Future Tense, Present Tense
/14 Comments/in Fruit, Planning, Pruning/by Lee ReichPast 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. 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.
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.

Thirst
/13 Comments/in Gardening, Soil/by Lee ReichToo Much or Too Little?
The current deficit of rainfall reminds me of the importance of watering — whether by hand, with a sprinkler, or drip, drip, drip via drip irrigation — in greening up a thumb.
Not that watering is definitely called for here in the “humid northeast;” historically, cultivated plants have gotten by mostly on natural rainfall. Historically, vegetable gardens also weren’t planted as intensely as they are these days. In one of my three-foot wide beds, for example, brussels sprouts plants at eighteen inches apart are flanked on one side by a row of fully grown turnips and on the other side by radishes. Five rows of onions run up and down another bed.
The rule of thumb I use for watering is that plants need the equivalent of one inch depth of water once a week.
This approximation doesn’t take into account the fact that my bed of sweet corn is thirstier than is my bed of onions, that my plants drew less water up from the soil during a recent calm, cloudy day than they will with today’s bright sunlight and breezes, and that warmer temperatures speed water loss. Still, an inch a week is a good approximation, one very workable around here where periodic rain allow some wiggle room in watering. Not so in parts of California and similar climates that remain reliably bone dry all summer.
A sprinkler, or a hand-held hose with a spray rose for small areas, and some randomly placed straight-sided cans to catch water are an easy way to tell how long to leave the spigot on to get that inch depth of water. Usually, about an hour, once a week, is what it takes. (That’s a long time to stand still holding a hose.) Unless it rains. Then less might be needed.
A rain gauge is an inexpensive way to know whether what seems like a soaking rain is really so. Or monitor soil moisture directly. Dig a hole, poke your finger into the soil, or, even better, purchase a “moisture meter” for less than $15; plunge the metal probe a few inches into the ground and read on the dial whether the ground down there is “dry,” “moist,” or “wet.” You want it moist.
Thirst Quenching a Drip at a Time
My vegetable plants get their thirst quenched with drip irrigation rather than a sprinkler. The idea of a drip system is to drip water into the soil at about the rate which plants are removing it. That doesn’t occur once a week, but every bright day, all day long.
That one inch per week rate translates to about three-quarters of a gallon per square foot. My drip system is on a timer, and the time needed to apply this amount depends on the rate of flow from each emitter as well as the spacing of emitters.
After a lot of calculations and approximations (many years ago), I determined that dripping for one-half hour per day would be about right. But, as I wrote, plants drink all day long, not just once a day. My drip timer can turn on and off at three specified times per day, so the plants get their thirst quenched three times spaced out during daylight hours at ten minutes per session. My old timer offered six sessions per day; then, plants got six waterings of 5 minutes each.
Done. All I have to do is check every once in a while that all systems are go, which is one reason my drip lines run above ground. I can watch the dripping.
I do have to get out the watering can for the lettuce seedlings, the third planting of the season, that are soon to be set out, as well as for the recently planted row of carrot seeds and other recent seedings and transplants. Supplemental watering until roots of new plants stretch down into the region of the drip line’s wetting front, which spreads with the shape of an ice cream cone downward beneath each spot of dripping water.
(I’ll be leading a hands-on workshop on drip irrigation August 18th at the garden of Margaret Roach in Copake Falls. For more information, go to Margaret’s website, and type my name in the “search” box.)
Engineered Orifices
Note that I haven’t mentioned “soaker hoses.” Although the water oozes out from these porous hoses, they are not really “drip irrigation.” Sure, the water just oozes out slowly. But they’re inconsistent in output not only with water pressure and elevation, but also with time. And roots can grow inside buried soaker hoses, further muddying the water.
A real drip line has water emitters spaced six to twelve inches apart along their length, and those emitters aren’t mere holes punched in tubing. They are engineered orifices, designed to be relatively consistent in output with changes in incoming water pressure and changes in elevation along the line. They also are self-cleaning in case debris gets into the line.
And Now, A Word About Fireflies
Fun fact: Fireflies (which I knew as “lightning bugs” in my youth) are more than whimsy on a summer night; they’re also a gardener’s friend, feeding on, among other creatures, slugs.
Berries Begin
/13 Comments/in Fruit, Gardening, Planning/by Lee ReichGreen Thumb Not Necessary
Every day, for some time now, my strawberry bed has yielded about five cups, or almost 2 pounds of strawberries daily. And that from a bed only ten feet long and three feet wide, with a double row of plants set a foot apart in the row.
Good yield from a strawberry bed has nothing to do with green thumbs. I just did what’s required to keep the plants happy and healthy. To whit . . .
I planted the bed last spring to replace my five-year-old bed. About five years is about how long it takes for a strawberry bed to peter out due to inroads of weeds and diseases, including some viruses whose symptoms are not all that evident.
To keep my new plants removed from any problems lurking in the old soil, I located the new bed in a different place from the old one. Further forestalling problems, plants came not from a generous neighbor and not from my old bed, but from a nursery selling “certified disease-free” plants.
I chose to grow them in a “spaced plant” system (which does not involve getting plants high, ha, ha) but allows each plant a square foot of space. Throughout the growing season, I clipped off any runners and daughter plants attempting to establish themselves and crowd into the mother plant’s space.
Other growing systems allow for runners, which makes for more economical planting of a bed but reduced initial yield. Given free rein, though, new plants eventually become the worst weed in any strawberry bed; they must be dealt with in some way.
Did I mention that the new bed, like the old one, was in the vegetable garden, where the soil is rich in nutrients and organic matter, with plants’ thirst quenched daily via drip irrigation?
In late December, when the ground had frozen about an inch deep, plants were snuggled beneath mulch as protection from winter cold. Straw, pine needles, wood shavings — any loose organic material will do.
Come spring, just as soon as plants began to awaken, I pulled back new growth beneath the mulch and tucked it under the plants’ leaves. I also trimmed off any dead leaves. The new job for the mulch was then to keep the soil moist and the soon-to-form ripening berries clean of soil.
That’s it, for all those berries, fresh picked every morning. Every morning for a little while longer, that is. I planted a “junebearing” variety of strawberry, Earliglow, known for earliness and good flavor, but bearing only for a few weeks in June. Other varieties, so called “everbearing” and ”day neutral” varieties, bear repeatedly through the season.
Once Earliglow stops bearing for the season, the bed will need renovation and, through the season, its runners pinched off weekly to keep each plant “spacey.”
Better Berries
You might wonder: Why such a relatively small planting of strawberries, and why only junebearers? This admission may be sacrilege: I’m not a big fan of strawberries. I like the fruit well enough, but mostly because they are the first fresh fruit of the season.
(One other fruit does beat out strawberries as the first fruit of the season. They are honey berries, a kind of edible honeysuckle. Their flavor, thus far, has not impressed me. Breeding and cultivating honeyberries is in its infancy. They’re perhaps where apple was 2000 years ago, and the future might bring more flavorful ones.)
Back to strawberries . . . another of their deficiencies, in my view, is that you have to crawl for the fruit. And, as mentioned previously, although technically perennial, beds should replanted in a new location every 5 years or so.
The Best Berries
The fresh strawberries came on the scene on the tails of last year’s frozen blueberries, one of my favorite fruits. Perfect. (The loss of frozen blueberries is softened by the freshness of the strawberries.)
And just as the fresh strawberries fade out for the season, fresh blueberries will begin yielding this season’s bounty. Also, at the same time, black currants and red currants. And then black raspberries, and then . . . and on and on.
