I’M AN INGRATE, AND RUTHLESS WITH FRUITLETS

Great Asparagus Does Not Require A Green Thumb

Not to be an ingrate or a braggart, but the asparagus some friends recently brought over for our shared dinner didn’t compare with my home-grown asparagus. Not that the friends’ asparagus wasn’t good. Theirs came from a local farm, so I assume harvest was within the previous 24 hours. Asparagus harvestBut the stalks of my asparagus are snapped off the plants within 100 feet of the kitchen door, clocking in at anywhere from a few minutes to an hour of time before they’re eaten. It’s not my green thumb that makes my asparagus taste so good. It’s the fact that I can harvest it within 100 feet of my kitchen door.

But don’t take my word for it. Research has shown that asparagus spears begin to age as soon as they’re picked, the stalks toughening and sugars disappearing, and bitterness, sourness, and off-flavors beginning to develop. Yum.

Taste is just one of the many reasons to plant asparagus. Here’s more: Deer and other wildlife leave it alone so it doesn’t need to be corralled within a fence; the ferny foliage that needs to be let grow after harvest ends in early July makes a soft green backdrop for colorful flowers; a planting can pump out stalks from the end of April till the end of June (around here) for decades.Asparagus in August

Asparagus’s two potential problems are relatively minor. The first is asparagus beetle, a beetle whose eggs, which look like black specks on the stalks, hatch into slug-like young that feed on the stalks. I keep this bugger in check by picking every single stalk — even spindly, inedible ones — every time the bed is harvested. The beetle, then, has nowhere to lay her eggs. (Not in my bed, least; she can seek out some wild asparagus here and there.) And then, at the end of the season, I cut down all the browned, ferny foliage and cart it over to the compost pile, in whose depths the adults, some of which overwinter in the old stalks, meet their demise.

No pesticides, organic or otherwise, have ever been sprayed on my asparagus, so natural predators also can do their share of making asparagus beetles a non-issue. Hand-picking beetles and larvae, which I’ve never had to resort to, is another way to keep the beetles in check. (My ducks may have a “hand” in that.)

Weeds are the other potential problem in an asparagus bed. One of the worst weeds in any bed is  . . . asparagus! Each red berry dangling from the stems of a female asparagus plant houses a number of seeds that, once they hit ground level, can sprout to make new plants. The cure is to plant an all male variety of asparagus, such as Jersey Giant or Jersey Prince.

Unfortunately, a package of an all male variety can contain a few females. So, in addition to planting an all male variety, the cure for weeds is straightforward: Weed! I keep my bed regularly weeded during harvest season, then only occasionally weeded once fronds start to make the bed almost impenetrable.

Off With The Fruitlets (Some, At Least)

The slow but steadily increasing warmth this spring has been ideal for tree fruits (not so much the rainy weather). A bumper crop of fruitlets perch on branches of my apple and pear trees. It’s time to remove most of them.

These plants are genetically programmed to set more fruits than they could possibly have the energy to ripen. Spring presents many hazards to those blossoms, including killing freezes and insect pests. So, come June, when some of these threats have passed, fruit trees naturally shed excess developing fruitlets. But not enough.

The trees’ goals are to make seeds to make new trees. The seeds are enclosed within fruits that appeal to wildlife, who then help disperse the seeds. Those fruits might be good enough for wildlife, but not for you and me. For larger and more flavorful fruits, even more need to be removed than are shed by the “June drop.” Only 5 to 10 percent of apple blossoms need to set fruit for a full crop.

So I’m spending some time pinching or snipping off excess fruitlets, saving those that are largest and most free from blemishes, with a few inches between those that are left.Thinning apples

Fruit thinning is not only for flavor. A large crop one year bodes for a small crop the following; fruit thinning evens out any feast and famine cycle. The thinning also reduces some pest problems caused by fruits hanging too close to each other.

Pros And Cons Of Bad Weather (For Humans)

The recent spate of rainy weather has been accompanied by cool temperatures, which some plants enjoy and others wait out. Peas, cabbage, kale, and radishes are having a grand old time; sweet corn and beans wait out the cool weather. Flowering alliumsThe most dramatic response has been in the delphiniums, dames rockets, and giant alliums. With cool temperatures, their colorful displays go on and on.

Asparagus doesn’t mind hot or cool weather. The cool weather does slow down spear production, which made for insufficient harvest to share the day my friends came to dinner.Delphinium at back of garden

PERENNIAL VEGGIES AND A DEAD AVOCADO

 

King Henry Was, And Is, Good

The good king has gone to seed. Good King Henry, that is. A plant. But no matter about that going to seed. The leaves still taste good, steamed or boiled just like spinach.

The taste similarity with spinach isn’t surprising because both plants are in the same botanical family, the Chenopodiaceae, or, more recently, the Amaranthaceae. Spinach and Good King Henry didn’t change families; their family was just taken in by, and made into a subfamily of, the Amaranthaceae.Good King Henry

Whatever its name — and it’s also paraded under such common names as poor man’s asparagus and Lincolnshire spinach — Good King Henry is a vegetable that’s been eaten for hundreds of years, except hardly ever nowadays. While spinach, beet, and some of its other kin have been improved by breeding and selection over the years, Good King Henry was neglected.

