leaving a rough surface to welcome in the next bit of rain. The work, if it could be called that, is quick and easy if done before weeds grow large.
   Only when weeds get out of hand is it necessary to get out the tool that most people associate with the word “hoe,” the traditional garden hoe with the large blade at 90 degrees to the handle. This hoe is also the one Charles Dudley Warner was referencing when he stated (My Summer in a Garden, 1870), “what a [gardener] needs is a cast-iron back, with a hinge in it.” I reserve mine for mixing concrete.

Hoe or Mulch

Not that mulching doesn’t also have its place in the battle with weeds`. Mostly, though, you have to do one or the other — mulching or hoeing — thoroughly. It’s impossible to hoe even thinly mulched ground.

Vegetable garden, kept “weed-free” and fed by compost mulch

Unless, that is, the mulch is compost. Given that mulch is anything that covers the ground, compost qualifies as mulch, except that you can plant right in, or hoe, a compost mulch just as if it was soil.
Weeds occasionally poke up through or sprout within the inch of compost with which I blanket my vegetable garden beds each year. I pull large weeds individually. Periodically, or where small weeds are starting to show, I’m out in the garden, sliding the business end of either my winged weeder or wire hoe back and forth, or just pulling it along, just beneath the surface of the ground.

DRIP, DRIP, DRIP, WHERE’S THE AGUA?

June 12, 2015/8 Comments/in Flowers, Fruit, Gardening, Houseplants, Soil, Vegetables/by Lee Reich

I’m Dripping, So Why Am I Watering?

Up to a couple of weeks ago, little water had dropped from the sky this spring here in the Hudson Valley. But a drip irrigation system automatically waters many of my plants. So why have I been spending so much time with hose in hand?
   Not all my plants drink in the drips. Trees and shrubs are on their own except their first year in the ground when I religiously hand water them every few days initially, and then once a week throughout the season. These plants get 3/4 gallon per week for every square foot spread (estimated) of their root systems. That’s equivalent to an inch of rainfall which, if it does fall, exempts me from a few days of watering.
   A couple of inches depth of hay, leaf, or wood chip mulch around the trees and shrubs seals in moisture to make best use of my efforts. Also, I start with smaller plants — less than 4 feet tall — which become independent of my watering sooner because a larger proportion of their roots are soon foraging around in surrounding soil that those of larger plants.
   My flower beds also don’t get dripped. Although the soil surface is dry, moisture carried over from winter still sits in lower depths, into which established perennial flowers’ roots can tap. Annuals and newly planted perennials need to be watered on the same schedule as young trees until their roots reach that moisture.

My blueberries are my only dripped shrubs

It is my garden vegetables that drink in the benefits of my drip system. But even here some hand watering is needed these days. Down each bed runs 1 or 2 drip lines, with emitters along the lines spaced 6 inches apart. As water enters the soil, capillary pull from small spaces between the soil particles draws water sideways and, along with gravity, downward. The resulting wetting fronts have the shape, if you could look at a cross-section of the soil, of an ice cream cone. In clay soils, with small particles and, hence, a lot of capillary draw, that ice cream cone is very fat; in sandy soils, it’s narrow, a couple of feet wide at its broadest as compared with the 6 foot spread in a clay soil.
The wetting fronts start their sideways spread below the soil surface, deeper in sandy soils, more shallow in clay soils. In either case, the soil surface remains dry except right at the point of drip. So any vegetable transplants or seeds I set in the ground need to be hand watered until their roots reach the wetting front — except for seeds or transplants set right under or along the drip line.

Drip Irrigation Workshop June 20th; see “Workshops“, at this site, for more information.

A Statue of David

    My friend David was wondering why the leaves of his Romaine lettuce plants flopped down. I gave my usual response to most gardening questions: “Too little water.” (My other usual response is “Too much water,” often following my first response if the questioner tells of watering all the time.)
   So I asked David how much he watered, and he said he thoroughly soaked the ground by spraying it with water. Busted! It really was a water problem, too little in this case.
   In fact, thoroughly wetting the soil with the usual 4-foot-diameter, hand held spray is almost impossible. “Thoroughly wet” means soaking the ground to at least a 6-inch depth. For his hand held sprayer to do that, David would have to stand in place like a statue, sprayer in hand, unmoving, for about an hour to wet one 4-foot-diameter part of the garden before moving on to the next 4-foot-diameter area.
   When I’m watering plants in the ground by hand, I’m wetting only the small area beneath an individual plant, just enough to soak its roots as they establish themselves in the surrounding soil.

