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

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.

All You Need To Know About Blueberries

Interested in growing your own blueberries? It’s easy, if you meet their basic needs, all of which, including varieties, harvest, and other pressing questions about growing blueberries, will be covered at my upcoming BLUEBERRY GROWING WORKSHOP. The workshop will take place on my New Paltz farmden on July 22, 2018 from 9:30-11:30am, at a cost of $48. Registration is a must.

Playing Around With Stems

Top Doggery

My pear trees look as if a giant spider went on a drunken frolic among the branches. Rather than fine silk spun in an orderly web, strings run vertically from branch to branch and branch to ground. Yet there is method in this madness. Mine.
 
As I spell out in my new book, The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden, plants produce a natural hormone, called auxin, at the tips of their stems or at high points along a downward curving stems. This hormone suppresses growth of side branches along the stem, allowing growth from a bud at the stem tip or high point be the “top dog,” that is, the most vigorous shoot.

Within any plant a push and pull goes on between fruiting an stem growth. Both require energy, which the plant has to apportion between the two. The more vigorously growing a stem, the less fruitful it is.

All this talk of hormones and inherent stem vigor is more than academic; it can translate into delicious fruits.

Pear trees tend to grow very vigorously, especially in their youth, with many vertically oriented branches. A certain amount of stem growth is, of course, desirable; leaves are needed for harvesting sunlight for energy and stems are needed on which to hang fruit.

But pear trees, especially in the youth, tend to put too much of their energies, too much for me, at least, into stem growth. The result is that they can take long time to settle down and begin bearing fruit.

Hence, the strings. I can change my pear trees’ habits by merely tying down branches, reducing the effect of that auxin so that growth is more uniform along a length of the stem. And, as important, slowing growth nudges the energy balance in the direction of fruiting.

Branch bending

The one branch on each young tree that I do not tie down is the main vertical stem, which is the still developing trunk off which grow the main side branches. I want this stem to keep growing upward. Also, I have to be careful not to create a downward arch when tying down any stem. You know why: a very vigorous shoot pops up from the high point in that arch.

More Fruit or More Growth?

Branch bending is not only for coaxing a tree into fruiting. On young branches, it creates a wide angle between a branch and the developing trunk. Wide angles here have been shown to result in good anchorage, sturdy side branches that can carry a weight of fruit.

Suppressing the vigor of side branches also ensures that they won’t compete with the developing trunk, which needs to be top dog.

And using string to play around with plant hormones isn’t needed on every fruit tree. At the other extreme from pear in its growth and fruiting habits is peach. Peach is naturally very fecund, and becomes naturally so at a very young age.

One reason for peach’s fecundity is that it bears all its flowers and fruits along stems that grew the previous season. Every year new stems grow that bear flowers and fruits.             

Beauty, Fruit, and Fun

All this concern with auxin, vigor, and fruiting comes most prominently into play with espalier, which is the training of a tree to an orderly, often two dimensional form. The tracery of the branches themselves adds to the decorative value of the plant.Pear espalier

Fruiting espaliers, besides being decorative, produce very high quality fruit. Pruning and branch bending maintain a  careful balance between yield and stem growth, and the form of the plant allows leaves and fruits to bathe in sunlight and air.

(Micro)climate Change

/3 Comments/in , , /by

As the train rolled southbound along the east bank of the Hudson River, I took in the varied landscapes along the opposite west bank. Spilling down the slope to the river on that bank at one point was what appeared, from a distance, to be a vineyard. I was envious.

(I never could understand why the region here is called the Hudson Valley. Along much of the Hudson, the land rises steeply right up from river’s edge. Where’s the valley?)

I wasn’t envious of the riverfront site of the vineyard property. I wasn’t even envious of having a whole vineyard  of grapes. (I cultivate about a dozen vines.)

What I did envy was the microclimate of the site. Microclimates are pockets of air and soil that are colder, warmer, more or less windy, even more or less humid than the general climate, due to such influences as slopes, walls, and pavement. 

The vineyard was not that far from my home, but the microclimate was worlds apart. Every parcel of land, from a forty-acre farm field to a quarter acre lot, will have some microclimates, and siting plants with this in mind can spell the difference between whether or not they thrive or even survive. Microclimate, early tulipsI’m banking, for instance, on the slightly warmer temperatures near the wall of my house to get my stewartia tree, which is borderline hardy here, through our winters. (It has.) And I expect spring to arrive early each year, with a colorful blaze of tulips, in the bed pressed up against the south side of my house. Proximity to paving also warms things up a bit.

