Use ferrous sulphate to control moss and to provide your lawn with the nutrients required to promote healthy green colour and growth. The quick-releasing nitrogen gives your lawn immediate food for early spring green-up. Use in early spring when moss is actively growing.

To ensure efficacy, make sure that the area is wet before application, and kept dry for 24 hours after. This allows time for the moss control to absorb. After the moss has tuned black, simply rake out and reseed in the bare patches.
