i use a stirrup hoe in open areas or shredded leaves around plants to prevent germination. crab grass and everything else under the sun is in my garden but i keep up with the hoe and by now it is so hot and without rain weeds seldom start except pursalne aka as the weed from he11 here
. come august it cools a bit and i see weeds. you just have to keep up or give up, weeds never stop until october.
