When should I put crabgrass control down?

Pre-emergent crabgrass control means just that...BEFORE crabgrass germinates! This product, just as other similar crabgrass controls on the market, needs to be applied before the active growth of the crabgrass plant begins. In the Northern regions of the country, a pre-emergent to control crabgrass should be applied the end of March through the end of April. In the Southern regions of the country, a pre-emergent to control crabgrass should be applied the beginning of February through the end of March.

The chemical forms a barrier on the soil surface, preventing the crabgrass seedlings from germinating. If the soil surface is disturbed, the crabgrass from untreated areas will be able to grow. A second application later in the season is recommended for longer control of crabgrass. Pre-emergent control of crabgrass is the most desirable and safest method for crabgrass eradication. Although there are post-emergent control products on the market, desirable lawn areas can be easily damaged if label instructions are not exactly followed.
