Veronica--For weeds. It supposedly stops seeds from sprouting. Which would be weed control. Unfortunately it also stops flower seeds from sprouting. It's other up side is it acts like fertilizer. I just thought I would ask. I am originally from the Midwest, and did not know if was prevalent there. I figured if it was as good as they say Midwesterners would know corn products for gardens. Weeds grow here year round and I would like if I could find a natural way to stop them. Did not know if it sounds too good to be true? Thank you! May God bless you and your family!
