Moss Control in Lawns

• If you have the conditions for moss; shade, damp, poor drainage, etc – expect regular maintenance to keep it in check.
• Moss treatments need to be accompanied by scarification or raking – no easy choices!

There are a number of products to treat moss in lawns – most will be based upon iron sulphate – this turns moss black.

• Sul-Fe containing 19% sulphate of iron - is a great product for controlling moss in lawns. It blackens moss and greens grass without lush growth
• Iron sulphate mixed with sand is called Lawn Sand and is applied using a granular spreader. Liquid moss treatment are also available - including a combined moss/ weed treatment
• Do not apply too much iron sulphate as it may affect othersoil nutrients and how the grass absorbs it. Spring & Autumn are the best times.
• Make sure moss is damp when applying a treatment but not ringing wet – moss can be very absorbent.
• Scarification or raking should follow treatment after approx.4-7 days. A machine can be hired or spring tine rake used. (Compost moss separately from normal garden waste.)
• If you have bare patches on lawns it is advisable to re-seed quickly, if left alone they will be prone to invading weeds and moss. Apply a fertilizer such as a pre-seeder at the same time
