Timing Gone Awry But Composting On Schedule

November 3, 2017/4 Comments/in Gardening, Planning, Soil, Vegetables/by Lee Reich

Time Change

Much of gardening is about timing — getting tomato plants in the ground early enough for a timely harvest, but not so early that transplants are killed by a late frost; checking that there’s enough time following harvest of early corn for a late planting of turnips, etc. So, when I began gardening, I read a lot and took lots of notes on what worked here in Zone 5, and eventually compiled everything into a neat table of when to do what.

I figured, with that table, that I was all set and would no longer have to respond to a gut impulse to plant peas during a freak warm spell in late February. Or to keep reading seed packets and counting back days to maturity to compute if there was still time, or it was too early, to plant a late season crop of endive.

Not so! In the few years I have gardened, which, though decades, is infinitesimal in geologic time, the climate has changed enough for me to have to shift those dates I so carefully figured out. No longer must I wait until the end of May to sow okra, squash, and other vegetables; the ground warms sufficiently to induce them to sprout a couple of weeks earlier now. No longer does a hard freeze strike tomato vines dead by the end of September. As I write, it’s the end of October and last night the first frost — a light frost — crept into the garden; later today, though, I’ll be picking ripe Sungold tomatoes.

Some perennial plants that, in the past, usually died back to the ground each winter, then resprouted in spring, no longer die back. Yellow groove bamboo, for instance. Nowadays their leaves stay green through most winters, which translates to taller and thicker canes. Crocosmia corms would hardly flower in years past; nowadays I don’t bother to dig up the corms, which flower and spread prolifically.

Taking Care of My Little Pets

Some things, gardenwise, are timeless or, at least, not time sensitive. The changing daylength throughout the year, for instance. And composting. Compost bins

Although I feed my compost “pets,” that is, all the micro- and macroorganisms living and working the compost pile, all season long, this time of years those pets have a veritable banquet. In addition to the usual trimmings and scraps from the kitchen, beds are being cleared of corn, beans, okra, cucumbers, and all those other summer vegetables that are petering out.

I’m also having a lot of fun weeding. Yes, fun. Yes, weeding. (You might wonder why the author of the book Weedless Gardening has weeds. I grow a lot of fruit trees, shrubs, and vines, and some flowers, in addition to vegetables. I have too much garden. I can’t help myself. But everything is Weed-less.)

The ground has enough moisture in it so weeds are easily pulled. On my knees, I pull at a clump of Creeping Charlie, and creeping vines extending for 2 feet in all directions move up and out of the ground. I grab a clump of quackgrass and, if I lift carefully, a couple of feet of its creeping rhizome that attempts to extend its reach releases from the ground.

All this goes into the compost pile along with some horse manure and bedding, some hay I scythe from my field, and occasional sprinklings of soil and dolomitic limestone. As I layer these materials, I pay attention to their ratios of carbon and nitrogen, the two main feedstuffs of my compost pets. Old plants are relatively richer in carbon, young ones in nitrogen. Manure is rich in nitrogen, the bedding (wood shavings, which is old plants) in carbon. Too much carbon, and decomposition is sluggish. Too much nitrogen, and the pile gets smelly.

I also consider how fast ingredients might decompose. Wood shavings, for instance, are high in lignin, which slows decomposition no matter what their ratio of carbon to nitrogen.

The Little Guys Are (Usually) Thirsty

Two things that often slow composting are heat loss and insufficient moisture. Small compost piles lose too much heat; the critical mass for good heat retention is about a cubic yard. The bins into which I pile ingredients insulate the edges to further retain heat.

A lot of water is needed to seep way down into a pile. Rather than keep trying my patience holding a hose wand, a couple of years ago I purchased a small sprinkler and attached it to some plastic pipe so it fit neatly on top of my compost pile. A pressure regulator (usually used for drip irrigation systems) keeps incoming pressure constant so I could adjust an inline valve to make the spray consistently reach just to the edge of the pile. Twenty to thirty minutes gives my compost pets a good drink. Compost sprinkler

A long-stemmed compost thermometer is my final check that all is well. The piles typically reach 150°F. Compost piles don’t need to get that hot; more time composting also does the trick. Any pile of organic materials eventually becomes compost..

Grapes And Onions

October 26, 2017/5 Comments/in Fruit, Gardening, Pests, Vegetables/by Lee Reich

So Many Choices, In Grapes

With over 5,000 varieties of grapes from which to choose, how can anyone decide which to grow? For better or worse, that choice is naturally limited by climate and pests in each part of the country. Here in the northeast, major limitations are humid summers that spread indigenous disease and frigid winter temperatures.

There’s still plenty of grape varieties from which to choose, which I’ve done over the years, weeding out varieties that would succumb to cold or disease. My varietal possibilities are further limited by my low lying land close to acres upon acres of forest. Cold, moisture-laden air sinks into this low spot, and the abundance of wild grapes clambering up forest trees provide a nearby reservoir of insects and disease spores.

