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 …

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 …

I TAKE A CLOSER LOOK, AND LIKE WHAT I SEE

 

Hey Bud, ‘Sup?

Nothing like winter to force me to take a closer look at my trees and shrubs. “To see what, you may ask?” To look at their buds, within which lie the makings of this season’s flowers and shoots. Not only are the buds quite distinctive, but they also offer a crystal ball into the future, which is very important to me as a fruit grower.

Trees’ and shrubs’ fruit and shoot buds look different from each other. It’s the fatter ones that open to become flowers and then, barring damage from late frosts, insects, diseases, or hail, fruits.

Last year, perhaps because of dry weather or a late spring freeze, my pawpaw crop was a failure. This explains why I now see so many distinctive plush, velvety, fat, brown buds — flower buds — lining the stems. For any fruiting plant, a light crop of fruit one year generally makes …

IT’S A GAS!

 Last Tomatoes & Peppers

   Late fall, and my thoughts turn naturally to . . . ethylene! You remember ethylene from high school chemistry. A simple hydrocarbon with 2 carbon atoms double-bonded together with 2 hydrogen atoms attached to each of the carbon’s remaining two free bonds. C2H4. It’s a gas, literally, and an important industrial chemical transmuted into such products as polyethylene trash bags, PVC plumbing pipes, and polystyrene packing “peanuts.”    Oh, I forgot, this is supposed to be about plants. Ethylene is synthesized in plants and is a plant hormone with — as is characteristic of hormones — dramatic effects in small amounts.    I think of ethylene as I sliced the last of the season’s fresh garden tomatoes for a sandwich a couple of weeks ago. Note that I wrote “fresh,” not “fresh-picked.” The tomatoes had been picked almost two months prior from vines I was cutting down and …

VIRTUAL TRIP TO MEDITERRANEAN

Goodbye to Figs (For Now)

   With yellowing leaves and dropping leaves, my greenhouse figs are looking sickly. But all is well in figdom. A common misconception is that figs are tropical trees. They’re not. They’re subtropical, generally tolerating cold down to near 20°F.. And their leaves are deciduous, naturally yellowing and dropping this time of year, just like maples, ashes, and other deciduous trees.    My greenhouse thermostat kicks on when the temperature inside drops to about 35°F. Daytime temperatures depend on sunlight; they might soar to 80° before awakening the exhaust fan on a sunny day in January, or hover around 35°F. on an overcast day that month. All of which is to say that the weather inside my greenhouse matches pretty well that of Barcelona and Rome, with hot dry summers and cool, moist winters. And figs grow very well in those Mediterranean climates. And go dormant.    I …

DRAMATIC PRUNING & NOT-TOO-BIG ONIONS

Henry IV Method of Pruning

   Deb get’s a little nervous every time a go into the garage for some pruning tools this time of year. Not because she’s afraid I might hurt myself but for what I might do to the plants. Today it was so-called “renovative pruning” of the St. Johnswort ‘Sunny Boulevard’ shrubs that line the western edge of the brick terrace. I approached the shrub with some unconventional pruning tools.    Let’s first backtrack and put everyone at ease. A shrub is a shrub because it’s shrubby; that is, it’s always growing new shoots at or near ground level rather than developing a permanent, upright trunk off which permanent limbs and new shoots grow. Some shrubs — most shrubs, in fact — get congested with too many new and older shoots rising from their base and too many old shoots that no longer perform well, in this case …

MANURE ABSOLVED, PRUNING STARTED

Horse Manure: Not Guilty, So On To Pruning

    A dark cloud no longer hangs over my horse manure, that is, the horse manure that I occasionally truck over here to add to my compost piles. I wrote a few weeks ago about the possibility of herbicide that, when applied to hay, retains its toxic effect when an animal eats the hay and even, for a long time, after that animal’s manure has been composted or spread on the ground.    My herbicide residue concerns were soothed with a simple assay that showed satisfactory growth from bean seeds in both hay that was suspect and hay of known integrity. Also, the bedding in the horse manure is mostly wood shavings rather than hay.    But another ugly dragon kept raising its head above the manure. Another chemical, this time, Ivermectin, a de-worming medication given to horses (and other animals). Ivermectin or its metabolites …