Probe the Soil

People find it hard to believe that that statuesque watering posture is really necessary. All you have to do is scratch the soil surface after a David-esque spraying of plants to see how deeply the water percolated, and you’d find only a thin layer of wet soil, at the surface.

Digital moisture probe.

Digging a hole in the ground is a good way to tell if watering was sufficient. But it’s also inconvenient.
For just a few dollars, I invested, years ago, in an electronic gizmo that bypasses all that hole digging. This soil moisture sensor has a metal probe that you plunge into the soil. Atop the probe is a dial or digital readout that tells whether the soil is “DRY,” “WET,” or something in between. More accurate sensors cost over a hundred dollars, but the cheap ones are fairly accurate and work well if coupled with observation.

Good for Pot(s) Also

The soil moisture meter is especially useful with potted plants, which might need watering every day when the weather is warm, sunny, and breezy. (With experience, lifting a pot to feel its weight is also a good measure of moisture level, as is just getting to know your plants better.)
I’m still hand watering the pots because I haven’t yet connected the drip tubes that will direct water to each of the pots.

MONOCOT THREATENED, MONOCOT SUCCESS

June 5, 2015/8 Comments/in Flowers, Gardening, Pests/by Lee Reich

DRIP, DRIP . . . A WORKSHOP

Drip irrigation has many benefits: saves water, healthier plants, easily automated, less weeds. I’ll be holding a DRIP IRRIGATION WORKSHOP on June 20, 2015 in Bloomington, NY. Learn why drip is the better way to water and the components and designing of a drip system. And then, hands-on, we’ll design an install a system in an existing vegetable and flower garden. For registration and information, go to www.leereich.com/workshops.

Lily Turds

The turds on my crown imperial plants were unwelcome, but no surprise. I’d been forewarned that the red lily beetle (Lilioceris lilii) was in the area. Finally, it found my garden and my crown imperials.
For a relatively mobile insect, the beetle was surprisingly slow in its arrival. This native of Europe made its North American debut in Montreal in 1945 and its entrance stateside, in 1992, in Massachusetts. Since then, it has spread. Gardeners are on alert for the beetle as far away as the Pacific northwest since its sighting near Seattle in 2012.

Red lily beetle on crown imperial.

   Those turds I saw actually are turds, the beetle larvae’s excrement, piled on their backs as they feed. Perhaps the greenish brown slime that hides the red larvae will not make the larvae unappetizing to my ducks or chicken. Those larvae are hatchlings from eggs adult beetles laid a few weeks ago. After a few weeks of feeding, the larvae will pupate. New emerging adults will feed until making their way to their winter homes in fall. The worst culprits, in terms of plant damage, are the larvae.
   There are many ways to skin a cat, and many ways to deal with red lily beetles, none of which need involve highly toxic pesticides. Easiest, of course, would be to avoid growing susceptible plants. Mostly, the beetles fare are lilies (Lilium spp., which does not include daylilies) and Fritillaria species, which includes crown imperials. Susceptibility varies among lily species, with Asiatic hybrids the most vulnerable and some Oriental hybrids more resistant. Lilium henryi ‘Madame Butterfly’, Lilium speciosum ‘Uchida’, and Lilium ‘Black Beauty’ are among the most resistant.
   Because I’m already growing lilies and fritillarias, I might opt for the wait and see approach, hoping for the chickens or ducks to take care of the problem. Or take the mano a mano approach, regularly inspecting plants to pick off eggs, larvae (yuck), or adults by mano. A container of soapy water held under a leaf is useful for handpicking adults because they drop soil-ward when disturbed — also emitting a defensive chirp or squeal.
   Neem is a relatively nontoxic (to humans) pesticide and deterrent extracted from, you guessed it, the neem tree, in India. It’s effective if sprayed on very young larvae. I have too many crown imperial plants scatted about to easily spray.
   Best of all would be to find some natural controls, and they have been found. Three species of parasitoid wasps (Lemophagus errabundus, Diaparsis jucunda, and, especially, Tetrastichus setifer) have proven effective. Releases have been made in New Hampshire, Rhode Island, Maine, and Connecticut. Come on, New York, let’s get some parasitoids.

