Future Tense, Present Tense

Past is Present . . . No! . . . Present is Future

Gardening is so much about planning for the future. Dropping seemingly dead, brown specks into a seed flat in spring in anticipation of juicy, red tomatoes in summer is fun and exciting.

But now, in the glory of summer, I don’t particularly like planning, which means thinking forward to the crisp days of autumn that lie ahead. But I must. I know that when that time finally comes, I’ll have had my fill of hot weather. And the cooler weather coupled with shorter days and low-hanging sun will have tomatoes, cucumbers, peppers, and other summer vegetables on the wane. Planning and action now let me have a whole other garden come autumn, a garden notable for its shades of green (from leaves) rather than the reds and yellows (from fruits) of summer’s garden.

I’ll need plants and free space ready for my autumn garden. Some plants are already in place: One bed has been home, since early spring, to kale, which keeps growing as we harvest leaves through spring and summer, and brussels sprouts, from which harvest won’t even begin until early October.

Cabbage plants sown in seed flats in early June are about ready to plant now out in the garden for autumn harvest. Today I sprinkled seeds of endive into mini-furrows in potting soil in a seed flat.Seed flats The endive seedlings will be ready to move out into the garden in 5 or 6 weeks. I’ve also sown more kale seeds to supplement the spring kale for harvest into and perhaps through (depending on the weather) winter.

Early August will be a good time, around here, for planting Watermelon — the Watermelon variety of winter radish, whose innards look like cut watermelon but taste very radish-y. Also turnips, the delicious variety Hakurei.

I’m also sowing lettuce seeds, which I’ve been doing since spring and continue to do every few weeks. They also go into seed flats, ‘GrowEase’ seed starters, from which I can pop out transplants into any spaces that open up here and there around the garden.

Looking for an Opening

So where am I going to plant all those endives, cabbages, winter radishes, and turnips? The autumn garden will also need room for direct sowings of quickly maturing autumn vegetables like arugula, mustard, and lesser known salad “greens” like mâche (corn salad), erba stella (minutina), and claytonia (miner’s lettuce). The garden is packed full of plants now.

Going into August, space will open up for those autumn garden plants. From my first planting in mid-May, I’ll pick the last ripe ear of Golden Bantam sweet corn around mid-August, then have a whole bed available as soon as I clear away the spent stalks. Similarly for the beds of onions, early bush beans, and edamame.

Black Raspberries (Blackcaps) Redux

Enough planning for autumn and beyond. I’m going outside to feast on blueberries, black raspberries, and gooseberries, for me the essence of summer.Black raspberry

Now that I think of it, as soon as the black raspberries finish up, which is very soon, I do have to plan for them also, for late summer and autumn. The varieties I grow — Niwot and Ohio’s Treasure — are unique in being two-crop black raspberries, just like my “fall-bearing” (“everbearing”) raspberries. That is, they bear in early summer on stems that grew last year, just like conventional black raspberries. But — and here is where they are unique — they also bear in late summer and autumn beginning at the tips of new stems that rose from ground level this spring.

Last year’s stems are just finishing fruiting, after which they begin to die. I’ll cut them away to make room for the new stems and to keep the late summer and autumn harvest from these new stems from becoming a thorny nightmare.Black raspberry fruit

Fruit, Again, With Nod To Michael Jackson

Blackcaps Redux, This Season

I took a cue from Michael Jackson today when pruning my black raspberry (a.k.a. blackcap) plants. Not that I had to prune them today, or even this time of year. But I couldn’t stand looking at the tangled mass of thorny canes. And, more importantly, the tangled mass would make harvest, slated to begin in a couple of weeks or so, a bloody nightmare.

(Most blackcaps bear only once a year, in early summer, so tidiness would be the main reason to prune conventional blackcaps now. Pruning would also let remaining canes bathe in more light and air, reducing the threat of diseases. My blackcap plants, though, are the two varieties — Niwot and Ohio’s Treasure — that bear twice a year; hence, my pruning now to make picking the soon-to-ripen second crop less intimidating.)

