I Clothe The Ground

Sowing My Oats

Whew! Just made it under the wire. Sowing cover crops, that is. (Cover crops are plants grown solely to improve the soil.)

With the vegetable garden still filled to the brim, now overflowing with cabbage, kale, mustard, arugula, lettuce, Chinese cabbages, and radishes, with even corn and peppers still yielding well, where am I going to find room to plant a cover crop? Despite the cornucopia, some plants — the corn, peppers, and other warmth-loving vegetables — are on their way out. As they peter out, it’s too late in the season to sow any more radishes, lettuce, or any of the other cool season crops; there’s not enough time or sunlight for them to mature.

No reason to leave a recently cleared bed of early corn, early beans, or okra bare, so I planted those beds to a cover crop. Problem is that after a certain time of year, there’s not enough time or sunlight for even a cover crop to grow enough to do some good for the soil. My date for that is early October; further south it will be later; further north, earlier.

Right after clearing a bed of spent vegetable plants, I go over it carefully to remove every weed. Then I smooth the ground and give it a thorough watering to give the cover crop plants a quick start. What plants? Oats.Oat cover crop sequence

I grow oats as a cover crop because I never till the soil in my vegetable beds. Oats loves the cool weather of fall and early winter, quickly sprouting into a lush, green carpet. By February, though, that lush carpet turns tawny and flops down on the ground, dead. Come spring, I could plant right through that mulch. Or, it could be rolled up with a grass rake, or just pulled off barehanded; removing it speeds soil warming.

Other good cover crops for no-till gardens are barley and, to also add nitrogen to the soil, peas. Gardeners who till their ground usually plant rye grain as a cover crop. It survives winter, then grows with vengeance in spring; hence the need for tillage.

Back to that watered bed. I sprinkle the bed with oat seeds, then top the bed with an inch of compost. Green sprouts poke through that compost blanket in a couple of days or so.Oats sprouting

Is It Worth It?

Planting a cover crop in a bed that gets an annual dressing of an inch depth of compost may seem like “carrying coals to Newcastle.” After all, one potential benefit of cover crops are that they add organic matter to the soil. That inch of compost is already organic matter, and plenty of it.

In fact, I have never observed any better growth from a bed that has been cover cropped over one that received only the compost blanket. And for some reason, the cover cropped beds always seem to have more weeds in them in spring — surprising, since a cover crop should be shading or pumping out natural chemicals to suppress weeds! Perhaps some weeds insinuate themselves in fall in among the oat plants, where I can’t see them. My plan, this spring, is to cover some of the cover-cropped beds for a week or so with a black blanket (recycled billboard tarp, available online) which will warm the ground up quicker and snuff out potential weeds.

Even cover crops’ potential benefit of enriching the ground with organic matter doesn’t always pan out, and surely not the way I plant them. Organic matter is largely carbon. Young plants are relatively rich in nitrogen and poor in carbon, a ratio that reverses as the plants age. A young cover crop, then, doesn’t add organic matter to the soil; its excess nitrogen could even contribute to the oxidation and loss of organic matter. Oats planted this time of year grow lushly, but never mature enough to tip the scales in that early ratio of nitrogen and carbon.

(I dive into more depth about cover crops in my book Weedless Gardening.)

Cover Crop Brings Many Benefits

Still, I’m planting a cover crop — for some of its other benefits.

Rain and snow in the coming months can wash nutrients down and out of the soil. The oat roots, as long as they are alive, can suck up those errant nutrients and keep them nearer the surface for next season’s vegetable plants. Cover crops also soften the impact of rain pounding on the soil, preventing erosion.

As roots of cover crop plants push through and ramify in the soil, they nudge soil particles around to improve tilth (structure of the soil) making it crumbly, all to the liking of plants. These roots also team up and nourish other organisms, such as fungi, that also improve tilth. Channels of varying size are left in the soil as roots die off and rot away. Such channels provide easy conduits for new roots, as well as for air and water.

