SOIL PREP

Universal Plant Needs

Although garden plants hail from all corners of the world, they have surprisingly similar soil requirements — best attended to before planting. Simply put, most garden plants need soils that are well-supplied with air (yes, roots must breathe!), water, and nutrients. And one other important ingredient, organic matter (sometimes called humus), that witch’s brew of living and once-living organic materials in various states of decomposition that, in addition to contributing to the just-mentioned needs, also includes a friendly microbial community for optimum plant health.

Aeration must be the first consideration, since plants are unable to utilize nutrients, even in fertile soils, if roots lack access to air. There are two causes for waterlogged soils: either the water table is too high, bringing water up from below; or the soil has pores so small that they cling by capillary action to too much water that falls from above.

Deal with a high water table by either choosing another site for planting, by raising roots above the water table, or by lowering the water table. Growing plants in raised beds is the way to bring roots above a water table. Raised bedsBuild beds high enough to take the roots up out of the water, and wide enough so they don’t dry out too quickly. Read more

CLEAN APPLES, EDIBLE APPLES

Popular Though They May Be . . .

Apples may be a common fruit, second worldwide and in the U.S., bested only by bananas, but they surely are not the easiest ones to grow. At least not over much of this country east of the Rocky Mountains, and here on my farmden. Throughout this area, insects and diseases are ready to pounce on virtually every unsuspecting apple tree.

Pesticides will control these pests but, if needed, are effective only if used rigorously: trees must be regularly and thoroughly doused with the correct material, used at the correct concentration, and applied at the correct times. No wonder the average gardener is daunted at the thought of growing apples!

RDS (ROSEMARY DEATH SYNDROME) SOLVED?

Lack of Water Could Be the Cause

Looks like I’ve done it again. Killed rosemary, the plant. Worse than that, I’ve killed two rosemary plants. And even worse still, drawing on my experiences killing numerous rosemary plants — perhaps you also have killed one or more — I’ve been dispensing my “expertise” on how not to kill rosemary.Rosemary with winter background

My reasoning went like this: Although native to the generally dry climate of the Mediterranean region, roots of rosemary plants in the ground there can reach far and wide in their explorations for water. Not so for rosemary plants that need to live in pots here, where winters are too cold for them outdoors.

To make matters worse, rosemary’s stiff, needle-like leaves don’t signal that the plant is crying out from thirst by wilting. Read more

PLOTTING ALONG

Possible Sources of Anxiety

Especially in years past, I would get a little tense this time of year, because sometime soon I would have to sit down and map out the year’s vegetable garden. As usual, ideas have been bouncing around inside my head for the past few weeks, but the day must come — before April 1st, my date for planting peas — when procrastination must bow to action.Vegetable garden with trellis

When that time comes, I gather together on the kitchen table printouts of the empty beds in my two vegetable gardens, a sharpened pencil, and notes and plans of gardens past. After taking a deep breath, my first order of business, planning for crop rotation, begins. The theory: Plant no vegetable in the same spot sooner than every third year. The rationale: A garden pest might survive the winter to bother the same plant the following year . . . unless the plant happens to be growing elsewhere, in which case the pest starves and dies.

Pests usually are equally fond of all plants in a plant family, so I won’t grow tomatoes, peppers, eggplants, or potatoes (nightshade family) at the same location without waiting three years. Read more

HAPPY BIRTHDAY GEORGE

Was He a Bad Boy?

Washington’s birthday is a proper time to think about cherry trees. Rather than question whether or not George did chop down the tree, and whether or not he had the honesty to admit to the act, I wonder what kind of a cherry it could have been. (The story, incidentally, is apocryphal, having been fabricated by Mason Locke Weems for his 1802 book, Life of George Washington; With Curious Anecdotes, Equally Honorable to Himself and Exemplary to his Young Countrymen. “Parson” Weems also wrote of Washington throwing a silver dollar across the Delaware River).

That cherry tree could very well have been something akin to the sweet cherries we can buy or grow today. Sweet cherrySweet cherries (Prunus avium), sometimes called bird cherries or, in their more wild state, mazzard cherries, were amongst the plants ordered from Europe by the Massachusetts colony in 1629. By 1650, there was a cherry orchard in Yonkers, New York, and before the end of that century, there were plantings in Rhode Island, Maryland, and Virginia. Trees became so abundant that in 1749, Peter Kalm wrote that “all travellers are allowed to pluck ripe fruit in any garden which they pass by, provided they do not break any branches; and not even the most covetous farmer hindered them from so doing.” So it is not unlikely that Papa Washington had a few sweet cherry trees planted at his farmstead along the shores of the Rappahannock River.

That abundance of cherry trees and cherries is interesting because here in the Hudson Valley, in Eastern US in general, sweet cherries are not an easy crop. Read more

OUT TO PRUNE, WITH WHAT?

