| Thanks, sparrowhawk, but I'm afraid that this would kill my roses as well as the grass that's creeping into the center of them :) I can dig out the grass around the outside but I have a hedge that is monstrous and has thorns like you would not believe! I can reach the center with the long wand on my sprayer, but digging it out is beyond me, since I don't own a suit of armor LOL! |
