Hairy Crabgrass is a summer annual grassy weed that is also known as Large Crabgrass or by its scientific name, Digitaria sanguinalis. These types of lawn weeds often require a professional application of a select crabgrass killer.
Water less frequently but more deeply: One common mistake homeowners make is to water their lawns lightly and frequently. A deep watering every few days is actually better for your grass and discourages crabgrass. Allowing your lawn to dry out between watering actually encourages grass to put down deeper roots. Light watering encourages shallow surface roots that can dry out easily.
Full sun (6 or more hours of direct sunlight a day)Partial Shade (Direct sunlight only part of the day, 2-6 hours)
Fertilize regularly for your grass types: Fertilizer encourages growth, and a flush of new lawn growth will crowd out crabgrass seedlings.
