DRY WOOD, & AUTUMNAL AIR

September 7, 2016/3 Comments/in Design, Flowers, Gardening, Planning, Soil, Vegetables/by Lee Reich

Passionflower to the Rescue

When I began, many years ago, to heat my home with wood, I struggled to get the driest possible wood, finally building a 60-foot long woodshed beneath which a double row of logs basked in the direct hit of sunlight from the south. I more recently learned that firewood can be too dry, which is when moisture drops below 15 to 20 percent. Bone dry wood can’t get enough oxygen for a clean, efficient burn, so smoke, within which is locked the potential for rendering additional heat, is produced; pump enough oxygen into the mix, though, and you get an inferno that can damage a woodstove.
   So — and here’s the plant-related part — rather than tear down or put siding on my super-drying woodshed, I put some heat loving vines to climb and provide some shade on the south face. Sections of hog-fencing temporarily hung on hooks just below the roof in front of each of the 8 foot bays support the vines.
   Maypop, Passiflora incarnata, is an ideal candidate for this location. (Learn more about maypop — a whole chapter’s worth! — Uncommon Fruits For Every Garden.) It’s an herbaceous perennial, emerging early each June to grow vigorously into lanky vines 10 or more feet long. Maypop is a hardy species of passionflower, and a few weeks after emerging, the intricate blue or white blossoms unfold along the stems. White maypop flower
   Flowers would be enough, but there’s more. A few weeks later, those flowers morph into egg-shaped fruits: tropical passionfruits this far north. Maypop fruit
   In southeastern U.S., maypop, with its spreading root system, is considered a weed. This far north, maypop will enjoy the extra heat of the microclimate at the south face of the woodshed. The woodshed itself will contain the plant in its travel northward. The lawnmower will contain the plant in is travel southward. Let it spread all it wants east and west along the base of the shed.

Morning Glory & Kin for Quicker Effect

    In spring I planted a maypop plant at the foot of four of the woodshed bays. As a perennial, maypop needs time to get established. Because I went to the trouble of hanging a trellis from each of the bays, I wanted something to clothe even this summer.
   Enter the Convolvulaceae family, which counts morning glory among its kin. Less know, but also kin and vines with pretty flowers, are cardinal vine and moonflower. I figured that some member of this family could accompany maypop in each planting hole. Morning glory against woodshed
   All three Convolvulaceae family members grow vigorously so could provide good coverage for the woodshed. They also integrate well with each other, design-wise. Morning glory wakes up early, its sky-blue flowers opening each morning to foreshadow the blue sky that lies ahead. (The flowers remain furled under overcast skies.) Once the sun rises high in the sky, fire-engine red flowers of cardinal flower take the torch for the remainder of the day. As night falls, moonflowers’ large, white trumpets open and emit their sweet scent.
   This year, those annual vines grew so vigorously that they stunted their companion maypops. Next year will be better. Also, a couple of plants of another vine, native and somewhat decorative, have tried to get a foothold in the planting. Poison ivy, you’re not welcome here.

Autumnal Readiness

    Morning glories have started lingering later into the mornings, a sign that autumn is approaching. I’m also getting signals — a softness in the air and an occasional chill, a slight chill — of autumn’s approach. Those signals do not have me lingering late in the morning, though.
   The imminence of autumn has me scurrying around making sure all is copacetic in the weeks to come and on into next year. Turnips and winter radishes have been thinned. Cabbages, Chinese and European, transplants are growing well, hinting at crocks of kim-chi and sauerkraut to come. Onions have been harvested and woven into ropes for storage, now in the garage, later in the basement. Winter radishes and Chinese cabbages
   Any cleared vegetable bed is given a thorough weeding and then an icing of an inch depth of compost. That compost will snuff out small weeds attempting to sprout below. Additionally, it will feed soil microbes which will, in turn, feed plants for at least a year. I’ll sow arugula, mustard greens, and “spring” radishes in the bed which I recently cleared of sweet corn, weeded, and composted.
   A couple of sites have been prepared for two new trees. “Prepared” is too fancy a word; all I did was pile mulch on the ground at both locations. The mulch will kill existing vegetation and leave soft, moist ground for easy planting in October.
   Autumn will be bountiful and next year will be a good year.

ROT AND FLOWERS

August 11, 2016/0 Comments/in Flowers, Fruit, Gardening, Pests, Planning/by Lee Reich

