An effective ready to use weed control which uses acetic acid and natural ingredients to control annual and perennial weeds on hard surfaces like paths, patios and gravel with visible results after 24 hours. The formula dries quickly, leaving the treated area safe to be seeded or planted 24 hours after application – as well as being harmless to children, pets and wildlife once dried. Can be used year round when no frost is present. 60g/1 acetic acid. Glyphosate Free. 1 litre treats up to 35 square metres.
