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

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.

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 …

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 …

The Best Winter Herbs

Mini-Trees for Flavor

Second best to fresh-picked vegetables in winter, which are not within most gardener’s grasp with temperatures in the single digits, are fresh-picked herbs. Fresh-picked herbs — indoors — in winter are within the grasp of most gardeners, even non-gardeners.

Flowering and fruiting demand lots of light energy, but it is the leaves of most herbs that provide us with flavoring, so most herbs do fine in any reasonably bright window. The same goes for normal household temperatures and humidity.

So make space near your windows for herb plants!

Let’s look below ground now. Any potting mix suitable for houseplants will also be to the liking of herb plants. The mix should hold some moisture between waterings while at the same time drain well so that roots, which need to breathe, don’t suffocate. My own mix, made  from equal parts compost, perlite, peat moss, and soil, provides air and moisture as well …

Fruit, Again, With Nod To Michael Jackson

Blackcaps Redux, This Season

I took a cue from Michael Jackson today when pruning my black raspberry (a.k.a. blackcap) plants. Not that I had to prune them today, or even this time of year. But I couldn’t stand looking at the tangled mass of thorny canes. And, more importantly, the tangled mass would make harvest, slated to begin in a couple of weeks or so, a bloody nightmare.

(Most blackcaps bear only once a year, in early summer, so tidiness would be the main reason to prune conventional blackcaps now. Pruning would also let remaining canes bathe in more light and air, reducing the threat of diseases. My blackcap plants, though, are the two varieties — Niwot and Ohio’s Treasure — that bear twice a year; hence, my pruning now to make picking the soon-to-ripen second crop less intimidating.)

All blackcaps have perennial roots and biennial canes. Typically, the canes just …

BLACKCAPS AND PRUNING

Blackcaps All Season (Almost)

It’s a bumper year for blackcaps (also know as black raspberries or, botanically, Rubus occidentalis), at least here on the farmden. Up to last year, we harvested wild blackcaps from plants that pop up at the edges of woods. The current bountiful harvest is from blackcaps that I planted a couple of years ago. Last year’s harvest was unimpressive because the plants were still settling into their new home.

Most blackcaps, like many other bramble fruits, have biennial canes that grow stems and leaves their first year, fruit in early summer of their second year, then die back to the ground. (Annual harvests are possible because while those second year canes are fruiting and then dying, the perennial roots are pushing up new canes, which will bear the following year.)

Niwot and Ohio’s Treasure, the two varieties I planted, stand out from the crowd in bearing on new, growing …

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. But 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 …

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.

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 …

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 …

WITCHES AND BREBAS

Arnold, You’re Too Big

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, …

BLEEDING PLANTS, WHAT ABOUT RABBITS?

 

Bleeding Is Okay

Everyone wants to prune this time of year. And rightly so. It’s a good time to prune most trees, shrubs, and vines, as it was a couple of months ago and, looking forward, will be until about when these plants come into bloom.  Or, finished blooming, in the case of those plants whose pruning gets delayed until after we all get to enjoy their early blossoms.

A reader wrote me about her Japanese maple, which needed to have one of its multi-trunks cut off. Should she do it now or in autumn? If lopped back now, would the tree bleed to death? Would the gaping wound get infected, possibly leading to the demise of the whole tree?

Bleeding sap generally does more harm to gardeners’ psyches than to plants’ physiologies. My grape and hardy kiwi vines bleed when I prune them this time of year, with …
