This winter, the only thing that has seemed to thrive are the weeds.The predominant types are dandelion looking plants which I have dug up by hand and a grassy type of weed that seems to grow in small clumps everywhere. The blades are thinner than johnson grass and neighbors have told me it is nutgrass. Can you provide the best method to eliminate and control.

It's really important to positively identify weeds because not all weed killers are effective against all weeds. Nutgrass is a grass-like plant pulls out easily enough, but tiny nutlets or tubers are always left behind. In a few days, a new plant emerges. If it is nutgrass, you may need to spot treat with glyphosate (Round Up). Since this is a vegetation killer, it will kill anything it touches so use it carefully. If you have St. Augustine grass (including floratam), centipede, zoysia, and carpetgrass lawns, you can use Scotts Bonus S for Southern Lawns to control most weeds. It's not safe to use on Bermuda grass, though. If you're growing bermuda, you can use Manage, Image, or Green Light Wipe Out. Be sure you read and follow label directions.
