Why Is My Lawn Full of Moss? Causes and Fixes

When a lawn is struggling, moss will often come to take its place. Moss is not the ‘problem’ as much as it is the symptom. The positive: grass is resilient if the factors are rearranged. For help from Landscapers Gloucester, visit https://phoenixgardenersgloucester.co.uk/services/landscaping/

Reasons behind the presence of moss in UK lawns:

Moss likes wet, shady, low-nutrient spaces. The most common places include:

Deciduous trees, fences or north-facing gardens

Compacted soil (usually a result of heavy foot traffic) that prevents adequate drainage

Rainwater logging due to poor drainage

Acidic soil (moss loves it, the grass usually hates it)

Mowing too low, which causes the grass to become thin, and moss moves in

Thin grass coverage or low nutrients.

Fixes that actually work

Start with the basics:

Mow taller and avoid scalping the lawn

Spring or late summer: scarify (rake out moss and thatch)

Use a garden fork or hollow-tine aerator to relieve compaction

Top-dress with a sandy loam; fill in low spots for better drainage.

A suitable fertiliser is best suited to thicken grass

Then overseed the bare patches so it does not get re-infested with moss.

A moss killer can be used, however, it is best as part of a plan undertaken which recognises that the moss usually returns.

When to get help

If a lawn is still spongy for days, or moss returns faster than you can trim it out, you have to either drain the area below ground. With the help of a landscaper, you can select which fix would be cost-effective for you.