Brown Rot Strikes Again

   The plan was for me to be now sinking my teeth into the soft, juicy, rich flesh of my Oullins golden gage plums. The tenuous start this past spring, with a freak late freeze that sent temperatures plummeting into the low teens, had me worried. The trees shook off the cold and, when warmer weather returned, burst into snowballs of white blossoms. Tiny fruitlets that followed those blossoms have swelled to the bountiful crop now dangling from the branches.
   The plan has been foiled — by brown rot disease. Almost every plum, just as its skin starts to shade towards ripeness, becomes spotted with fuzzy, gray droplets that, with good weather (good for the fungus, that is), soon covers the fruit. Brown rotted plum fruit
   Brown rot was not unexpected, and a counterattack was planned. All through spring, before blossoms even unfolded, I doused the plant with insecticide and fungicide sprays. Insecticides help control brown rot by preventing insects, most notably plum curculios, from laying eggs in the developing fruitlets. Even if the egg-laying itself doesn’t cause the fruit to drop, holes left behind provide easy entrance for the brown rot fungus.
   Perhaps I was too lenient, using relatively benign (to us humans, that is), organically approved sprays. ‘Surround’, a commercial formulation of kaolin clay for the insects. And sulfur, a naturally occurring mineral, for the brown rot fungus. Brown rot mummy
   That’s not all. Gathering up infected fruits cuts back the number of new disease spores that waft among the branches looking for new fruits to infect. In fall and winter, those infected fruits are easily recognized as blackened, dry “mummies.” They lose their dryness and come to life, fungal life, with spring’s warmth and moisture. I’ll gather them up also. I’m hoping my ducks develop a taste for the fresh, dropped, rotten fruit; so far, they seem to be picky eaters.
   My late winter pruning of the trees should also have helped reduce brown rot disease. Removing enough stems and limbs to allow those that remain to bathe in light and breezes allows for quicker drying from dew or rain.

The Disease Triangle

    Three conditions must be satisfied for any disease, whether in animals or plants, to take hold: inoculum must be present, the host must be susceptible, and the conditions must be suitable for disease development. Check, check, check for my Oulin plum (a susceptible host plant) getting brown rot here in the Hudson Valley, throughout most of the humid eastern U.S., in fact. We have plenty of wild and cultivated plums and related plants here to provide brown rot inoculum from infected fruits, and the weather is usually just about perfect (for the disease, that is).
   But Oullin isn’t the only great-tasting plum. How about a less susceptible host variety? Fungi are picky eaters, and varieties of plants vary in their susceptibility to specific diseases.(Unfortunately, most gage-type plums, which are heart-shaped, with greenish flesh, are very susceptible to brown rot.) Infected plums on tree
   My plum trees are grafted to multiple varieties. The variety Shiro also finds a home on the tree grafted to Oullin. This year, and in years past, Shiro seems to be somewhat resistant to this disease. And I see that Cummins Nursery has a variety called Jam Session that also is resistant. This past spring I also planted the varieties Alderman and Superior, which are American hybrids with some alleged resistance.
   As consolation, plums are, at least, less susceptible to this scourge than are peaches and apricots.

Flowers to the Rescue?

    I’m planning and planting for flowers for next season and for years to come, with perennials.
   I could, of course, just purchase some potted plants to plug into the ground now or next spring. I could buy seeds and sow them next spring. Instead of those two options, I’m sowing seeds now, a time when, admittedly, there’s not that frenzied urge to plant seeds as in spring. Black-eyed Susan Purple coneflower
   One packet of seeds can — should — result in oodles of plants, plenty to plant and to give away. Sown now, the seeds should grow into plants that will be large enough to weather autumn, then winter’s, cold. Plants should also be large enough to flower next year. Their experience of cold, known as vernalization, will further coax them on to flower. Spring sown perennial flower seeds often don’t flower their first season, no matter what their size, because they have yet to be vernalized. Liatris
   I’m sowing purple coneflower (Echinacea), black-eyed-susan (Rudbeckia), and blazing star (Liatris). They’re all in the daisy family, a family known not only for its good looks but also for providing nectar to attract and help support beneficial insects. If I plant enough, perhaps the increased number of beneficial insects will significantly decrease the number of plum curculios and other plum fruit insects resulting in, because of less insect scarring of fruit, significantly less brown rot of my plums.
   It’s a stretch but the flowers, anyway, are very pretty.

GOOD SUMMER BLUES

July 7, 2016/1 Comment/in Flowers, Pests/by Lee Reich

Plan Realized

Almost two years after my plan was conceived . . . success. Looking across rows of tomatoes, corn, onions, and kale in my vegetable garden, I see tall, blue spires of delphiniums that have finally come of age.
The spires required some effort. Coarse roots of the seedlings called for an extra dose of care. Potting soil could easily fall from the roots, exposing them to drying air, as the seedlings were successfully moved to larger quarters.
Delphinium at back of garden
And then, once seedlings were planted out just beyond the western fence of the vegetable garden, my chickens threatened them. The poultry enjoy scratching for insects near the bases of plants. Doing so weakens larger plants, even woody shrubs; doing so can kill tender young seedlings. Chicken wire laid on top of the ground let the delphinium plants grow up through the 1 inch openings while preventing chickens’ scratching.

Planning for Future Blues

    The delphinium show will end any day now, especially with this hot weather. It’s hard to let go of the show — and I don’t necessarily have to. Sometimes a second, later show can be coaxed from the plants. If the stalks with spent blossoms are cut back to the bottom whorl of leaves, new flower stalks will spring forth that should bloom again later this season.
Rustic gate & delphinium
   Good growing conditions help bring on this second show. That means rich soil and water, as needed. These I have provided for my delphiniums in the form of compost topped with a leafy mulch, and drip irrigation. “Good growing conditions” also means cool growing temperatures, which I cannot provide.
   Even under the best of conditions, delphiniums, although perennials, are short-lived perennials. Before next spring I’ ll get some fresh seed — freshness of seed is important for good germination — and start a bevy of new plants. For the freshest seed possible, I’ll collect them from my own plants by gathering whole stalks when they are partly dry and then shaking out seeds. Planted immediately and kept slightly cool, they should sprout in a few weeks and flower next June. Sometimes they even self-sow.

