Spot-Spraying Weeds in Dormant Bermuda with Glyphosate

In winter, Bermuda grass turns completely brown and dormant, while many weeds stay green. This window allows careful spot-spraying of glyphosate (Roundup) or glufosinate (Finale) on green weeds without harming the grass—because these herbicides are only absorbed by green tissue. Get on your knees and verify zero green Bermuda blades at soil level before spraying. This technique works ONLY on Bermuda; zoysia and centipede often retain green sprigs at the base and will be killed.

Read labels carefully, spray on a calm day, and target only the weeds. In a few weeks, weeds die; by spring, Bermuda fills in.