But the Good King, besides having good flavor, has a few things going for it lacking in spinach. It’s a perennial plant, it’s edible all season long, and it has no pests problems worth mentioning. This Mediterranean native made its way to my garden over 20 years ago, from seed I purchased and sowed. I haven’t had to replant it since then.

Which brings me to one possible downside of Good King Henry: It keeps trying to spread beyond the far corner of the garden where I originally planted it. Every spring I yank out errant plants, and eat them.

One of my favorite things about Good King Henry is its species name, bonus-henricus, making its whole botanical name Chenopodium bonus-henricus.

Another Perennial Oldie

Another perennial vegetable that I’ve enjoyed this spring is seakale (Crambe maritima), a relative of cabbage, broccoli, and kale. This also is an old-timey vegetable, one whose popularity peaked in the 18th century; Thomas Jefferson was a fan.

The origin of the name may trace to the leaves (kale-like) being pickled to bring aboard ships (the “sea” part of the name) to prevent scurvy.

Seakale, though perennial, does not spread. I started my plants from seed a few years ago, which is tricky only because the seeds have a low germination percentage. I’ve seen a few seedlings pop up a foot or so from the mother plant, which I welcome as an easy way to multiply my holdings.Seakale, blanched

Seakale tastes very good either cooked or raw, something like a mild cabbage with a refreshing touch of bitterness. Either way, blanching is needed to make it tasty, and that entails nothing more than covering it for a couple weeks or so, more or less depending on the weather (more warmth, less time), to keep out light and make the shoots more mild and tender.  I invert a clay flowerpot over the whole plant, with a stone or saucer over the drainage hole to keep light from wending its way in. Like asparagus, new leaves eventually need to be set free to bask in the sun to fuel the roots for the next year’s early shoots.

One more plus for seakale is that the plant is a beauty, so much so that it’s sometimes planted as an ornamental. The wavy, pale bluish green leaves have a silvery pallor reminiscent of the British seascape to which they are native. Later in the season, a seafoam of white blossoms rises from the whorl of leaves.Seakale in flower

I Give Up

Now for an about face, from European plants enjoying cool weather and sometimes dry conditions, to a tropical American plant. Awhile back I wrote about my efforts to grow avocados here in New York’s Hudson Valley. Not on a large scale; just one or two plants from which I could harvest a few fruits of some special variety.

I grew two plants from seeds I saved from locally purchased avocado fruits, and grafted onto those seedlings the stems of two varieties a gardening buddy sent up from Florida. Ungrafted, the seedling plants would bear fruit of unknown quality, if they bore at all. Grafted plants would give me improved, named varieties that would bear quickly.Avocado grafts

I failed. Only one graft took, yet two varieties are needed for fruiting. As expected, the grafted stem on the successfully grafted plant flowered within a year of grafting. For days I tried to get the pollen from the male to pollinate the female parts of the flower — to no avail. And then, for some reason, the grafted stem started to darken and turn black, and died back.Avocado with dead graft

I give up on trying to grow an indoor-outdoor avocado plant — for fruit — in a pot.

PERMACULTURAL GLITCHES

Imperfect Lawn

I’m no devotee of the perfect lawn, but I did recently suggest, for the bare palette of ground on which W wanted to plan for a variety of fruits, a patch of lawn. W protested that she hated mowing and wanted a “permaculture planting” that would take little care.

Visitors to my garden have occasionally complimented me on my lawn. The only care I give it is mowing with a mulching mower that lets clippings rain back down. By not cutting the lawn I avoid “mining” the soil for nutrients by repeated harvest of clippings. The clippings also enrich the ground with humus.

Pawpaw tree in my cousin’s lawn

Still, I’d rather grow trees, shrubs, vines, especially fruiting ones, and vegetables and flowers, than lawngrass. But I have plenty of ground devoted to these plants. And the easiest way to care for a plot of ground, short of sealing it in asphalt or just letting weeds grow (some of which would undoubtedly be edible or attractive) is by mowing. Visually, lawngrass also provide a calm backdrop for the scene out my back and front door. Plus, it’s nice to walk and play on.

A lawn need not be the environmental disaster inadvertently promoted by purveyors of fertilizers, and pesticides. As stated above, by letting clippings fall where they may, ground is not drained of its fertility, so fertilizer may not be needed. Especially if you let a little clover invade the lawn to add nitrogen, the most evanescent of plant nutrients.

That nitrogen highlights another approach to an easier lawn: Not striving for the uniform look of artificial turf. My lawn has its share of dandelions and clover and, later in the season, crabgrass, especially if the weather turns dry. I tolerate all this, with a refocussing of my aesthetic lens to celebrate a certain amount of diversity in the lawn.

Lawn care is even more environmentally sound these days with cordless electric lawnmowers not spewing noise, carbon dioxide, and other byproducts of gasoline consumption into the air. Periodic scything is a very pleasant way to get by with less mowing and sheep may be a way to get by with no mowing (but you do have to fence and do whatever else is necessary to care for the sheep).