With all that, I want to grow varieties that taste good to me (fresh, not for wine). I have dairy farmer-cum-grape breeder Elmer Swenson to thank for many of the delectable varieties that bear well here, and that I would recommend to others. His Somerset Seedless was ripe back in August, as was his seeded Swenson Red. Right now, the seeded variety Brianna — one of my favorites for flavor — is just finishing, just after Edelweiss and Lorelei.

Swenson Red Grape

Edelweiss has the strong, “foxy” flavor characteristic of American-type grapes, so is not for everyone. That flavor is most familiar in the well-known variety Concord, originated by Ephraim Bull in Concord Massachusetts over 150 years ago. I finally got around to planting a Concord vine a few years ago, and finally decided this year, despite my affinity for grape foxiness, that I didn’t like Concord’s flavor.

Edelweiss grape

Mr. Swenson isn’t responsible for all my favorite grapes. There’s Alden, with a nice, meaty texture to go with its distinctive flavor. And two excellent, seedless grapes: Glenora and Vanessa. I’m going to rip Concord out of the ground, as well as Cayuga White, which also didn’t make the flavor cut, and Mars, which gets too much disease, and replace them with additional vines of Glenora and Vanessa. The jury is still out on Wapanuka, Reliance, and NY Muscat.

Concord grape

All my “keeper” varieties bear reasonably well and are bursting with distinctive, delicious flavors such that I cannot, even when grape season has passed, bring myself to eat the relatively flavorless varieties generally offered from supermarket shelves.

Rotting Onions

How are your onions holding up? Mine, not so well. I knew that the giant Ailsa Craig onions weren’t keepers. But they shouldn’t be already turning soft and smelly.

Some sleuthing uncovered the culprits: the bacteria, Pantoea agglomerans and/or its cousin P. ananatis, both of which can be lumped together in the affliction called “center rot.” The symptom is rotting of one of the rings (scales) somewhere between the center and the outside of a bulb. Onion center rot

Most plant diseases are caused by fungi rather than bacteria, and fungal diseases are generally easier to control. Even pesticide sprays are not very effective against either onion pathogen. Warm, moist conditions are what have allowed the Pantoea cousins to thrive this year.

Which is not to say that I plan to sit back and watch my onions spoil in future years, or give up growing onions. I already rotate my onion plantings, which would have been my first plan of attack. Although now that I think of it, though, I do often stick a few of various types of onions and excess seedlings here and there around the garden. No more.

The environment can be made less friendly to the bacterium. Mulching the plants would keep the soil cooler. Especially a few weeks before harvest, any watering should cease. Nitrogen fertilization also needs reining in, which would be hard to do in my garden because I fertilize only with compost. Perhaps mulching would cool the soil enough to slow the compost’s mineralization of soluble nitrogen that plants could absorb.

Onion varieties vary in their susceptibility to center rot. Generally, it is the sweet, European type varieties, such as Sweet Spanish, Candy, and Ailsa Craig, that are most susceptible.

Harvest can play a role also. Too early, before leaves have sufficiently dried and flopped down, and the bacteria might be able to edge its way into the bulb. I normally harvest when tops flop down and bulbs easily roll out of the soil (good), then leave them in place to cure in the sun (bad). Next year, I’ll roll them out of the soil and then move them to a shaded, airy place to cure. Or lay them out in the garden so each onion’s leaves covers its neighboring onion’s bulb.

All these measures are worthwhile even if your onions have always looked fine. Center rot bacteria are pretty much ubiquitous, just waiting for good enough conditions to ruin your (and my) onions.

How Pesky And Interesting

September 29, 2017/0 Comments/in Fruit, Gardening, Pests, Vegetables/by Lee Reich

Snowflakes? No.

Gardening never ceases to be interesting, even if the current object of interest is a pest. Not just any pest, but a NEW pest! And not just for me.

I was alerted to this pest when pulling a few weeds near my Brussels sprouts plants. Brushing against their leaves brought a cloud of what looked like fine snowflakes. They were, in fact, whiteflies, tiny (1.5 mm) fluttering insects, immediately recognizable to me from their common occurrence on houseplants.

Cabbage whitefly

Whiteflies rarely show up on outdoor plants; in my experience, never. Easy enough to discover on the web, my whiteflies are appropriately named cabbage whiteflies (Aleyrodes protella). This native of Europe first turned up in the U.S. in 1993, but is rare in the Hudson Valley. It’s fond of all cabbages relatives, with a preference for kale. Not in my garden, though; kale, sharing the bed with the Brussels sprouts, is hardly attacked.

The attack seems mild, most evident, besides the snow clouds, as some black, sooty mold on the plants. Sooty mold is a fungus that feeds on the sweet exudate the insect drips on the plant. It’s only on the surface of the leaf so is harmless unless it becomes so dense that the leaf is shaded.

Cabbage whitefly isn’t easily controlled with chemical pesticides. I’m not worried, though, because the level of damage doesn’t warrant my lifting a finger against them.

If some control is needed before the season ends, sprays of either insecticidal soap or horticultural oils are effective — and won’t disrupt the whiteflies’ natural insect and fungal enemies, of which there are plenty. Cleaning up the bed at the end of the season also helps, for next year. Yellow-colored cards coated with something sticky, like Tangletrap, also could offer some control. For now, though, I’m just watching them flit about each time I draw near.