Doing What Good Gardeners Do

Self-sown delphinium seedings are most welcome; not so for many other self-sowers, that is, weeds. Now is the time when many summer weeds pick up steam. Now is also the time when good gardeners and mediocre gardeners take different paths.
I want to be a good gardener so I’m planning, immediately after I dot the last word of this report, to go out and weed. My garden is generally not very weedy, mostly because I never — yes, never — till or otherwise turn over the soil. And because I snuff out small weeds with an annual mulch of compost in planting beds and wood chips in paths. (Mulching and never tilling also bring many other benefits, such as encouraging more vibrant soil life, better use of water, and, well, not having to till.)

Purslane

   Still, weeds have made inroads. I can’t help but remind myself that every weed that goes to seed could self-sow to spawn myriad more of the same — for example over 50,000 seeds per pigweed plant, or almost 20,000 seeds per dandelion plant! Perennial weeds, unchecked, build up energy reserves in their roots and spread by traveling roots, as well as by self-sowing. Checking growth of these weeds now makes for a bountiful fall garden and much fewer weeds next year.
   Mostly, I just bend over and pull out weeds, coaxing them out, if need be, with my hori-hori knife. Where weeds are too numerous to make one-on-one treatment too tedious, I slide my winged weeder or wire hoe along the ground to dislodge them all at once. I gather up most pulled and hoed weeds and cart them over the the compost. Sweet revenge: light-, nutrient-, and water-stealing weeds recycled into garden goodness.
   Amongst the weedy interlopers are some worth separating out, for eating. Among my favorites are pigweed, which makes an excellent cooked green. And purslane, very healthful and tasty if doctored up correctly, good suggestions for which can be found in Foraging & Feasting: A Field Guide and Wild Food Cookbook by Dina Falconi and Wendy Hollender.

SMALLER IS BETTER

June 22, 2016/12 Comments/in Flowers, Fruit, Gardening, Pruning, Soil/by Lee Reich

Small Plants

Weeding. Planting. Harvesting. Making compost. Spreading compost. Staking. Pruning. Mowing. These are some of the activities I share with my plants this time of year. But, as Charles Dudley Warner wrote in his 1870 classic, My Summer in a Garden, “Blessed be agriculture! If one does not have too much of it.” Which prompts me to weed, plant, harvest, etc. most efficiently.

Bush cherry, 1 month after planting

   Let’s take a look at some of the trees and shrubs I’ve planted this spring: Romeo and Carmen Jewel bush cherries, aronia, Grainger shellbark hickory, Great Wall Asian persimmon, Rosa canina, and Hidcote St. Johnswort. Just getting all those plants through their first season could entail lugging around many buckets of water. But it doesn’t.
   Large plants of any of these could possibly be sourced but I chose small plants. And that was the first step to making sure that, paraphrasing C. W., I wasn’t overburdened with my agriculture.
   With smaller root systems, small plants establish more quickly than large plants. In fact, establishing more quickly, smaller plants usually outgrow their larger counterparts after a few years.
   A tree or shrub with a two-foot diameter root ball might require 3 gallons of water weekly until enough roots foraged out into surrounding soil to make the plant self-sufficient water-wise. Two cups of water weekly is enough to keep my newly planted Romeo bush cherry alive since its move from the 4-inch-diameter pot it previously called home.
   By the end of this growing season, all these small plants will be firmly established and pretty much water independent. They’ll get supplemental water only if there’s any extended dry spells in their second season.

Small Planting Holes

Water for these young plants isn’t all about watering per se.
Site preparation is also important. Not that, as older gardening books used to suggest, it’s “better to dig a $50 hole for a $5 tree than a $5 hole for a $50 tree,” the dollar amounts reflecting the size of the tree and the hole. No need for such heroic measures. Digging that large a hole breaks up the capillary channels in a large volume of soil, leaving large air gaps in the soil through which water just runs down and out. Capillary channels can move water, down, up, and sideways.

Shellbark hickory, 1 mo. after planting

Better — and easier — is to dig a hole only twice as wide as the spread of the roots or root ball (if potted), and only as deep as needed so a plants sits at the same depth as it did its pot or the nursery.
   With few exceptions, no need to add compost, peat moss, fertilizer, or anything else to the soil in the planting hole. After all, the expectation is for roots to eventually extend well beyond the planting hole. Create excessively posh conditions in the hole and roots have no incentive to leave. Then roots grow only in their planting hole, not beyond.
   All soil goodies are best lathered on top of the ground. My first choice is for compost. Nutrients and beneficial soil organisms within the compost, over time, meld with the soil below. Compost also softens impact of raindrops so that water can percolate down into the ground rather than running off in rivulets — lessening my need for watering.
   A mulch is the final icing on this layer cake. I’ll top the compost with wood chips, leaves, straw — any weed-free, organic material. This top layer further softens the impact of raindrops, keeps compost moist and vibrant, and slowly decomposes to nourish soil microorganisms and then the tree or shrub.
   Yesternight’s rain or 1.25” did a week’s watering for me. A good rule of thumb is to apply one-inch of water once a week, or, equivalently, three-quarters of a gallon per estimated square foot spread of the roots. Potted trees and shrubs need that one-inch of water spread over 2 or 3 days of the week for a couple of weeks after being planted, until their roots begin to spread into surrounding soil. Larger tree and shrub transplants need more water, more frequently, for a longer period of time.