What Beautiful Onions, Thank You

Moving on to another monocotyledenous plant, this one with no pest to speak of: ornamental onions, which also go by their botanical name, alliums.
(“Monocotyledonous,” what a mouthful! This refers to the plants leaves, or cotyledons, which function either as seed leaves or as storage structures. Monocots are one broad group of flowering plants; dicots, with two seed leaves, are the other broad group).

Alliums starting to open

Last fall I reported on my planting of Allium giganteum ‘Ambassador’, which makes volleyball-sized heads of purplish blue flowers, and A. hollandicum (or A. aflatuensis) ‘Purple Sensation’, bearing similar flowers in tennis ball- sized heads. Both are nice plants for flower beds, but, as I reported, I wanted to see if they would naturalize in my south meadow.
   Early on, this spring, the experiment seemed a success. The broad, green, strappy onion leaves unfolded, drinking in sunlight, before the surrounding grasses and other meadow plants had hardly budged. As warmer weather moved in, surrounding vegetation grew more boldly, soon beginning to get the upper hand on the onions.
   Then the onions, the smaller ‘Purple Sensations’ onions, began to bloom. The blue heads were lost, at first, in the sea of dandelions, orchard grass, goldenrod, and other plants coming on strongly. But ‘Purple Sensation’ heads evidently weren’t yet at their peak. They came increasingly into focus as the heads continued spreading their starbursts of blue blossoms. ‘Ambassador’, as I write, has still to show its heads.
   Flowers are pre-packaged within fall-planted bulbs. The true test will be whether or not the alliums bloom as strongly, or at all, next spring. Perhaps the ‘Ambassador’ bulbs will even multiply, as they have in the less competitive terrain of the flower garden.

Alliums in the garden.

FEAST OR FAMINE

May 8, 2015/4 Comments/in Flowers, Gardening, Pests/by Lee Reich

Is Gardening Too Easy?

    Control yourself, Lee! Growing seedlings this time of year is too easy. Within a single packet of seeds is the potential for a gardenful of vegetable or flower plants, even shrubs and trees. As such, a packet of seeds is relatively inexpensive.
   I have envisioned delphinium in my garden, its tall, blue studded spires backed by the fence surrounding my blueberry planting. I could have just gone out and purchased a few potted delphinium plants, but I wanted a bolder effect so purchased instead a packet of seeds. Who would have thought that germination would be so good. After all, the seed germinates best when fresh and likes some cool temperatures to awaken; some people freeze the seeds in ice cubes for awhile before sowing them. I used nothing but patience, and not that much was needed.
   I couldn’t bear to discard most of the seedling, so “pricked out” 24 of them into cells of my APS seedling flat.

Seedling plants (and Sammy the dog) in spring

The same thing happened with red lupines, chocolate daisies, Yellow Gem marigolds, and . . . Growing transplants is the easy part. The difficulty will be in about a month when I’m wandering around the garden, seedling flat in one hand, trowel in the other, wondering where to plant all these flowers. (This problem does not arise with growing vegetable transplants because I keep harvest records for vegetables that let me know how many plants I need of each. Could my eyes get too full or too fat on too many flowers? No.)

