Planted new lawn using Miracle Gro Soil as a cover for new seed approx 3 weeks ago. Lawn is coming up with patches of crabgrass in several areas. Average temp is 89-101
Hi-Yield 2, 4-D Selective Weed Killer is not labeled for crabgrass and states on the product label do not use on freshly seeded turf until grass is well established. This is typically after 2 mowings. Reseeding of lawns should be delayed following treatment. With Spring application, reseed in the Fall. With Fall application, reseed in Spring.