And finally, I’m planting cover crops for myself. With green fading from the landscape into reds, yellows and tawny browns, it’s refreshing to look upon the green carpet rather than bare soil in the vegetable garden.Oat cover crop

Some Good, Some Bad

Picking Pecks and Pecks of Peppers

Warm — no, hot — weather going on and on keeps tomatoes, cucumbers, and peppers chugging along, restrained only by diminished sunshine. Still, before real autumn weather rolls in and decimates these warmth-loving plants, it’s time to do some evaluation of this season before it fades into memories that meld with previous seasons.

As usual, there are successes and failures. Good — no, great — are this year’s peppers. I credit the rousing success mostly to My choice of two varieties. The first was an old variety, Sweet Italia, aka Sweet Italian or Italian Sweet. Other varieties are available with similar names; the names are similar, but not the same, as are the fruits.

Sweet Italia has two problems: The seed is hard to find; and the plants flop over under their weight of fruit. Both problems are easily solved: Save seed (Sweet Italia is not a hybrid, so seeds come “true” as long as the plants are sufficiently distant from other pepper varieties); stake the plants. Sweet Italia is especially notable for bearing large and relatively early crops of deliciously sweet red peppers even under northern growing conditions. It’s much, much tastier than Sweet Ace, which is often grown commercially as an early ripening, sweet red pepper.Italia, Escamillo pepper

The other pepper variety of note is Escamillo, larger than Sweet Italia and also delicious, in a different way. Escamillo, bred by Johnny’s Selected Seeds, ripens yellow. Like Sweet Italia, Escamillo is a corno di toro, shaped like the horn of a bull.

Blight!!

Balancing my peppery successes are two failures celery and celeriac. Plants looked healthy from the time I sowed seed, indoors in February, until the transplants went out in the garden, in early May. It was downhill from there.

Plants are stunted and their leaves are spotted by disease. The spots are very distinctive, tan with black edges, and angular in outline. The tan areas lacked pycnidia, small, black propagules visible with the naked eye, so the disease is not one of the fungal diseases that afflict celery and celeriac.Celery bacterial blight

A web search of symptoms and images identified the problem as bacterial blight (Pseudomonas syringae pv. apii). Cool, wet weather exacerbates the condition, and we did have some of that this summer. The fungus can also spend the winter in the soil, which makes a good case for crop rotation, not planting any member of a family of plants in the same place oftener that every 3 years. I did move my celery and celeriac far from previous two locations, though.

I’m pinning the blame on seedling flats that were not sufficiently cleaned. Usually, I just give them a rinse after use; next year they’ll also get a spritzing with alcohol. 

Infected seed could also have been the culprit — doubtfully in my garden. The celeriac seed was from a reputable nursery. What’s more, the celery seed comes from my own plants, in the greenhouse. Those plants also self-seed in the greenhouse, and the volunteer plants that come up in the greenhouse look fine. (I thin them out, letting the best ones grow to provide celery all winter, and then self-seed again in spring.)

If infected, seed could be de-contaminated with a hot water treatment, 122°F for 25 minutes. Or with time. Seeds more than two years old don’t carry disease.

Other plans for next year are to be even more thorough with end-of-season cleanup of beds and to rip out of the ground any plants suspected of harboring disease as soon as noticed.

As a last resort, copper sprays, which are approved for organic use, could be applied. I probably won’t do that; it takes the fun out of just popping fresh vegetables into your mouth in among the beds. I have plenty of other good stuff to eat out there.

A Fruitful Season

In fruits, pears have been outstanding this year. Not because of any greenness of my thumb; everybody around here had good crops of pears. Must be something about the weather.

Also outstanding have been grapes. Again, not because of the greenness of my thumb, but because I have so many vines and so many different varieties. Despite weather conducive to diseases, there were — and still are — plenty of good grapes for eating.

Flowers did fine this year, except Lemon Gem marigolds, one flower that I try each year to sow enough of to define the leading edges of the beds in the vegetable garden.Lemon Gem in path They typically germinate poorly for me, but they occasionally self-seed. I couldn’t bear to remove the few that popped up in the main path near the leading edges of the beds. Their general absence makes those few all the more outstanding.