Fruits To (And Not To) Grow

Now for W’s permaculture fruit trees, shrubs, and vines — with some lawn, of course. (I think I convinced her.) For starters, I suggested steering clear of apples, peaches, plums, cherries, nectarines, and apricots. All are relatively high maintenance and, even with all that maintenance, still are iffy crops in this part of the world because of our extreme and variable climate and the plants’ susceptibilities to insects and diseases.

So what’s there left to grow??!! Berries, for one. Most berries don’t stand up well to commercial handling so are picked underripe even though they don’t ripen at all once harvested — all the more reason to grow berries in the backyard where the best tasting varieties can be planted and the harvest need not be shipped much further than arms’ length.

Redcurrant espalier

Summer's berries

Raspberries, blackberries, blueberries, and strawberries are all easy to grow without much care beyond pruning, which is very important for keeping the plants disease free and convenient to harvest.

And no need to restrict the berry bowl to these most common berries. Also easy to grow are seaberries, elderberries, lingonberries, mulberries, and hardy kiwifruit (which are, botanically, berries). An added plus for these latter berries, as well as the aforementioned blueberries, is that the plants are also ornamental.

There is one common tree fruit that’s easy to grow: pears.  And even easier than European pears, such as Bartlett, Anjou, and Bosc, are Asian pears, such as Chojuro, Yoinashi, Hosui, and scores of other varieties. Asian pears also bear more quickly and prolifically, and are a little more decorative than the also decorative European pears.

Avoiding Nightmares

The main problem that I’ve seen with many permaculture plantings is that they look great on paper as well as when first planted. Mouths water at the prospects of all those ornamental, fruiting plants cozied together, fruit on creeping plants beneath trees whose branches strain downward with their weight of fruit. And perhaps a nearby grape or kiwifruit plant insinuating its berried vines in among the trees’ branches.

I’ve seen such plans and such plantings. What a nightmare of management they are or will be, mostly because of the need for relentless, extensive, judicious pruning to keep some plants from overtaking the landscape and starving others for nutrients or light. The result is less fruit of lower quality and difficulty in finding the fruit and getting to it.

A little lawn is good to give the fruiting plants some elbow room and to make them easier to care for.

GRAPE EXPECTATIONS

Hello Vanessa

A few days ago was the perfect day for planting the Vanessa grape vine deposited here by the UPS guy. Not because the weather was warm and sunny or because working outdoors was made all the more pleasant with peach, pear, and plum trees in all their glory, awash in white or pink blossoms. And not because the plums were suffusing the air with a most delectable fragrance.

Vanessa grape

The day was perfect for planting because the soil was in such good tilth. With each shovelful, clumps of soil broke apart under their own weight. A far cry from decades ago in my first garden, around this time of year, when digging brought up clods of Wisconsin soil still sticky and wet.

In wet soil, digging drives air out of the soil; under such conditions, roots of trees, shrubs, vines, and seedlings suffer. Better to wait for the soil to dry before planting. But not too long. Soil that is too dry turns rock-hard, too hard to crumble into small pieces to sift amongst roots. All this is moot in sandy soils, which never hold enough water to make them too wet for planting. Firming soil around roots

My present ground is a clay loam, which could be poor for planting if too wet. It wasn’t, because, first of all, it hadn’t rained for a few days. Second, warm weather had warmed the soil, the warmth speeding downward movement of excess water. And third, years and years of mulching with leaves, hay, and compost had made the ground rich in organic matter whose goodness had worked its way down through the soil profile with the help of earthworms and other soil organisms, rain, and the action of alternate freezing and thawing. Organic matter, among other benefits, acts as a glue to aggregate soil particles into a crystalline-like structure that helps with holding both air and water.

Training And Pruning Plans

I can bank on Vanessa growing well her first season in the ground. Soon after she arrived, bare-root, I had her roots plumping up with a day-long soak in water. Her planting hole was just deep enough to let her sit at the same depth as in the nursery, and one-and-a-half to twice the spread of the roots across. I clipped back a couple of long, straggly roots.

Holding the stem with one hand, I pushed the soil I had dug out of the hole back in amongst the roots, working it in with my fingertips after initially sifting soil in among the smaller roots by bouncing the plant up and down a little. With the roots nestled into their planting hole, I sprinkled a couple of gallons of water to further settle the soil and get the plant off to a good start.

She arrived with five strong-looking canes jutting up just above where her roots splayed out. Too many, for my purposes. Like her established neighbors, Vanessa will be trained to a “high wire double cordon spur pruned” system, a mouthful that sounds more complicated than it is. Two trunks will rise, unbranched, to about 6 feet in height to the middle wire of a five-wire trellis. One trunk will continue its journey horizontally along the middle wire in one direction; the extension of the other trunk will do likewise in the opposite direction. These two horizontal growths are permanent fixtures, called cordons (same root as the word “cord”). High wire double cordon spur pruned grape

Grapes bear fruits on one-year old stems — these are the so-called “canes,” easily identified by their smooth, reddish brown bark and roughly pencil-thickness. New shoots growing from buds on canes bear bunches of grapes and can drape on the remaining wires on either side of the middle wire.