Microclimate for cold, microclimate for warmth

Microclimate isn’t always about trying to keep a plant warmer in winter, or speeding up growth in spring. It’s also useful for keeping plants cooler. By training my hardy kiwifruit (Actinidia spp.) vines right up against the shaded, north sides of their hefty supports, I keep the sun off their trunks in winter and avoid the splitting that occurs when trunks are warmed during winter days, then precipitously cooled as the winter sun drops below the horizon. Microclimate, lingering snowBy planting the coveted blue poppy in a bed on the east side of my house, I hoped to give the plant the summer coolness that it demands. (That east bed was still too sultry; the plants collapsed, dead.)

Microclimates are important when growing fruit plants that blossom early in the season because frozen blossoms do not go on to become fruits. Early season bloomers need microclimates that are slow to warm up.

South facing slopes stare full face at the sun, so these slopes warm up early in spring and are warmer in both summer and winter. Therefore, a south facing slope—even if the grade is only slight—can be used to hasten fruit ripening on a plant like persimmon, which blooms late but needs a long season when grown near its northern limits.

Right after I push soil over the first seeds of sweet corn that I plant, I firm it over that hole with my foot at an angle to make a south-facing depression in the ground. That mini-slope will warm up just a wee bit sooner than flat ground.

The sun glances off north slopes, delaying their warming in spring and keeping them cooler in summer. Such a microclimate is ideal for an early blooming fruit tree like apricot or peach, and for plants, such as sweet peas, that enjoy cool summer weather. Likewise ideal for such plants is near the north side of a building, where shade remains through winter and the early part of the growing season.

If a slope actually has some elevation to it, the air is going to cool by one degree Fahrenheit every three-hundred feet going up the slope. If I had sloping ground, which I don’t, and sought a cooler location for planting, I’d avoid planting at the very top of the slope, though, because the upper reaches are usually windy.

A cold spot, here

Ideal vineyard site, from plant perspective, in Germany

Counterintuitively, the very bottom of a slope will also be a cooler microclimate. On nights when the sky is clear, with no clouds or leafy trees to block re-radiation of the sun’s heat from the ground back to the heavens, the air at ground level cools. An “inversion” occurs, with warmer air higher up. The cold air, which is denser than warm air, flows downhill to settle into depressions, just as a liquid flows downhill. A low point would be the worst possible location for planting strawberries, which grow near ground level and whose early blossoms are threatened by late frosts in spring. Any dense fence or shrubbery on a slope stops the downward flow of cold air, which will pool, just as dammed water would, near the upper side of the barrier.

Among the fruits I grow are apples, peaches, plums, and pears, all of which tend to bloom early. My site, unfortunately, is just about the worst possible site for growing these fruits. Apple blossomsThe cold air that settles here on clear spring nights increases the likelihood of late frosts and also causes moisture to condense on the plants, leaving them more susceptible to disease. Hence my envy for that sloping vineyard site.

Doing Good with Saw and Lopper

Fruitful Pruning

To begin, I gave the bush in front of me a once over, eyeing it from top to bottom and assuring it that the next few minutes would be all to its good. It was time for my blueberries’ annual pruning, the goals of which were to keep them youthful (the stems, at least), fecund, and healthy.

Blueberries galore

Blueberries galore

I peered in at the base of the plant, eyeing now the thickest stems. Blueberry bushes bear best on stems up to 6 years old, so the next move was to lop or saw any of these stems — usually only 3 or 4 of them, more on a neglected plant — as low as possible.

Sammy & me, pruning blueberries

Sammy & me, pruning blueberries

To keep track of the ages of individual stems, I mark off the age of them each year with a Sharpie. Just kidding! The thickest ones are the oldest ones, and 6-year-old stems are generally an inch or more in diameter on healthy bushes.

Removing those stems that are over the hill frees up space for younger stems to develop. Each year blueberry bushes send up new sprouts from ground level, usually a few too many of them. They need to be thinned out so they don’t crowd each other as they age. I leave a half dozen or so of the most vigorous new sprouts, lopping all others to the ground.