Followup on Drastic, and Less Drastic Pruning

I recently wrote of “renovating” my old lilac shrub, a no-brainer as far as pruning. You just lop each and every part of the plant right to the ground. My fears that such drastic pruning might also kill the plant were unfounded. Already, new sprouts are growing from the sawed off remains of the plant as well as from some distance away. All that’s needed now is to choose which sprouts to keep to grow into a whole new shrub.

Lilac regrowth from stump

My blueberry shrubs also received more drastic pruning than usual. To lower their height and to encourage and make space for younger, more fruitful stems, I lopped a few of the oldest stems of each bush right to ground level. Like the lilac, new sprouts soon rose from ground level.

Blueberry, new sprouts

Late next winter, I’ll save the most vigorous of these new sprouts and lop the rest of them all the way to the ground. And, of course, again lop to ground level some of next year’s oldest stems.
Such pruning (covered in my book The Pruning Book) keeps blueberry and lilacs perennially renewed, without any stems that are too old to flower or fruit well as well as plenty, but not too many, young replacement stems for the future.

MAKING SCENTS (AND A BOOK GIVE AWAY!)

May 26, 2016/8 Comments/in Books, Flowers, Fruit, Gardening, Pruning/by Lee Reich

Reader Alert: Invasive Plant

    The sweet scent practically bowled me over. My friend, walking with me along the nearby rail trail, characterized the aroma as citrus-y rather than sweet. Either way, the aroma was delicious and welcome. Too bad the source of the scent, autumn olive (Elaeagnus umbellata), is a plant so reviled. Autumn olive blossoms
   “Too bad” because the plant also has other qualities. The olive-green leaves lend a Mediterranean feel to any setting. Microorganisms associated with the shrub’s roots garner nitrogen from the air to enrich the soil. And come early fall, the plants are loaded with delicious and nutritious, small, red (sometimes yellow) berries.
   Alas, this non-native plant grows too easily, frequenting fields and waysides. It’s deemed invasive, which it is . . . but?
   Autumn olive fruit (Autumn olive is often confused with Russian olive, E. angustifolium, a close relative that is more tree-like, less invasive, and with sweet, olive-green fruits. Another equally attractive, fragrant, tasty, and soil-building plant is gumi, E. multiflora, not well known but closely related to the other “olives.”)

And Yet Another Invasive

Soon, by the time you read this, the rail trail and elsewhere will be suffused by another pleasant aroma, that of honeysuckle. These flowers are also followed by red berries, but they’re not edible. (Other honeysuckle species do yield edible berries, an up and coming fruit called haskaps.) Honeysuckle flower
How could anyone not like a plant with a name like “honeysuckle?” A lot of people don’t like honeysuckle because it too, despite its qualities, is invasive.

You Call This Renovation

    Before anyone attacks me for heaping praise on invasive plants, let’s sidle off the rail trail and back to the home front, where yet another delicious scent fills the air. This one wafts from a plant that, unlike autumn olive, Russian olive, and gumi, is not invasive and is truly in the olive family: lilac (Syringa vulgaris).
   Actually, for years now, my lilac bush has not been perfuming the air as much as it should. The plant is old, my guess is over 50 years old. Not that age alone is responsible for its poor showing. Lilac, like other shrubs, have long-lived root systems. No stem ever develops into a permanent, long-lived trunk and — important for all flowering and fruiting shrubs — after a certain age stems can’t keep up the flower production of its youth.
   The way to prune any flowering or fruiting shrub is by a renewal method. You cut down some of the oldest stems that are no longer performing well. And then you thin out — that is, reduce the number of — some of the youngest stems so that each can develop to its fullest potential without being crowded.
   How long an old stem is worth keeping and how many new stems spring up each year from ground level depends on the kind of shrub and the growing conditions. A highbush blueberry stem, for example, retains its youthful fecundity for about 6 years; a raspberry, for two years.

Young lilac, old lilac, renovated lilac

I’ve pruned my lilac over the years, but — I have to admit — never cut the old stems close enough to the ground nor thinned out the many young stems sufficiently. (My excuse is that the dense crowding of 5-inch-diameter stems made cutting difficult, the difficulty made more so by the haven they provided for poison ivy vines.)
   A non-blooming lilac shrub isn’t worth keeping, so drastic renovation was in order. This treatment can be applied to any old, decrepit shrub. It’s easy. All that’s needed is to cut everything to the ground. Which I did.
   My lilac’s stumps gave evidence to the shrub’s poor showings over the years with their many thick yet half-rotten, old stubs. Shrubby stems, as I wrote, just aren’t meant to live that long, and over time can’t support good flowering.
   If all goes well, new sprouts should soon poke up from ground level, vigorous new sprouts because they’ll be fueled by a large, old root system. It’ll be a few years before any of those sprouts get old enough to start flowering. But I’ll make sure to thin them out so each has room to develop. I promise.

APRIL SHOWERS BRING . . . NO!