The following year, the new shoots become one-year-old canes. Without pruning (or with incorrect pruning), fruiting shoots and canes each year move further and further away from the cordon, so I cut each cane back to 2 buds in winter and, after a few years, cut them all the way back, to be replaced by new canes that are always popping out right from the cordon.New shoots bearing grapes

But all this is in Vanessa’s future. This year, all I want from her is two strong trunks.

Don’t Do What I Did

Rain fell, and I didn’t follow my own advice. Because I needed to convert a lumpy old garden area next door to lawn, and because lawngrass establishes best in cool weather, and because I had two helpers coming in a few days to help with ground preparation, I readied the area with a rototiller. I did so even though rain had been falling all day long. Rain fell even while I was tilling.

All in all, it was a horrible experience. Mud everywhere. Wrestling the tiller. Loud engine chugging away. (Now I remember one reason for my book, Weedless Gardening. Weed-less-ness comes, in part, from dispensing with tilling, which awakens buried weed seeds by exposing them to light. And there’s the added benefit of not having to till.)

Youthful, foolish Lee, tilling

Youthful, foolish Lee, tilling

With good drainage, the job finally got done without excessive destruction of soil structure. And anyway, I was only planting lawngrass.

A BETTER BERRY?

Out With The Old, In With The New

“Doubtless God could have made a better berry, but doubtless God never did,” wrote a Dr. Boteler about the strawberry (as quoted in Izaak Walton’s 17th century classic The Compleat Angler). I disagree. I also don’t like to crawl for my fruit. With that said, I’ll agree that strawberries do taste very good, more so for being, usually, the first fruits of the season.

I just took a look at my strawberry bed; weeds are making inroads and the plants look pretty puny. Dispatching the weeds is no problem. As far as the puny plants, it was to be expected. Although strawberries are perennial plants, over time they pick up diseases, including some virus diseases lacking dramatic symptoms except that they reduce productivity. So a strawberry bed should be replanted — at a new location — every 5 years. My garden notes tell me my strawberry bed is 8 years old.

My strawberry bed in its prime

My strawberry bed in its prime

Strawberries send out shoots, called runners, at the ends of which develop new plants which, in turn, send out runners that also develop new plants, ad infinitum. So an untended bed can become very weedy, with strawberries. Even a well-tended bed sneaks in a few extra plants here and there. None of these plants should be used to start a new strawberry bed! Viruses are systemic, so all these new plants will also carry any virus infection.

I’ll be ordering my new strawberry plants from a nursery that sells certified disease and virus free strawberry plants. Then, at least, the plants start off “clean.”

The Best Berry Of All

If I had authored that quote by Dr. Boteler, I would have applied it to highbush blueberries. Not only are they, in my opinion, the best tasting berry, but the plants are truly perennial, remaining productive for 50 years or more. And I can harvest them standing up.Bunch of blueberries

No one is sure just how long a blueberry bush will thrive because they haven’t been cultivated for very long. It was only about a hundred years ago that Dr. Frank Coville of the USDA started studying blueberries in an effort to learn how to grow them. Previous to that, harvests were from wild plants. Even 50 years ago, fresh blueberries rarely appeared on grocer’s shelves.

Of Strawberries And Intrigue

Strawberries, also, have come into cultivation relatively recently, in this case over the past 200 years. Garden strawberries, that is, which owe their origin to a chance mating of two American species of strawberry in a garden in France.

One parent of the modern garden strawberry is the Virginia strawberry of eastern North America. Plants of this tasty, small-fruited species were brought over to Europe and planted in gardens there as early as the 17th century.

Intrigue enters the story in the arrival of the other parent of the modern, garden strawberry, the Chilean strawberry, to Europe. Moving the clock forward to the beginning of the 18th century, we find the French King Louis XIV needing a spy to observe Spanish fortifications in Concepcion, Chile. For this task, he chooses Amédée Francois Frezier, a young lieutenant colonel who had already distinguished himself with an aptitude for foreign languages and science. Amédée set sail on an armed merchant marine ship in 1712.

Upon his arrival in Concepcion, Chile, Amédée posed as a merchant marine captain, which enabled him to visit Spanish fortifications as a tourist. Secretly, he kept notes and made sketches of ammunition stores and escape routes. Besides military reports, Amédée also wrote about the indigenous peoples, the physical geography, and agriculture of the region. One of the plants that caught the lieutenant colonel’s fancy was the Chilean strawberry, which bore fruits larger than those that were known in Europe. Amédée included descriptions and sketches of the Chilean strawberry in his notes, and when it finally came time to leave Chile in 1714, he packed up five plants to smuggle back for his return voyage.

The marriage of the two species finally took place in a strawberry field near Brest, France as a bee carried pollen from the flower of a Virginia strawberry to the female flower of a Chilean strawberry. A seed from the fruit that developed germinated and grew into a plant that was the first modern, hybrid strawberry, combining the large size of one with the high flavor and intense red color of the other.

Better Strawberries

Since Dr. Boteler and Izaak Walton were writing in the 17th century, that “better berry” to which they referred could not have been the modern, garden strawberry. But other species were enjoyed before the modern species came into being: the alpine strawberry (Fragaria vesca), and the musk strawberry (Fragaria moschata). Both species yield delectable, though small, fruits, and are still available today. I’ve grown both.

