A fast acting way to remove moss & algae in lawns, based on naturally occurring pelargonic acid. Mix 17ml with 1 litre of water & apply in a watering can direct onto the moss patches in your lawn. It is effective at low temperatures & biodegradable. Please note it is non-selective so will also kill grass & clover if it comes into contact with the leaves, so re-seeding may be necessary once the moss has been removed.
