Flower garden is weed free. How do I save this mode. Is nearby some chemical I can put down to stop the weed.
Answers: Mulch. It looks nice and will slow down the weeds. To hang on to it totally weed free you'll still have a few weed that will work their way through to verbs out.
There is a Weed and Feed formula available from Preen. It prevents weeds, and fertilizes at indistinguishable time. You simply sprinkle it over the garden to prevent weeds from sprouting. I've used it for several years immediately, and my garden is almost weed free.