Taste And Aroma

Old Peaches

The peaches on a friend’s tree were small, marred with bacterial spot disease, and still showed some green on their skins. So burdened with fruits was the tree that it had burst asunder from their weight, splitting one of the main limbs.

Still, the friend insisted that the peaches tasted good. As further enticement, the tree had a history, having sprouted on the grounds of a nearby 18th century house that had an orchard. The tree was evidently cold hardy also. So I twisted one fruit off and took a bite. In spite of being not quite ripe, the fruit was delicious, quite sweet — as is usual with white peaches such as these — and with an old-fashioned, intensely peachy flavor.Heirloom peach

I took up the offer to take a small bag of them home with me. And not only for eating. My plan is to save the seeds from many of them for planting and for making into new trees that should taste very much like their mother tree. Peaches are self-pollinating, in contrast to apples and pears, so progeny often resemble their parent. Peaches also bear within just a few years from seed so I could weed out some or all plants whose fruits were not up to snuff.

The first step to a peachy future was to crack open the shells surrounding each seed, and then drop the seeds into a plastic bag filled with potting soil on the workbench in my unheated garage.

In their natural environment, peach seeds ripen in summer but wouldn’t sprout until spring. If they sprouted immediately, winter cold would likely kill the very young seedling. Hormones within the seeds sense when winter has ended by the number of accumulated hours at cool (30 to 45°F) temperatures.

The number of hours depends on the genetics of the tree but for most hardy fruit trees, about 1000 hours, or about a month and a half, does the trick. And I do intend to trick them, to give them an early start on the season, indoors. The more they grow each season, the sooner they bear.

I’d like them to sprout in early March, so will put the bag of potting soil and peach seeds into my refrigerator in early December. Once they sprout, I’ll pot a few up and, once they emerge from the soil, move them to the sunniest window or the greenhouse, then, when weather warms, outdoors.

It’s a Weed, It’s a Garden Plant, It’s a . . .

Some plants straddle the fence of being defined as a weed. Case in point is Sweet Annie. On looks alone, the plant could easily fall to one side of the fence, qualifying only as a weed. It’s nothing more than a nondescript, upright plant — until it bends over from it’s own weight — that’s green, clumps of them sprouting all over the place. Despite being a member of the Daisy Family of plants, Sweet Annie’s flowers are small, pale green, and not notable.Sweet Annie

I, and many other gardeners, grow the plant for its rich, resiny aroma. Bundles of them are for sale from many farms at Maine’s Common Ground Fair; it’s the signature aroma there. So I also grow Sweet Annie to bring me back, olfactorily speaking, to my good times at the Fair.

As a sometime weed, Sweet Annie is, of course, easy to grow. I first planted it 3 years ago, sowing it, unnecessarily, in pots for later transplanting. No need to plant it again; it self-seeds enthusiastically, my job now being to contain that enthusiasm. 

Amazing how that plant can move around. It managed to find its way from the back of my house to the front of my house without going around either side. It manages to sprout in spaces between the bricks of my terraces holding the thinnest slivers of soil.

Sweet Annie is sometimes cultivated as a row crop for harvest and extraction of artemisinin, which has some medicinal uses. As for me, I just weed out plants in the wrong place (as defines a weed), and harvest a few bunches to hang near the door for an olfactory treat as I brush past it.  

How Pesky And Interesting

/0 Comments/in , , , /by

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

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

/0 Comments/in , , , /by

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 bedA 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

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

The Book of Pears
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.

The Destroyer To The Rescue

/5 Comments/in , , , /by

Predatory Helpers

Some of the figs — the varieties Rabbi Samuel, Brown Turkey, and San Piero — started ripening last week. With their ripening, I am now in a position to claim victory over the mealybugs that have invaded my greenhouse fig-dom for the past few years.
Mealybugs look, unassumingly, like tiny tufts of white cotton, but beneath their benign exteriors are hungry insect. They injects their needle-like probiscis into stems, fruits, and leaves, and suck life from the plants, or at least, weaken the plants and make the fruits hardly edible.