May 12, 2016/5 Comments/in Flowers, Gardening, Planning, Soil/by Lee Reich

Don’t Go With the Gut

   “April showers bring May flowers.” Where? Not here. I had many years of gardening under my belt before I realized the falsity of that little ditty. Yes, it happens to be raining as I write these words at the end of April. But generally, April is dry, and todays’s rain amounted to a mere quarter-inch.
   For years, I would sow radishes, lettuce, arugula, and other early, cool season vegetables in April, and figure “April showers” would take care of watering needs. Which they did not. With frosts still likely around here, April was too early to get the drip irrigation going. So watering vegetable beds requires tedious lugging of hoses, making sure, as I pull on them, not to knock over plants or mess up carefully formed beds.
Watering wand Hand watering also required patience. A light sprinkling of the ground does nothing but wet the surface fraction of an inch. If you care to know, the amount of water needed to wet a soil about 6 inches deep is 3/4 of a gallon per square foot or, equivalently, a one-inch depth of water. And said water needs to be applied slowly enough to percolate into the ground rather than running off elsewhere.
   Fortunately, with cool temperatures and plant growth only just beginning, much of the moisture from previous months’ rain and snow still sits in the soil. The surface often looks dry while moisture is sufficient below. So all that’s needed is to keep the soil moist from the surface to a depth where the ground is still moist.

Measure

    Eyes or the gut are not reliable indicators of when to water. Sometimes I’ll just poke my finger into the ground to assess moisture level. But does it really feel wet, or does the soil feel cool because it’s April?
   All that’s needed are your hands for the more accurate “feel method” of soil moisture determination. For this method, you need to know your soil’s texture; that is, is the soil a sand, a loam, or a clay? Crumbling it, feeling its slickness, and attempting to form it into a ball or a ribbon gives some indication, depending on the texture, of moisture content (see http://www.ext.colostate.edu/sam/moisture.pdf for details).
   All sorts of high-tech soil moisture measuring devices are available: electrical resistance blocks, tensiometer, time domain reflectometer, neutron probe, and more, all beyond the wallet and accuracy required by of most gardeners. pH, moisture testor
   On the other hand, inexpensive soil moisture meters are readily available. What they lack in accuracy they make up for in convenience. Sliding the thin, metal rod into the ground gives a pretty good, qualitative measure of moisture anywhere from just below the surface to the length of the rod, which, depending on the device, is 8 to 12” inches long.
   Watering is an important key to success in gardening, and for $10 to $50, these relatively moisture meters are well worth the money. The more expensive, previously mentioned monitors can be left in the ground. The inexpensive meters must be removed and their probes cleaned after each measurement.

Indoor, April Showers Bring . . . Yes!

Even if April showers do not bring May flowers, April — the month — does bring a few May flowers, but mostly flowers in June and beyond. That’s because April is the month when I sow many flowers for transplanting out into the garden after warm weather settles in. On the slate for this year are Lemon Gem marigold, sunflowers of all stripes, chamomile, moonflower, morning glory . . . (Where am I going to plant all these flowers? Spring’s got a hold on me.)

Tussler Was Correct After All

The ditty “April showers bring May flowers” really does have some truth to it — if you’re in the UK, where the ditty originated. There, the northward moving jet stream picks up more and more moisture as it travels across the Atlantic Ocean; the result is rain by the time the winds reach the UK. (On this side of the “pond,” the jet stream, traveling across land, has picked up relatively little moisture.)
So Thomas Tusser, who allegedly penned “Sweet April showers / Do spring May flowers” in the 16th century (in A Hundred Good Points of Husbandry), was not wrong, for Great Britain. Here, we have to water in April. But not too much.

IT’S ALL ABOUT THE WEATHER

April 22, 2016/0 Comments/in Flowers, Fruit, Gardening, Pruning, Vegetables/by Lee Reich

Snow!!

The talk of the town these days is the weather. In this town, at least, and other towns throughout the Northeast. After a relatively snowless winter punctuated with warm spells, spring knocked early at winter’s door and was let in. Even I, who try to be guided by the calendar rather than my gut, succumbed, planting peas a full two weeks earlier than my usual date of April 1st. Flowering trees and bushes — and more importantly, those whose flowers later morph into luscious fruits — similarly fell prey to spring weather’s apparent arrival.
As I write, snowflakes tumble down from a gray sky, adding to the three inches of snow already piled onto spring green grass. Temperatures tonight and tomorrow night are predicted to drop near 20 degrees F. We’ve all been duped!!

Nanking cherry flowers with snow

   I’m most concerned, and least able to do anything about, weather’s effect on my fruit trees and bushes. Nanking cherries were in full bloom a few days ago, a full two weeks earlier than average. Asian pear flower buds look about to pop open, blueberry buds have fattened in preparation for opening , and black currants and gooseberries have almost fully leafed out.
   Options available to commercial orchards are not feasible in backyards. Such as sprinkling plants with water so that the heat of fusion released as water freezes keeps buds warm; you can’t stop sprinkling until weather warms enough to melt all ice. On clear, cold nights, heavier, cold air sinks but can be warmed by mixing in warm air from higher up. Not many backyard gardeners have wind machines or are willing to have a helicopter hover overhead all night pushing down warmer air.
   What we backyard growers can do that orchardists cannot, feasibly, is to snug a few small plants — bushes and dwarf trees — beneath a blanket. (Except that I have a lot more than a few small fruit plants.) That’s about it. Besides keeping fingers crossed and hoping for the best.

