Winter Feed & Moss Control


Moss is a common problem in lawns especially following a dark and wet winter, particularly when little maintenance has been undertaken. As part of our treatment plans we include a moss removal treatment, where we spray the lawn with liquid iron which turns the moss black almost instantly and gradually works its way down into the roots.

What is moss?

Mosses are primitive non-flowering plants that have no root structure and rely on a sufficient moisture environment being present in order for them to survive. Mosses grow slowly and are tolerant of shade and close mowing. Moss will attack your grass when it is under stress – such as sitting under water, or when there are bare soil patches in the lawn.

What causes moss?

Moss growth in lawns is caused by environmental conditions, rather than due to poor turf. The main causes of moss include:

  • Long periods of wet weather
  • Long periods of dry weather
  • Low soil fertility
  • Compacted soils
  • Low or high soil pH
  • Excessive shade
  • Poorly drained soils
  • High thatch contents
  • Poor air circulation
  • Closely mown / weak grass growth
  • Ineffective maintenance regimes

Why you need a treatment for moss

Regular moss treatment to remove moss from lawns is vital, if moss is left, it can push out the grass and starve the grass of its nutrients, not only that – it looks rather unpleasant in the summer months! A treatment plan consisting of applying chemicals, scarification and aeration will keep the moss to a minimum and most importantly it will allow the grass to come back thicker and stronger.

Regular scarification removes moss from your lawn, which in turn will help reduce the thatch layer that moss creates. The thatched layer stops the important air circulation and drainage through the soil.

Ways of treating moss

The main ways of treating moss include the use of chemicals and scarification. However, there are activities that you can do in the garden to reduce and remove the moss in your lawn; this includes:

  • Not mowing your lawn too short – Do not mow your lawn so the grass is shorter than 1 inch
  • Aerate lawns to allow water to move away from the surface
  • Prune low trees or bushes to increase air and light to the lawn
  • Feed your lawn regularly
  • Control weeds within your lawn – for the best lawn weed killers visit the RHS website
  • Scarify your lawn to remove the thatch
  • Treat moss with liquid iron or with fertilisers with high iron content

When to treat moss in lawns
