Ive planted my first vegetable garden and Im wondering what I can do to help prevent weeds in the garden. I know I wont be able to keep all of them out but can I put tree bark mulch down or should I use some other type of barrier? Just wondering what everybody else does out there. When I was a kid my dad always grew peppers and just threw grass clippings in the garden but I cant do that cause I don't have a bagger for my mower.
