Removing Bermudagrass from a Zoysiagrass Lawn: Strategies and Timing

Eliminating bermudagrass patches within a 'Zenith' zoysiagrass lawn requires patience. UGA weed specialist Tim Murphy recommends spraying the bermudagrass with glyphosate three times at four-week intervals. Starting now won't leave enough time to reseed before winter; begin the sequence next spring when bermudagrass first appears, then plant 'Zenith' in mid-summer.

Suppression Alternative

If eradication seems daunting, suppression is an option. The herbicide Weed B Gon Chickweed, Clover and Oxalis Killer damages bermudagrass but is tolerated by zoysiagrass. Spray at four-week intervals, targeting a clover plant within the bermudagrass patch to justify application.
