Kill Crabgrass Bermuda Lawn
Most of the time we don’t treat crabgrass in the lawn during hot temps. However, if we want to kill the crabgrass in our Bermuda lawn it should be done before the great growing conditions that come in a few weeks. In this video, Doc shows you how and when to kill crabgrass in your Bermuda lawn.

The prevalent species of Digitaria in North America are large crabgrass sometimes known as hairy crabgrass; and smooth crabgrass. These species often become problem weeds in lawns and gardens, growing especially well in thin lawns that are watered lightly, under fertilized, and poorly drained. They are annual plants, and one plant is capable of producing 150,000 seeds per season. The seeds germinate in the late spring and early summer and out compete the domesticated lawn grasses, expanding outward in a circle up to 30 cm (12 in) in diameter. In the autumn when the plants die, they leave large voids in the lawn. The voids then become prime areas for the crabgrass seeds to germinate the following season.
Biological control is preferable over herbicide use on lawns, as crabgrass emergence is not the cause of poor lawn health but a symptom, and it will return annually if the lawn is not restored with fertilization and proper watering. Crabgrass is quickly out competed by healthy lawn grass because, as an annual plant, crabgrass dies off in autumn and needs open conditions for its germination the following spring.