Peach Harvest

The peach crop got harvested a few days ago, all two of them. The tree is small, but not that small; it could have supported a couple of gallons of peaches.

This was a good season for peaches. Unfortunately, my farmden is not a good site for fruit. Insect pests can move in from the woods only 50 feet from the trees, and the low lying ground acts like a basin into which cold air can collect. That cold air brings late frosts (not this year), and moister air in which fungal diseases fester. Those are my excuses for my two-peach harvest.

On the other hand, my investment in the tree has been minimal. The tree grew from a peach pit. Sow an apple seed and the tree might take 10 years before it yields its first fruit. And then, after that long wait, the chance of that fruit tasting good is only about one in 10,000. Sprouting peach pit

Sow a peach seed, and the tree might bear in 4 years. The fruit on that tree is likely to taste quite good, perhaps great. Peaches are self-pollinating, so there’s no foreign genes introduced into the resulting pit. Not so for apples, which don’t bear fruit unless pollinated by a different variety.

My peaches, by the way, tasted great. And, with gracefully drooping leaves that retain their shiny green color all season long, the tree is very attractive. I am hoping for a larger crop next year.

Ladybugs to the Rescue

Aha. Checked back with the whiteflies on the Brussels sprouts, and what do I see? Some ladybugs dining, moving up and down the leaves. The young larvae are likewise at work along with their parents. Ladybug on cabbage leaf

(The “lady” in ladybug is, by the way, the virgin Mary. The German word for them, Marienkafer, translates also as Marybeetle.)

Among the many species of ladybug, all in the family Coccinellidae, are some that specialize in devouring mites, others specialize in mildews, still others on mealybugs (I mentioned last week purchasing and using them for fig mealybugs), some for scale insects, and so on. Some members of the family feed on plants: squash beetles and Mexican bean beetles, for instance.

I don’t know which species of ladybug is at work on my Brussels sprouts, but I’m happy to have them.

It Ain’t Over ‘Til It’s Over, and Pears

September 21, 2017/0 Comments/in Fruit, Gardening, Planning, Vegetables/by Lee Reich

Whoosh!

Whew! How quickly this growing season seems to have scooted by. I am putting the last plants of the season into the vegetable garden today. These were transplants of Shuko and Prize Choy bok choy, and Blue napa cabbage. I’m eyeing some lettuce transplants, and if I decide that they’re sufficiently large to transplant, they’ll share a bed with the cabbages. Chinese cabbage transplants

Reconsidering, the end of the gardening season isn’t really drawing nigh. The cabbages won’t be large enough to make a real contribution to a stir fry or a batch of kim chi for at least another month. And then, with cool weather and shorter days slowing growth, the plants will just sit there in the garden, doing fine, patiently awaiting harvest.

Other plants awaiting harvest into autumn from plantings over the past few weeks are Hakurei turnips, crunchy, sweet, and spicy fresh in salads, daikon and Watermelon radishes, for salads or kim chi, and, also for salads, lettuce, spinach, arugula, and mustard greens. The last salad stuff will be endive, sown back in early July, and transplanted in early August in a bed previously home to the first planting of bush beans.

The season’s various plantings mesh together nicely. Those bok choy and napa cabbages went into a bed just cleared from the first planting of sweet corn. The bed previously planted with of lettuce, arugula, and spinach seed followed on the heels of onions sown indoors in February, transplanted into the bed in May, and harvested a few weeks ago.

A Whole New Garden, Now

In addition to good timing, the autumn garden — which is like having a whole other garden, except it’s in the same place as the summer garden — demands good soil. That soil has to support this whole other wave of plants.

Through summer, I looked upon any weeds I encountered as potential factories for making more weeds, via spreading seeds and/or roots. Left alone, that weed and its progeny would rob food and water meant for my cabbages and lettuces, and shade my plants into submission.

With that in mind, when I cleared the beds of spent corn or bean plants, I pulled out every weed in addition to the spent vegetable plants. I tried to get roots and all for each weed, which isn’t that difficult if you keep up weeding all summer.

After clearing a bed of weeds and vegetable plants, down went a carpet of compost. Spreading compost on bed A one to two inches deep layer smothers most weeds sprouting from seeds as well as provides nourishment for multiple waves of vegetable plants — for a whole year! (Also provides food and habitat for beneficial soil organisms, protects the surface from washing, and increases the soil’s ability to hold on to both air and moisture.)

So the season hasn’t scooted by; the autumn season is just beginning. There’s still some room for reflecting on the season up to this point. Most notable has been this year’s pear crop.

Pears: Easy To Grow, Hard To Harvest (Correctly)

Among the common tree fruits, pears are the easiest to grow. They’re a bit slow to come into production but are often free of significant pest problems. They’re also pretty trees, all season long, especially the Asian pears.