That’s pretty much all there is to pruning a blueberry bush. With the very oldest and some of the very youngest stems cut to the ground, the bulk of pruning the bush is finished.

Blueberry bush, before & after pruning

Blueberry bush, before & after pruning

  I’ll also snip off any dead stems, remove a branch here and there where they are congested, and shorten any stems that will arch to the ground when laden with fruit.

That’s it. Finished, except to step back and admire my handiwork.

And Now, For Other Shrubs

The same pruning done on blueberry could, in essence, be applied to lilac,Lilac in flower forsythia, mockorange, hydrangea, and any other informal shrub. This technique is known as rejuvenation pruning because, over time, the above ground portion of the shrub is annually rejuvenated. In the case of blueberry, the roots live unfettered year after year but the bush never sports stems more than 6 years old. A perennially youthful blueberry bush can go on like this, bearing well, for decades like this.

Not all shrubs perform best on stems up to 6 years old. Some, such as kerria, snowberry, rambling roses, and summer-bearing raspberries perform best on 1-year-old stems. So every year those 1-year-old stems are lopped to the ground and the youngest stems are thinned out.

Some shrubs, such as butterfly bush, everbearing raspberries, and red twigged dogwood, perform best on new stems. In this case, the whole plant gets lopped to ground level each year. (Everbearing raspberries actually bear on both new stems and on 1-year-old stems, so could be pruned as in the previous paragraph. That takes more time but does yield a midsummer crop on the 1-year-old stems and a late summer and fall crop on the new stems.)

At the other end of the spectrum in shrub pruning are witch hazel, tree peonyTree peony blossoms, rose-of-sharon, climbing roses, and flowering quince. These shrubs are among those that perform well year after year on the same old, and always growing older, stems. They also grow few or no suckers each year. The upshot is that thesis shrubs are the easiest to prune: Don’t.

I detail the ages of stems that are “keepers” for every shrub, plus other details in pruning all kinds of plants, in my book The Pruning Book.

Getting Formal

All this pruning refers to informal shrubs. For formal shrubs, such as the privet hedge near one edge of my yard, I put aside the lopper, pruning shears, and pruning saw, and get out the hedge trimmer. Shearing all the youngest twigs, working, this time, higher in the bushes rather than down near ground level, elicits repeated branching which results in dense growth.

To keep this formal hedge clothed from head to toe in leaves, I keep the row of plants narrower towards their upper portions. This lets sunlight beam down on the shrubs from top to bottom.

Northern Figs? Yes!

Faking The Subtropics

At first blush, the setting would not seem right for fig trees. There they were, in pots sitting on my terrace — so far so good — but with snow on the ground around them. Figs? Snow?Potted figs and snow

Figs seem so tropical but, in fact, are subtropical plants. And it does sometimes snow in subtropical regions. Climatewise, subtropics are defined as regions with mean temperatures greater than 50 °F with at least one month below about 64 °F. Further definitions exist but the point is that it does occasionally snow in subtropical regions; temperatures just never get very cold.

My potted figs couldn’t have survived our winters outdoors. They wintered in my basement, where winter temperatures are in the 40s. Cool temperatures are a must to keep the stored plants from waking up too early indoors, then, because the weather is too cold to move them outdoors, sprouting pale, sappy shoots in poor indoor light. Even sunny windows don’t hold a candle (pardon the pun) to sun in the great outdoors.

Sleep, Sweet Figs

My goal is to keep the plants asleep as long as possible and then to move them outdoors just as soon as temperatures are unlikely to plummet low enough to do them harm. I figure that date was yesterday, April 2nd. Most fig varieties tolerate cold down into the 20s, some even lower.

Roots of all plants have evolved in, of course, the ground, where temperatures are more moderate than the air. So they can’t tolerate as much cold as can stems. With cold penetrating the exposed soil in pots, more so the smaller the pot, I have to keep an eye on the outdoor temperature and, if it gets too low, whisk all the pots into the shelter of the garage.

In the ideal world, temperatures will slowly warm without any dramatic lows or highs, and fig buds will gradually unfold into shoots along whose length will develop and then ripen juicy, sweet Celeste, Genoa, Excel, Ronde de Bordeaux, and Rabbi Samuel figs.Plate of figs

Cold concerns this time of year don’t apply to one of my potted figs, a Himalayan fig (Ficus palmata). I rooted a cutting of this plant a few years ago. It’s billed as being much more  tolerant of both cold and summer rain than common figs (F. carica), both assets for a fig in this part of the world. I have yet to see fruit from this plant.

