During cool, humid winter weather, moss can establish itself in shaded areas around the garden; especially in lawns.

Moss growing in lawns competes with the grass and has a detrimental effect on lawn health. Because mosses and liverworts are completely different to other plant species, you’ll need to take special steps to control them.

Systemic lawn weedkillers kill by being absorbed into the target plant, then circulated around the plant tissue in sap, through the plant’s vascular system. Moss doesn’t have a vascular system, so systemic weedkillers are prevented from doing their job.

Technically, moss doesn’t even have roots or leaves! Moss also reproduces with spores rather than seeds – it’s a very different beast to broadleaf lawn weeds.

If you need to control moss, lichen or algae, reach for Yates Surrender Moss Killer.  It's safe to use on your lawn grass and most hard surfaces, so it's very versatile.

To reduce the chances of moss returning, aerate the lawn area with a garden fork. Simply push the fork in to at least 10cm and wriggle it back and forth to create larger holes. Do this every 10-15cm, working your way around the whole lawn. It's quite hard work, but it really pays off. Immediately after aerating you can apply gypsum to the lawn, which will help to improve the soil porosity in heavily compacted soils (moss loves compacted soil).

It also helps to reduce shading over the lawn, by trimming overhanging trees and shrubs.
