It is the worst weed I can think of and is all the bad weeds in one - irritates the skin if handled making it very itchy, hard to kill because of deep roots and Roundup has little effect, animals won't touch it and it sicken them if they did, it spreads because of its roots and seeds. Just plain nasty.
ReplyDeleteAgree its leafy weed sticks and clings to everything especially cloths of any kind. Hoe do you get rid of it.
ReplyDeleteThe only practical way I can think of is possibly black plastic on the ground for at least several months in the summer.
