This service provides an analysis of soil texture, pH, organic matter and three major plant nutrients (potassium, phosphorus and magnesium) for gardeners. You receive a detailed interpretation of the results as well as fertiliser recommendations for either fruit, vegetables, ornamentals or lawns. A fee is charged for this service; RHS members: £25 per sample; non-members £30 per sample.
A pack containing sample bags, a pre-addressed envelope and sampling instructions for those wishing to use the service is available on request. It is important to follow the instructions carefully and send the samples and correct fee back in the envelope provided. The completed report, which is presented in a neat folder, is then usually returned within 14 days.
Please note that the service only involves analysis of nutrients in garden soils. Nutrient analyses of composts, manures or container media are not available, nor is the analysis of potential soil contamination.