Damn-ping Off, No More

    Raising transplants wasn’t always so easy for me. Decades ago, as a graduate student, I lived in a converted motel room which also became home to seedlings for my first garden. The shelves were lined with peat pots of sprouting chamomile (very easy), lettuce, beans, and other plants.
   Thence was my abrupt introduction to “damping off,” a disease that attacks seeds and newly emerged seedlings. Imagine the disappointment of a beginning gardener (me) watching seedling stems pinch in at he soil line and topple over — the telltale symptom of damping off disease.
   I soon learned that damping off was not uncommon, even among experienced gardeners. The disease is caused by any one of a few soil dwelling fungi that raise their ugly head (figuratively) given the right conditions (for them). One obvious way to try to avoid the problem is to sterilize the potting media.
   Most commercial potting mixes are sterile, as were the peat pots I was using. The problem is that the culpable microbes are everywhere, just waiting to attack when conditions are just right, conditions that I unknowingly provided for them in my motel room. The peat pots were excessively moist; the air stood still; and little light entered the room — perfect for damping off development.
   Nowadays, my seedlings rarely experience damping off. The plants get off to a good start at temperatures they enjoy, bathe in light in my greenhouse or sunny windows (or, in the past, cozied up very close to fluorescent bulbs), and a fan keeps the air moving. I also add sufficient perlite to my potting mixes so that excess water drains feely down and out of the mix.
   Years ago, soothing brews of chamomile tea would also come to the rescue — for the seedlings, not for me. That tea hasn’t been needed for a long time. I also don’t pasteurize or sterilize my potting mixes. Beneficial microbes, from the compost in my mix, and good growing conditions have thankfully made damping off nothing more than a distant memory for me.

Oh Deer!

Bigger creatures are still an ever present nightmare. Especially deer and especially after this winter. They have sheared the greenery from nearly every evergreen they could reach here, the hollies, arborvitaes (white cedar), yews, hemlock, and junipers (red cedar).

Deer damaged arborvitae and balsam fir.

   Interesting about the yews, because the foliage is toxic to many ruminants; a mouthful will kill a horse or cow within 5 minutes. Deer, according to most reliable sources, can feed on yew without ill effect. With that said, this past winter, I did find a deer dead on the ground near my yew bushes, which had been nibbled free of their foliage.
   How about the plants; how will they fare, bare. Yew tolerates all sorts of abuse in the form of pruning. Soon, new needles will start appearing along their stems. Or, if the stems are cut back, new needled shoots will soon appear. My other evergreens should also fare well. Rhododendrons and mountain laurels, which the deer left alone, also generally sprout new growth when nibbled. So any of these so-called random-branching conifers or broad-leaved evergreens can be pruned to look prettier after deer have ravaged them.
   Not so with so-called whorled branching conifers, such as pines, spruces, and firs. They generally do not resprout from bare wood, so there’s not much that can be done to prettify them now. Just lop back bare branches because they’re always going to be just that: bare.

ELUSIVE AZURE AND FRUIT

Too Hot Here For These Gems, But Maybe I Can Trick Them

   It was decades ago that Norman — gardener, orchid expert, one-time cattle farmer, and lawyer — described to me his first sighting of blue poppy, Meconopsis betonicifolia. He was traveling in England, and at this particular garden was a pond whose far side was electrified by the sky blue petals of blue poppy, perhaps the purest blue of any flower. The mirrored surface of the water stepped up the voltage, as do the frilly clusters of golden anthers trembling in the center whorls of petals.
   Since then, I’ve lusted for blue poppies but have yet to see the plant in bloom. Twice I tried to grow it, from seed. Each time the seedlings germinated and got off to a good start. Each time, in July, as temperatures here started to get steamy, the plants collapsed, dead. Blue poppy is native above 10,000 feet in the Himalayas and doesn’t like hot weather.
   I don’t feel compelled to grow the plant (although that would be nice); I just want to feast my eyes on those bluest of blue petals. To see the plant in bloom requires being somewhere: 1) in late spring or early summer, 2) with cool summers, 3) where blue poppy grows wild or has been planted. The second condition, cool summers, is found in North America in the Pacific Northwest, New England and adjacent parts of Canada, and Alaska. I like hot summers so I’m not relocating to any of these places in order to grow this plant. Also, my garden is particularly needy and entrancing in late spring and early summer, so I’m not leaving then.

