Soil Type & Structure
The top soil of your lawn is a living mantel of soil microbia that live in the organic matter, processing and transporting nutrients to the roots of the lawn grasses.
The depth and type (sand, silt, loam etc) will determine the correct management regime for your lawn.
The subsoil beneath is also important as the porosity (drainage) will have a big effect on the leaching of nutrients or water-logging in some situations.
A LawnFix appraisal will identify what your lawn soil is all about - depth, compaction, organic matter, structure, subsoil and if necessary we collect samples and send them to a laboratory for nutrient status testing.
Each lawn is unique, it is often a mistake to conclude that it is the same as your neighbours
