Spruce Weed & Grass Killer is the hardworking, worry-free weed solution. Spruce is a fast-acting weed killer that works on contact, with visible results in one hour. The powerful formula works differently than most weed killers, using dehydration to kill weeds. Spruce is safe for use around people and pets when used as directed. Spruce is also backed by the Good Housekeeping seal. Spruce kills all types of weeds and grasses including dandelions, large crabgrass, white clover, dollarweed, and morning glory. The EZ-Aim applicator delivers a precise, continuous spray perfect for spot treatment of stubborn weeds in cracks and edges, as well as on-the-go maintenance of mulch beds, driveways, and paver stones; it is not designed for use on lawns. The 10-ounce bottle can treat up to 60 weeds and should be sprayed on the entire plant, not just the root.