I Almost Cross Paths With Blue Poppy, After 20+ Years

    As it turned out, I just missed an opportunity to see blue poppy in bloom at Longwood Gardens in Kennet Square, Pennsylvania. Not only is Longwood not far from here, but I happened to be in nearby Philadelphia two weeks ago, when the plant was in bloom. Who would have thought blue poppy could be grown in Pennsylvania?
   I had, at least, to find out how the plants are grown there. As described by Longwood horticulturalist Jim Harbage, each October Longwood has potted plants shipped from a nursery in Alaska. The plants are put into cold storage until early January, then brought into Longwood’s cool (50-60°F) conservatory to slowly awaken and, finally, blossom in March. After bloom, the plants, although perennials, are discarded.
   Most important is to keep temperatures below 70° F. Research at Longwood Gardens showed that respiration outpaces photosynthesis at warmer temperatures. The plant, essentially, starves. Warmer temperatures also cause some purpling of the petals, ruining the whole reason for growing the plant.
   Could Longwood’s prescription be mimicked in my greenhouse? Probably not. Longwood’s large, high-ceilinged conservatory, with dappled shade from tree ferns and citrus trees, perhaps also cooling mists of water puffed into the air as needed, is a lot cooler than my greenhouse. Here, greenhouse temperatures on sunny days in February and March soar, despite vent fans, into the 80s.
   How about a sunny window sill? Temperatures are cool in my house, more so the further you go from the woodstove. So that’s a possibility. But purchasing new plants every year could get expensive, especially plants that are good only for compost once their blossoms fade.
   How about starting the seeds in early or mid winter for planting outdoors to blossom before temperatures get too hot? Or starting the seeds in fall and exposing the young seedings to very cool temperatures for more assured earlier blossoms outdoors? Blue poppy, if it behaves like many other perennials, should blossom the first season if started very early or if tricked into thinking it’s been through winter before blossoming. I later learned that Chanticleer Garden, also in the Philadelphia region, gets outdoor blossoms from plants purchased in October, wintered in cold frames, then planted outdoors in March. Bloom is in April; composting is in June.
   The most important and most reliable route for me to eye blue poppy in bloom is to pencil in a trip to Longwood Gardens for early March next year.

King Red, For Fruit & Beauty, Also Elusive . . . Do Far

My blue poppy experience is reminiscent of my experience with another plant of western Asia, a plant variously called King Red Russian olive, iğde (in Turkey), botanically Elaeagnus angustifolia var. orientalis, or, erroneously, Trebizond date (which is a persimmon species).

King Red seeds, sprouting last spring

   King Red is invasive out West but definitely is not invasive here. As with blue poppy, I’ve grown the plant from seed only to have it collapse, dead, when steamy weather arrived.
   Beautiful blossoms are not the attraction of King Red, although they do sweetly perfume the air in spring. Rather, it’s the bright red fruit that is highlighted by the gray-green foliage and, when dried, is like sweet talcum powder contained within a cherry-sized, brittle shell. Even without the flowers or fruit, the tree imparts a soft, Mediterranean look to the landscape, much like an olive tree, a relative.
   I started some seedlings of King Red Russian olive last year, hoping for some genetic variability in heat tolerance. All the seedlings thrived, probably because of last summer’s relatively cool temperatures.

King Red branch that someone sent me

The seedlings are now dormant in 4 inch pots in my basement. I want 20 foot tall King Red trees so eventually the baby trees need to be planted out. I’m scoping out suitable locations with cooler microclimates. A spot receiving only morning sun is the current best candidate.
Perhaps in a few years I’ll be eating home-grown iğde while enjoying the sight of blue poppies.

LUSTING FOR AVOCADOS, HOME GROWN, OF COURSE

February 6, 2015/4 Comments/in Flowers, Fruit, Gardening, Houseplants/by Lee Reich

A Long Journey to Avocado-dom

This far north, an avocado plant provides reliable entertainment and, less reliably, the makings of guacamole. The entertainment doesn’t compare with the excitement of a car chase on the silver screen; it’s slower but very engaging.

