The results from regular fertilizer applications are magical! We are replacing the nutrients taken out by frequent mowing. A lawn with adequate nutrients will be greener, better able to resist disease, and drought tolerant.

The type of fertilizer you need depends on your individual lawn. Jim’s Mowing Franchisees can provide our clients with a soil test, which should ensure proper frequency of application and the right products to apply. Generally, it is recommended you apply fertilizer to turf four to five times a year, roughly every six weeks.

With established turf, we are typically interested in green leaf color. The element responsible for this green color in turf, is primarily nitrogen (N). Therefore, we need a fertilizer high in nitrogen with a balance of potassium (K) and phosphorous (P). A typical N:P:K ratio for a turf fertilizer would be 22:10:8, certainly dependant on the time of year. Application is at the rate recommended on the package. Make sure the soil is damp before application and then water in thoroughly to ensure that the fertilizer is absorbed entirely, which can prevent any possible burning.

As well as the typical fertilizers, there are a whole range of organic fertilizers available. Consult your local Jim’s Mowing Franchisee for information on related programs.


1. Nitrogen (N), in most fertilizers, is derived from sulphate of ammonia, ammonium nitrate or “agran”, as well as urea and calcium nitrate.
2. Phosphorus (P), is commonly derived from superphosphate, blood and bone.
3. Potassium (K) is derived from muriate of potassium, sulphate of potassium, and potassium nitrate.

These three elements are known as the macro elements and, by law, the levels in every fertilizer are stated on the bag.

There are thirteen other essential elements for optimum plant growth; these are commonly called the micro elements and they include iron, copper, zinc, sulphur etc.

Plants also require a complex balance of other chemical elements – but in much lower quantities. Most often, individual ‘trace elements’ are not applied but, instead, a fertilizer containing the major three elements plus the trace elements is used. If you are purchasing a fertilizer without trace elements added, you can add trace or micro-elements to the fertilizers by buying a separate trace element mix. Use trace elements at the recommended label rate only.