Winter Cold!!

Peach flower buds, dead

Peaches are famous for their early blossoming, so I was especially worried for them. My peach tree spent its first few years in a large pot which could be conveniently lugged into the garage whenever cold weather threatened its blossoms.
No need to worry this year. I checked the fat, flower buds, and they are already dead. Winter’s cold and/or fluctuating temperatures evidently had already done them in.

(Too) Early Peas

    My early planted peas took advantage of the last couple of weeks of balmy weather and sprouted quickly. Temperatures near 20° will surely freeze those sprouts. They might resprout from protected buds below ground, or not.
   I nudged ol’ man winter aside and created a warmer microclimate over the sprouts by putting up metal hoops covered with row covers over them. They may have been better off with the blanket of snow tucked all around them. Then again, the snow cover might settle too much, or blow away.
   In a few days, I’ll see how the peas fared. Worst case scenario: replant.

Not Climate Change

“Climate change” is the battle cry for this whacky weather. But is it really so whacky?
As far as the cold, the average date for the last killing frost of spring in my garden is around the third week in May. The key word here is “average.” Looking at a tabulation of percent chance of cold temperatures on various spring dates (davesgarden.com), on average there’s a 50% chance of the thermometer hitting 24° on April 14th around here, a 10% chance on April 27th.

Peas under tunnels & snow

   “Frost” means 32°F. For that magic 32°, which is lethal to tomato and pepper seedlings but of no consequence to cabbage and onion transplants, there’s a 50% chance of that temperature on May 13th, even a 10% chance on May 27th.
   Of course, temperatures in my (or your) garden could be a few degrees different from those at nearby weather stations, which supply those averages. Still, looking back at my own records, while last year Nanking cherries blossomed here on May 2nd in 1999, they blossomed on April 18th in 2004, on April 26th in 2012, and on March 29th in 2015.
   So it seems like whacky weather is the norm. Except this year, it does still seem that the early warming was slightly earlier, and the later cold — 15°F, now, the day after the snowfall — more intense. Then again, Nanking cherries have never failed me.

FAILURES, SUCCESSES

April 7, 2016/5 Comments/in Flowers, Gardening, Houseplants, Planning, Vegetables/by Lee Reich

Can Anybody Tell Me How to Grow This?

Quotes about the rosy side of failure are not hard to find. ”Failure is the opportunity to begin again more intelligently,” wrote Henry Ford. John Dewey wrote that “Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.”
No, Mr. Dewey; in gardening, at least, failures are more instructive than successes. Put a seed into the ground and that seed has millions of years of evolution prompting it to grow. True, you can fail if starting with old seed, or soil so cold that the seed rots before it grows, or compacted clay soil that suffocates the seed. But generally, gardening is not that difficult. And generally, it’s hard to fail. So success is the norm, no matter — within reason — what you do.

Jasmine — no flowers, again

   For someone who pays particular attention to their gardening (and writes about it!), occasional failures are surely opportunities for learning and for success. Not so, for me! With my jasmine (Jasminium officinale) plant, at least.
   I’ve grown this jasmine for many years. In its early years, the plant was a snowball of sweet-smelling white blossoms in late winter. Over the years, flower production has petered out, to the point where the plant coughs forths just a few blossoms here and there.
   Many plants need a cold period to induce flower buds. Over the years, my jasmine has spent fall outdoors or in my cold basement (near a window) or in my cold greenhouse (minimum temperature 37°F).
   Many plants need a dry period to coax on flower buds. Over the years, the soil in which my jasmine grows has been kept through fall just moist enough to keep the plant from wilting.
   Some plants need a period of both cold and dryness for flowering. Check.
   Besides all these treatments, I have tried various suggestions from others, including professionals who sell jasmine plants awash in bloom from their commercial greenhouses. No pruning after August. No artificial light in autumn. Generally good growing conditions all through summer. High phosphorus fertilizer. Check. Check. Check. Mmm-check. (I’ll admit I neglected the high phosphorus fertilizer. With ample compost, my potting soil has ample phosphorus, or so I assume.)
   Now, in its thirteenth year here, jasmine has again not bloomed. I’ve learned nothing. Again, I’m threatening to walk it to the compost pile, counterbalanced by inklings of desire to give it one more try. (The phosphorus fertilizer, perhaps.)
   My one possible consolation comes from reading a quote by George Bernard Shaw, “My reputation grows with every failure.”

