Here is an idea to control Bermudagrass

Bermudagrass is problem for a lot of Tri-City lawns.  It is the grass with deep roots and runs it's tendrils throughout the yard spreading where ever it feels like it.   Bayer has come out with Bermudagrass Control for lawns, it is a growth regulator that supresses the growth of the Bermudagrass and lets your preferred lawn to choke it out.  Timing is critical on applying it, you want to hit the Bermudagrass when it begins to emerge in early April, then repeat applications on a monthly basis until it is no longer trying to grow.  Easy to apply with the Read to Spray Bottle (RTS), just hook to a hose and begin spraying only the affected areas of the lawn.  Be sure to let the product dry completely after application, before letting kids or pets back on the lawn.   We stock it regularly here at Job's.
