I like the idea of using grass clippings as mulch around my tomatoes,
black
berries, grapes, and fruit trees. I am just not sure if that is
recommended or a good idea? I want to find a cheap way to prevent weeds
from growing and keep the ground moist.
I heard that the grass clippings can spread disease to the vegetables.
My dad found the clipping breeding some kind long centipede insect in the
grass.
