Moss thrives in Cambridge gardens because the local clay soil compacts easily and drains slowly, creating the damp conditions moss prefers. Killing moss with ferrous sulphate is only the first step. Without fixing the underlying cause, whether compaction, shade, poor drainage, or close mowing, it returns within a season.
ELawnCare treats moss as part of lawn renewal at £200 per 100m², which includes scarification, overseeding, and top dressing. The owner identifies why the moss is growing and addresses the root cause. Coverage spans CB1 to CB25 with no callout within 8 miles.

Cambridge sits on clay and clay-loam soil that compacts under foot traffic and holds water. Compacted, damp soil is perfect for moss. Shade from trees and buildings further weakens the grass, giving moss an advantage. Low mowing height stresses grass and opens space for moss to colonise.
Properties on the west side of Cambridge and along the river tend to have heavier clay, making them more moss-prone. Annual aeration in autumn is the single best prevention.
Apply ferrous sulphate to blacken and kill the moss. Wait two to three weeks. Scarify to remove the dead material. Aerate to relieve compaction. Overseed bare patches. Top dress with fine soil. Water if rain does not arrive. Raise the mowing height to 30mm to 40mm going forward.
Apply a moss killer like ferrous sulphate, wait two to three weeks, then scarify to remove dead moss. Aerate to fix compaction. Overseed bare patches and top dress. Then address the cause: raise mowing height, improve drainage, or overseed with shade-tolerant grass.
ELawnCare's lawn renewal including moss treatment, scarification, overseeding, and top dressing is £200 per 100m². This addresses both the moss and its cause. The service covers CB1 to CB25 with no callout within 8 miles.
It will if the cause is not fixed. Compaction, shade, poor drainage, and close mowing all encourage moss return. ELawnCare identifies the underlying issue and treats it alongside the visible moss, which is what separates effective treatment from a temporary fix.