Musk strawberry

Musk strawberry might be the best tasting of all, but yielded very little for me.White alpine strawberries

I’ve grown, and still grow, alpine strawberries, white ones that have a pineapple-y flavor and are ignored, because of their lack of color, by birds. The plants are cold-hardy, don’t make runners, and bear all season long. The fruits are a nice, little treat, but not ones with which you’d fill your freezer. For that, the one to plant is  some variety of the modern, garden strawberry. I’ll be ordering plants of Earliglow.

WITCHES AND BREBAS

Arnold, You’re Too Big

Witchhazel, a few weeks ago

Witchhazel, a few weeks ago

Over the years, my Arnold’s Promise variety of witchhazel has earned its keep with branches showered in fragrant, golden flowers late each winter. Some years, like last year, part of the bush would blossom in autumn, then put on a repeat performance in late winter. (Branches that blossom in autumn don’t blossom again in later winter, but other branches, which hold off in autumn, do.)

I should have read the fine print more carefully before I selected this variety of witchhazel. My plan was for the plant to visually smooth the transition from the corner of the house to an upright stewartia tree to a moderate-sized shrub (Arnold’s Promise) to some subshrubs (lowbush blueberry) to ground level. Except that Arnold’s Promise has grown to 15 feet high. Which it’s supposed to do, according to the fine print. Which I didn’t read.

My job, now, is to bring the shrub to more comely proportions for the site, by pruning. Like other shrubs, witchhazels can be pruned by a renewal method, cutting to the ground the oldest stems and thinning out the number of youngest stems. The pruned plant, then, always has a spectrum of various aged stems, none of them too old or too overcrowded.

What makes an “old” stem for a shrub depends on its growth habit. For raspberries, two year old stems are “old,” so old that they die. And they make lots of young stems that need ruthless thinning out.

Witchhazels are at the other extreme. Very old stems keep sporting flowers, and the shrubs typically send up very few young stems. So witchhazels need very little pruning.

Witchhazel, partially pruned

Witchhazel, partially pruned

At first, I was going to renew Arnold’s Promise over the course of a few years, removing some of the oldest stems each year and hoping for younger replacements. That would let the shrub put on a nice show each year.

But once I get started pruning, restraint is difficult. I was tempted to  cut every stem, young and old, to the ground, then decide, as growth began, which young stems to save to build up the shrub again. I mostly did that, but saved a couple of small stems for a few blossoms this autumn or late next winter.

Especially this time of year, no matter what you do, you’re unlikely to kill a shrub by pruning. And, since they’re always growing new stems from ground level, even mistakes can be eventually corrected. (More about all this in my book, The Pruning Book).

A Reprieve For Arnold

Of course, I could kill Arnold’s Promise and plant a smaller variety of witchhazel, such as Little Suzie or Pallida. The latter’s flowers are reputedly especially fragrant. Then again, it reputedly grows 10 feet high — not that much smaller than Arnold’s Promise. Little Suzie, though, is billed at reaching only 5 or 6 feet tall.

For now, I’ll try pruning to cut Arnold’s Promise down to size.

Breba Figs are Swell(ing)

I can’t leave pruning yet. Figs. These plants have a most interesting and unique flowering and fruiting habit. Some varieties bear on one-year-old stems; some on new stems; and some on both.

I was pleasantly reminded of all this as I stepped into the greenhouse and looked up at the couple of full-length stems I had left after last autumn’s pruning of San Piero fig. San Piero is one of those varieties that bears on both one-year-old and new stems. New figs, the size of a quarter were already getting plump way up at at the tippy top of the full-length stems. If all goes well, these figs — called the breba crop — will ripen in midsummer.San Piero breba figs forming

To reap that breba crop, one-year-old stems must survive winter weather. Which they do in my cool-temperature greenhouse, as well as where winter temperatures hardly dip below freezing. Where winters are cold, breba figs can be harvested from plants grown in pots and moved to a cool, but not frigid, location for winter, such as a barely heated garage or a mudroom (no light necessary). Or, in late autumn, stems can be bent to the ground and covered with plastic, to shed excess moisture, and then leaves, straw, or some other insulating material. Or, in even colder climates, bent down into a covered trench. (Fig trees are very flexible, literally and figuratively.) 

My non-breba-forming figs and all except those few long stems I left on San Piero get drastic pruning. Everything, except for those one-year-old stems to save, gets pruned down to about 3 feet high. This pruning stimulates lots of new, vigorous shoots which bear the “main” crop, in late summer and on into autumn. Unlike apples, peaches, and other familiar fruits, main crop figs keep ripening over a long period, as long as the new shoots have enough light and warmth to keep growing.

MOVING ALONG, INSIDE AND OUT

 

Figs Awakening

Even in the cool temperature (45 degrees Fahrenheit) and darkness of my basement, the potted figs can feel spring inching onward. Buds at the tips of their stems have turned green and are just waiting for some warmth to burst open. Or, if the plants just sit where they are long enough, the buds will unfurl into leaves and shoots. Which would not be a good thing.Fig bud awakening

My goal is to keep the plants asleep long enough so that they can be moved outside when they will no longer be threatened by cold temperatures. How much of a threat temperatures pose depends on how much asleep the plants are. Fully dormant, a fig tree tolerates temperatures down into the low 20’s. Even now, as they are just barely awakening, they can probably laugh off temperatures into the mid-20s.

