Nutsedge in your lawn
Nutsedge, also known as nutgrass, can be difficult to control.
This perennial, grass-like weed tends to grow in moist, poorly-drained areas.
It tends to grow faster in hot weather than your actual lawn.
The leaves of this weed are yellow-green, while the spiky head is purple or yellow.
It grows from nutlets that form on the roots, which are very difficult to remove.
Even after pulling out the roots (roots can be 8-14” deep into the soil), nutlets tend to stay behind and continue the growth process of this pesky weed.
How to get rid of nutsedge!
To slow the growth process of the nutsedge, you should mow your grass at its recommended setting, which is usually a higher setting; nutsedge gets stimulated when mowing at a lower setting.
Keeping your lawn healthy, such as mowing at the right height and fertilizing, will allow your grass to have a better chance to choke out the nutsedge.
Because the nutlets are difficult to remove, you may also use a nutsedge killer to help eliminate this weed.
An established Zoysia lawn, when thick and hearty, will actually crowd out the nutsedge and help prevent spreading.
Because Zoysia is so slow-growing, you may want to help by using our nutsedge killer while the plugs are trying to fill in.
Overall, do not fret about this pesky weed, as there are solutions.