Over the years I’ve battled the mealybugs at close quarters. I’ve scrubbed down the dormant plants with a tooth brush dipped in alcohol (after the plants were pruned heavily for winter). I’ve tried repeated sprays with horticultural oil. I put sticky bands around the trunks to slow traffic of ants, which “farm” the mealybugs. And I’ve rubbed them to death with my fingers when I came across them on the stems. All to no avail. The mealybugs always made serious inroads into the harvest.

Mealybugs finally have been quelled this season thanks to another insect, the aptly named “mealybug destroyer” (Cryptolaemus montrouzieri), available from www.insectary.com. To soldier along with the mealybug destroyer, I also ordered some green lacewing (Chrysoperla rufilabris) eggs. Besides attacking the mealybugs, the lacewings prey on aphids, seizing the aphids in their large jaws, injecting a paralyzing venom into them, and then sucking out their body fluids. With good reason, lacewings are also called aphid lions.

Mealybug destroyer

Mealybug destroyer

I ordered the first batch of predators in early summer. After recently noticing a buildup of mealybugs again, I ordered another batch. The mealybug destroyer and aphid lion populations may have plummeted after they ate all the bad guys, or they may have found their way to greener pastures via the many openings in the greenhouse.

The smallest amount of either pest that could be purchased could have policed a greenhouse much larger than mine, so the predators were relatively expensive: about $80 per shipment, with shipping. Still, I estimate the potential ripening of about 160 figs, which brings their cost to $1 per fig. Not bad for a dead ripe, juicy, ambrosial fruit that, with each bite, transports me back thousands of years to the Fertile Crescent, where figs originated.

Help From The Queen

A visitor to my greenhouse might have thought it looked weedy this summer. Tall flower stalks of Queen Anne’s lace grew with abandon, cilantro flowered and then their seed heads flopped down willy nilly, lettuce grew bitter as the plants bolted, and mustard greens shot up stalks capped with yellow flowers. There was reason for this wild wantonness.
The purpose of all these flowers was to encourage the adult mealybug destroyers and aphid lions to stick around. Flowers of plants in the Carrot Family, such as Queen Ann’s Lace and cilantro, the Daisy Family, such as lettuce, and the Mustard Family, such as, of course, mustard, provide nectar and pollen that the predators enjoy.Queen anne's laceThe Carrot Family Helps Out

I also encouraged beneficial insects outdoors, in my vegetable gardens, by growing or, at least, letting grow, some of these same plants.

Add to that list dill, another member of the Carrot Family, which I always let flower and set seed in the garden. Those seeds become next year’s dill plants with no extra effort on my part except to weed out excess self-sown seedlings.

For some reason, dill did not self-seed in the garden the past two years, so this year I bought and planted seed. “Planted” might be too specialized a term for what I did. In fact, I just tore open the packet of seeds, poured them into my hand, and waved my hand as I let the seeds fly. Like magic, seeds sprouted a few weeks later.
This season’s dill not only encouraged beneficial insects and provided some ferny leaves and seed heads for flavoring, but also provided beauty. The variety was ‘Fernleaf,’ which grows dwarf, compact plants that also are slower to make flower heads. Perhaps it was the compactness of the flat heads of greenish yellow flowers or the denser backdrop of green leaves, but the plants captured my attention every time I walked by them. Still do, because they’re still blooming.Fernleaf dill

Queen Anne’s Lace also appeared in my garden with no extra effort on my part. Not only from self-seeding, as a weed. But also from an occasional rogue carrot seed from those I planted. Queen Anne’s Lace and carrot are the same genus and species, carrots having been selected and bred to make fatter, juicier, tastier, and orange-er (or, these days, purple-er) roots.

Here, at least, this season was particularly welcoming of QueenAnne’s Lace. The meadow next to the vegetable gardens has been dotted white with an abundance of their flowering heads.

