when to use fertilizer?
What is the proper use of fertilizer?
Apply only when the soil is sufficiently wet to immobilize the fertilizer and prevent runoff; Do not apply on hard surfaces, such as sidewalks, patios, and driveways. If fertilizer spills or lands on hard surfaces, promptly sweep it back onto turf or return it to a proper storage container; and
Store in a closed, waterproof container that is placed indoors or raised above the ground.
