How to Improve Clay Soil for a Lawn

Hollow-tine aeration to relieve compaction, followed by topdressing with a sandy loam mix worked into the aeration holes, and overseeding to thicken thin areas. Repeated annually, this gradually opens up the soil structure without needing to dig the lawn up.

Much of Cambridgeshire sits on clay-rich geology, which holds nutrients well but drains poorly compared with sandier soils found elsewhere in the country. This makes aeration and drainage-focused lawn care more important here than in areas with naturally free-draining ground.

Once a year, ideally in spring or autumn, is enough for most clay lawns. Heavily used areas or lawns that regularly puddle after rain may benefit from aeration twice a year until the drainage visibly improves.
