Once again, the blogosphere is full of recipes for weed killer, lawn restorer, insecticides, etc., all containing dish detergent. Most of them call specifically for Dawn, although I recently encountered someone promoting Joy instead. The most popular herbicide recipe includes vinegar and dish detergent. Some add Epsom salts. Others add plain table salt. It’s a supposedly “organic” or “natural” alternative to a purchased product.
Every so often I come across an article that explains something so much better than I ever could. This is one of those times.
Tsu Dho Nimh writes a blog called Lazy Gardening SMACKDOWN. Back in 2013, he tackled the viral advice about making your own herbicide out of vinegar, detergent, and some other ingredients. I’ve been meaning to cover this topic, because this homemade “herbicide” doesn’t work. But then I saw Nimh’s article, and realized that he did a much more thorough job of explaining it all.
