Crabgrass, an annual warm-season grassy weed, invades lawns kept too short or with shallow roots resulting from frequent but superficial irrigation. Its seeds sprout in spring when the soil temperature begins to hold above 55 degrees Fahrenheit. Before dying in the cold, crabgrass plants reseed to start their life cycle over again the following spring. Keeping your lawn tall and watering it deeply is one way of preventing crabgrass. Another is to use a pre-emergence herbicide, such as ScottsŪ HaltsŪ Crabgrass Preventer, which kills the seeds.
Things You'll Need
Spreader
ScottsŪ HaltsŪ Crabgrass Preventer
Gloves
Adjust your spreader according to the settings the manufacturer recommends. Set a rotary spreader to 2?, for instance. If you use a drop spreader, the ideal setting is 4?.
Place the weed killer in the spreader. Use 2 lbs. per 1,000 square feet of lawn. The bag has enough herbicide to treat 5,000 square feet. Wear gloves to protect your skin from the chemical.
Walk at a normal pace across your lawn, broadcasting the weed killer until your spreader is empty. Take this step in late winter to early spring before the crabgrass seeds germinate. ScottsŪ HaltsŪ Crabgrass Preventer isn't labeled to kill the developing weed.
Tips & Warnings
Don't apply to dichondra and bentgrass. Use it only on established lawns for a maximum of two times in one year. Don't seed the area treated for at least four months following application.
