Can this product be applied in fall and spring to prevent crabgrass?
Pennington Crabgrass Preventer with Barricade 5-10-25 is safe to use on various cool and warm season grasses to prevent crabgrass, as well as various other weeds. We would recommend checking out our Cool Season and Warm Season Lawn Schedules for information on when the products should be used.