Primal Urges?

What is it about figs that makes so many people want to grow them? I know of someone in Sweden who grows them. Even someone in Canada who has a collection of over 200 varieties (www.adrianosfigs.com)! Figs are an ancient fruit with origins in the Fertile Crescent, so is it some primal connection with the distant past that is the attraction?

A big part of the attraction is, of course the flavor of fresh figs, which is unlike that of the dried fruit. Market figs don’t make the grade because figs have to be picked dead ripe for best flavor, at which point they’re too delicate to travel much further than arm’s length from plant to mouth.

As would be expected of so ancient a fruit, hundreds of varieties exist — and perhaps thousands of names because more than one name has been ascribed to many varieties. My variety Rabbi Samuel, for instance, mentioned above, is, I know a made-up name. A friend made it up because he got it from some Hassidic Jews who had no name for it. And the frequently grown variety Brown Turkey is a name assigned to two different varieties, one more common on the west coast and the other more common on the east coast. And the east coast variety has a number of other names, including Everbearing, Texas Everbearing, and La Perpetuelle.

The first plant I ever grew once I got the gardening bug (in my 20s) was, in fact, Lee’s Perpetual (another name for eastern Brown Turkey). I grew it in a pot in a not very sunny window of the apartment I was renting. Not surprisingly, in retrospect, the plant never fruited.

Nowadays I think of the climate in which figs are native when growing my figs: cool, moist winters (as in my basement) and hot summers with plants baking in abundant sunlight. I now harvest plenty of figs.

Postscript April 6th: Temperatures of 22 °F perhaps prompted me awake at 3 am; I got up and lugged all 11 potted figs into the shelter of my unheated garage. 

This Bud’s for You

Swelling Buds

What an exciting time of year! After a spate of 50 plus degree temperatures, lawn grass — bare now although it could be buried a foot deep in snow by the time you read this — has turned a slightly more vibrant shade of green. Like a developing photographic film (remember film?), the balsam fir, arborvitae, and hemlock trees I’m looking at outside my window, have also greened up a bit more.

Going outside to peer more closely at trees and shrubs reveals the slightest swelling of their buds. Earlier in winter, no amount of warmth could have caused this. As a cold weather survival mechanism, hardy trees and shrubs are “smart” enough to know to stay dormant until warm weather signals that it’s safe for tender young sprouts and flowers to emerge.

These plants stay asleep until they’ve experienced a certain number of hours of cool temperatures, the amount varying with both the kind and variety of plant.

Once that cold “bank” has been filled, the plants merely respond to warming temperatures. Which, for many plants, is now.

Physiology aside, the buds provide an interesting winter diversion; look at their sizes, their shapes, their colors, and textures. (Admittedly, their interest would pale in the landscape exploding into flowers and leaves, when the buds anyway mostly disappear into flowers or leaves until later in summer when new ones re-form.)

More than just interest, buds are useful. Buds can be used to identify the kind of plant as well as whether flower buds are in the offing. Or perhaps that flower buds were in the offing but were damaged by winter cold.

Info from Buds

The first bit of information I glean from winter buds is plant identification. To begin, how are the buds arranged along the stem? Buds directly opposite each other, which is relatively rare for local trees, narrows the choice down to maple, ash, dogwood, and horse chestnut, or, as some people remember it, MAD Horse.

L to R: peach, pawpaw, fantail willow, viburnum, dogwood

L to R: peach, pawpaw, fantail willow, viburnum, dogwood

Of course, once I identify a tree as, for example, a maple, I have to look for other details, such as the bark, to tell if it is a red, sugar, silver, or Norway maple.

(A few less common trees also have opposite leaves, including katsura and paulownia, both non-native, and viburnums, some of which are native. Most shrubs have opposite leaves.)

Buds that are not opposite each other along a stem might be alternating along the stem, they might be whorled, or they might be almost, but not quite opposite, presenting a much wider field of plants from which to choose.

Then it’s time for a closer look at the buds themselves. Some plants—viburnums, for example—have naked buds, enveloped only by the first pair of (small) leaves, rather than the scaly covering protecting the buds of most other plants. Buds of plants such as maples have buds enclosed in scales that overlap like roof shingles. Or two or three scales might enclose a bud without any overlap, as they do on tuliptree.

