How do I get rid of Nutsedge?
Cardinal Lawn Care: Taking Care of Lawns in Arnold and Pevely, MO Since 2010
So it’s mid-summer, and your lawn has nutsedge, also known as nutgrass, threatening to take over it. You’ve tried lots of weed control products from big box stores—but nothing seems to work.
You’ve also tried pulling the weeds out, but you don’t have success because you didn’t dig out all of the tubers and rhizomes that reproduce new plants throughout your yard.
Instead, you need a professional lawn service to apply the right weed control and other lawn maintenance services to eradicate these weeds from your yard once and for all.
In this article, we’ll describe what nutsedge is, why it’s hard to get rid of, and how we at Cardinal Lawn Care eradicate nutsedge from your lawn.
Nutsedge Is Not a Regular Weed
The reason why you and other folks have a hard time clearing out nutsedge from your lawn is that you’re treating it like a regular weed such as dandelions and crabgrass.
But nutsedge isn’t a broadleaf or grassy weed. Instead, it’s a sedge, and it spreads differently than regular weeds.
Indeed, nutgrass has three different ways to spread throughout your MO lawn:
- Its tubers called nutlets
- Rhizomes that are underground stems that propagate
- Seed heads that are not as efficient in producing new plants.
Nutsedge is also an aggressive weed—it will grow and produce new plants from mid-summer to the first frost in the fall.
And the first frost will only kill aboveground sedges. The tubers and rhizomes can overwinter and start growing the following year again.
How We Get Rid of Nutgrass
Traditional weed control products don’t work on nutsedge. Instead, we use a product specifically created to get rid of it.
Also, if you have poorly draining or compacted soil, we recommend that you allow us to core aerate, fertilize and reseed that area where nutgrass is taking over.
It’s important that we apply nutsedge control on your yard in late spring or early summer before their tubers start to develop. Once we’re in mid-summer, it’s too late to apply nutsedge control because the rhizomes and tubers are busy reproducing new sedges throughout your lawn.
Lawn Maintenance Tips
If you want to continue eradicating nutsedge from your yard or you want to prevent it from growing on it, here are some maintenance tips to remember:
- Keep mowing your lawn and only take the first third off the top
- Keep fertilizing your lawn, so it grows thick to crowd out all weeds including nutgrass
- Keep irrigating your lawn with only 1” – 1 ½” of water per week
- Continue using weed control to stop broadleaf and grassy weeds from taking over your lawn.
