I pinned something about a home-made weed killer solution using regular, grocery store vinegar. Then I read another post that this could not possibly work.
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.
That is freakin' great! So, then, I did this little experiment on clover to show here. This is the before pic with three little patches of clover in the brick. I sprinkled the first two with the vinegar solution.
Here they are less than 24 hours later. If you look close, you can see the shriveled up remains of the first two. Even the last one seems to have suffered from sprinkling some of the small ones that were close by. (Good reason not to get too close to the good plants.)
No before pics for the following, but they show that it worked on different weeds and grasses
Maybe the point of the naysayers is that this will not be killing the roots. Still, if I have to sprinkle this much safer, cheaper stuff a few times I'm still ahead. There may be a few hardy weeds that will keep coming back--dandelions and such, but most root systems need those leaves to stay alive in the long run.
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.
