HELP!! I have nut grass growing in my yard that I cannot get rid of. It is NOT in my lawn area, but in the crushed granite. I've tried using weed killer, tried digging it up, putting down weed screen, but it still pops up. I've been digging up these little buggers for years and I'm getting frustrated. Any help you can offer to get rid of it once and for all would be appreciative!

Nutgrass (nutsedge is its proper name) is indeed a pesky foe! You have several options for controlling it. Although none of them are quick and easy, they will work if you are diligent. Assuming it is in the lawn, you can hand dig the nutlets. Then wait a few days for more to sprout and remove them immediately. A second option is to spray the nutsedge with a herbicide containing glyphosate (such as Roundup). However, if the nutsedge is in your lawn, glyphosate will kill the grass as well. You can paint the herbicide on the individual nutsedge blades. Each time it returns, you have to reapply. Nutsedge is tenacious, and whatever method you choose, keep after it regularly. If you let it get a hold again, you've lost ground! The key to any approach is to never allow it to reestablish and regain its stored reserves, which are in small nutlike tubers below ground. Keep forcing it to use stored reserves to send up more growth and then quickly dig or spray it again. If you don't quit you will win the battle.
