Fiery Colors

Colorful Predictions

As leaves are just starting to color up, the question is, “Will the autumn leaf show be good this year?” First off, whether or not it’s good, global warming has pushed showtime forward a bit each year. Around here, the peak of the show used to be the middle of October; nowadays it’s the third week in October.

Back to predicting how good the show will be this year  . . . Throughout summer and into autumn most leaves are, of course, green, which is from chlorophyll. Chlorophyll must be continually synthesized for a leaf to stay green. The shorter days and lowering sun of waning summer are what trigger leaves to stop producing it, letting other pigments lurking there out of hiding.

The yellow and orange colors of leaves are always lurking there, thanks to carotenoid pigments, which help chlorophyll do its job of harvesting sunlight to convert into plant energy. I offer thanks to carotenoids for the especially warm, yellow glow they give to gingko, aspen, hickory, and birch leaves.

Tannins are another pigment, actually metabolic wastes, that all summer are hidden by chlorophyll. Their contribution to the fall palette are the season’s subdued browns, notable in some oaks and enriching the yellow of beeches.

Because leaves harbor carotenoids and tannins all summer long, nothing particular about autumn weather should either intensify or subdue their autumn show. The only glitch could be an early, hard freeze that occurs while leaves are still chock full of chlorophyll. In that case, cell workings come screeching to a halt and all that’s left are frozen, green leaves that eventually drop without any fanfare.

Autumn color also spills out reds and purples, most evident in red maples and some sugar maples, scarlet oak, sourwood, blueberry, and winged euonymus. Those reds and purples come from yet another pigment, anthocyanins. Except for trees like ‘Purple Fountain’ beech and ‘Royal Purple’ smokebush, whose leaves unfold dusky red right from the get go in spring and remain so all season long, in most leaves anthocyanins do not begin to develop until autumn.Japanese maple

Anthocyanin formation requires sugars, so anything that we or the weather does to promote sugar accumulation in autumn will increase anthocyanin levels in leaves. Ideal weather conditions for sugar accumulation are warm, sunny days to maximize photosynthesis, and cool, but not frigid, nights to minimize nighttime burning up of accumulated sugars.

The many cloudy and rainy days for the past weeks don’t bode well for a great autumn show of leaf color. Less red because less anthocyanin is formed, and any that does form is diluted.

Our Hand in the Color Palette

Weather plays its part in autumn color but we can also have a hand in its development. One way is to ratchet up the reds and purples to make sure that leaves bask in light. I plant a tree where light is adequate (for that species) and, as necessary, prune so that branches don’t shade each other. Street lights don’t count as light, and actually have a negative effect, disrupting the signal that days are getting shorter and it’s time to slow chlorophyll production.

We also can ramp up the autumn show by planting trees genetically programmed for good autumn color. Among the most colorful-leaved trees and shrubs—which, besides those previously mentioned, include goldenrain tree, hickory, ironwood, black tupelo, and fothergilla—individuals within each species might pack a bigger wow than the others. Hence the spicebush variety ‘Rubra’, brick red in fall, or ‘Wright Brothers’ sugar maple, whose leaves become a mottling of gold, pink, orange, and scarlet.

Admittedly, the weather trumps (sorry) all.

(For more about some of the science going on behind the scenes in your garden, and how to put it to practical use, see my new book, The Ever Curious Gardener: Using A Little Natural Science for a Much Better Garden, from which the above is adapted.)

A Brainy Orange

There’s another orange in the garden this autumn, and it’s not in the leaves or the fruit — the hardy orange — about which I recently wrote. It’s the osage orange (Maclura pomifera).

I grew my two trees from seeds extracted from a local osage orange I found on the ground. Each tree is about 25 feet tall and intimidating for their large, mean thorns. Trees are either male or female, so I lucked out, ending up with one of each, allowing the female to bear.

Why would I plant such a tree? For interest: This native of the midwest was, thanks to its thorns, a predecessor of barbed wire for containing livestock; also the primo wood sought after by Native Americans for their bows; and the wood is among the most rot-resistant of any tree.

The softball-sized fruit also is very interesting, with all its convolutions looking something like a green brain. Although related to fig and mulberry, it’s not at all edible. The fruit is claimed, without substantiation, to repel insects and spiders in and around homes.Osage orange fruits

Making My Bed(s); The “Best” Tomato

/13 Comments/in , , /by

Buckwheat Beds

About a month ago the greenhouse was looking messy as oxalis, grasses, chickweed, and other weeds were starting to carpet the mostly bare ground.  An unacceptable situation, considering that a month hence — now — I would need the space for planting in preparation for fall and winter.