It’s not all smooth sailing from planting to flowering to harvest to eating for European pears, which includes Bartlett, Bosc, Anjou, and other pears with which most people are most familiar. The problem is knowing when to harvest them. Pears ripen from the inside out, so need to be harvested when mature (whenever that is), then ripened in a (preferably cool) room indoors. Left hanging on the tree too long, and the fruit tastes sleepy, at best, or has turned mushy; harvested too soon and the fruit never loses a grassy flavor. (Asian pears are easy to harvest. When they taste good right off the tree, they’re ripe and ready.)

Frederick Clapp pear tree

Appearance of the fruit, calendar date, and ease of separation from the stem when lifted with a twist are all indicators of ripeness. I’m finding that few fruits dropping from a tree are a good sign that it’s time, or almost time, to harvest.

Pears, A Book

As luck would have it, a beautiful new book, The Book of Pears, by Joan Morgan, arrived in the mail just as pear harvest was beginning (with the variety of Harrow Delight). Replete with old and new illustrations depicting the history of pear cultivation, a large portion of the book offers intimate descriptions and history of many varieties. Beurrée d’Amanlis, for instance, which I grow, originated in a small village in Brittany, but became popular after 1826, when Louis Noisette, a Paris nurseryman, received some fruit from his son, director of the Nantes Botanic Garden.

The book devotes a little space to growing and cooking the fruit. I, of course, immediately looked to see what Ms. Morgan has to say about harvest: “ . . . the next challenge is when to harvest the crop . . . Once they begin to drop from the tree it is time to harvest . . . Experience with your own trees will tell you when to pick.” How true. I’ve grown the variety Magness longest, and usually can pick them to ripen off the tree to perfection. And perfection for Magness means biting into one of the best tasting of all pears.

Picked At Peak Of Perfection

August 31, 2017/7 Comments/in Fruit, Gardening, Vegetables/by Lee Reich

Tomatoes Vs. Sweet Corn

Some gardeners sit tapping their fingers waiting for the first tomato of the season to finally ripen. I don’t. I’m waiting to sink my teeth into my first-picked ear of sweet corn.

Not that my tomatoes don’t taste really good, but they’re also good all winter dried or canned, as is or as sauce. Or just frozen.

An ear of sweet corn, though, captures the essence of summer. Not just for flavor and texture. It’s the whole ritual of peeling back the husks and snapping them off at their bases, brushing away the silk before steaming the ears, and then, holding an ear at each end, biting off kernels from one end to the other like an old fashioned typewriter carriage. (An image perhaps unknown to readers below a certain age.)

An art to harvesting corn at the just-ripe stage, and anxiousness for that first taste, make harvesting, especially early in the season rather tenuous. I do early planning for that first taste by counting the days-to-maturity from when I planted. Problem is that the days listed on seed packets vary: One seed company lists days to maturity for Golden Bantam, the variety I grow, at 75 days; another lists it at 85 days; another at 78 days; and yet another, more realistically, at 70 to 85 days. It depends on where the variety is grown and how the season develops.

The real countdown begins when tassels first appear atop the stalks. Harvest will be about 3 weeks hence.

Then it’s time to keep an eye out for drying tassels at the end of an ear. Once that happens, the time is near. That right moment is critical because harvested too soon, and the kernels have little taste. And this is among those fruits — yes, corn is a fruit, botanically — that will not ripen at all following harvest. Harvested too late, and the kernels are tough and starchy.

That exact right moment for harvest is when the ear feels “full” when grasped in my hand and a kernel on the peeled-back husk, with the ear still attached to the stalk, oozes a milky fluid when pressed with the thumbnail. If all these systems are go, it’s time to snap off the ear and whisk it to the waiting pot of steaming water. Corn, testing for ripeness
Golden Bantam is a non-hybrid variety. Like other non-hybrids, a planting does not ripen all at once, which is not a good commercial characteristic. It’s fine for me, though, because between staggered plantings and a wide window for harvest for each planting, I intend to be eating Golden Bantam corn, a favorite for many gardeners since its introduction in 1906, for weeks to come.

Watermelon, Are You Ripe

Besides the first harvest of Golden Bantam, which I’ll be enjoying by the time you read this, I’m also eagerly awaiting the first harvest of watermelon, which, according to days-to-maturity listed on the seed packet, 65-75 days, I should have already been eating. (I sowed seeds indoors in pots in mid-May but it’s been a relatively cool growing season.)

While I’m confident in harvesting sweet corn at just the right moment, not so for harvesting watermelon, another fruit that will not ripen at all once harvested. Yes, I know all the published indicators of ripeness: drying up of the tendril closest where the fruit is attached to the vine; a dull thud, rather than a tighter, ringing or hollow sound, when rapped with my knuckles; and a yellow or cream-color of the fruit where it rests against the ground, and a toughening of the skin there, enough to resist indentation with a thumbnail. (The thumbnail is evidently a useful harvest tool.)

A ripe watermelon?

Still, I’m not confident about harvesting watermelons on time, and not even just the first ones to ripen. The trial and tribulation is worth it. I hope to be harvesting and eating ripe watermelon also by the time you read this. (Update: I did and it was.)

