THE DARKER SIDE OF TINKERBELL

They’re Cute, Though

The bugs is comin’! The bugs is comin’! Just as sure as the sun is rising higher in the sky each day, the hope of spring is awakening all sorts of pesky little buggers on houseplants. One by one, they are showing their faces: mites, aphids, mealybugs, scale insects, and white flies.

I’d actually consider whiteflies — the target of today’s hunt — to be cute if they weren’t plant pests. The same surely could not be said for drab mealybugs and scale insects, or for mites, the latter because you can hardly see them at all.Whitefly Read more

MOUSEY THREATS AND SOLUTIONS

/4 Comments/in /by

Food and Lodging

Mice have been seeking bed and board, all to the detriment of us gardeners. Already their devilish deeds are evident in the gnawed bark at the base of a poor little apple tree that I planted in spring.

There are a few kinds of mice, and the meadow vole (Microtus pennsylvanicus) — also known as the meadow mouse or field mouse — is most at home in tall grass. There, this rodent finds food and a place to nest and scamper about shielded from the hungry eyes of hawks, owls, weasels, skunks, and other predators.

Unfortunately, from fall to spring, meadow voles like to supplement their usual diet of grasses and herbs with the bark of trees. My trees! Your trees!

Inhospitality

The first line of defense against meadow voles, then, is to create an environment inhospitable to them. Read more

WHAT’S UP WITH TOMATOES?

Hurry Up

I’ve been enjoying tasty nuggets of Sungold tomatoes for a few weeks, and hope very soon to finally settle back to enjoy an abundance of large, juicy, red or orange tomatoes, the varieties at their best sliced and sandwiched,along with congenial companions, between two slices of bread. Those large tomato fruits are late in ripening this year.Tomatoes, still green

The problem, like lots of garden issues, can be blamed on the weather. Ideal temperatures for ripening tomatoes lie between 70 and 75 degrees F. Read more

Garlic mustard leaf

MY BRIEF AFFAIR

/2 Comments/in , , /by

What Could Be Bad?

Like most brief affairs, this one ended without rancor. A friend had introduced me to garlic mustard (Alliaria petiolata), our meeting coming at a time when I could look fondly upon any wild edible plant. That was many years ago, yet after a few years tensions between us escalated. 

In retrospect, I can’t really understand the attraction I had for garlic mustard. True, the name was appealing: you would think that any plant combining the flavors of garlic and mustard would have elicited affection that would linger, even grow, over the years.Despite the enticing name, I can now reminisce with a clear mind and remember finding the taste ho-hum at best, biting at worst.Garlic mustard

SOAP UP

Plus Ça Change . . .

In gardening as much as anything else “the more things change, the more they stay the same.” In 1845, Andrew Jackson Downing, famous horticulturalist (and native son to New York’s Hudson Valley) that a “wash of soft soap is very good for many purposes . . . penetrates all the crevices where insects may be lodged, destroying them.”Vintage ad for sprayer

Savvy gardeners were using soap sprays even back in the 1700’s, and they were continuing to do so right through the beginning of the 20th century. Read more

Ladybugs on leaf

WHERE’S HOME?

Migration

“Ladybug, ladybug fly away home…” Whoops, she did! And she’s made my home, and perhaps your home, her home. With spring just around the corner, she’s awakening and coming indoors.

Ladybugs are such lovable creatures that we — or I, at least — can’t call them a pest even when they act like one. Just now they’re creeping on windows along with cluster flies, also benign creatures but “pests” not at all welcome in my home. Ladybugs do get even peskier indoors: I occasionally find them marching across a pillow just before I lay down my head or scuffling along the edge of a teacup just before I take a sip.Madonna in the Meadow

It’s not your imagination that the annual ladybug migration indoors has increased from years’ past. Read more

CAT NIPPING, NOT SO GOOD

A Nonsymbiotic Relationship

Cats like houseplants, but houseplants don’t particularly like cats. Or, at least, cats don’t do houseplants any good.

Cat at window

Take my ponytail palm, for example. My cat is an outdoor cat, but I know if she came indoors, what a grand time she’d have jabbing her claws playfully at the ends of the ponytail palm’s wispy leaves. She’d do the same for my orchid’s flower stalk, now weighed down with a row of delicate blooms. Either plant would emerge from such play worn and frayed.

There’s not much you can do once a plant catches your cat’s fancy, except Read more

Yellowjacket

A GARDEN PEST OF HUMANS

Yellowjacket Frenemies

Not all garden pests attack plants. One pest, not of plants, that especially bugs me around this time most years is yellowjackets. Yellowjackets can be worse than irksome; they can be deadly to people allergic to their sting.

Whether deadly or just irksome, yellowjackets are amongst the orneriest of creatures. They are aggressive and, unlike honeybees, don’t have to stop after one sting. Burying its stinger in your arm has no effect on a yellowjacket’s mortality, so it can do it again if it so pleases or go on to seek out other victims.Yellowjacket

As with all of Mother Nature’s creatures, yellowjackets are not all bad — even from the biased viewpoint of us humans. Read more

Rhizoctonia damping off

DAMN-PING OFF

Worse than Roman Warriors

I made my first gardening enemies decades ago, within a few weeks of starting my first garden. Not other gardeners but — and perhaps you also have crossed paths with them — with Pythium, Rhizoctonia, and Fusarium. I quickly learned that they were, or should be, hateful not only to me but to all gardeners.

Pythium, Rhizoctonia, and Fusarium are not ancient Roman warriors; they are fungi and, worse than Roman warriors, they lurk everywhere. When they, or one of them, gets the upper hand they cause damping off disease.Beet seedling damping off

Let’s return to my first garden: At the time, decades ago, I was living in a relatively dark apartment, a converted motel room, and was eager to start my first seedlings. I sowed all sorts of seeds in peat pots, stood them in a little water, then crowded them together on all the shelf space that could be mustered.

Young sprouts never appeared in some of the pots. In others, seedlings emerged, then toppled over, their “ankles” reduced to a withered string of rotted cells unable to support the small plants physically or physiologically. Read more

Spreading wood ash

OCCULT PRACTICES?

Potash Kalium Connection

I wonder if my neighbors suspect that I’m engaging in some sort of occult ritual as I take rounds through the farmden followed by puffs of grey smoke. Perhaps I’m entreating tiny gnomes living within the soil to keep weeds at bay next season? Or begging garden gremlins to make my soil fertile? No, and again no! I’m merely spreading wood ashes.Spreading wood ash

I must be careful with my terminology: I’m not dumping wood ashes; I’m fertilizing my soil with wood ashes. Wood ash is a rich source of potassium, a nutrient required by plants in amounts second only to nitrogen. Potassium helps build strong stems and helps plants resist disease. It also regulates the opening and closing of stomata, the tiny pores in leaves through which gases pass for photosynthesis.

The close connection between potassium and wood ash is reflected in a traditional source of, and the root of the word, potassium — “potash.” Read more
