I’m not an organic gardener. I sprinkle fertilizer around, spray for pernicious weeds, douse a bug here and there… I figure “progress” has to be good for something more than shorter winters and a warmer globe, plus I like cool things like antibiotics, vaccines, and diabetes and heart medicines. Unfortunately, there are a few things which scare me and I’ve been thinking more and more on them lately. The most recent is the death of this year’s tomato plants.
For all the neglected vegetables of the potager, sauce tomatoes are always in demand and always harvested. The kids might throw cherry tomatoes around and play baseball with a zucchini but the paste tomatoes always find their way to the saucepan or freezer, and if it were up to me they’d all go towards pizza, not sauce, but now I’m getting distracted. This year the plants went in early, the stakes before they were needed, all were watered, mulched, and looked great… for a little while.
I mulched with lawn clippings like I always do and within a few days the plants were dying.
I take care of the lawn next door, and my mother in law always reminds me every year to put down grub killer and something for the weeds. I usually “fib” and say sure and things are just fine, but this year the clover and dandelions were getting a little too obvious, so rather than explain how the stuff ‘doesn’t always work 100%’ got a bag of Scott’s weed and feed to spread around. It worked for the most part, we’re back to a monotonous yawn and she seems happy.
So that was the end of March. Two months of growing and mowing and rains and I was desperate for some mulch in my earliest-ever and most-promising tomato bed. My lawn is still sparse from bulldozer traffic so what the heck, it’s been months since the last illegal clover shriveled and died over there, so let me just use a mower bag full, what’s the harm…. and then the tomatoes went belly-up. It scares me to think of that whole yard as still being toxic.
Leaf miners are what started all this nervousness about chemicals settling into garden. Years back I would lose most of my daffodils, snowdrops, snowflakes, amaryllis, and lycoris to narcissus bulb flies… that is used to until I started sprinkling grub killer around the bulbs. The bulb flies disappeared and that was awesome but then one summer I realized how perfect all the leaves on my columbine (Aquilegia) were. Perfect leaves on columbine is something I’ve never seen in this garden, they always end up with a bunch of leaf miner tunnels and it’s not perfect but not that big a deal either. If I feel like it the foliage is trimmed back, and new growth returns quickly, but it was weird to not see them.
Columbine often seeds into areas where I planted daffodils and snowdrops. The columbine takes up the grub killer and becomes poisonous enough to kill the leaf miners. Whatever else sprouts there also becomes poisonous. The leaves decay and the compost becomes poisonous. Many people say the pollen and nectar of the flowers contains the poison and the bees suffer… and of course people love bees… but think of the crickets and katydids living in the shrubs which also share that soil, suddenly they’re as likely to die as the leaf miners are.
One bag of grub killer would last me for years since I used it so sparingly, but today it’s only columbine in the far reaches of the yard which ever show an occasional leaf miner. They’re basically extinct in my yard. Just imagine how a normal person would use a whole bag in a day, across their entire lawn, and from then on every grass blade, perennial plant, shrub, and tree in the yard becomes toxic to insects. Think of how many neighbors use Lawn Doctors and Tru Greens, and I don’t think they use anything less-toxic than the unlicensed, off the shelf products we gardeners use. No wonder insect populations are crashing.
I’m probably preaching to the choir here. I already have some much-smaller, far-less amazing tomato plants to plant in another unmulched bed, and so what if there aren’t any leaf miners. I just hate to think of everything else we’re losing.
Hope you’re having a great week. Happy June!