All blackcaps have perennial roots and biennial canes. Typically, the canes just grow their first year, flower and fruit their second year, then die. Niwot and Ohio’s Treasure differ in bearing on both one-year-old canes and on new canes. I picked the early summer crop from canes that grew last year. And now my mouth is watering as I look forward to the late summer crop, which will be borne on canes that just started growing this season.
Pruned blackcaps
Pruning is straightforward. I started by lopping right to ground level all the canes that bore the early summer crop; they’re dying anyway. Step two is reducing the number of new canes, selectively keeping the fattest and healthiest-looking ones, and lopping all others to ground level. Even then, I reduce their number to the best six of them. That’s it. Easy, as long as the thorns are avoided.

My blackcaps are in a row, three feet apart. An iron pipe sunk into the ground next to each plant provides support for each plant’s clump of stems. With pruning finished, I tied a piece of rope to the pipe and then around the clump of stems, a gloved hand cozying the thorny stems into position while my ungloved hand tied the rope, à la Michael Jackson.Tying blackcap with gloved hand

Rotten Plums

I wish that pruning was all that my plum trees needed. With this being such a good year for fruits generally, I was very hopeful for a good crop. And they looked fine up until a week ago, when the fruit started ripening — and rotting.

Brown rot is the culprit, mostly the handiwork of the fungus Monolinia fruticola. Characteristic powdery, gray masses of spores form on the surfaces of rotting fruits, which eventually dry to become “mummies.” Brown rot is not new to me; I’ve experienced it on peaches, nectarines, and plums in the past. It also attacks apricots, cherries, and other “stone fruits” (Prunus genus). Typically, a plant bears well for a couple of years while the fungi are building up, and then full-fledged, annual attacks begin.Brown rot

The usual recommendation to hold the fungus at bay is, first, to remove sources of inoculum by cleaning up all infected fruit in summer and mummies in winter, and pruning away dead, infected twigs. That’s quite a job on a big plum tree.

I sprayed my trees with sulfur many times this past spring. Sulfur is an organically approved fungicide, used by gardeners and farmers for thousands of years, that is effective against brown rot. But only for a few days. Hence my repeated sprays, evidently not repeated enough.

The easiest approach would be for me to grow brown rot resistant varieties.

Plumquest Begins

So now I am embarking on a plumquest, my search for plums that taste good and are resistant to brown rot. Resistant genes must lurk somewhere — actually right in my yard, on the wild plums. They hardly ever show fuzzy grayness; they also don’t taste very good.

I now remember a pertinent page I photocopied many years ago. Shuffling through piles of papers on my desk, I come across the page, from a scientific-looking paper, entitled “Range of known genetic traits in Plum cultivars.” That’s a start, and the list on the page includes one of my favorite plums, the Green Gage, also known as Reine Claude Verte, as resistant. Shiro, which I grow with some success, is only listed as “tolerant.”

My next queststep is on the web, bringing me to a publication entitled “The Cultivated Native Plums and Cherries,” authored by Liberty Hyde Bailey in 1892. I immediately ordered a reprint to make it easier to sort through the many varieties and their gustatory and pest potentials.

Once suitable varieties are identified, the next queststep is to locate trees or, more likely, stems for grafting, to bring here to the farmden. I will report on my plumquest as events unfold.

THE WEATHER, AND BLACKCAPS

Dry Soil

    Digging a hole to bury an animal last week gave me new respect for the plant world. Each shovelful brought up dusty, light brown soil, even to a depth of more than two feet. That’s expected, since it hasn’t rained more than 1/4 of an inch here for the past five weeks.
    With their leaves flagging in midday, trees and shrubs don’t exactly look spry. Still, they are alive, even some spring-planted trees and shrubs which have had little time to spread their roots deep and wide.

