Preen Weed Preventer with Brilliant Blooms Fertilizer has an indefinite shelf life as long as the product is kept in a cool, dry area. Keep the container closed and away from food and domestic water supplies.

Preen Weed Preventer with Brilliant Blooms Fertilizer can stain porous surfaces such as concrete, stone, vinyl, flooring, clothing and shoes if it is not swept immediately off these surfaces or if it becomes wet on these surfaces. If you are storing the bottle, drum or bag in a potentially damp or humid location, place cardboard under the container to prevent yellow stain seepage. In an attempt to lessen or remove a stain, try a citrus-based cleaner such as Goo Gone® (a registered trademark of Magic American Products, Inc.) or Orange Hantex (manufactured by Precision™ Laboratories, Inc.).
