Q: Every year in August and September I start to see this grass (or weed? ) infesting my bermudagrass lawn. It seems to be getting a little worse each year. What is it? How can I get rid of it?
A: The weed is green kyllinga. It’s a member of the sedge family . Like all sedges (nutsedge, etc) it is tough to control. Over-watered lawns provide ideal habitat so be sure to water only once per week, in the absence of rainfall.
Apply a pre-emergent herbicide containing benefin, bensulide, dithiopyr, pendimethalin, or prodiamine in March and repeat in early June.
