Chickweed is a low-growing annual weed that can be easily recognized by its sprouting white flower buds (similar to that of a dandelion). Chickweed grows and spreads rapidly through Bermuda grass and can overtake a lawn sodded with Bermuda grass if not controlled. Eliminating chickweed from your lawn is a time-consuming but simple process that involves a combination treatment of hand-pulling and herbicide.
Identify all of the chickweed in your lawn that you wish to eliminate. Chickweed can grow in small patches of 1 square foot or larger patches of several feet.
Begin pulling chickweed patches and disposing of them into the trash bag. When pulling, try to get as much of the root as possible to prevent any future growth of the weed in your lawn.
Fill an empty, clean spray bottle with 1 cup of herbicide and mix in 1 cup of water.
Spray onto the soil where the chickweed was pulled. Be sure to direct the spray to precisely the spot where the chickweed grew and not onto the Bermuda sod lawn. A small amount of herbicide drizzle will not harm Bermuda sod lawn, but you do not want to directly spray Bermuda sod lawn with herbicide, as it will kill desirable patches of your lawn.
Check the area once per week to determine whether new growth of chickweed is occurring. If necessary, hand-pull chickweed again and spray the affected area with herbicide. Depending on the severity of chickweed in your lawn, the process could take one to three weeks.
