Why do I Keep Getting Moss in my Lawn

Moss will always come back if you don't control it. Our annual moss removal plan will keep your grass healthy and your moss out of sight.

Moss will always come back if you don't keep on top of it and implement ways to prevent moss from coming back, mainly if the conditions are right for moss in your lawn. It is a continuous battle, but the correct procedure can result in an 80 to 90% reduction in moss, making life in the following years much more manageable. The secrets to achieving this are:

• Follow the procedure at the correct time of year
• Do not be tempted to start too early in Spring
• Be thorough, and don't cut corners

Following the plan will keep your grass healthy and prevent moss from taking hold.

Our Suggested 12-Month Moss Eradication Plan

This is by no means a fixed rule, so be prepared to adjust your approach depending on your preferences and the severity of the moss. The plan can be started at any point and requires an entire 12-month cycle to maximise effectiveness in removing moss from your lawn.

Year 1

Winter

• Use Winter Green once to feed, control moss and maintain grass health
• Any moss recurrence should be controlled with either MossOff or Green-up Ferrous Sulphate

Spring

• Apply your preferred moss killer from our range two weeks before raking moss. This typically occurs from late March onwards in southern England and from April onwards elsewhere.
• Applying a moss killer at this stage does help reduce the bulk of the moss and makes it easier to rake out. Although it kills the moss, you won't remove it all with one treatment before raking. If you have a lot of moss, it does give a better result.
• Rake the moss out, then apply a second MossOff or Green-up Ferrous Sulphate treatment only. A 4-week gap is required if using ferrous sulphate twice or a ferrous sulphate and Winter Green combination.
• After 2-3 days if using ferrous sulphate or 7-10 days if using MossOff, you may need to rake lightly again before overseeding.
• Overseed - Overseeding your lawn prevents gaps from filling with dandelions and introduces new grass varieties.
• Apply Spring Fertiliser over the whole lawn when the new seed germinates. Use either Spring & Summer for Sandy Soil or Natur

Autumn

• Moss may re-occur during cooler, wetter weather, so use either MossOff or Green-up Ferrous Sulphate to suppress
• If you need to scarify and moss is present, follow the plan for Spring but start late August or early September, depending on the weather. The objective is to have all procedures completed, and the seed planted well before it gets too cold to germinate.
• Always apply an Autumn fertiliser afterwards.

Following years - maintenance programme

The Year 1 programme should return you to a healthy, grassy lawn rather than a mossy one. If your lawn starts reverting rapidly back to moss, something is causing this. Either the conditions surrounding your lawn need adjusting, or your mowing needs adjusting.

Winter

• Use Winter Green once to feed, control moss and maintain grass health
• Any further moss recurrence should be controlled with either MossOff or Green-up Ferrous Sulphate

Spring

• 2 weeks before feeding, apply MossOff or Green-up Ferrous Sulphate
• Apply Spring Fertiliser

Autumn

• To suppress moss, if present during cooler, wetter weather, use either MossOff or Green-up Ferrous Sulphate.
• If you need to scarify and moss is present, follow the plan for Spring in Year 1
• Always apply an Autumn fertiliser.