The first step back in August was, obviously, to clear away the weeds, pulling almost each and every one out, roots and all. As long as weeds aren’t too overgrown or too abundant, the job is pleasantly satisfying. Moist soil also helps.

Pulling out weeds differs from the usual approach of preparing the soil by tilling it to discombobulate and bury weeds. I avoid tillage because it exposes buried weed seeds to light, which is just what new weeds need to germinate and grow. Tillage also burns up valuable humus and discombobulates not only the soil, but also resident fungi, earthworms, and other beneficial organisms.

I wasn’t ready to plant anything in some of those greenhouse beds a month ago, yet I hate to look at bare soil. (Mother Nature is equally repulsed by bare soil; she clothes it with weeds.) So I planted buckwheat, sprinkling the seeds thickly over the beds.Buckwheat sprouting in greenhouse Buckwheat provides a quick and temporary cover of the bare ground. Sprinkling it with water assured its getting off to a quick start.

Finally, I covered the ground with an inch-thick layer of compost. That amount of compost will nourish whatever’s growing in the beds for a whole year. It also provides cover to hold moisture around the buckwheat.

Only a few days later, buckwheat sprouts were already peeking up through the compost blanket. They went on to grow quickly in the heat of the season. Aboveground the dense foliage was, I hoped, doing its job of shading out any new weeds trying sprout, something for which buckwheat is famous. Buckwheat growing in greenhouseBelow ground, the roots were latching onto nutrients that might otherwise leach away, bringing them up into the roots, stems, and leaves.

By the first week in September, buckwheat stems were flopping down onto the ground. Anyway, it was time to remove them to make way for planting the greenhouse. I was anxious to see what kind of new weed growth, if any, presented itself beneath the buckwheat.

The goal was to remove the buckwheat without disrupting the soil. My fingers easily raked off the tops which detached themselves from the roots that were left intact in the soil.

Buckwheat lived up to its reputation: I could hardly find a weed anywhere!

Oat Beds

Outdoor beds in the vegetable garden have been receiving similar treatment, with some wrinkles. Those beds that are finished for the season, not needed for autumn harvest, get cover crops of oats rather than buckwheat. Buckwheat doesn’t like cool weather and is killed by the slightest frost.

The advantage of oats over buckwheat is that oats enjoy cool weather, growing lush and green, and even tolerate quite a bit of cold weather. Oat cover crop sproutingSo any bed no longer needed for autumn vegetables and cleared before about the end of September gets oats (and compost). After the end of September, short days don’t provide enough light for the oats to grow enough to warrant planting.

One benefit of oats, buckwheat, and any other cover crop is that they keep up appearances. Oat cover cropWhile I have great respect for soil, it’s not pretty to look at — and being bared isn’t good for the soil or the plants growing in it. I’d much rather look at a uniform, green carpet than bare, brown soil.

The Best(!!!!) Tomato

No need to rush summer vegetables out the door quite yet. I had the opportunity to try out a new tomato this season, Garden Gem, which has received a lot of fanfare.

Time travel back to 1995, when tomato breeder Harry Klee of the University of Florida, began to suss out what makes a great-tasting tomato using heirloom varieties, gas chromatography, and tasting panels. Then fast-forward to 2011, a field in Florida, where Harry tastes the result of his effort to breed a great-tasting tomato that is disease resistant and productive, and stands shipping. And so was born Garden Gem, the offspring of the luscious heirloom variety Maglia Rosa and the variety Fla. 8059, excellent in all characteristics except flavor.

Garden Gem scored as high as the heirloom parent for flavor.Garden Gem tomatoAs it turns out, even taste is a matter of taste: To me, Garden Gem is not a great-tasting tomato; not even a good-tasting tomato. It lacked any sweetness or richness to smooth out the acidity, which is basically all I tasted.

(The “perfect supermarket tomato,” as it was billed, was also a commercial flop, for now at least. It’s reported that Garden Gem too large for a small tomato and too small for a large tomato and, anyway, that consumers don’t really care about flavor.)

In the Wild

Row, Row, Row My Boat, and Then!

