How to apply: apply with a hydraulic sprayer or watering can, 3 days after and 4 days before mowing. The blackened moss should be ready to rake out 7-10 days after treatment. Heavy infestations may need a second treatment.
Mosses are non-vascular plants that are very well adapted to colonising areas quickly, so they can come back when conditions favour them. Where this happens, up to three applications may be made in any one year.
Half fill the applicator with clean water, add the concentrate as needed and mix well while adding the rest of the water. Apply evenly, avoiding overlaps and missed areas. If no rain falls within 2 days of application, water the treated area thoroughly. Do not apply in hot, dry or frosty weather. Keep off treated areas and keep pets away until they are dry. Do not apply the concentrate directly onto lawns.
