Product Overview

Green Light Amaze Grass and Weed Preventer is an herbicide formulated to control certain types of broadleaf weeds and annual grasses prior to emergence. This formula creates a protective barrier on the soil's surface which prevents unwanted weeds and grasses from emerging. It can treat up to 4,000 square feet and can last the whole season making it an affordable choice. This product is in granules making it easy to apply, just sprinkler it over the top of foliage.

Green Light Amaze stops weeds during germination. IT WILL NOT KILL ESTABLISHED WEEDS. Proper timing of application is important for best results. To be effective, this must be applied before the weeds emerge.

Will Green Light Preventer kill bamboo ?

Green Light Amaze Grass and Weed Preventer is not labeled for bamboo. Since bamboo roots go so deep, you would need to apply either a product like Rodeo/Roundup QuikPro at the highest rates directly to the fresh cut stump of the bamboo after you cut it down level to the ground, or use a brush and stump killer undiluted directly on the fresh stump.
