The kind folks at Scotts just sent me this Nutsedge alert! Their products are great ... gotta stay ahead of nutsedge.
This Grassy weed Is Not Technically a Grass; It's a Sedge and Is Very Difficult to Control
Nutsedge, also known as nutgrass, seeks out the moist, poorly drained sections of your yard or garden. Its leaves are grasslike and yellow-green, while the spiky head is purple or yellow. It's a tough weed to control because it grows from tiny tubers, or nutlets, that form on roots. Pull out the roots and some tubers will stay behind to grow.

Prevention and Maintenance
Mow High to Help Control Nutsedge
Depending on your turf type and latitude, you can help control nutsedge or nutgrass by changing the way you mow. Mowing your lawn at about 3 inches lets the grass crowd out nutsedge and other weeds. Mowing short stimulates nutsedge.
Kill Nutsedge in Landscaped Areas
If you have a few plants, you may be lucky and succeed in pulling them out, especially if they're young. If not, Ortho® Nutsedge Killer For Lawns is effective in killing listed weeds in established landscape plantings. You can also control nutsedge in your mulched areas by applying Roundup® Weed & Grass Killer Ready-To-Use Plus. Make sure you don't spray the plants you like. Do NOT use this product to spot-treat in your lawn. Always read the label before you apply.