Paddling down a creek — Black Creek in Ulster County, New York — yesterday evening, I was again awed at Mother Nature’s skillful hand with plants. The narrow channel through high grasses bordered along water’s edge was pretty enough. The visual transition from spiky grasses to the placid water surface was softened by pickerelweeds’ (Pontederia cordata) wider foliage up through which rose stalks of blue flowers. Where the channel broadened, flat, green pads of yellow water lotus (Nelumbo lutea) floated on the surface. Night’s approach closed the blossoms, held above the pads on half-foot high stalks, but the flowers’ buttery yellow petals still managed to peek out.

Soon I came upon the real show, as far as I was concerned: fire engine red blossoms of cardinal flower (Lobelia cardinalis). Coming upon this flower in the wild is startling. Such a red flower in such shade?

So many shade plants bear white flowers which, after all, are most easily seen in reduced light. Only twice before had I come upon cardinal flower in the wild, and both times the blooming plant was in deep, deep shade; it was a rare treat to see such a lively color in the shade.

Though the stream bank was not in deep shade, the cardinal flower was still a treat. And not just one cardinal flower but groups of them here and there along the way. Cardinal flower Black CreekMore than I have ever seen in the wild. (In Chanticleer Garden outside Philadelphia is a wet meadow planted thickly with cardinal flowers.)

Nature’s Hand

Two other landscape vignettes come quickly to mind when I marvel at natural beauty. 

The first are the rocky outcroppings in New Hampshire’s White Mountains; placement of these rocks always looks just right. In addition, the flat areas against the rocks and in rock crevices in which leaves have accumulated to rot down into a humus-y soil provide niches for plants. Among the low growing plants are lowbush blueberries and lingonberries.

Lingonberry in White Mountains

Good job at “edible landscaping” Ms. Nature!

The other vignette was (one of many) in the Adirondack Mountains. Picture a clump of trees and a large boulder. Now picture those trees on top of the boulder, their roots wrapping around and down the bare boulder until finally reaching the ground on which the boulder sat. A scene both pretty and amazing.Tree roots and rock

But My Fruits and Vegetables are Better(?)

Mother Nature might have it in the landscape design department; not when it comes to growing fruits and vegetables though. There may be some disagreement here: I contend that garden-grown stuff generally tastes better. And for a number of obvious reasons.

In the garden, most of what we grow are named varieties, derived from clones or strains that have been selected from among wild plants, or have been bred. Named varieties generally are less bitter, sweeter, and/or more tender. Perhaps also high-yielding and pest-resistant.

In some cases, “cultivated” plants offer too much of a good thing. Humans long sought to sink their teeth into the sweetest sweet corn, harvesting ears at their peak of perfection and then whisking them into already boiling water to quickly stop the enzymatic conversion of sugars to starches. In the 1950s, a “supersweet” gene was discovered that quadrupled the sugar content of sweet corn — too sweet for me and and lacking the richness of an old-fashioned sweet corn variety such as Golden Bantam.

A nutritional case can be made against cultivated varieties of plants. Studies by the US Department of Agriculture have shown modern fruits and vegetables to be lower in nutrients than those tested 50 or so years ago. Have we excessively mined our soils of minerals? No. Breeding for bulk, along with pushing plant growth along with plenty of water and nitrogen fertilizer, has diluted the goodness in plants.

In Eating on the Wild Side Jo Robinson contends that breeding for sweeter and less bitter plants inadvertently selects for plants lower in many nutrients and phytochemicals.

All this makes a good case for growing more “old-fashioned” varieties, such as heirloom tomatoes and paying closer attention to how plants are fed.Heirloom tomatoes (Compost is all my vegetables get.) And perhaps focussing more on what food really tastes like. Does Sugarbuns supersweet really taste like corn. Or a candy bar?

And eat some wild things. Purslane is abundant and, to some (not me) tasty now. As is pigweed, despite its name, a delicious cooked “green.” I mix it in with kale and chard for a mix of cultivated and wild on the dinner plate.

Watering — in the Rain?

/5 Comments/in , , , /by

Why Are Pots Thirsty?

With recent rains of more than 3 inches over the last couple of days, you’d think that the last thing on my mind would be having to water anything. But you’d be wrong. Plants in pots — and I have plenty of them, some ornamental and some tropical and subtropical fruits — don’t get the full benefit of all that water.

Potting soils are, and should be, more porous than any garden soil to maintain good aeration within the confines of a pot. About a one inch depth of water is needed if you’re going to thoroughly wet a 12 inch high column of potting soil. If a flower pot is, for example, only 6 inches high, only 1/2 inch depth of water would be needed; and so on.

