How long is the product, following application, active before a rain and is there an expiration date on the bag if not how long can it be stored?
It is best to apply Hi-Yield Crabgrass Weed Control in Illinois the beginning of May or at least 2-4 weeks before crabgrass germination. We recommend that the product is watered in after application with at least 1/2in water or before a rain. The shlef life if stored in a cool dry area is up to 3 years.