    Appearance of a soil can be deceiving. There’s some water lurking within those pores, water held tightly by capillary attraction. After heavy rains or irrigation, all soil pores get filled with water, a situation as bad for plants, if it lasts too long, as dry soil. Plant roots need air as well as moisture; air gets sucked in once gravity drains water from the largest soil pores.
    From then on, capillary attraction is what holds moisture in the ground — a pleasant situation for plants because the roots can tap into the more loosely held capillary water while they breathe freely. I prepare for possible droughts when planting by digging relatively small planting holes, which minimizes the amount of ground loosened up, in turn, among other benefits, preserving capillary networks in the soil. (Mulching and watering, right after planting, also helps.)
    Eventually, more and more of the loosely held capillary moisture gets sucked out of the ground by plants and evaporation. At some point, there’s still moisture in the soil, but what’s left is in the smallest pores and right against soil particles. It’s tightly held capillary moisture, water that plants can’t access. They wilt. When moisture levels drop to what’s known as the “permanent wilting point,” plants die.
    We’re not there yet and now, toward the end of the season, woody plants do have a Plan B: They can just drop their leaves, reducing moisture loss from stems and roots, and segue into winter on stored energy and moisture. To a point.

Cold Air

    If it’s not one thing, weather-wise, it’s another. On September 26th, I woke to find parts of the lawn hoary with frost. I’m not complaining. Frost should be expected, on average, around that date around here. Except that I’ve been spoiled for the last few years by much later frosts, frosts, so late that I pulled out old tomato plants because chilly weather drained tomatoes of their flavor rather than frosty weather killing the plants.Endive, lettuce, and old tomato plants
    Also, no complaints because the September 26th brought only a light frost; temperatures just hit 32°F. and the hoariness was spotty, here and there. A light frost is a good thing this time of year. It signals plants to get ready for even colder weather. In preparing for cold, cell walls strengthen and permeability of cells to water is actively altered. Even subtropical plants like peppers and tomatoes toughen up, with some chilly preparation, so that they can now tolerate temperatures that drop even a few degrees below freezing.
    Tender vegetables, frost or no frost, on the wane, have left the door open to vegetables that enjoy the cool weather of autumn. Most of the garden now presents a verdant sight of beds lush with lettuce, Chinese cabbages, winter radishes, endive, turnips, cabbages, arugula, mustard greens, carrot tops, and leeks, all ready for harvest, at my leisure, over the next few weeks.

Fall Black Raspberries

    Segueing over to the fruit world, I’m still harvesting the last of the blackcaps (black raspberries) of the season. Blackcaps? Anyone familiar with this fruit, abundant in the wild and often cultivated, knows that they ripen in midsummer.

Niwot blackcap, now ripe

Niwot blackcap, now ripe

    Last year I planted two new varieties of blackcap, Niwot and Ohio’s Treasure. With most blackcaps, canes just grow their first year, then fruit their second year. (During the second year, new canes are also growing, to fruit the following year, so a planting bears fruit every year.) Niwot and Ohio’s Treasure bear fruit at the end of the canes’ first year of growth, in late summer and autumn. Those same canes — I think — then continue bearing the following year, in summer, just like most blackcaps.
    I haven’t yet decided whether Ohio’s Treasure or Niwot offer the better berry, but it’s nice to be harvesting fresh berries this late in the season.

A FRUITFUL YEAR IN THE OFFING

 More Fruits to Plant!?