Cardoon Futures

Cardoon I saw in Oregon

    Enough self-flagellation. Let’s balance that out with a couple of successes, one the result of my doing, not driven by millions of years of evolution.
   I’ve written previously about cardoon, a so-so vegetable but a fine ornamental. (True, many other people sing passionate gustatory praise for cardoon.) As a perennial, cardoon grows only leaves its first year from seed, which is fine if your eating it, because the leaf stalks are the edible part. The tall, spiny, olive green stalks, like a Mediterranean celery on steroids, also are dramatically ornamental in their own right.
   The flowers, poised like cerulean bottlebrushes atop their tall — five feet high, or more — flower stalks are the real show, though. And, in that second year and beyond, you still get the whorls of giant leafstalks rising up from around the base of the plant.
   Cardoon can’t tolerate winter cold below about 10 or 15°F, so it’s not winter cold-hardy here. Too much moisture around the crown of the plant might also help do it in during winter.
   Last fall, after cold had settled into the ground, with about an inch depth of frost in the soil (towards the end of December) I cut back the top of the plant, then piled dry leaves over it. An overturned, 2-foot-diameter, plastic planter over the leaves kept them in place and added a bit more insulation and, also important, kept rain and snowfall off the plant. The drainage holes around the bottom (now the top) of the planter’s side allowed for some air movement within.
   A week or so ago I tipped off the planter and untucked the leaves from around the plant. It was important to get to the plant before warmth got it growing, in which case the once-shaded, tender leaves would burn in the sunlight and be susceptible to frost. The leaves, just starting to emerge from the decapitated plant, looked healthy and ready to stretch out and grow after their winter’s rest. I look forward to the flowers.

Really Red Deer Tongue

Winter lettuce in the greenhouse is my other success. While many lettuces have begun to go to seed, especially those sown earlier in fall, the variety Really Red Deer Tongue just keeps making new leaves in spite of it’s having been sown in early September of last year. The leaves, as the names says, are red and, I suppose, the shape of a deer’s tongue. I don’t normally eat deer tongues, but these leaves taste good. Lettuce, Really Red Deer Tongue

FLOWERS, ONE VERY, VERY SPECIAL

My Quest, Fulfilled

    For thirty years, I’ve longed to catch at least a glimpse of Himalayan poppy (Meconopsis betonicifolia) in blossom; finally, yesterday, I achieved that goal. I wish I could say that I braved high seas to get to India, then traipsed across increasingly mountainous plains, and finally clawed my way up some jagged peak before coming face to face with the blossom. No, I was in Philadelphia, at the the Philadelphia Flower Show, when I remembered that nearby Longwood Gardens puts on a show of Himalayan poppies each year in early March. All that was needed was to brave traffic for the one hour drive (40 minutes without traffic) over to Longwood.
   It was thirty years ago that expert plantsman and orchid hunter Norman Kellar told me of his admiring the blue poppy’s sky blue blossoms, both in reality and in reflection, from across a pond in England. The flowers, he said, are the purest blue of any flower. Did Longwood’s show meet up to my thirty year buildup? Yes. The petals, delicate as tissue paper, are a sky blue, the bluest I’ve seen in any flower. The center of each nodding blossom is lighted by a bottlebrush of orange stamens.
   So why haven’t I, and why didn’t Norman, just plant Himalayan poppy to enjoy in our own backyards? The plant thrives — no, survives — only where summers remain cool. Above 70°F, the plant can’t photosynthesize, so it starves. I’ve tried growing blue poppy in the past. Each time it grew fine until July’s summer heat caused it to collapse, dead.
   Longwood’s plants avoid heat by starting life in Alaska, where the plant thrives. Young plants are shipped in from Alaska in the fall and kept dormant in cold storage. Brought into Longwood’s cool (50-60°F) conservatory in January, they slowly awaken and, finally, blossom in March.
   My plan is to sow seeds in potting soil in a seed flat in late summer, then water and chill the flat in a refrigerator for a few weeks. (Some seeds need that chilling to break their dormancy or speed germination. Whether or not blue poppy needs it, a few weeks of cool temperatures will do no harm.) By early fall, the seedlings should be up and growing, which they can do outdoors and then, if needed, in the greenhouse. When cold temperatures and low light slow the plants into dormancy, I’ll store the pots at a cool location in my basement.
   Finally, in January, I’ll move the plants to a sunny window to begin growth. That time of year, even sunny windows don’t get too hot. Come March, with luck, a green thumb, and clicking my heels together three times, the sky blue blossoms will be staring at me — or out the window.
   My first sighting of “our” bluebird was a week ago. Next year, looking at blue poppy plants blossoming at a window and bluebird outside the window would be a very nice prelude to spring.

Three Perennial Treats

    Flowers have never been a focus of my gardens, and less so as each year goes by and I pay more attention to more enduring elements of my yard, such as fences, arbors, hedges, trees, and walls. Still, some flowers, such as the blue poppy, are worth the effort.
   In years past, seed flat upon seed flat of all kinds of flowers would occupy growing space. This year: Just one flat of perennials, that one flat with four mini-furrows, one for dianthus, one for cardinal flower, one for foxglove, and one for purple coneflower. Each of those mini-furrows will yield enough seedlings, to be carefully separated then planted in individual cells of potting soil to grow into plants, for transplanting, for a nice show this summer and beyond.
   The main attraction of the dianthus, for me, is its fragrance. From descriptions, the Riesen Giant Superb Mix Dianthus I just sowed seems very similar to the Dianthus caryophyllus that I grow in the greenhouse except, in contract to its greenhouse cousin, this dianthus is allegedly cold-hardy outdoors in Zone 5. (I have the feeling that both dianthus’s may be the same; the “giant” and “superb” in the name hooked me.)

