A well-trodden lawn, or grass on heavy clay soil can quickly become compacted.
In hot weather the surface bakes hard and can crack. Water does not drain freely and puddles form on the surface.
This is called compaction and leads to water logging which is bad news for the health of the lawn.
In most circumstances, it is easy to rectify, but it does require some effect. The best time to do this is when the soil is moist in early summer or autumn.
Read our step-by-step guide below on how to deal with poor drainage:
Use a hollow tined aerator to remove soil cores from your lawn, or use a garden fork.
Brush Westland Lawn & Turf Dressing into the resulting holes and repeat annually until the problem improves.