Pawpaw, tastes like crème brûlée

Pawpaw, tastes like crème brûlée

   You’d think, after so many years of gardening and a love of fruits being such a important part of said gardening, that by now I would have planted every fruit I might ever have wanted to plant. Not so!
    Hard to imagine, but even here in the 21st century, new fruits are still coming down the pike. I don’t mean apples with grape flavor (marketed as grapples), a mango nectarine (actually, just a nectarine that looks vaguely like a mango), or strawmato (actually a strawberry-shaped tomato).
    There are plenty of truly new fruits, in the sense of kinds of fruits hardly known to most people, even fruit mavens. Over the years, I’ve tried a number of them. Aronia is a beautiful fruit that makes a beautiful juice, so it’s getting more press these days. I grew it and thought it tasted awful. Goji’s another one in the public’s eye for it’s many health benefits and ease of growing; it also tasted terrible and I also escorted that plant to the compost pile.
    Some lesser known kin of raspberry had greater potential. I planted arctic raspberry, which grows as a groundcover and has been used in breeding for the good flavor it imparts to its offspring. The plant never bore for me. Salmonberry and thimbleberry similarly had gustatory potential but never bore well in my garden. I’ll give these plants another try someday.
    I’m tentative about honeyberries, which are blue-fruited, edible species of honeysuckle that bear young, fruit early in the season, and weather cold to minus 40 degrees F.. The “blueberry-like fruit” is so only in being blue. I planted a couple of bushes about 20 years ago and was not impressed with their yield or flavor — but I admit to neglecting the plants. More importantly, a lot of breeding has been done to improve the plants since I put my bushes in the ground. Stay tuned for my tastebuds’ report on the flavor of recently planted Blue Mist, Blue Moon, and Blue Sea honeyberries.

Some Fruits Are So Easy — And Tasty

    Reading what I just wrote might give the impression that planting any fruit except apples, peaches, and cherries — the usual, that is — leads to either failure or tentative flavor. Again, not so!
  

Persimmons, nashi, figs, and grapes

 Uncommon fruits adaptable over large swathes of the country that are easy to grow and have excellent flavor include pawpaw, American persimmon, gooseberry, black currant, hardy kiwifruit, Nanking cherry, and alpine strawberry — all documented in detail in my book Uncommon Fruits for Every Garden. All these plants grow and bear with little or no intervention on my part (and are available from such nurseries as www.onegreenworld.com and www.raintreenursery.com).

    Seaberry (Hippophae rhamnoides) didn’t make it into the book, which includes only “dessert fruits,” that is, those you can enjoy by just popping them into your mouth. But I’m happy I gave these bushes some of my real estate. Juiced, diluted, and sweetened, the delectable flavor is akin to rich orange juice mixed with pineapple. What’s more, the bushes are decorative and tolerate neglect, cold, drought, and deer.

New Fruits

    This spring I’m planting a new kind of a somewhat familiar fruit, back raspberries. They’re also called blackcaps, and grow wild along woodland borders, which is where I gather my harvest. (A ripe blackcap comes off the plant with a hollow core, like a thimble, in contrast to a ripe blackberry, whose core persists.)
    Blackcaps have perennial roots but their stems are typically biennial, growing only leaves their first year, fruiting in midsummer of their second year, then dying.

Blackcaps, ripe last summer

Blackcaps, ripe last summer

    Two new blackcap varieties, Niwot (www.noursefarms.com) and Ohio’s Treasure (www.hartmannsplantcompany.com), do this one better: They start to bear on new canes towards the end of the first season, then bear again on those same canes, now one-year-old, in midsummer of the following year. You reap two crops per year, one in midsummer and one in late summer going on into fall. Or, for easier care but only one crop per year, the whole planting is mowed to the ground each year for a late summer-fall harvest.
    These two-crop blackcaps, just like two-crop (sometimes called everbearing) red and yellow raspberries, have the added advantage of bearing their first crop the same year that they are planted. My plan is to plant in mid-April, even though right now more than a foot of snow still blankets the ground.

Vegetables Are So Easy

    Snow or no snow, I’m sowing vegetable seeds, the second wave of the season. (My seed sources are www.fedcoseeds.com, www.sustainableseedco.com, www.johnnyseeds.com, and www.reneesgarden.com.) Today, the lineup includes the new varieties (for me) Tuscan Baby Leaf kale, Tiburon Ancho hot pepper, and Round of Hungary and Odessa Market sweet peppers. With encores for their good past performance are Gustas Brussels sprouts, Early Jersey Wakefield cabbage, Winterbor kale, and Carmen Sweet, Sweet Italia, and Italian Peperocini sweet peppers.
