Clay or sandy soil can be improved by adding organic matter to improve the soil structure.
Soil Improver can be applied anytime, but if it is to be dug in, care must be taken to avoid digging/forking wet soil, as it may damage the soil structure.
Rates of application will vary, depending on the type of soil you have and the existing organic content etc. As a guide, typical application rates for digging into soils with low levels of organic matter, are as follows:
Heavy clay soil - a layer, 75mm deep, should be incorporated to a depth of 200mm
Light sandy soil - a layer, 30mm deep, should be incorporated to a depth of 200mm,
Dig over the area to be improved, taking care not to disturb existing plants or their roots. Spread the soil improver over the area to the required depth and then work in using a fork.
