Spruce Weed & Grass Killer is the hard working, worry-free weed solution. Spruce is safe for use around people, pets & bees when used as directed. Spruce is a fast-acting weed killer that works on contact, with visible results in 1 hour, dead weeds in 1 day. The powerful formula works differently than most weed killers, using dehydration to kill weeds and should be sprayed on the entire plant, not just the root. Spruce also prevents regrowth. Spruce kills all types of weeds and grasses, including dandelions, large crabgrass, white clover, dollarweed, and morning glory. Spruce EZ-AIM is a Precision Shot Aerosol great for spot treatment of weeds in landscape areas, raised beds, cracks in pavers, walkways and driveways; it is not designed for use on lawns. Each 10oz bottle can treat up to 60 weeds. Spruce is also backed by the Good Housekeeping seal.
