It was overwhelming, that trip I took to the big-box store.
Upon entry, I was smacked with towering shelves of toxic weed killer.
Here is my recipe for non-toxic weed killer. I have used it for several years here in the Midwest with good results.
I mix everything together and store it in the white vinegar gallon container. I use a smaller spray bottle to apply to weeds.
I apply the weed killer on a dry day and let the sun help do the work.