Tomatoes, You Are Ripe

In contrast to harvesting Golden Bantam corn and watermelon (I grow the variety Blacktail Mountain), tomatoes are cinch to harvest. Except for some green-ripe varieties, which I don’t grow, tomatoes turn their characteristic shade of red when ripe.

Tomatoes can even be harvested underripe to ripen off the vine. Research has shown that when a tomato is about half green and half pinkish-red on the vine, a layer of cells form across the stem of the tomato sealing it off from the main vine. Then nothing that can move from the plant into the fruit, so the fruit can ripen to perfection. Ripe tomatoes

I came across some older research (J. Amer. Hort. Soc. 102:724-731. 1977) showing that the best-tasting tomatoes are those thoroughly vine-ripened. Duh. I knew that, and will harvest only vine-ripened tomatoes.

Making Sense

Lilies, More Than Just Pretty

I’m triply thankful for the lily stems in the vase in the kitchen.

First, for their beauty. The large, lily-white (of course) petals flare out into trumpets, from whose frilly throats poke groups of rust-red anthers and single tear-capped stigmas. The petals spread about 8 inches wide from one side to the other, and the single stalk I plunked into the vase sports six of them! Lilies in vase

Second, I’m thankful for the lilies’ fragrance. The heady, sweet fragrance fills the whole room.

And third, I’m thankful that the plants, cut from outdoors where they share a bed with staked Sungold tomato plants, are alive. They’ve been threatened by a relatively new pest, the lily leaf beetle (Lilioceris lilii). This European pest made its North American debut in Montreal in 1945, and its debut on my farmden in 2015.

Lily leaf beetle can be controlled by sprays, even organic ones such as Neem or spinosad. But I’m not keen on spraying anything on plants rubbing elbows with edibles, in this case my Sungold tomatoes.
The beetles’ bright red color makes them easy to spot, at which point they can be crushed. Battling the beetle mano a mano is a viable control for a backyard planting. This was my approach a couple years ago. With other garden distractions and many crown imperial (Fritillaria) plants, which also are attacked by the beetle, I abandoned any efforts to control the beetle.

Yes, I saw some beetles on the lilies this season; yes, the plants are still doing well. Plants can tolerate a certain amount of pest damage and still do fine.

Play It Again Sam

My awesome lilies aren’t just any old lilies. They’re true lilies (Lilium species), not daylilies (Hemerocallis species). Once we’ve narrowed down “lily” to the genus Lilium, there are about 100 species within that genus from which to choose.

My lily is one of many varieties of Asiatic hybrid lilies. Its name: Casa Blanca. I highly recommend growing it.

Casablanca lily in the garden

Popeye’s Delight, Later

With eyes and nose taken care of, let’s move on to another of the senses, taste. I’d like some spinach. But I can’t have it — yet. I can plant it very soon, though, and then in a month or so I can be eating it.

So why didn’t I plant it a month ago so I could be eating it now? The reason is that spinach is a long day plant, which flowers (aka “goes to seed”) during summer’s long days. Planted a month ago, even two months ago, and after making a rosette of a few leaves the plant would pump its energy into flowers and seeds. Besides yielding a paltry harvest of leaves, that whole “going to seed” thing also ruins the flavor of the leaves.

Actually, it isn’t long days that make spinach gustatorily morph from Dr. Jekyll to Mr. Hyde; it’s short nights. (Photoperiodism, the name for this response, was originally though to be the response to daylength; calling it a response to “daylength” stuck even after it was discovered that the response was to the length of the the night.) Beets, gladiolas, lettuce, and radishes are also “long day plants.”

Photoperiod doesn’t work alone in prodding plants to grow or flower. Temperature, either before germination or while the plants are growing, also figures in, as does light intensity and soil moisture. Spinach usually flowers when days are 14 or more hours long (more correctly, short nights that are 10 or less hours long), but will also do so following 8 hour days (16 hour nights) if the seeds are chilled.

Nights are now just over 10 hours long so I can plant spinach. While the plants are growing, cooler temperatures, which are coming this way, and adequate water, which my plants will get thanks to drip irrigation, also factor in to keep spinach from going to seed. So the spinach that I sow today will put all its energy into growing large and tasty leaves.

Peas, Please

A taste of peas would also be nice. The spring harvest was good. Still, some gardeners successfully plant peas in summer for an autumn harvest. Not me. Peas in pod

Daylength isn’t what messes up late sown peas, for me, at least. Heat is. Peas languish during hot weather, common through August and even lingering into early autumn. So the peas grow poorly, and if they do weather the hot weather, they are apt to be struck down by the first frost of autumn.

I’ve heard that Wando is a pea variety that can take some heat. I haven’t tried for an autumn harvest for many, many years. With climate change, perhaps autumn peas are worth another try.

Savin’ Seeds, Killin’ Weeds

August 3, 2017/3 Comments/in Fruit, Gardening, Pests, Vegetables/by Lee Reich

Bolting Plants

Last week I was admiring a vegetable garden where just about every lettuce plant was reaching skyward, with flower buds about to cap the tops of the spires. Isn’t that the wrong way to grow lettuce?

