Now, I don't have a vegetable garden, but I do have three rows of raspberries. When I created that patch, first I lined the rows between with that black landscaping paper that blocks weeds. Then I topped that with a few inches of bark mulch. Within two years, I ended up stealing the bark mulch for flowerbeds (I kept expanding.
). So, the cheaper option:. Every time I mowed the lawns, I dumped the grass clippings between the raspberry cane rows. I learned that a thick layer of those grass clippings really works well to keep the weeds down. Have to keep adding more, because the grass clippings eventually break down and go into the soil, which is also a really good thing!
now I mulch my strawberry patch with grass clippings as well.
