LIBERATED, AT LAST

Exposée

My garden was liberated yesterday, the soil freed at last. That’s when I peeled back and folded up the black tarps that had been covering some of the vegetable beds since early April. My beautiful soil finally popped into view.

Covering the ground was for the garden’s own good. “Tarping,” as this technique is called, gets the growing season off to a weed-less start. The black cover warms the ground to awaken weed seeds. They sprout, then die as they use up their energy reserves which, without light, can’t be replenished and built up. (I first learned of this technique in J. M. Fortier’s book The Market Gardener.)

Tarping is very different from the much more common way of growing plants in holes in black plastic film, even if one purpose of the soil covering, in both cases, is to snuff out weeds. Black plastic film is left in place all season …

Keep on Composting

One Problem in Cold Weather

I don’t let cold weather put the brakes on my composting, at least my role in it. For the bacteria, fungi, and other workers in my compost pile, it’s another story. Come cold temperatures, and their work come screeching to a halt or near halt (which depends on the degree of cold, the size of the pile, the mix of ingredients, and moisture).

But that’s no reason for me to abandon composting.

The main problem, as I see it, with composting in winter is not the workers not working. Pile up food scraps another organic materials winter, and composting will re-convene when warm weather arrives again in spring. The problem is that those food scraps offer a smorgasbord of tasty, easy calories for rodents. Which is not good.

(Lest you’re feeling fuzzy and warm to these furry creatures, a short list of what they could bring along to you …

What Midwinter, Spring-like Weather Will Do

My Garden’s A Mess!

After some really frigid weather a month ago followed by more or less seasonal cold, temperatures did a loop de loop and we’ve had a couple of days in the high ‘60s. Very unseasonal, to say the least, and perhaps another indication of global warming, but welcome nonetheless. Those temperatures, coupled with brightening sunshine, made me want to get my hands in some dirt.

A large, second-story bedroom window overlooks my main vegetable garden. The weather made me see it in a different perspective — it looked messy. 

I pride myself on putting everything in order each fall so that (quoting from Charles Dudley Warner’s 1886 My summer in the Garden) “The closing scenes are not necessarily funereal . . . A garden should be got ready for winter . . . neat and trim. . . in complete order so that its last days shall not present a …

MORE AUTUMNAL NEATENING

An Upbeat Closing

I don’t know about you all, but I have a great urge to tidy up my garden this time of year. Partly it’s because doing so leaves one less thing to do in spring and partly because, as Charles Dudley Warner wrote in My Summer in the Garden in 1889, “the closing scenes need not be funereal.” All this tidying up is usually quite enjoyable.

Moist soil – and not too, too many weeds – make weeding fun. Creeping Charlie (also know as gill-over-the-ground) has sneaked into some flower beds. Its creeping stems are not yet well-rooted so one tug with a gloved hand and a bunch of escaping stems slithers back from its travels forward from beneath and among flower plants and shrubs. What remains are occasional tufts of grassy plants, especially crabgrass, easily wrenched out of the ground or coaxed out with my Hori-Hori garden knife.

This tidying …

A MONTH OF RECOGNITION

Good in the Lab

National Fruit Fly Month — October — has drawn to a close. (That designation is my own, not the federal government’s.) Sure, a few still flit about here and there. But no longer do clouds of them hover over bowls of fruit in my kitchen. In case you haven’t experienced them, fruit flies, Drosophila species, are cute little (about 1/8 inch long) flies that feast on overripe and damaged fruit as well as other plant material.

I, and perhaps you, were first introduced to fruit flies in middle school biology, raising them on some mix of banana and agar-agar. In those days, I got more intimate with them as part of a science project: My project was to test whether x-rays cause mutations. My dentist agreed to help. After raising a batch of flies, I went to his office and laid a vial of them on the dental …

Battle for Figs: Victory

Some History

I don’t know the score over the years, but this year’s victory is mine. The battles have been with scale insects, both armored scales and their cousins, mealybugs (but rarely both in the same year), on my greenhouse fig plants.

Those fig plants are planted in the ground in a minimally heated greenhouse, where winter temperatures can sink to about 35°F. The oldest of these plants have trunks 8 inches in diameter. They thrived for years without any pest problems, scale of otherwise. A few years ago, the insects made their appearance, sometimes ruining almost the whole crop.

Over the years I fought them in various ways. One year it was spraying the dormant plants with alcohol. Another year it was, more aggressively, scrubbing trunks and stems of dormant plants with a toothbrush dipped in alcohol. Ants herd and protect scale insects, so another year I fenced the ants off the …

Interesting and Fun

Interesting, But I Could Do Without It

Out doing stuff in the garden, I sometimes wonder: What’s fun about gardening? What’s interesting about gardening?

European hornets are interesting. My first encounter with them — large, intimidating looking hornets with fat, yellow and black striped bodies, was a few years ago when I saw it feeding on kitchen trimmings as I was about to add more to the compost pile.  

The thought of a sting from this brute seemed horrendous; I learned, though, that they’re not particularly aggressive and their sting belies their ferocious look. The menacing-looking brute that entered the schoolyard turned out to be a pretty nice guy.

My next significant encounter with European hornets was this week, as I was gazing up into the branches of my plum tree admiring the ripe, red plums, ready for harvest. Reaching up and picking a fruit left me in hand with hardly more than …

Pests Pesky and Not So

Memories

The tumbled over Red Russian kale seedling brought back old memories. It was like seeing the work of an old friend — or, rather, an old enemy. It’s been so long since I’ve seen a cutworm at work in my garden that I couldn’t even get angry at it.

Cutworm and friend’s broccoli

I scratched around at the base of the plant to try and find the bugger. Too late, fortunately for him or her because its fate would then have been a two-finger crush. The cutworm in a friend’s garden I visited last spring was not so lucky.

The bad thing about cutworms are that they chop down young, tender seedlings. At that age, seedlings’ roots lack the energy to grow new leaves; the plants die. (I wonder how the cutworm benefits from lopping back the seedling; the felled plant usually doesn’t get eaten.)

Inside and Outside

Houseplant Envy

I wonder why my houseplants look so unattractive, at least compared to some other people’s houseplants. I was recently awed by the lushness and beauty of a friend’s orchid cactii, begonias, and ferns. I also grow orchid cactii and ferns, so what’s with mine?

Perhaps the difference is that other’s houseplants have a cozy, overgrown look. Mine don’t. Most of my houseplants get repotted and pruned, as needed, for best growth. Every year, every two years at most, they get tipped out of their pots, their roots hacked back, then put back into their pots with new potting soil packed around their roots. In anticipation of lush growth, stems also get pruned to keep the plants from growing topheavy.

Rather than being scattered willy-nilly throughout the house or clustered cozily in corners, as in friends’ homes, my houseplants get carefully sited. For best growth, plants, especially flowering and fruiting plants, need …

Dry, Wet, Bad, Good?

Some Bad

Wow! What a gardening year this has been. Looking back on 2018, it’s been the oddest year ever in terms of weather, insects, and disease.

After starting off the season parched, seemingly ready to go into drought, the weather in July did an about face. The rains began. Average precipitation here in the Northeast is about 4 inches per month. July ended up with about 6 inches, August saw 5 inches, September 8 inches(!), October 5 inches, and November 8 inches(!!).

All that rainfall brought humidity, which might have been responsible for my celeriac plants hardly growing, then rotting.

Celeriac, early in the growing season, before the rains

(Perhaps not, because this was my third growing season of failure with celeriac.) I’m taking this as a celeriac challenge. Perhaps next year I’ll try them in a large tub where I can have more control over soil composition and moisture.

The humidity also …