A lot of my potted plants didn’t drink in that 3 inches of rain that fell over the past couple of days. Some of the plants are shielded from the sky by overhanging house eaves. And the leaves of other plants — excepting amaryllis and calla lily which have strappy, upright leaves — deflect water that could have fallen into the pot.

If you don’t believe me, tip a potted plant out of its pot following a heavy rain, and check how dry the soil is down deep within the pot. Even easier, purchase an inexpensive moisture meter whose metal probe, when slid into the soil, reports moisture deep down.

(Sort of) High Tech Solution

When I first started gardening, I knew I would eventually move from the cottage I was renting. My mini-orchard was in pots and travel-ready. I kept that “orchard” watered by hand, which wasn’t so bad. The problem was that in the heat of summer, some plants needed their thirst quenched twice a day, which kept me from leaving my home for more than a few hours.

These days, technology has come to the rescue.

The first techno-solution has been drip irrigation. A simple, battery-operated timer at a spigot sends out water on a twice daily schedule to banks of potted plants. Also at the spigot, following the water line right after the timer, are a filter and a pressure reducer. automatic watering, potsThe fittings for wending water through tubes around corners and up into pots are low pressure fittings; the pressure lowers water pressure to a mere 20 psi.

Once the 1/2 inch main line makes its way to a group of potted plants, a 1/4 inch plastic line, plugged into the main line with, of course, a low pressure fitting, carries the water up to the ground surface of each pot.

If the water merely exited at this point, pots closer to the water source would be under higher pressure and so get more water than those more distant. And pots that were shorter or at lower elevation would likewise get more water. So I slid an emitter, that reliably puts out 1/2 gallon of water per hour, no matter what the incoming water pressure, on the end of each 1/4 inch line.

Capillarity to the Rescue

I have a number of lowbush blueberry, lingonberry, hollyhock, carnation, and blazing star plants growing in pots 4-inches and smaller. I’ll eventually plant them out in the garden. Until then, the plants need regular watering Snaking 1/4 inch tubes to all these pots would create a tangled nightmare.

Enter capillary mat watering. All these smaller pots sit on a mat of absorbent fabric spread over a tray held a couple of inches above a pan of water. Irrigation, capillary matPart of the capillary mat dips into the reservoir of water, which gets sucked up into the mat and then sucked up into the potting soil through the drainage holes in each flat-bottomed plant pot.

I periodically have to remember to add water to the reservoirs. Or, rather, “had to” because I ran a few of those drip tubes into the reservoirs, enough to keep them topped up with water to keep pace with plant use.

And a Presentation of Interest

I’ll be doing a presentation on August 18th on THE SCIENCE, ART, FUN, AND TASTY FRUIT OF ESPALIER in Copake Falls, NY. The presentation will explore the theory and the practice behind the pruning and orienting of branches to create an espalier. This decorative, usually 2-dimensional form, offers high yields of high quality fruit on a plant or plants that can be free-standing, decorating a wall or fence, or even creating the fence itself! I’ll go over which fruit plants work best and the branch pruning and orienting techniques that create and maintain espaliers that look good and yield especially delectable fruit.

Heat and Drought Come and Go

/4 Comments/in /by
(The following is a adapted from my recent book, The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden, available through the usual outlets as well as, signed, from me at www.leereich.com/books.)

Plants’ Dilemma in Beating the Heat

Last week, with a spell of dry weather, I wrote about irrigation; then it rained. As I write, we’re experiencing searingly hot weather; thank me for the cooler weather that will surely follow.
The heat is hard on us humans, but pity plants in the heat of a hot, summer day. While I can jump into some cool water, sit in front of a fan, or at least duck into the shade, my plants are tethered in place no matter what the weather.
And don’t think plants enjoy extreme heat. High temperatures cause plants to dry out and consume stored energy faster than it can be replenished. Stress begins at about 86° Fahrenheit, with leaves beginning to cook at about 105°.
One recourse plants have in hot weather is to cool themselves by transpiring water. This loss of water from leaves can cool a plant by about 5° Fahrenheit. Over 90 percent of the water taken up by plants runs right through them, up into the air, exiting through little holes in the leaves, called stomates. Carbon dioxide and oxygen, the gases plants need to carry on photosynthesis, also pass in and out through the stomates.
All goes well provided there is enough water in the soil. If not, stomates close, transpiration and photosynthesis stop, and the plant warms. Even if the soil is moist, stomates might close in midsummer around midday if leaves begin to jettison water faster than the roots can drink it in.
So plants are put in a bind. Should they open their pores so that photosynthesis can carry on to give them energy, but risk drying out, or should they close up their pores to conserve water, but suffer lack of energy?

