and weed is in my flower beds where bulbs & perennials are planted. Also in my lawn. What do I do & how do I do it?
Charlene W on Jul 29, 2018
BEST ANSWER: I was trying to get rid of chamberweed. It stopped it from coming up but I should have waiting until later in the spring to put it down. It needs to be applied every few months or the weeds will still come up. Since it likes hot weather, applying later would mean only 2 applications instead of three (I think.)