Mature plants have two kinds of buds. Those that are longer and thinner will expand into shoots. Flower buds are usually fatter and rounder. I note how dogwood flower buds stand proud of the stems like buttons atop stalks — very decorative if you take the time to have a look. I take a look at a peach branch with its compound bud: a single, slim stem bud in escort between two fat flower buds.

Peach buds

Peach buds

Apple and crabapple flower buds occur mostly at the ends of stubby stems, called spurs, that elongate only a half an inch or so yearly. Pawpaws fruit buds are fat and round with a brown, velour, covering.

Practicalities aside, buds can predict what kind of flower show or fruit crop to expect, barring interference from late frosts, insects, diseases, birds, or squirrels. If peach fruit buds just sit in place rather than fattening as winter draws to a close, I’ll know that the night back in January when temperatures plummeted to minus 18 degrees Fahrenheit did them in, or at least some of them. 

More Winter Details

Back to winter plant identification and entertainment. Looking more carefully at these leafless plants promotes familiarity. Notice the intricacies of their various barks; shagboark hickory, sugar maple, persimmon, white birch, and, my favorite, hackberry,

Hackberry bark

Hackberry bark

are very characteristic. Note twigs’ color, presence of ridges or lenticels (corky pores), even their taste or aroma. The aromas of yellow birch (wintergreen aroma), sassafras, and black cherry (almond) practically shout out their identification.

Snow Mulching

Only four inches of snow fell a a couple of weeks ago but I decided anyway to go outside and mulch. And shovel snow. And shovel snow and mulch.

What I was trying to do, besides clear snow from the driveway, the paths, and the doorway to the greenhouse, was to create a microclimate. A microclimate is a small area where the climate is slightly different from the general climate.

One group of plants in need of this special treatment are my maypops, Passiflora incarnata. Yes, Passiflora genus is that of passionflower, and maypop is a hardy species of passionflower, native to eastern U.S.. It bears the same breathtaking flowers, whose intricate arrangement of flower parts was used by Christian missionaries to teach native Americans about the “passion” of Christ, as the tropical species. White maypop flowerAnd, like the tropical species, flowers are followed by egg-shaped fruits filled with air and seeds around which clings a delectable gelatinous coating. You know the flavor if you’ve ever tasted Hawaiian punch.

Maypop parts ways with tropical passionflowers, which are woody vines, in being an herbaceous vine. The roots live year ‘round but the above ground portions of the plant die back each winter.

Besides creating a microclimate for the maypops, I also chose to plant them in an existing microclimate to their liking. That is on the south side of my woodshed, where the sun bears down to provide extra warmth in summer. (Another goal was to let the vines each summer cover a trellis that would give the woodshed some shade to prevent the firewood from drying out to much.) These plants of southeastern U.S. like their summers hot.

Soil moderates temperatures so never get as cold in winter as the air — or, in summer, as hot as the air. Five feet down, soils remain at a balmy 50°F year ‘round. Shallower depths are commensurately colder in winter and warmer in summer than deeper down.

Maypop is borderline hardy this far north. Insulating the ground around the plants will keep temperatures around the roots from dropping too low. Hence the snowy mulch.

As maypop grows through the summer, new flowers and then fruits appear. The longer the growing season, the more fruits the plants bear. Although I want to keep the ground from getting too cold in the depths of winter, I’d like it to warm up quickly in spring to get the plants going.

Wood chips, straw, snow, or any other mulch is going to put the brakes on soil warming, so, ideally, the mulch should be removed after the coldest part of winter is past. Except if that mulch is snow, which will melt.

Ugly but Delicious

Wandering through the snow to the other side of the farmden, I come upon another fruit, this one ready to pick and eat right now! Medlar. (Medlar and maypop each warranted a whole chapter in my book Uncommon Fruits for Every Garden.)

Medlar fruits resemble small, russeted apples (a relative), tinged dull yellow or red, with their calyx ends (across from the stems) flared open. Medlar, fruit in basketIt’s peak of popularity was in the Middle Ages. And though popular, it was made fun of for it’s appearance; Chaucer called it the “open-arse” fruit.

