As stated on the product label, "The efficacy of Ike's Sandbur & Crabgrass Preventer will be best if the application is followed by one-half inch of rainfall or its equivalent in sprinkler irrigation. If Sandbur & Crabgrass Preventer is not activated by rainfall or irrigation within 30 days, weed control may be erratic." After this, the area will need time to completely dry. Once dry, there is no specific time needed before another rainfall. Please be sure to review the product label for more information and complete application instructions.
