Lawn Fertiliser

Lawn Fertiliser

Lawn fertiliser is a key part of the services that lawn care companies provide. Grass plants draw upon different nutrients and other elements from the environment around them in order to thrive and ultimately survive. In lawn fertiliser, the three most important ones are Nitrogen (N), Phosphorous (P) and Potassium (K). In different ways these help the plant.

Nitrogen creates good growth and helps to give the plant stronger shoots and leaves. Often the strength of the nitrogen will impact the depth of green colour of the lawn due to increased growth. The higher the amount of nitrogen the greener the blade will become. It can also soften the blade and create more thatch if the growth is too strong. Conversely, too weak and the grass will either not green up sufficiently and will need more regular feeds.

Phosphorous is essential to help the grass establish a strong root system. Roots, of course, are so important to any plant, grass included. Helping these to strengthen via the phosphorous element of the fertiliser helps the grass to stay healthy.

Potassium helps with the general wear an tear of the lawn aiding it with disease resistance, drought and cold weather. Diseases like Fusarium can be particularly nasty around the autumn time.

The fertilisers will therefore have a mix of NPK usually specific to the season and with specific usage instructions. Some fertilisers add in Magnesium (Mg) or Iron (Fe) to boost the colour and growth.

Can I just buy my own lawn fertilsers?

Yes you can. However, many lawn fertilisers that you buy off the shelf are fast release products which release the NPK in a rapid manner giving results in a few days on some products. Whilst these are good they will need reapplying almost every 4 weeks which will dramatically increase your outlay. Our products customarily last 3 times as long, slowly releasing the nutrients over 10-12 weeks, keeping the grass well fed and nourished.

It’s a well used Lawn Care company selling point that using a professional service will be cheaper than doing it yourself.