Bolting lettuce plants Lettuce that flowers — “goes to seed” — becomes bitter and tough. In my own garden, I aspire to have no lettuce spires by sowing lettuce seeds every couple of weeks for a regular harvest of mild-flavored, succulent leaves or heads. The plants don’t have time to bolt.

Those bolting lettuces I was admiring were in a garden in Iowa, one of the gardens at the Seed Savers Exchange (www.seedsavers.org), an organization that every gardener should know about and a garden that I should have not waited so long to visit. The mission of Seed Savers Exchange is to save and preserve heirloom seeds, which are varieties that have been passed on down among generations of farmers and gardeners. Taste some heirloom tomatoes and it’s understandable why these varieties have been saved and passed on. Belgian Giant tomato may not have the smooth, round shape of a modern Big Boy tomato, but this heirloom is well worth growing for its complex, sweet-tart flavor.

One way that Seed Savers fulfills their mission is by growing and saving many varieties of seed. Hence the bolting lettuces I saw there. Some varieties of vegetables, such as most squashes, tomatoes, and cucumbers, spread their pollen too freely. To keep these varieties seed “true,” contamination from foreign pollen is prevented by growing all plants of a particular variety in fine-mesh, insect-proof enclosures. Seed growing at Seedsavers Netted enclosure to prevent cross-pollination

The Seed Saver mission is also fulfilled by so-called “participatory preservation.” An over 13,000 member network of gardeners grow seeds and share them — to the tune of over 23,000 varieties — through an online seed exchange. Anyone can browse the listings but only members can request the seeds.

Not that non-members don’t have access to any of these seeds. Every year, Seed Savers Exchange publishes a seed catalog, from which anyone can order seeds. The names of the old varieties themselves make some of the seeds irresistible: Tolli’s Sweet Italia pepper (better name than flavor), Green Arrow Pea (excellent flavor and high yielding), Jelly Melon cucumber (very interesting name and appearance, but I have yet to try it).

What To Do With Weeds

Ten days absence from my garden, with warm, sunny weather interspersed with rainy days adding up to two inches of rainfall, wrought big changes. Sweet corn and polenta corn reached well over 5 feet in height, flopping stems of staked tomatoes were in desperate need of tying, blueberry stems bowed down with their weight of plump, ripe berries, and . . . weeds were abundant.

Ninety percent of the weeds were Canadian thistle, crabgrass, purslane, pigweed, common yellow wood sorrel (Oxalis sricta) and — my worst weed — creeping woodsorrel (Oxalis corniculata). I’m jerking each thistle out with a gloved hand. Yes, roots left in the ground will resprout. I’ll just keep jerking them out until they expend all their stored fuel and before new shoots can start pumping new fuel down to the roots, and the plants will die. I poke my hori-hori knife right at the roots of crabgrass and toss the severed tops into the compost bucket.

Yellow wood sorrel is easy, and sort of fun, to remove; pull the plant and the whole thing comes out easily. Creeping woodsorrel is another story: With brittle stems that creep just below ground level and dirt-colored leaves, it’s hard to see and hard to remove. Most effective is a spray of household vinegar, repeated each time new stems grow.

The way to remove purslane and pigweed is to harvest it — yes, for eating. Unfortunately, I don’t like purslane, so I weed it. But pigweed is a delicious cooked green. I wish I had more of this weed; it cooks down a lot and the harvest was over after two dinners.

Bye, Bye Black Currants

Belaruskaja black currants

I mourn the passing — okay, “mourn” is a bit too strong — of fresh blackcurrants. The harvest was bountiful and long lasting, but now is over. Over twenty quarts of them are in the freezer but those are for eating through the winter.

THE GOOD OL’ DAYS

June 28, 2017/1 Comment/in Fruit, Gardening, Pests, Planning, Vegetables/by Lee Reich

Corn Made Even easier

I can understand why corn was so popular a crop early on in the settlement of our country by Europeans. Sure, it tastes good popped, ground and cooked, and, while immature, fresh from the cob. Mostly, though, corn was easy to grow in the rough soil left from recently cleared forest.

Most of my corn grows in my two vegetable gardens where the soil is crumbly and weed-free, watered gently by drip irrigation, and nourished annually with an inch depth of compost.

Highly cultivated sweet corn

The south garden is home, every year, to a couple of beds (about 60 square feet) of popcorn, and the north garden to 4 beds (about 215 square feet) of sweet corn. Those two gardens provide us with all the sweet corn and popcorn we eat for a year.

Separate gardens are needed because if sweet and popcorn cross-pollinate, the sweet corn will be less sweet and the popcorn won’t pop as well.

I also grow polenta corn, an heirloom Italian variety called Otto File. But I only have two vegetable gardens. So this corn goes out in the field into the weedy soil between my dwarf apple trees. Conditions there aren’t as rough as cornfields wrought from forests in colonial times, but out there the corn must deal with weeds, grasses, rabbits, and drink only water that falls from the sky.

I did not use colonial methods to ready the soil for planting. Instead, I mowed all vegetation to the ground, and covered the planting areas, 2 beds each about 3 feet wide for a total of about 100 square feet of planting, with gray resin paper. (Sometimes called building paper, gray resin paper is used in construction, usually as underlayment under flooring and siding.) I topped the paper with an inch or so of compost, then made two rows in each bed, in each row poking holes 2 feet apart into each of which I dropped 6 Otto File seeds followed by a sprinkling of water.

