How to Kill Nutsedge (Nutgrass) and Other Tough Lawn Weeds

June 26, 2015

Ortho has a spray to kill tough lawn weeds like Nutsedge, Wild Onion, Wild Violet, Ground Ivy, and about 50 others including Dandelion and Clover without harming your good grass.  Ortho Nutsedge Killer for Lawns can be used on most any kind of lawn.

Ortho Nutsedge Killer for Lawns comes in two kinds of sprays.   If you only have a small patch of weeds you are trying to kill, there is a ready to spray squeeze trigger bottle (click here to check it out).  If you have a big area with lots of lawn weeds it comes in a spray bottle that attaches to the end of your hose (click here to check it out).

It is best to spray weeds when they are actively growing.  If your lawn is stressed from drought and weeds are not growing very much, wait to spray when your lawn is getting regular rain or irrigation.  Also, you do not need to drown your weeds with spray to kill them.  Just wet the leaves and they will eventually die.

You think you are getting rid of Nutsedge (also called Nutgrass) because it is easy to pull. However, it quickly grows back from the bulb-like roots that are left behind in your soil.

    Hi Aston, If I spray my lawn to get rid of the nutsedge can I still do my normal aerating and overseeding in September?

    You will need to wait 4 weeks to seed after spraying Ortho Nutsedge Killer, so sounds like your timing is perfect.

    Thank you sir. I was having a hard time finding that info on the Scotts website.
