By accident, I discovered that WVO is an excellent weed/grass killer. I had a spill on my lawn one day, and a week later I noticed a bare spot where the ever-difficult-to-kill bermuda grass had fallen dead, roots and all. So much for using this as a fertilizer, but it can be used as a non-toxic, biodegradable weed killer. Studies have shown that the chemical stuff can deform amphibians, so the replacement with WVO is exciting(especially for frogs, lizards and snakes). So I mix 50% WVO and 50% water and shake it up in a spray container, then coat some tough weeds with the watery WVO mix. It works.
