re: Dollarweed

I have a pretty large vegetable garden in my back yard and I'm constantly fighting various invasive weeds over the years I've been growing vegetables.

First it was the local nut grass and bush killer vine, then dollar weed, now it's oxalis, purslane and a tree-like weed that looks a bit like a mini mimosa tree.

The oxalis is particularly vile with the way it grows and spreads underground and no amount of spraying between plantings, tilling, hoeing, hand weeding, etc. has any impact on it.
