During which month(s) should it be applied and how often can it be applied?
Pre-emergent applications are applied twice a year, up to 3 times a year in some regions, sometime in late fall and early spring. Please contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