Cardinal flower

Cardinal flower is perennial, but not a long-lived one. It thrives in wet areas and, in congenial locations such as, I hope, here, will self-sow. This flower first caught my attention when its spike of fire engine red blossoms stared out at me from deep, deep shade. Deep shade is not home to many colorful flowers.
With spikes of pastel-colored blossoms, foxgloves have a charm evocative of blowsy cottage gardens. They also are only weakly perennial; but they self-sow readily. Their popping up willy-nilly around any garden from self-sown seeds adds to their blowsy effect.

Foxglove

One downside to foxgloves is that flowers all line up only on one side of the flower spike, facing the sun. Except for the Excelsior series of foxgloves, which is what I have sown this year. It will be interesting to see how thoroughly the blossoms embrace the spikes and then how future years’ blossoms, from self-sown seedlings, display themselves, especially since they’ll be mating with run-of-the-mill foxgloves already growing here.
Nothing special about coneflowers. They’re native, easy to grow, and common. They’re also pretty.

Back to Fruit

Enough with the frills! Back to pruning kiwifruit and grape vines, blueberry, gooseberry, and currant bushes, and the plum, pawpaw, mulberry, a pear trees. They are pretty, too, and give me fruit.

TOTIPOTENT — NOT WHAT IT SOUNDS LIKE

March 15, 2016/2 Comments/in Flowers, Fruit, Uncategorized/by Lee Reich

Cells Beget Plants, or Animals

   As I strode out to the garden today, the word “totipotency” was forefront in my mind. No, I wasn’t thinking of myself as “all powerful,” which is what totipotent (Latin totus=whole, potent=powerful) might seem to mean.
   Totipotency is the ability of any cell in an organism — you, me, my dog Sammy, my rose bush — to potentially give rise to any other kind of cell of that organism, or to a whole new organism, a clone of the original. Under the right conditions, you could put one of your skin cells in the right environment, and have those cells grow into new skin, toes, eyes — even a whole new you. Fortunately, nobody has yet figured out how to do that with a human.
   (What I wrote is not exactly true. Not every cell within an organism is totipotent. In organisms that reproduce sexually, egg and sperm cells — the germ cells — have only half their complement of genes, so these particular cells can’t be cloned to reproduce non-germ cells or whole organisms.)
   Back to the garden and totipotence . . . Using random plant parts to make whole new plants is nothing new to most gardeners. With stem cuttings, for example, you put a stem into a suitable environment, and it’s induced to grow roots at its base and new shoots, followed by flowers and, perhaps, fruits, above ground. With leaf cuttings, all these new parts spring from a mere leaf.
   Stems and leaves are more than just a few cells. More specialized, but still feasible, is cloning with just a few cells: so-called micropropagation or tissue culture. A few cells are removed, usually from a growing point, and then, under sterile conditions, put into a petri dish containing a medium to supply nutrients and a balance of plant growth hormones. The cells multiply without differentiation into anything special until they are transferred to another medium, this one with an altered balance of hormones, that induces cells to differentiate into leaves and roots. After a period of growth, the plantlets graduate to real soil.
   Micropropagation is a way to create many new, pest-free clones quickly and from a minimum of amount of mother plant.

Apolitical Graft

My foray into “totipotencing” plants today required pretty much nothing more than pruning shears. I was cutting scion wood, which are stems for grafting onto growing plants. In this case, the growing plants — the rootstocks — provide roots to the clone; the completed plant, from the graft upwards, is the clone, in this case various varieties of pears.

Watersprouts on old apple tree

In the past, I’ve done a “Henry IVth” on pear trees whose fruits were not up to snuff, then grafted a more desirable scion on to the decapitated trees. Today’s scions are for grafting onto one-year-old pear seedlings, to make new pear trees. (Not that I need that many pear trees. The grafting will be done by participants at a couple of grafting workshops I’ll be holding this spring. Stay tuned to my website for when, where, and other details.)
Grafts are most successful with young scions — one-year-old stems, those that grew last season. They come in various sizes, depending on their vigor; pencil-thick is about right. I cut them into foot-long lengths. Watersprouts, those vigorous, vertical branches often appearing in the upper parts of a tree, are good for scionwood, and most, anyway, should be removed.

Pear scions

The odds for success are also increased if grafting takes place with dormant scions grafted on rootstocks that are either dormant or awakening. That’s why I collected scions today; they’re still dormant, but not for long, outdoors.
I’ll keep those scions dormant with cold, in the refrigerator or my mudroom (north side of the house, tile floor over concrete).
Drying out would spell death to the scions, as it would to any living plant or plant part. They need to be kept hydrated, but not in so moist an environment as to cause rotting. So I store them in a plastic bag, around which I wrap a moist towel, and then put the towel-wrapped bag into another plastic bag, well-sealed.

I Was Wrong About Arnold

I was wrong. Back in December, I wrote, “My Arnold’s Promise witchhazel usually flowers in March. This year’s October flowering means no flowers this coming spring.” Well, it’s March 1st as I write this, and Arnold’s Promise is showered with strappy, yellow blossoms.

Witchhazel’s winter flowers and remains of fall flowers

Evidently, not all flower buds slated to open this month opened prematurely, last October. Some did as they are supposed to do: waited. Why? Good question. Looking at the shrub, a location effect does not seem to come into play. Late winter blossoms seem randomly distributed rather than concentrated on older, younger, lower, higher, southern, or northern stems.
With no explanation coming to mind (yet!), I’ll just relax and enjoy the unexpected show.
