re: How to make a pet friendly weed killer?

30% vinegar and dawn dish soap

There's a recent thread on this.

After using the $22-per-gallon 30% cleaning vinegar from Lowe's / Home Depot with a little dish soap I may never use Roundup again.

30% vinegar kills weeds like nutsedge that Roundup sometimes can't kill, and any overspray kills mold on your walkways.



The cheaper cleaning vinegar from Walmart doesn't list its concentration but it appears to be only 6% so it's probably useless as a weed killer.

I'm told that if you mix 1.5 Lb. of dry citric acid with water to get 1/2 gallon of solution it's about the same effect and a bit cheaper. Waiting to try that.
