How does nut grass propagate?
Answers:
Scenicnursery.com says: "As the plant develops it starts sending out runners and then creates tubers or “NUTS” under ground. These nuts store nutrients and keep sprouting until they run out of food.
This last is the key to nut grass control. You have to keep them down until every nut is exhausted. At some point they get weaker and thinner and often people quit controlling them. Then they discover, in about a month, the nut grass is back as heavy as before....
An older product that works is called “ Weed Hoe”. This will kill nut grass in a lawn environment if applied correctly. Application rate is important but it can be useful in controlling nut grass in lawns."

I read about his today. Seems they grow on tubulers. If no more than 3 blades you should keep pulling. the tubulers will only reproduce so many times before it dies off. However if it's propagating in a large area you should dig at least 8" down to remove plants including tubulars and re-seed. Do a search on google. Depending on type....mine is purple nutsedge....I just keep pulling it and it eventually dies away. Also you can plant something to create shade and it will eventually die off.

Nut Grass doesn't propagate per say, the nut in the main grass nut puts out smaller nuts (seeds) next to the mother plant, you can pull the mother plant , but the younger plants will soon replace her. Nut grass is one of those pests grasses that will respond well to chemicals. There are basically 2 kinds of chemicals that kill grasses one kind Will kill any plant that is bladed, the other will kill everything that is leafed, or clover shaped. You want to get the product that kills bladed plants. Nut Grass will drive you nuts!
