Conditions for the application of Crabgrass Control, must be cool and moist. In Iowa, there is a very tight window of opportunity. To be most effective, the Spring Crabgrass Control treatment, should be applied between March 15 and April 15. Crabgrass Control can also be applied in the Fall. This application will provide a stronger barrier against new Crabgrass seedlings in the Spring.
