Nothing seems to faze sedge, and it grow seemingly without hindrance in both vegetable garden and lawn. How can it be not only suppressed but eliminated?

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. 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.