The seedlings are up and looking strong, so I thinned them out to 3 or 4 plants per hole, pulling out a few weeds as I thinned. I’ll weed one or two more times and then leave the plants to themselves. Weeds will grow, but the then-tall corn plants should shade some into submission and hold their own against the more aggressive ones. Otto File planted in field

For authenticity, yes, I could have buried some fish in the ground at each planting hole. But that would be more work, and I’m interested in production with minimal effort from that planting. Each year those beds have provided a year’s supply of polenta corn.

Apple Threats

Apple trees flanking the Otto File beds are loaded with a hopeful crop of cherry-sized fruits. The dreaded plum curculio, which is as happy to ruin a crop of apples, peaches, nectarines, or cherries as well as plums, should have ceased their egg-laying by now, and burrowed into the soil to prepare for next year’s onslaught. (Surround® is an organically approved spray of specially formulated kaolin clay that controls curculios.)

Just because the nascent fruits have come along this far does not mean I’m home free. Apple maggot reliably makes its appearance just as the curculios vanish. This pest doesn’t usually make the fruit drop, as do curculios, but it riddles the fruit with so many tunnels that you can’t even eat around them.

Maggot & curculio scars

Fortunately, non-chemical control of apple maggot is easy. In the 1980s, Dr. Ron Prokopy, at the University of Massachusetts, discovered that Ms. Maggot was attracted to the reddest apples, so he tried hanging croquet balls painted Tartarian Red and coated with forever-sticky Tangletrap® in apple trees. Maggots tried to lay eggs in the ersartz apples, where they expired, their mission unfulfilled. The spheres offer as good control as do chemical sprays.

In the last few years, I’ve used Tangletrap® coated, real Red Delicious apples as traps. They are very red and very apple-like. Hung in the branches, one per dwarf apple tree, they last almost the whole season and, when the season ends, can be composted rather than scraped clean for use the following year. Red Delicious maggot trap

Apple maggot isn’t the only remaining threat to my apples. There’s also the codling moth (the classic worm in the apple), apple scab (that’s what it looks like), and various summer rots.

Once Upon A Time

Oh, for the good ol’ days when the grass was greener, the corn was sweeter, and apple trees took care of themselves. Mostly, the good ol’ days weren’t the various “-ers.” But one exception was the apple maggot. Two hundred years ago, Ms. Maggots didn’t look twice at apples. This native insect was happy to attack our native hawthorns, which are related to apples.

When apples were introduced to this part of the world, some apple maggot flies tried them out. Over time, some began to favor apples over hawthorns, so much so that the maggots evolved into two tribes, one favoring hawthorn and the other apples. Oh well.

PERENNIAL VEGGIES AND A DEAD AVOCADO

June 15, 2017/11 Comments/in Fruit, Gardening, Vegetables/by Lee Reich

King Henry Was, And Is, Good

The good king has gone to seed. Good King Henry, that is. A plant. But no matter about that going to seed. The leaves still taste good, steamed or boiled just like spinach.

The taste similarity with spinach isn’t surprising because both plants are in the same botanical family, the Chenopodiaceae, or, more recently, the Amaranthaceae. Spinach and Good King Henry didn’t change families; their family was just taken in by, and made into a subfamily of, the Amaranthaceae.

Whatever its name — and it’s also paraded under such common names as poor man’s asparagus and Lincolnshire spinach — Good King Henry is a vegetable that’s been eaten for hundreds of years, except hardly ever nowadays. While spinach, beet, and some of its other kin have been improved by breeding and selection over the years, Good King Henry was neglected.

But the Good King, besides having good flavor, has a few things going for it lacking in spinach. It’s a perennial plant, it’s edible all season long, and it has no pests problems worth mentioning. This Mediterranean native made its way to my garden over 20 years ago, from seed I purchased and sowed. I haven’t had to replant it since then.

Which brings me to one possible downside of Good King Henry: It keeps trying to spread beyond the far corner of the garden where I originally planted it. Every spring I yank out errant plants, and eat them.

One of my favorite things about Good King Henry is its species name, bonus-henricus, making its whole botanical name Chenopodium bonus-henricus.

Another Perennial Oldie

Another perennial vegetable that I’ve enjoyed this spring is seakale (Crambe maritima), a relative of cabbage, broccoli, and kale. This also is an old-timey vegetable, one whose popularity peaked in the 18th century; Thomas Jefferson was a fan.

The origin of the name may trace to the leaves (kale-like) being pickled to bring aboard ships (the “sea” part of the name) to prevent scurvy.