If the buds expand into shoots and leaves, they’ll be burned by any temperature below freezing. And especially so if those new shoots and leaves get started indoors, where warm temperatures and relatively low light makes for overly succulent growth. Bright sunlight, even without freezing temperatures, can then cause damage.

Fig plants that start growing in earnest indoors get presented with two options. The first is to get them to the sunniest window in the coolest room so that growth is more robust, then move them outdoors after any threat of frost has passed — about the same time as tomato transplants get planted out. (Around here, that’s about the third week in May.)

The second option is to move them outdoors as soon as temperatures won’t again fall below the mid-20s. Temperatures below 32 will burn the succulent, new shoots and leaves, but plants will push forth new growth well-adapted to the great outdoors. If an Arctic blast is predicted, with lower that usual temperatures — that is, below about 25 degrees Fahrenheit — the plants need to be moved temporarily to the garage, mudroom, or other convenient shelter.

Different Strokes For Different . . . Figs

A fig’s treatment depends on the variety. Genoa, Excel, and Ronde de Bordeaux are three new varieties that I hope to taste this summer. They’ll get first-class coddling: Moved outside soon, then put into temporary shelter at the slightest hint that damaging temperatures could arrive. I might just put the others outside, and leave them there.Some figs of summer

The Kadota fig gets planted, in its pot, right in the ground. Its roots will grow out through all the holes I drilled in the side and bottom of the pot so the plant becomes self-supporting, waterwise, until fall. I’ll plant it out soon, even though once it’s planted, it’s staying put all season long. (I have a backup plant.)

Too Weird To Eat

Moving forward into spring — on into late spring — brings dogwoods into bloom. Blossoms of our native flowering dogwood (Cornus florida) will soon be followed by those of kousa dogwood (C. kousa), and also called Japanese or Korean dogwood), native to east Asia.

The flowers of both species are very small and pretty much green. “Not so!,” you say, thinking back to last spring’s show of large white or pink petals. Those large white or pink things are, in fact, not petals, but bracts, which are modified leaves that, admittedly, serve pretty much the same function as petals, that is, to look pretty, attract pollinators, etc.

Over the years, the spring show from flowering dogwoods has become sparse because of powdery mildew and other diseases. Which is why kousa dogwood, which is disease resistant, has been increasingly planted.

Flowering dogwood can have either pink or white flowers — whoops, I mean bracts. Until recently, kousa dogwood came only in white. But now, breeders at Rutgers University, after decades of work, have introduced Scarlet Fire kousa dogwood, a cold hardy (Zone 5 to 8), disease resistant variety bearing pink bracts.Cornus kousa fruit in summer

The flowers of kousa dogwood, whether pink or white bracted, are followed by edible fruits. The round fruits are the size of a quarter, dark pink, and very weird-looking. To me, they look like water (naval) mines, not a very friendly association for a fruit. Their appearance has also been described as that of a sea urchin shell, also not very gustatory. Inside, the flesh is sweetish and mealy, something like a cross between mango and pumpkin — not my two favorite flavors, but even if they were, those dark pink water mines are too off-putting in appearance for me to more than sample them (just so I could report on their flavor).

Still, kousa fruits add to the show from the flowering bracts and the healthy foliage.

IT’S SPRING! INDOORS, AT LEAST

One spring day many years ago, my friend Bill looked out upon the daffodils blooming and other stirrings, and summed up the scene with the statement that “It’s spring and everything is wigglin’.” We haven’t yet come that far along, but things are wigglin’ — indoors. (Little did I know that 2 days after writing this, all would be buried under two feet of snow!)

Most dramatic among the wigglins is the big, fat flower bud pushing up from the big, fat amaryllis bulb. True, the goal of most people is to have the flamboyant, red blossoms open for Christmas, which requires beginning a bulb’s dormant period in the middle of August. It’s cool temperatures, around 55°F., and dry soil that puts an amaryllis bulb to sleep. Then, in early November, warm temperatures and just a little water wakens the bulb out of its slumber, with increasing watering, commensurate with its growth, bringing the bulb fully awake and ready to burst forth in bloom 6 weeks later.Amaryllis late last winter

In mid-August, I’m more focussed on harvesting tomatoes and peppers, readying endive for October harvests, making compost, and other garden goings-on than on the amaryllis bulb that I tipped out of its pot and planted in the ground in late spring. And anyway, a few red flowers, even flamboyant ones, do little to counteract December’s grayness.

So I let my amaryllis flower in its time, which should be within a couple of weeks or so, and add to the indoor late winter wrigglin.

Citruses Come Awake

Much more exciting are the less dramatic signs of growth on some of my potted subtropical trees.

As subtropical plants, citrus trees push out multiple flushes of growth through the year. The first flush is about to begin on Meyer lemon, Golden Nugget mandarin, and Meiwa kumquat.

One or more of those citrus flushes also bears flowers, which lead to fruits. The kumquat typically flowers late. My Golden Nugget mandarin hasn’t yet ever flowered for me, so I’m not sure when to expect those blossoms. Wait! Do I see the tiny beginnings of a flower bud on that nascent stem?

