Now, I have to say this in the defense of all organic herbicides: they work best on young weeds that are still growing. In fact, you would ideally spray them within the first week or two of their life. These, obviously, are older, more experienced weeds, which would require multiple treatments.
But here’s the thing: you hardly need an herbicide when it comes to two week-old weeds. When a weed is only two weeks old, it takes nothing to knock it back. You could step on it, or glare at it. You can take out a row of baby weeds with a hoe in the time it would take you to walk to the counter at the garden center and swipe your credit card.
But I digress. Here, to the right, is the same patch of weeds after a vigorous and enthusiastic application of Nature’s Avenger.
If you look closely, you’ll see that it’s a little browner, but not much.
And what about the vinegar? It did no better. In this image to the left, you’ll see the entire sidewalk. The foreground was sprayed with Nature’s
Avenger, and the second half, off in the distance, was sprayed with vinegar. Some of it looks brown, but some of it was brown already.
And here’s what occurs to me. I’ve got to dig the damn things out anyway, whether they’re dead or alive. I don’t see how this saves me any work.
So: Vinegar, for about two cents an ounce, or the good stuff for about 37 cents an ounce? You decide.
Meanwhile, I still have a sidewalk full of weeds to deal with. Once I’ve yanked the weeds out, I’ll use my even cheaper herbicide treatment to keep them from re-sprouting: I’ll pour leftover boiling water from the kitchen into the cracks to try to kill the roots and the seeds.
Then I’ll forget about it for another year or two. Until the neighbors really start to make me look bad.
Anybody else have an herbicide success story? Blow torches, perhaps?Posted by Amy Stewart on July 7, 2008 at 5:35 am, in the category Taking Your Gardening Dollar.
