Spiders and Flies and Cows, Oh My!

It is that time of year when gardeners, plants-in and waiting, are beset by bugs. I live next door to a dairy. Dairies attract flies. (Let’s not go there. It’s enough to say, it’s about the cows.) Flies attract spiders. I live in what must be the spider capital of the universe. If I don’t “sweep” or power-wash my house a couple of times a year, it looks like the wicked witch of the west lives here. The entire shadow area under the edge of the clapboards is completely filled in by spider webs. The eaves are, well, scary. My car is home to countless arachnids as well, and gets so covered in fly specks that people comment when I go into town. While I’m not fond of spiders, living here has helped me put them in perspective. At least they help keep the bugs (flies!) in check. Our plethora of insects also feeds an enormous number and variety of birds. Hey, I’m looking on the bright side here.

At about this time every year we get The Invasion of the Leaf Hoppers. They’re after green, anything green. Wave your hand over my radishes and you’ll see a cloud of them. As the green dries out of the surrounding landscape, gardens are left to absorb the bugs from everywhere else. This past week the valley farmers cut and bailed the last of the hay from the bottomlands. The hills are golden and dry. All those bugs are on the move—looking for their next meal.

It would be easy to panic and reach for a chemical solution. I think it would also be a mistake. Organic growers have options for a real emergency, but the basic framework calls for patience. Over time, the mantra, feed the soil not the plant, should lead to soil and plants healthy enough to endure the annual onslaught. This is a natural, seasonal event and agriculture over the centuries has survived pests. I guess I can, too.

Left to their own devices, plants are not defenseless against insects. When insects nibble (or chomp), plants respond chemically by making their leaves a little more bitter. It’s not so much that we’d notice (though I have tasted some overly stressed and, resultingly bitter, greens in my time) but enough to dissuade the bugs. It takes a little time. I know that when the leaf hoppers first arrive, it looks like an emergency. Hold off! Don’t reach for sprays or toxic powders. Let the plants do their magic. (The same can be said of white flies—though with them I’m inclined to reach for the Safer Soap earlier on.) You can help. Make sure they have enough water, especially if it’s hot. One year I fed my garden manure tea, but I can’t say if it was any more effective than water—but I felt better. Probably with that little extra bit of care the vegies will be just fine.

Of course, from time to time there are infestations that threaten the survival of the garden, or maybe just one of your crops. The watchword there is Know Your Bugs. We do have natural methods for most pests. For larger marauders, there’s hand-picking. This is not for the squeamish for faint of heart. It is very effective, particularly for slugs, snails, caterpillars (especially those amazing tomato hornworms, which you can feed to your chickens) and squash bugs (which I always thought was an imperative command.) These larger pests can do damage quite quickly—a tomato hornworm can defoliate a plant in days. I just squish them in my fingers, which makes the kids on the farm recoil in horror. You can also throw them in soapy water, or gently relocate them to a different environment (yeah, right.) Check the undersides of leaves for eggs, which you can squish, or wash off (or spray) with soapy water. With squash bugs, if you stay on it early in the season, you may solve your problem early on. In any event, make sure you exterminate them at the end of the season (they’ll congregate on the last remaining squash and pumpkins, or their leaves) or you’ll see them again next year. In a bucket-garden, handpicking pests is easy. When you fill the bucket reservoir, they all head up the plant for high ground. And there you are, waiting…

For little winged critters, there’s soapy water spray, both for them, their larvae and their eggs (in particular watch for those voracious cabbage moths and their larvae—sure they look like pretty white butterflies but they can do real damage.) For crawling critters—especially at the seedling stage, there’s diatomaceous earth. And if things are really bad, you can treat with Bt (bacillus thurengensis)—the organic gardener’s ace in the hole. Probably you won’t need most of these tactics.

The internet is an incredible resource, both in identifying the pest of the moment, and in suggesting treatment alternatives. Check there first, before resorting to the hardware store.

I have spiders in my garden, too. They are honored guests. I try to water and weed without disturbing them. They are my plants’ guardians. My family will be surprised that I have made my peace with spiders. From arachnophobe  to arachnophile in just a few short garden seasons.

Now if we can just do something about the gophers.
