Roundup is darned expensive! I want to kill off a bunch of bermuda grass to make room for a garden this year, and I understand this is the only way to kill the stuff.
Is there something else that will kill the grass cheaper, but not pollute the soil so I can grow vegetables a few weeks (or months perhaps) later?
by the way, I'm planning to spray the grass to kill it...then cover it with black plastic. Wait a few weeks for it to get warm enough not to kill my tomatos then plant them (transplants from local nursery stock of 5" or so plants) by cutting X's in the plastic about 6" and planting the tomatos, then mulching right next to the plant.
Do I pose any problems to my plants by doing the above method? Does the black plastic pose any risk of getting too hot for my plants?
Thanks!