That old-fashioned look extends to the tree itself, which even this time of year is attractive with the elbowed contortions of its branches. In spring, the blossoms, which resemble wild roses, are borne singly at the ends of branches and, opening late so that each is cradled in already opened whorl of leaves.

But back to the fruit; its got another quirk, besides its appearance. It’s inedible when first harvested. But after the fruit has sat for a couple of weeks or more indoors, a process called bletting, the once-hard, white flesh turns to brown mush.

Medlar, after bletting

Medlar, after bletting

Yechhhh! The flavor, though, has a refreshing briskness with winy overtones, like old-fashioned applesauce laced with cinnamon.

Fruits left on the tree also blet, and my trees are loaded with fruits.

Uh oh. Although medlar is generally pest-free, I see that many of the fruits have what looks like some sort of pest damage. Instead of the smooth, brown mush, flesh of damaged fruits is drier, almost powdery. What is it?

(Almost?) Hardy Orange

More snow more recently fell, and with it came bitter cold, which made me fear for the survival of my hardy orange, Citrus trifoliata. This orange is allegedly hardy to zone 5, but still . . .

The plant is only about four feet tall and there was plenty of snow so I just started piling snow on top of it. The ends of some branches remained exposed, which is okay because they can tell me whether the plant is really hardy.

Hardy orange bears flowers and fruits very similar to sweet oranges except that hardy orange fruits are bitter and very seedy. They could be used — in moderation — for flavoring, though. Citrus, Flying DragonHardy orange fruitMostly I grow it for the novelty of an outdoor orange tree, for the sweetly fragrant blossoms, and for the decorative, green, swirling, recurved spiny stems.

Come spring, I;’ll know if just how hardy the hardy orange really is. Temperature the night after covering it dropped to minus 18° Fahrenheit.

Life Goes On

The dark green wreath was tied with red ribbons and gliding towards me, in its progress stirring up snowflakes gently floating out of the grey sky. No, the wreath was not hanging from a horse-drawn sled, but was plowing through the frigid air affixed to the chrome grille of a gleaming white Cadillac! Here we are in the twenty-first century, still infusing a breath of life into our winters with cut evergreen boughs, just as did the ancient Egyptians, Persians, Jews, Christians, and Druids.

Whether for Christmas, for the ancient winter festival of Saturnalia, or for any other tradition, a wreath celebrates the continuity of life through winter. Evergreens are favorite wreath materials because their year long green flaunts winters’ apparently lifeless cold.

A few evergreen boughs tied together make a doorway more inviting or a room more cozy in winter, but a bona fide wreath creates something special. And the actual making of a wreath can be an end in itself this time of year.Wreath

Plenty of native and cultivated plants, many probably growing right in your backyard, could supply evergreen leaves for wreaths. Depending on the weather and the variety, needles of some junipers might still look bright green, although many turn purplish in the cold. Norway spruce always looks rich green, as do, with a softer look, the long, slender needles of white pine. With flattened sprays of scale-like leaves, arborvitae is another good choice, surely one of the best choices for a winter wreath when you translate its name to “tree of life.”

Don’t forget broadleaf evergreens also. Mahonia, holly, leucothoe, rhododendron, boxwood, and English ivy are suitable broad-leaf evergreens for a wreath. Indoors, none of the broadleaf evergreens will hold their leaves in a wreath as long as the needle-leaved evergreens.

To get a little wilder — more in keeping with the raucous Saturnalia celebrated in ancient Rome — use some evergreens with splotches or borders of yellow on them. No evergreen has all yellow leaves, but Gold Star and Kuriwao Sunburst junipers, for example, have yellow-tipped leaves. Midas Touch and Variegata are broadleaved evergreens, varieties of Japanese holly, with spots or splotches of yellow on their otherwise green leaves.

Okay, let’s calm down and get to some practical matters. Any wreath needs a support on which to mount the branches. That support could be a purchased styrofoam “doughnut” or one you make yourself from coat hangars. For an “organic” frame, readily available from the wild or backyard pruning, grape vines come to mind. Vines of bittersweet or virginia creeper would also work. Before grabbing at any wild vine, make sure you can identify and avoid poison ivy — it can cause rashes even this time of year.

Wrap any of these vines into a doughnut shape, weaving it into itself and weaving in new lengths as you go around and around. Wreath materialsA few loops of string or thin wire can unobtrusively firm everything in place.