Meyer lemon is notorious for its free flowering. Looking closely, I see that some of the new growth includes flower buds. At the same time, I see that the lemon fruits that had their beginnings last year are now swelling more rapidly. I’m predicting to have new lemons forming even as I am harvesting ripe ones.Meyer lemon flower buds

Fresh-picked Avocados, in New York?

Most exciting are the fat buds expanding on my potted avocado tree, grown from a seed I planted a couple of years ago. I grafted this seedling with a stem of the Marcus Pumpkin variety of avocado that I got about this time last year from a friend in Florida.

An avocado tree grown from seed would take many years — if ever, as a houseplant this far north — to reach maturity, that is, to be old enough to be able to flower and fruit. A stem taken from a fruiting plant is already mature, though, and remains so even if grafted on a young seedling. The grafted stem of Marcus Pumpkin on my avocado tree is, in fact, about to burst into bloom.

Much can happen ‘twixt the bloom and the mouth; I’m guardedly hopeful to be guacamole-ing freshly plucked avocados in a few months. The problem is synchronous dichogamy, which may end up being more of a mouthful than my avocado fruit. The upshot of this mouthful is that each of an avocado plant’s gazillion flowers stays open for 2 days. When the flower first opens it is in the female phase, receptive to pollen; this phase lasts 2 to 4 hours. Day 2 has the flower in its male phase, shedding pollen. The male and female flower parts being out of synch is good for avocado evolution but bad for me as far as home-grown gucamole.

Depending on the variety, avocado flowers might be Type A or Type B. Type A flowers are not ambitious, competitive, or impatient like Type A humans. Or maybe they are, because the female parts are open and receptive only in the morning of the first day; these same flowers open as males in the afternoon of the second day. Type B flowers aren’t ready for action until the afternoon of their first day; then they open a males the next morning.

The upshot of all this is that it’s best to have two different avocado varieties, a Type A and a Type B. The morning phase of Type B, as males, can pollinate the morning phase of Type A, which are females. And vice versa.

Marcus Pumpkin is a Type B avocado. When I grafted it, I also grafted Lula, a Type A avocado, on another seedling. Although Lula failed to take, all may not be lost. My plan is to dab the Marcus Pumpkin flowers in the afternoon with an artist’s brush, tap the pollen into a petri dish, cover it, and the next morning dab the brush from the collected pollen to the Marcus Pumpkin flowers in their female phase.

Perhaps I’ll be harvesting fresh avocados in a few months. Perhaps I’ll be just buying fresh avocados in a few months. At any rate, as a northern gardener, it’s very exciting to have my avocado tree about to flower.

And Even Hints Of Spring Outdoors

All is not so quiescent outside. After a couple of warm days, I see that winter aconites have spread their cheery, yellow petals. (But not for long.)Winter aconite

A WINTER DAY WITH SPRING IN THE AIR

Spring Dreams

Looking out a window today, all I see is white, a thick blanket of snow covering the ground and howling winds periodically puff clouds of it swirling into the air. Still, I can feel the pull of spring. Perhaps it’s the bright sunlight. Couple that with the colorful gardening magazines and catalog strewn on the kitchen table, and how can I resist vicarious planting — by ordering plants instead.

David Austin roses, whose blooms have the look and fragrances of yesteryear (pastel colors and blowsy form), and the repeat blooming of pest-resistance of presentyear roses, are always a draw. Every year, new varieties are offered, some, I’m gad to see, that are cold-hardy to zone 4.

And m–m-m-m, the thought of picking fresh, ripe sweet cherries is also enticing. No, no! I ordered and planted what was allegedly a self-fertile Compact Stella cherry tree seven years ago. It wasn’t compact and it has yet to bear a cherry. I tell others that sweet cherries are a poor bet around here because of winter cold, spring frosts, and various inset and disease pests. And, after that, even if fruits do develop, birds will likely eat them. I should have been listening when I dispensed that advice.

The cherry tree has one more season to prove it’s worth. If it doesn’t, I have a replacement plant (hardy orange, Citrus trifoliata) anxiously waiting in the wings.Hardy orange

I’ve always wanted to plant a magnolia, of which there are many newer and older varieties, but where could I plant it? Now that I think of it, I did plant a magnolia last spring. It died. And a few years back, I planted a sweetbay magnolia (Magnolia virginiana) purchased on an impulse at a nursery a few years ago. I remember planting it, but not what happened to it, except that it’s no longer around.

The magnolia that I really want to plant is southern magnolia, Magnolia grandiflora. This large evergreen gracing many homes from Virginia southward with its large, glossy, dark green leaves and it’s large, lily-white, fragrant blossoms seems to politely call for a chair in its shade, a frosty mint julep on the armrest.

Problem is that southern magnolias are not hardy here — yet. I know of a gorgeous tree about an hour south of here and two varieties — Edith Pogue and Bracken’s Brown Beauty — are hardy below zero degrees F. It hardly gets below zero here these past few winters and, with global warming . . . ?