To whit: I’ve been watching roots on two avocado pits elongate and branch. I spend a lot of time with plants; here is my opportunity to spend quality time with their roots. That’s all possible because avocado pits, suspended in water, will sprout roots whose growth can be watched. (Odd, since wet soils are the nemesis of avocado trees planted outdoors in tropical and subtropical climates, and you can’t get much wetter than water.)

Despite being plants of warm climates, avocados are frequently raised by us northerners, as houseplants. I could have planted the pits in potting soil in a pot, but would have missed out on root entertainment. So I stuck three toothpicks into and spaced evenly around each pit so that the pits could be suspended in a beaker with their bottoms — their fatter ends — sitting in water. Taking a thin slice off the top and bottom of the seed, which I did, reputedly speeds germination.

Roots typically sprout before the tops show any sign of growth.

Whoops, Things Don’t Look So Good

Avocado houseplants are so common that probably none of the above is new information to most readers. I’m embarrassed, then, to admit that my two plants have faltered in their growth.

One of them sent a sprout upwards after its roots were a couple of inches long. That sprout has dried out and, of course, ceased growth.

I noticed a slime surrounding the root of the other pit. This pit was very slow to sprout, and my guess is that there’s some bacteria attacking the weak growth.

I ascribe both failures to growing conditions which, here, indoors, are a far cry from the mostly warm, humid climes avocados call home. Mine sit near a window, experiencing wide swings in temperature in a room heated with a wood stove. Starting new plants in spring should bring better luck.

Entertained by Apical Dominance

I did get to effect and observe apical dominance on one of the plants. More benign than it sounds, apical dominance is the tendency for most vigorous growth from a plant’s uppermost buds, those either at the ends of branches or spatially at the highest points.

That vigor comes from suppression of buds lower down by auxin, a plant hormone that is produced in the uppermost buds and transported down the stem. Lopping off the top of a stem stops hormone production (temporarily, until the new higher buds start making it) so lower buds grow as they let go of their inhibitions.

The taproot growing from one of the avocado pits was threatening to bump into the bottom of the beaker so I pinched off a half inch of its tip. The effect was a mirror image to what happens with branches: within a few days, branch roots began to develop. Very entertaining.

An avocado sprout typically shows strong apical dominance, developing into a gawky plant with a single, upright shoot. Cutting the growing top back by a few inches induces branching and makes for a prettier plant.

Flowers, But No Fruit

More than beauty, I’d like fruit from my avocado plant. Under good conditions, such as in the ground in Florida, a pit would need 8 years or more before it became old enough to bear fruit. And then, said fruit might not be of best quality because the seedling would reflect whatever jumbling around of chromosomes occurred when the female flower that gave rise to the fruit that begot the seed got dusted with pollen from a male flower.

For quicker bearing and more reliable good taste, cloning is needed, in this case grafting a branch from a tree known to bear good-tasting fruits onto the young seedling. Bearing, then, occurs within 3 or 4 years, and the fruit should be identical to the mother plant from which the stem for grafting was taken.

Not so fast, though. You need two varieties for cross-pollination, and avocado has some pollination quirks. Still, my plan is to get new pits sprouting, and once their stems are large enough to graft, to get scions for grafting. Years ago, I did all this and got flowers but no fruit. I’m hopeful, this time around, to be making guacamole within 6 years.

Outside Now, For More Apical Dominance

The time is drawing near for some real gardening, which could start with pruning. I’ll be putting apical dominance to work on some young fruit trees — each a mere “whip,” single, vertical stem — planted last year. Shortening the main stem will induce side branches that will eventually become the permanent scaffold limbs of these plants. The more severely any stem is shortened, the fewer and the more enthusiastic the sprouts from the buds lower down.

NICE HIPS, BUT WHOSE?

December 26, 2014/4 Comments/in Flowers, Fruit, Gardening/by Lee Reich

2 Contenders for Hips and Rabbi Samuel Redux

As I walked along the beach, I took a look and my first thought was “Nice hips.” But what about the flowers? I’d have to return to the plant next summer to find out, a problem since I was 4 hours from home visiting a relative in Rhode Island.