Next, wire, glue or tuck small bunches of evergreens onto the base, with all the bunches facing the same direction. Be generous so as to create a harmonious backdrop for the colorful stuff that comes next.

A walk in the woods or around your yard should turn up some colorful fruits, even this time of year. Still abundant are wild rose hips, bittersweet, winterberry, and barberry. Other seed pods are also good as ornaments. Wreath, almost finishedBesides the obvious — pine cones — also consider the flattened silvery pods of silver dollar plant, the wiry ones of love-in-a-mist, and the shaggy manes of clematis. If yet more ornamentation is wanted, there’s always chains of cranberries or popcorn strung together.

When hints of spring are in the air and you tire of your wreath, just compost it or throw it in the woods (if made from all organic materials). For now, though, deck the halls.

End of Year Punch List

/6 Comments/in , , , /by

 

Winterizing

My carpenter friends, near the end of their projects, have their “punch lists” to serve as reminders what odds and ends still need to be done. I similarly have a punch list for my gardens, a punch list that marks the end of the growing season, a list of what (I hope) will get done before I drop the first seeds in the ground next spring.

(No need for an entry on the punch list to have the ground ready for that seed. Beds have been mulched with compost and are ready for planting.)

Hardy, potted plants, including some roses, pear trees, and Nanking cherries, can’t have their roots exposed to the full brunt of winter cold.plants, almost ready for winter I’ve huddled all these pots together against the north wall of my house but soon have to mound leaves or wood chips up to their rims to provide further cold protection.

I’ll save some leaves to protect strawberry plants. Their insulating blanket won’t go down until weather turns colder, with the soil frozen an inch deep, or else their evergreen leaves will rot beneath the leaves.

I’ll be digging out or cutting down a number of woody plants, some even 10 or 20 years old, in the next few days or weeks to make way for better ones. (Ruthless!) Anna hardy kiwifruit, short for Annanasnaya, grows very well but ripens a bit late and doesn’t have quite as good flavor as my other varieties: Geneva, MSU, and Dumbarton. So out it goes. The same goes for Mars, Concord, and Cayuga White grapes; their flavor isn’t up to snuff. And Halle’s Giant, Lewis, and Clark filberts, except that their shortcoming is their susceptibility to the disease filbert blight.

A 5 gallon bucket filled with equal parts sifted compost and soil will be ingredients for any potting soils I’ll need for seedlings from midwinter on. For the finished potting soil, I’ll mix in another 5 gallon bucket with equal parts peat moss and perlite.

One sunny day soon I’ll lean pitchforks, rakes, and shovels against the garden carts and brush them with linseed oil diluted with equal parts paint thinner. Tool handles, readiedAfter the handles have been wiped down, 10 minutes later, they’ll be in good condition for at least another year.

Pruning hardly needs to be added to my punch list. I’m reminded about this annual job every time I look out the window or walk out the back door.

Deer at Bay

Protecting some of my trees and shrubs from animals doesn’t make it to the punch list either — because it needs to be done by now! Young pears (Concorde, Abbe Fetal, and Lady Petre) and apples (Liberty, Macon, Hudson’s Golden Gem, Ashmeads Kernel, and Pitmaston Pineapple) already have their hardware cloth and/or plastic collars protecting their bottom couple of feet of growth.

What about branches higher up, the ones the deer would find tasty. Thanks to fencing at both the north and south ends of my property, a couple of Deerchaser battery-powered repellants, two outdoor dogs, and vibes from me, deer rarely venture on site. But, as I discovered this past summer, just one deer on just one night can do a lot of damage to a young tree.

So this year I’m putting 5 foot high by 3 foot diameter cages of 2×4 welded wire fencing around my young apple trees. Deer protection, high fenceThe pear trees, close to the house, don’t get bothered. The problem with such cages is that it’s a hassle to weed or prune within the cage — both very important for young trees. Two metal stakes, each a 5 feet length of EMT electrical conduit, woven into part of fencing on opposite sides allows me to slide the fence up and down to get inside a cage to work. These trees, which are replacing my very dwarf apple trees, are semi-dwarfs which can fend for themselves once they get above 5 feet. Then I’ll remove the cages.

Memorables, for Vegetables

And now, some notes for next season’s vegetable garden . . .

Reduce the number of pepper varieties to those that perform and taste best here: Sweet Italia,

Italian Sweet peppers

Italian Sweet peppers

Carmen, and Escamillo. And stake them right from the get go.

