PROLAWN Green Demon Organic Weedkiller

Green Demon is a fast acting organic weedkiller - weeds begin to shrivel and die within a few hours of application. Green Demon has direct contact action on exposed foliage, and works best on seedling and actively growing annual weeds such as chickweed, fumitory, speedwell, nightshade, fathen, nettles, etc. Perennial and other well established weeds with extensive roots may grow back, and repeat applications may be needed to control tougher weeds. Green Demon is completely biodegradable, and leaves no residue in the soil.