Most of the roses you see growing seaside are Rosa rugosa. Common names for this plant are Japanese rose, indicating its origin, saltspray rose, indicating its tolerance to beach sand, and rugose rose. “Rugose” means “wrinkled,” which is what leaves of R. rugosa are.

The particular planting of nice-hipped roses staring back at me did not have rugose leaves. What’s more, the hips were about 3/4 of an inch across and bright red. Hips of rugose rose are usually an inch or more across and orangish-red. With this slightly different morphology and the fact that rugose rose is listed as an invasive plant, I assumed that the nice-hipped roses, recently installed as landscape plants, were another species.

Those are Rosa rugosa hips on the left, Rosa canine(?) hips on the right

With such nice hips, the plants could possibly be dog rose, R. canina, the other rose species valued for its hips. The lack of sepals on the hips also pointed the finger at dog rose. (Rugose rose hips have persistent sepals.) A even closer look would have nailed it; rugose rose’s stems have numerous prickles throughout their length while bold, large, wide, downward-facing thorns line dog rose stems. But I didn’t look closer.

Dog rose, although much less frequently seen, is also considered invasive in some places.

Sowing Seeds for More Hips (and Flowers)

As potentially invasive plants, rugose rose or dog rose should be easy to grow from seed. But no. I’ve propagated roses from seed, and it’s a slow process.

Last summer’s Rosa rugosa blossoms

Rose seeds, like those of most other fall-ripening seeds of temperate zone plants, have a physiological dormancy that prevents their immediate sprouting, the consequence of which would be death from cold. So they just sit in moist earth until they have experienced a number of hours of chilly temperatures — 30 to 45° F is ideal — before sprouting, at which time winter has presumably given way to spring weather. Instead of moist earth, that chilly habitat could be within the refrigerator in a plastic bag filled with peat moss and perlite.

But rose seeds have another impediment to germination: a tough seed coat. Plant the seed outdoors and shoots might not poke through the surface of the ground for 2 years. The first winter and summer are spent softening the seed coat, making it permeable to moisture. Beginning the second fall, chilling hours begin to accumulate so that by the second spring, the seed can awaken and grow.

I did pluck a few fruits from that Rhode Island, nice-hipped rose bush, and plan to make new bushes. But I’m too impatient to wait 2 years. “Scarifying” the seeds is a quick way to make the seed coats more permeable. Nicking them with a wire cutter does the trick but would be difficult with such small seeds. An hour or so in warm, concentrated sulfuric acid — followed by a thorough rinsing in water — is likewise effective but a bit dangerous. I’ll follow Mother Nature’s lead and soften the seed coats by keeping the seeds warm and moist. No matter how the seed coat is softened, subsequent cool, moist conditions are still needed before the seeds will sprout.

There’s barely time to get those seeds growing this spring. Two months in moist warmth followed by 2 to 3 months in moist peat and perlite in the refrigerator should awaken them. It’s exciting to check the bag in the refrigerator because, once mechanical and chemical barriers to germination have been overcome, a bag of seeds is usually transformed to a bag of white root sprouts, all at once, as if a switch had been turned on.

The Rabbi Multiplies

I’ll have to make up some extra peat-perlite mix. Cutting all the vertical shoots of Rabbi Samuel fig espalier back to the horizontal arms of the permanent “T” framework have yielded a pile of long stems. I can’t bear to throw them away because every foot-long section has the potential to make a whole new plant.

Rabbi Samuel fig, pruned

The rooting media for these hardwood cuttings? Peat and perlite again. A bunch of the stems in a deep pot with just their top buds up out of the peat mix should sprout and root by spring.

Not sure what I’ll do with all the resulting fig plants.

So Many Roses, I Hope

I’m also not sure what I’ll do with all the anticipated rose seedlings, especially since I’m not even sure of their species. I did telephone the public works department of the Rhode Island town where the roses were planted and was told that they were Rosa rugosa. I think they are wrong.

Fig cuttings

No matter: Rosa rugosa is one of the most fragrant roses with deep pink, sometimes white, flowers that are borne all summer long. Also, like dog rose, with nice, fleshy hips, good enough fresh and excellent for jam and tea.