The Bad and the Good

Winecaps, Not For Me

My successes with growing shiitake mushrooms emboldened me, this past spring, to venture further afield, to wine cap mushrooms (Stropharia rugosoannulata). After all, it’s been billed as “prized, delicious” and “edible when young.”

Their quick production also prompted me to give them a try. As a matter of fact, my spring “planting” started bearing a couple of weeks ago. A bed can also be refreshed or a new bed can be inoculated from an old bed for repeat performances.Stropharia mushroom

Let’s go back to spring, to my planting. Wine caps grow very well in wood chip mulch, something that’s aplenty on my farmden. My berry bushes are mulched, my pear trees are mulched, as are the paths in my vegetable gardens. Why not do double duty with those mulches?

A few years ago, I attempted just that, laying a thick mulch of chips atop my asparagus bed in spring. Two problems: The thick mulch almost killed the plants, and the weather was very dry for weeks on end. Mushrooms need moisture.

This past spring, I pulled back twigs and other debris from a patch of ground beneath a Norway spruce tree and laid down a few inches of hardwood chip mulch. After sprinkling the purchased spawn over the mulch, I topped everything with another inch or two of, this time, wood shavings.

For this spring’s planting, I also decided to water, so set up a sprinkler. Rain fell pretty consistently all season long, obviating the need for further watering.

The tasting: To me, the mushrooms were tasteless. Sure, I could have sautéed them with butter and garlic; then they would have tasted like butter and garlic. (Disclaimer: Your results may differ from mine.)

My taste for wine cap mushrooms went down another notch when I more recently read a caution to eat them moderately and not more than two days in a row. My yard abounds with plenty of other good tasting, healthful food, so I’ll pass on the wine caps.

Seaberries For Me

On to more tasty items. Seaberries (Hippophae rhamnoides). The harvest is in, the first harvest from my 2013 planting. I wanted them for juice and, on the recommendation of seaberry expert Jim Gilbert of www.onegreenworld.com, planted Titan, Leikora, and Orange Energy.

Seaberry plants are either male or female. Only female plants bear fruit; to do so, they need pollen from a nearby male, which I also planted. One male can sire up to 8 females.

Seaberry, Titan

Seaberry, Titan

In addition to yielding very healthful berries, seaberries further earn their keep as landscape plants. (I’ve seen them planted as ornamentals in New York City’s Battery Park.) The bush’s thin, olive green leaves are the perfect backdrop for the bright orange berries, clustered thickly right along the stems.

And there’s the rub. Long, sharp thorns also cluster along the stems, making harvest a potentially painful proposition.

I used the method Jim recommended for harvest, and that is to cut stems heavily laden with berries into 6 inch long pieces, put them into a covered plastic tub, and then freeze them. The frozen berries came off the stems when the tub was shaken vigorously. All I had to do then was to pick out the stems, and then winnow the leaves from the fruit in front of a fan.

The berries are now back in the freezer, to be made into juice at my leisure. That’ll involve cooking them in a little water, mashing them with a potato masher, and then straining. My previous planting yielded a delicious juice once diluted with 1/8 part water and sweetened with 1/8 part maple syrup or honey.Seaberry juice

This season’s juice should be even better because the berries taste better than the previous varieties I planted. Especially good — even straight from the bush — in the new planting is the variety Titan. Seaberry generally tastes, to me, like very rich orange juice with the addition of pineapple or passionfruit. Titan has more of a tangerine-y flavor.

Permaculture-esque

Wine cap mushrooms and seaberries are both plants beloved by permaculturalists. The mushrooms for the little care they need, and their use of mulched ground. The seaberries, also for their low maintenance, their beauty, and their enrichment of the soil with nitrogen.

Seaberry bush

My seaberries are in a permaculturalesque planting, along with elderberry, highbush cranberry, nannyberry viburnum, rugose rose, Korean pine, and aronia. They’re all easy to care for. They’re all very ornamental. The only ones that taste good or yield anything are the seaberry and the rugosa roses.

Picked At Peak Of Perfection

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?

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.

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.

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.
