Magic Weed Killer contains 60g/l acetic acid in a ready-to-use formulation for controlling unwanted weeds and moss on hard surfaces such as patios, paths, and driveways. Not suitable for lawns or edible plants. This non-selective spray works by covering the foliage of weeds and moss, with visible effects within 4 hours and full control after 24 hours. Best used on small, tender weeds or moss under 10cm tall. May require repeat applications during the growing season. Ideally, spray in spring and repeat as necessary over the growing season, up to a maximum of 6 applications per year with an interval of 7 days between applications. One 5L bottle covers up to 50 square metres. Safe to replant once weeds and moss have died. For amateur use only.
