Approximately 6-8 weeks later a second feed should be applied to maintain the vigour of the grass. Subsequent fertilisation will depend on your soil type and the seasonal conditions. The final fertilisation will be required during autumn, this is an important fertilisation as it strengthens and prepares the lawn for the rigours of winter.
The main elements of Lawn fertilisers are nitrogen (N), phosphorus (P) and potassium (K).
Nitrogen is required in larger quantities than phosphorus and potassium as it is an essential component of chlorophyll, amino acids, proteins, nucleic acids, enzymes and other plant substances. Grass normally consists of 3% to 5% nitrogen this being required to ensure healthy plant growth.
Phosphorous is use to hold and transfer energy within the plant for metabolic processes. Highly mobile within the plant phosphorous is conserved and used repeatedly to assist cell production.
Potassium is second only to nitrogen in the amount required to sustain grass growth, it plays an important part in the synthesis of numerous plant compounds and in the regulation of many physiological processes.
Secondary elements such as sulphur, calcium and magnesium are also present in some fertilisers.
Ensuring the correct balance of annual fertilisation program is a skilled job we would be happy to recommend an annual program for your lawn if you require.