Beat the Heat with CAM

Enter cacti and other succulents (all cacti are succulents—that is, plants with especially fleshy leaves or stems—but not all succulents are cacti. The fleshy stems and leaves of succulents can store water for long periods. After more than a year without a drop of water, my aloe plant’s leaves still look plump and happy.
Besides being able to store water in their stems and leaves, jade plants, aloes, cacti, purslane, and other succulents have another special trick, Crassulacean Acid Metabolism (CAM), for getting out of photosynthesis of dehydration conundrum. They work the night shift, opening their pores only in darkness, when little water is lost, and latching onto carbon dioxide at night by incorporating it into malic acid, which is stored until the next day. Come daylight, the pores close up, conserving water, and malic acid comes apart to release carbon dioxide within the plant, to be used, with sunlight, to make energy. 
I’ve actually tasted the result of this trick in summer by nibbling a leaf of purslane—a common weed, sometimes cultivated—at night and then another one in the afternoon. Malic acid makes the night-harvested purslane more tart than the one harvested in daylight.Purslane

C4 Beats the Heat Also

Another group of plants, called C4 plants, function efficiently at temperatures that have most other plants gasping for air and water. C4 plants capture carbon dioxide in malate, the ionic form of malic acid, which is a four-carbon molecule, rather than the three-carbon molecule by which most plants—which are “C3”— latch onto carbon. The enzyme that drives the C4 reaction is so efficient that C4 plants don’t have to keep their stomates open as much as do C3 plants. The C4 pathway also does its best work at temperatures that would eventually kill a C3 plant, and cells involved in the various steps are partitioned within the leaf for greatest efficiency.
C4 plants are indigenous to parched climates, but not uncommon visitors in gardens every- where. Corn is a C4 plant. (Cool climate grains such as wheat, rye, and oats are C3 plants.) Look- ing at my lawn, I see another C4 plant. Corn hillsHot, dry weather in August drives Kentucky bluegrass, a C3 grass, into dormancy. Not so for crabgrass, a C4 plant, which remains happily green.
I also find some other C4 plants, in addition to corn, in my garden. As many vegetables and flowers flag, all of a sudden lambsquarters and pigweed, both C4 weeds (or vegetables, for those who like to eat them), appear as lush as spinach in spring.

With a Little Help From Us Gardeners

Can we gardeners do anything to help out our plants in hot weather? Keeping the garden watered helps. Sprinkling or misting plants could keep them cool without their having to pull water up from the soil.
But the 30 gallons of water that runs up through a tomato plant in a season, or the 50 gallons that flows through a corn plant, is for more than just cooling these plants. It also carries nutrients from the soil into the plant. So it’s debatable how well a plant would grow with too much misting. And besides, wet plants are predisposed to disease.
A better alternative to sprinkling plants is to grow plants adapted to the climate and the season. Lettuce, spinach, peas, and radishes are not the plants to grow for harvest in August. At least not in full sunlight; that’s why, in midsummer, I grow lettuce in the shade beneath trellised cucumbers.
Tomatoes, cucumbers, peppers, melons, and squashes, although they are neither cacti nor C4 plants, can take the heat. And, of course, so can C4 plants like corn, purslane, and vegetable amaranth.

Too 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.

Finger in soil to test for moisture

Finger in soil to test for moisture

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. Hand wateringUsually, 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.

Digital moisture probe.

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. Dripline with beansMy 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.Drip timer

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

Green 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.Strawberry harvest
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.
Netted strawberriesOnce 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.)

Last frozen blueberries, fresh picked strawberries

Last frozen blueberries, fresh picked 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.

This Sunday, June 24th, 2018, from 1-4:30 pm my garden/farmden is open to the public as part of the Garden Conservancy’s Open Days program. The Garden Conservancy is an American nonprofit organization founded in 1989 and dedicated to preserving exceptional gardens and landscapes. The $7 admission cost to each Open Day garden helps fund their efforts. For more information about my farmden and other local gardens open that day (and through summer), go to https://www.gardenconservancy.org/open-days/garden-directory/springtown-farmden
