Bermuda/Wire grass removal
How can I get rid of bermuda/wire grass in a 324 sqft area of my lawn. Digging up some of it exposes a network of roots. I was thinking about spraying roundup and then tilling the soil/roots and removing all the debris.
Bermudagrass is extremely difficult to get rid of and killing it with glyphosate, then reseeding is usually the best course of action. While there is an herbicide, fenoxaprop, which "surpresses" Bermudagrass, it requires multiple applications for years.http://extension.umd.edu/hgic/bermudagrass
If you plant to reseed, keep in mind that late summer/early fall is the best time. You probably should treat the area with glyphosate and wait a few weeks, then retreat if you see ANY green, before seeding to insure that no Bermudagrass, no matter how small, can is still alive.
