Kills crabgrass and other weeds in your lawn.
Ortho's most powerful lawn weed killer!
Crabgrass is an annual, grassy weed that germinates in late winter (south) through early spring (north) and dies with the first hard frost in the fall.
If a crabgrass preventer is not applied in the spring, it will become noticeable in the lawn in mid- to late-summer and grows vigorously in hot, dry weather
Crabgrass has grass blades that are wider than the rest of the lawn, low growing stems that sprawl along the ground and radiate out from the center of the plant in a star-shape
Plants form seed heads that resemble a crow’s foot, and each plant can produce over 100,000 seeds that remain viable in the soil for several years
Crabgrass lookalikes include: Coarse Fescue, Foxtail, Quackgrass, Nutsedge, Poa Annua, Goosegrass, and Nimblewell.
- Mowing at a height best for your lawn allows the grass to grow thick to help prevent crabgrass seeds from germinating by blocking sunlight’s access to the soil.
