What is Crabgrass Preventer?

how long after crabgrass preventer can i seedCrabgrass preventer is a herbicide that prevents crabgrass from germinating. It works by creating a barrier on the soil surface, preventing the crabgrass seeds from developing roots and sprouting. Crabgrass preventer is typically applied in the spring before the soil temperature reaches 55 degrees Fahrenheit.

How Long After Crabgrass Preventer Can I Seed?

The answer to this question depends on the type of crabgrass preventer you use. There are two types of crabgrass preventer: those that contain a pre-emergent herbicide and those that do not.

Pre-emergent crabgrass preventer is the most common type of crabgrass preventer. It contains a herbicide that prevents crabgrass from germinating. If you apply pre-emergent crabgrass preventer, you should wait at least six weeks before seeding your lawn.

This is because the herbicide can also prevent grass seeds from germinating. If you seed your lawn too soon after applying pre-emergent crabgrass preventer, your grass seeds may not sprout.

However, keep in mind that post-emergent crabgrass preventer is not as effective as pre-emergent crabgrass preventer.

It can only kill crabgrass that has already sprouted, and it may not prevent new crabgrass from germinating.