Seakale, though perennial, does not spread. I started my plants from seed a few years ago, which is tricky only because the seeds have a low germination percentage. I’ve seen a few seedlings pop up a foot or so from the mother plant, which I welcome as an easy way to multiply my holdings. Seakale, blanched

Seakale tastes very good either cooked or raw, something like a mild cabbage with a refreshing touch of bitterness. Either way, blanching is needed to make it tasty, and that entails nothing more than covering it for a couple weeks or so, more or less depending on the weather (more warmth, less time), to keep out light and make the shoots more mild and tender. I invert a clay flowerpot over the whole plant, with a stone or saucer over the drainage hole to keep light from wending its way in. Like asparagus, new leaves eventually need to be set free to bask in the sun to fuel the roots for the next year’s early shoots.

One more plus for seakale is that the plant is a beauty, so much so that it’s sometimes planted as an ornamental. The wavy, pale bluish green leaves have a silvery pallor reminiscent of the British seascape to which they are native. Later in the season, a seafoam of white blossoms rises from the whorl of leaves.

I Give Up

Now for an about face, from European plants enjoying cool weather and sometimes dry conditions, to a tropical American plant. Awhile back I wrote about my efforts to grow avocados here in New York’s Hudson Valley. Not on a large scale; just one or two plants from which I could harvest a few fruits of some special variety.

I grew two plants from seeds I saved from locally purchased avocado fruits, and grafted onto those seedlings the stems of two varieties a gardening buddy sent up from Florida. Ungrafted, the seedling plants would bear fruit of unknown quality, if they bore at all. Grafted plants would give me improved, named varieties that would bear quickly. Avocado grafts

I failed. Only one graft took, yet two varieties are needed for fruiting. As expected, the grafted stem on the successfully grafted plant flowered within a year of grafting. For days I tried to get the pollen from the male to pollinate the female parts of the flower — to no avail. And then, for some reason, the grafted stem started to darken and turn black, and died back. Avocado with dead graft

I give up on trying to grow an indoor-outdoor avocado plant — for fruit — in a pot.

AWESOME BLOSSOMS & RATIONALITY

June 1, 2017/1 Comment/in Flowers, Gardening, Planning, Vegetables/by Lee Reich

Wow!!

With blossoms spent on forsythias, lilacs, fruit trees, and clove currants, spring’s flamboyant flower show had subsided – or so I thought. Pulling into my driveway, I was pleasantly startled by the profusion of orchid-like blossoms on the Chinese yellowhorn tree (Xanthoceras sorbifolium). And I again let out an audible “Wow” as I stepped onto my terrace, when three fat, red blossoms, each the size of a dinner plate, stared back at me from my tree peony.

Tree peony blossoms

Both plants originate in Asia. Both plants are easy to grow. Both plants have an unfortunate short bloom period, more or less depending on the weather. Fortunately, both plants also are attractive, though more sedately, even after their blossoms fade.

The tree peonies have such a weird growth habit. I had read that they were very slow to grow so was quite pleased, years ago, when each of the branches on my new plant extended its reach more than a foot by the end of its first growing season. Tree peony is a small shrub; at that rate mine would be full size within a very few years. Or so I imagined.

The tree peony still grows that much every year. But every year many stems also die back about a foot, more following cold winters. No matter, though, because every May giant silky, red flowers unfold from the remaining fat buds along the stem.

I originally planted Chinese yellowhorn not for its flowers but for the fruits that follow the flowers. Each fruit is a dry capsule that later in summer starts to split open to reveal within a clutch of shiny, brown, macadamia-sized nuts. Yellowhorn frequently makes it onto permaculture plant lists, with the edible nuts billed as having macadamia-like flavor also. Not true. I’ve tried them raw and roasted. Roasting does change the flavor, but raw or roasted, the flavor is bad. Yellowhorn tree

Still, those blossoms make yellowhorn well worth growing. And after the blossoms fade, this small tree is adorned with shiny, lacy leaves. Much like the tree peony, yellowhorn grows many new stems each year, and many of the stems die back, not necessarily from winter cold but because they’re seemingly deciduous. I tidied the tree up last week by pruning off all the dead stems.

Out With You-All

Today, May 25th, with temperatures around 90 degrees F., I may not be able to restrain myself. It’s hard to imagine that temperatures could still plummet below freezing at least one night sometime in the next week or so. I’ve already ignored that “should” and a few days ago moved houseplants outdoors.

Why the rush? First of all, houseplants enjoy growing outdoors more than growing indoors. Outside, breezes rustling leaves and stems make for stronger, stockier growth and rain showering the leaves washes off a winter’s accumulation of dirt and grime.

After a winter indoors, the plants do need to acclimate to these conditions, which is why they start their outdoor vacation on the terrace on the north side of the house, which blocks wind and, for part of the day, sunlight.

I also urged the plants outdoors because populations of aphid and scale insects were outgrowing the appetites of the ladybugs crawling up and down the stems. Outside, natural predators keep pests in check and, if necessary, I can spritz the plants down to knock off pests and spray soap or summer oil to kill them without worrying about getting spray or oil on windows, walls, or furniture.

The Rush On Sweet Corn

Even tender seeds, such as corn, squash , and beans, can be sown now. The earth has warmed enough for decent germination, and by the time the plants are up, warm weather will have settled in for the season.

Tomorrow I plant sweet corn. Kinky as it sounds, I’m anxious to sink my teeth into a freshly picked ear.
