Can You Spray Weed Killer on a Newly Seeded Lawn? Timing Matters

Spring-seeded lawns often get weedy, which is why autumn is the recommended time for planting cool-season grasses like Kentucky bluegrass and tall fescue. Before applying any herbicide, wait until the new turf has grown enough to require mowing three times. Young grass plants are highly sensitive to weed killers and can be damaged if sprayed too early.
