Weed Killers without Poison
Sigh. As you know, I'm no big fan of herbicides. And it's none of my business what the neighbors do on their own properties, as they march up and down their driveways and side flower beds with the big spray dispenser of Roundup, gleefully dumping five gallons of glyphosate preparation on perfectly innocent plants that happened to grow in the wrong place. (And spraying their own feet and legs in the process, so good luck with that, guys.)
It's none of my business, but I get cranky when I think of herbicides in the water table, to say nothing of potential impact on my garden. But all I can do is treat my property without the herbicides that make me uncomfortable. So, here's my top five ideas for controlling weeds without any chemical nasties:
Reframe your perspective: Those dandelions and purple deadnettles? The bees love them, and they are the first food for our pollinators in the spring. Give the bees a break and let your weeds grow a bit. We have some of the friendliest bees in our garden every year, and I think it's because they know they can always come eat at our house.
Mow: I know the good people who sell chemical lawn products don't want you to know this, but there's very little visual difference between a yard full of grass and one that has clover and other "weeds," especially if you mow it short. Once you think you've attracted the bees and are ready to get rid of some lawn weeds, just lower the blades on your mower. We have whole patches of our yard that basically never need mowed any more, because the low-slung clover has taken over the grass.
Boiling Water: So, having weeds in the yard is one thing, but having them in the cracks of your sidewalk or driveway is another. I get it. Every year, I take the boiling water from the canner outside and dump it on patches of offending weeds as my last step in putting up my produce. The weeds stay gone for a long time, and there is no worry about runoff. Just don't accidentally dump on your toes!
Salt Water: Ever heard of a "salted earth" strategy? That refers to the fact that salt will keep your land from growing anything. I occasionally take the leftover brine from making pickles out to places with really stubborn weed growth. The hot vinegar and salt will pretty much kill anything; just make sure it doesn't run off into your garden!
Vinegar and Dawn: Thank you to my loyal reader L. (I wasn't sure if she wanted her name used) who experimented with a gallon of vinegar mixed with a tablespoon of Dawn dishwashing liquid. According to her report and the pictures she sent, it does a bang-up job on the weeds, which are dead in a couple of days. She also shared how it will kill grass, so exercise caution. But the best news is that this solution costs about $3, compared to ten times that amount for Roundup! That's a FC&G win!