Plant a greater proportion of tight-necked onions, such as Patterson, New York Early, and Copra, to avoid bacterial diseases.

Plant less bok choy; no need to be inundated by them just because the space is available.

Keep an eye out for whiteflies and caterpillars on cabbage family plants; act sooner rather than later to keep them in check.

Plant more Shirofumi edemame; 30 feet of bed should be about right, they need a long, hot season.

Try King of the Garden Limas again, but plant even earlier indoors. 

Get Out!

Okay, time to get outside to work on my punch list before any snowfall limits the possibilities.

Some Fruits and a Ornamental Veggie

Happy Blueberries, Happy Me

My sixteen blueberry plants make me happy, so I make them happy. (They made me happy this year to the tune of 190 quarts of berries, half of which are in the freezer.) I don’t know how much work bearing all those berries was for them, but I just finished my annual fall ritual of lugging bag upon bag of leaves over to the berry patch to spread beneath the whole 750 square foot planted area.Blueberry fruit cluster

I don’t begin this ritual spreading until the blueberries’ leaves drop. Then, old leaves and dried up, old fruits are on the ground and get buried beneath the mulch, preventing any disease spores lurking in these fallen leaves or fruits from lofting back up into the plants next spring. Rainy, overcast summers or hot, dry summers or any weather in between — my bushes have never had any disease problems.

In past years, I did do two things before spreading that mulch. First, I spread some nitrogen fertilizer: my universal pabulum, soybean meal, at the rate of 2 pounds per hundred square feet. And second, I spread some sulfur, at about the same rate, to keep the soil acidic. After many years of mulching, the soil has built up an ample reserve of organic nitrogen — evidenced by the plants’ 2 to 4 feet of new stem growth each year. So I no longer add extra nitrogen.

With all those years of mulching, levels of decomposed and decomposing soil organic matter have greatly increased the soil’s buffering capacity for acidity. That means that I no longer have to pay such close attention to acidity, so I rarely add sulfur anymore.

Besides all these other benefit, the mulch has created a soft root run that retains moisture, just what blueberries’ thin roots really like. Fruit is borne on shoots that grew the previous season, so each year’s vigorous new growth translates into a good crop in the offing for the next year.

New York Bananas

Although the crop seemed paltry at first this year, by the time autumn came around, pawpaws were in abundance. This uncommon fruit is the northernmost member of the tropical custard apple family, and the fruit does indeed taste very tropical — a flavor mix of banana, mango, avocado, and vanilla custard — even though it’s easy to grow and native throughout much of the eastern U.S..Pawpaw, like crème brûlée

Two trees would be adequate for most households; I have about 20, just so I can learn more about them and their individual differences. That makes for a lot of pawpaws! (I test market most of them.)Row of pawpaw & black currant

Pawpaw fruits are very variable in both size and flavor even among the branches of a single tree. One year, I tried thinning the fruits to see if that would increase size of remaining fruits, as it does with apples and peaches. Pawpaw has a multiple ovary so each blossom can give rise to as many as 9 fruits. The small fruits are hard to see because they match so closely the green color of the leaves, so I didn’t thin as many as I had hoped. That said, at season’s end, fruits on thinned clusters seemed no larger than fruits on unthinned clusters.

Beginning around the middle of September, I began harvesting the first fruits. I picked some up from the ground and picked some softening ones from the trees, all of which continued through October. By putting them immediately in a cooler at 40°F, I still had good fruit into the middle of November.

Scarlet Runners

Every year I fear that at season’s end I’ll remember something I forgot to plant. This year it was scarlet runner beans.Scarlet runner bean flower

Despite the “bean” in the name, I’ve grown this vining bean, as do most people, primarily as an ornamental, for its scarlet blossoms. I occasionally eat the fat, hairy, yet delectable green beans.

Every year I collect some of the matured black and pale purple, calico seeds for replanting the following year. One year, I decided to cook up some of these seeds and taste them. Scarlet runner bean seeds are quite tasty (and, I learned prior to eating, nonpoisonous). Scarlet runner beans
 
Next year I’ll remember the scarlet runners. My yard will be aflame in scarlet flowers and, because the plant is pest-free  —  even to Mexican bean beetles — I expect to reap a bumper crop of beans.
