Off I went to remove the pin. Yet, I seemed to have a memory of accidentally killing off some grass with vinegar. Instead of deleting the pin, I went to the pinned post. There were before and after photos of a brick patio much like mine--lots of green weeds, then, lots of yellow ones. Gotta try it, right?
First time I didn't take pics of the before. I just tried it on the worst section of my patio. (Yes, the patio is a mess. We are just barely hitting "use the patio weather" here!). Here is a shot of the after.
No before pics for the following, but they show that it worked on different weeds and grasses
I used a solution of one gallon of vinegar, one cup of salt, and 3 tablespoons of dish detergent. The pinned post called for less detergent, but I decided to go for more. I think I've mentioned my inability to follow directions before. I'd like to say I'm working on that, but I'm not.
My experiments continue, however. Once a home schooler, always a home schooler--even when the kids are gone. I'm trying straight vinegar on a few of the really large weeds in another section of the garden beds (or I probably should say weed beds to be perfectly honest) and some of the mixed solution on others. I shall let you know how it goes in the long run.
Update: The straight vinegar worked just as well on the weeds in the garden as the mix. Large weeds including a very large dandelion were completely shriveled and brown. I'll see if they come back and let you know.