Yes, it is hard to keep my wits about me as spring approaches, and will be increasingly so as spring edges in. “I will not buy another sweet cherry tree, I will not buy another apricot tree (even more problematic), I will not buy another magnolia (yet), . . .”

Dorris, I’d Like To Meet You

Uh oh, another new variety of filbert from the breeding program at Oregon State University. This variety, Dorris, is, like some of its recent predecessors, immune to the eastern filbert blight that has for so long made filbert growing east of the Rockies unfeasible. They’re breeding blight-resistant filbert in Oregon because the blight fungus has made its way west.

Filbert nut harvest last fall

But eastern filbert blight is a capricious fungus, sometimes changing in a way that let’s it attack even “resistant” filberts. So I’m constantly cutting down diseased filberts and replanting “resistant” ones. One of the newest varieties, which will get a spot in the line of filberts that draws my eyes and footsteps along the edge of  meadow, is Dorris.

Good luck Dorris.

Making Trees

Some trees and shrubs coming to my garden this year are going to be home-made, that is, created by me from seeds, cuttings, or grafts. To that end, I recently collected hackberry seeds as well as scions (for grafting) of persimmon, pear, and cornelian cherry, and packed them all away in an insulated box in my garage. I will deal with them in a few weeks.

Collecting scionwood for grafting segue nicely with pruning. From the prunings strews about on the ground, I cut and save one-year-old stems into foot-long sections.

THE WEATHER WON’T PUSH ME AROUND

Breaking (Pruning) Rules

Snow squall or not, I just had to get outside. Not enough snow for a cross-country ski, but, after too much time indoors, I had to do something outside.

I was driven to break a fundamental rule of the garden. I pruned, and that’s a no-no. Pruning is best delayed until at least after the coldest part of winter is over, ideally closer to the time when warmth and sun are stirring buds to swell in preparation for their final burst. I did rationalize that any pruning now would leave me that much less to do amidst the hubbub of spring gardening activities.

I wasn’t indiscriminate in trespassing this Rule of Gardening. The plants that I pruned were gooseberries, which are very cold-hardy plants so are unlikely to suffer any cold damage as a result of untimely pruning. Also, no need to wait, as is done with peaches, for growth to begin to see which branches have died back from winter cold; none ever do so on a gooseberry bush.

Pruning without spring breathing down my back made for a very relaxed pruning session. I had plenty of time to pay attention to details and prune a little differently than in the past.

Gooseberries bear fruits on stems that are 1-, 2-, and 3-years-old, so the usual method of pruning is to cut away any stems more than 3-years-old and remove all but six of the sturdiest 1-year-old stems. The pruned bush, then, is left with a half-dozen each of 1-, 2-, and 3-year old stems. Each year a bush is renewed as oldest stems are removed, and new grow kept vigorous and healthy as excess young stems are thinned out.

Gooseberry before & after pruning

The gooseberry bushes always bear many more berries than we can eat, and their weight bows the branches to the ground. So this year I decided to also prune each side branch on the older stems back to a couple of inches long. I’ll reap fewer berries, but those that remain should be larger and more accessible among the thorny stems.

Great Gooseberries

Is it worth mentioning such details about growing gooseberries? After all, who eats gooseberries these days? To most people, a gooseberry is a small, green, tart berry suitable only for pies, jams, and fools (a dessert made by folding cooked, sweetened, sieved gooseberries into whipped cream).A bowl of fresh gooseberries

If small, green, and tart is your idea of a gooseberry, you’ve never tasted a so-called dessert gooseberry. Dessert gooseberries are sweet and flavorful right off the bush; they are, as Edward Bunyard wrote almost a hundred years ago in The Anatomy of Dessert, “the fruit par excellence for ambulant consumption.” (He was from England, where gooseberries are more appreciated and known than here.)Gooseberry varieties on a bench

Only certain gooseberry varieties warrant the label “dessert gooseberry,’ of which I grow about a dozen varieties. My favorites include Hinonmakis Yellow, Poorman, Black Satin, Webster, Red jacket, and Captivator. Their sweet flavors carry wine-y overtones and reminiscences of plum or apricot. Some have soft skins, others have firm skins that explode with the flavorful, sweet juice when you bite into them. I devote a whole chapter to the history and varieties of gooseberries as well as how to grow them and where to get them in my book Uncommon Fruits for Every Garden (available from the usual sources and, from me and signed, at my website).

Back Indoors, But Still Gardening

Frozen fingertips eventually drove me back indoors. But I’m now on a gardening roll, spurred on further by a box of seed packets that arrived in the mail.Lettuce seedlings

Lettuce, claytonia, and celery from the greenhouse have been filling our salad bowls all winter. As these plants wane or go to seed, we’ll need more. So today I sowed seeds of Black-Seeded Simpson, Romaine, Buttercrunch, Blushed Butter Cos, and Majestic Red lettuces. Some I sprinkled into seed flats that can be kept warm for quick germination. Some I sowed right in the ground beds in the greenhouse; they’ll germinate more slowly but hold their quality longer than those that are pricked out from seed flats into “cells” and then into the garden.

Sometime soon, I’ll grab my pruning shears and get back to the gooseberries. And then on to the grapes, the kiwis, the apples, the pears, the . . .
