The what, why and when of fertiliser
Why we use fertiliser:

Like us, plants need food to survive and fertiliser is food for your lawn.Without fertilising your lawn very little new nutrients are readily available and so it will survive but only justThis is especially important after regular maintenance like mowing which is good for the lawn but also causes some stress to the grass plant. With the use of the correct fertiliser at the right time of the year lawns will thrive, thicken up by sending out new shoots and become lush and green, rather than just survive.

What is fertiliser?

Fertiliser provides the essential nutrients that plants need to grow. The most important of these being Nitrogen (N), Phosphorus (P) and Potassium (K). These three elements make up the biggest part of most fertilisers hence why they are called N-P-K fertilisers and each helps the plant in a different way.


Promotes a strong plant and mainly provides nutrition for the shoots and blades and so encourages lush grass growth. Nitrogen also encourages the plant to tiller (send out side shoots) which thickens up the lawn and helps to crowd out moss and weeds.


Gives the plant a strong root base so it can better absorb any available nutrients.


Is extremely helpful for the overall health of the grass; supporting it in the resistance of stress factors like drought, disease, cold weather and general wear and tear.

What else is in a fertiliser?

Supporting micronutrient elements:


Is best known for making grass that deep, rich green that we love; magnesium is an important component of chlorophyll. It is safe and natural and supports seed germination, nutrient absorption and overall plant health.


Acts as a shield between the grass plant’s cells and pathogens like bacteria and viruses. It also encourages the division of cells and helps root and stem growth by stimulating the grass plant’s metabolism and enzyme activity. Calcium can also help maintain the soil’s pH levels, which is essential for a healthy lawn.

Organic elements:

Unlike most lawn care companies we are as organic as possible and use fertilisers that include organic elements which have a huge variety of benefits that go beyond simply feeding grass. One important treatment we recommend for a healthy green lawn is our Organic Bio Booster.

It’s all about timing…

We apply fertiliser to your lawn on 4 out of the 5 treatment visits per year, from spring to autumn but we don’t apply fertiliser as part of the Winter Treatment. Grass won’t be growing efficiently enough during this time of year and would not utilise the nutrients effectively. The fertiliser would simply get washed before the grass plant could absorb it and make use of it.
As a general rule, our Seasonal Treatments are applied every 10 weeks and this is for good reason. If you leave it longer, the fertiliser will be used up or washed away and stop feeding the grass. But if you fertilise too regularly you can scorch the grass with the large amount of nitrogen.

Spring & Autumn fertiliser

A combination of fast and slow-release granules give the grass an instant boost after the long cold months whilst the inclusion of slow-release granules means grass will be fed slowly up to the next treatment, thereby helping to control the growth of the grass but without requiring excessive mowing.
We provide magnesium for colour and calcium for strength.
This fertiliser is ideal after scarification as it will give the stressed lawn a vital nutrition boost it needs.

Early & Late Summer fertiliser

Many standard summer fertilisers use a combination of fast and slow-release granules but this is risky as it often causes a scorched lawn. Our summer fertiliser contains only slow-release granules, which offers a helpful drought-proof element so even if it doesn’t rain for an extended period of time the grass will not be scorched.