Pruning (Book) Perks

One perk of writing a book about pruning (The Pruning Book) is that, in the months after publication, I kept getting gifts in the mail, gifts in the form of pruning tools to try out. The pruning shears hang on a row of wooden pegs near my back door, loppers hang on pegs in the garage, and hand saws fill a five gallon bucket. All the big-name brands are represented, from ARS to Bahco to Corona to Felco to Fiskars to Silky. With many models of each brand of tool at my fingertips, it’s easy to know which ones I like the best. They’re the ones for which I reach most frequently.Pruning shears hung up

With the coldest part of winter behind us (and even that not very cold), it’s time for me to start pruning. A sunny day with temperatures in the 40s makes pruning an enjoyable excuse to be outdoors. Into my leather holster, which came with the shears, goes my ARS hand pruning shears. Sometimes, if I need to cut stems that are a bit beefier, I’ll grab instead my Felco shears. Or, for lighter pruning, my Pica shears. Those are my three favorites. All are excellent although the ARS shears have the edge for me.

But that’s me. As they say, “Your results (preferences) may differ.” Read more

FRUITFUL THOUGHTS

Watch for Road Blocks

If you’re considering growing fruits, good idea. You’re probably dreaming about, in a few years, being able to reach for a ripe red apple, a peach, a cherry, or a plum from a fruit laden branch. To a large degree depending on where you garden, you could be paving the way for disappointment. Insect and disease pests, and specific pruning needs, are potential road blocks for many of the more common fruits. Peach fruit on branch

Yet, luscious fruits plucked from a backyard plants are such a delicacy. What else but a fruit could have tempted Adam and Eve? Fortunately, many fruits need only a minimum amount of care. What follows are easy-to-grow fruit plants, grouped into three categories, from the very easiest to the “hardest easiest.”

Easiest Peasiest

The first category includes plants that you merely set in the ground, then come back in a couple of years for the first of many years of harvest. Well, almost nothing else to do. You may recognize in this category some plants commonly grown as ornamentals. Read more

THE GARDEN IN WINTER

Forming Relationships

This may sound crazy but even this far north, winter isn’t a bad time to admire the garden. With leaves and flowers a memory of the past season and a hope for the coming season, the garden is reduced to its bare bones. Not that the wintry scene need be dull or bleak. Good bones give structure to the landscape, knitting it together in some places, dividing it up in others, framing vistas, and providing firm footing for the eyes (figuratively) and feet (literally). Even now.

Three-dimensional forms are what give structure to a landscape. A house usually is the most obvious mass jutting up into space on a property. Too often it’s the only structural element, feebly tied to the landscape with some gumdrop-shaped junipers or yews standing, as if guarding, the foundation.

Winter view from indoorsI have effected a relationship between my yard and my house by building a grape arbor out from the rear wall, then enclosing the ground beneath this arbor with a brick terrace (my house is also brick) edged with a low hedge of potentilla. Similarly, the stone wall supporting what previous were slopes at the front and side of my house flow into the landscape with a contiguous stone wall sweeping out across the yard. Read more

ORANGES IN NY’S HUDSON VALLEY, OUTDOORS

Frightening, Beautiful, Edible

Right now, my hardy orange tree might look at its finest, standing at the head of my driveway against a pure white, snowy backdrop. An orange tree!? Outdoors with a snowy backdrop?! Okay, in all honesty, it’s a bush, not a tree. But it is an orange plant, and it does survive into Zone 5 outdoors. (Temperatures plummeted to 2° F a week ago, and coldest temperatures typically arrive around the end of this month.)

Botanically, the plant was Poncirus trifoliata. I write “was” because a few years ago, this citrus relative was welcomed closer into the citrus fold, with a new official name, Citrus trifoliata. Not all botanists recognize this closer kinship, and insist on keeping the plant in the Poncirus genus.

The kinship of hardy orange with other citrus is obvious from its glossy, forest green leaves, the sweet (but very slight) aroma of its flowers, and its fruits, which are pale orange. Poncirus Flying Dragon with fruitsThe fruits are edible but I wouldn’t bite into one; the flavor is orangish, but also sour and bitter. Perhaps I’d squeeze the pulp to add a hint of citrus flavor to some other cooked fruit or a baked good. Perhaps not.

What I like best about this plant are its stems, which are most evident now, when bared in winter. Read more

GARDEN FRESH, STILL

Good Only in Theory?

The idea has merit: flowerpots of flavorful herbs decorating windowsills and providing savory additions to meals through the winter. A good part of last season’s garden is packed in the freezer and glistening jars of canned tomatoes line shelves in the basement. The greenhouse is offering a steady supply of lettuce, arugula, and other salad greens.Rosemary against a snowy backdrop

Still, I’m beginning to miss garden-fresh vegetables. Sprinkling some fresh chives on a pan of roasted potatoes might infuse the whole dish with freshness.

The problem is that chives doesn’t thrive on a windowsill, unless the windowsill is very, very sunny. Chives will grow well through the winter with artificial light, but that means a bank of lights permanently poised a few inches above the leaves — so much for the rustic charm of indoor potted herbs. And maybe my taste buds are dulled, but when I snip chives to add to a dish, I take a handful. The plant would need at least a few weeks to recover sufficiently to withstand another harvest.

The same could be said for growing parsley indoors; after each picking, you have to wait too long for another.

I haven’t thrown up my hands at the possibility of growing culinary herbs indoors through the winter. I just have to be very selective in what I grow. Any such herb must pack a lot of flavor into each leaf, survive well indoors, and look pretty. I offer at least two candidates: rosemary and bay laurel. Read more
