Feeding a lawn

Feeding a lawn

A lawn treatment or a lawn feed helps to keep your grass in great condition through each seasonal period of the year. It feeds the roots and the leaves ensuring the plant has the nutrition required for optimum growth.

There are two types of feed for lawns. Liquid feeds which are sprayed onto a lawn and granular feeds which are spread using a spreader in a pelletised form. Sometimes you may purchase feeds in a powder form but they are difficult to apply correctly.

Which you choose to use depends upon the site and soil or how you wish to manage your space both have advantages and disadvantages. The pellet or liquid is simply the carrier of the nutrients which are usually bound by salt so be careful how and where you store your fertilizer.

Its important to match your feed to the soil type, ph level and current condition of your grass plants.

Types of feed

There are generally two types of feed they are slow release or quick release meaning how quickly they are available to a plant and vary upon how long they last. Quick release feeds are generally cheaper than slow release feeds. The components that make up the feed generally consist of N:P:K Nitrogen, Phosphate and Potassium. Feeds vary in quality by what they are made from and the amount of components within them. The better the feed the more expensive it is.

A feed with a high nitrogen content will provide quick growth, but too much will create a weaker plant that is vulnerable to disease. Phosphorous is required for root growth but needs to be managed as most soils contain more than enough. Potassium plays a vital role in healthy grass growth and disease resistance.

Other than N:P:K there are many other elements such as Iron, Calcium, Magnesium, Manganese. Sulphur.

Granular slow release

Slow release fertilizers tend to take time to become available to the plants so will sit around within the grass sward and feed the lawn for long periods. In some cases, especially periods of high temperature feeds can scorch the tips of the grass leaves unless specially designed not to. If they are not drought resistant the feeds must be watered in to avoid scorching.

Quick release

Quick release fertilizers tend to look like cat litter such as the one displayed with this article. They break down very quickly on contact with water, are cheaper than slow release feeds and very useful when you need to make nutrient available quickly. But will run out and leach from the soil more quickly than a slow release. You must water in quick release feeds otherwise they will scorch the lawn.


With liquid fertilizers again there are varying types some are long lasting some are not so long lasting. The purpose of liquid feed is to give the plants exactly what they are missing or unable to uptake from the roots. The feed goes straight into the plant through the leaf. Which means there is no leaching or run off that may otherwise contaminate other spaces.

Bio Stimulants

Bio feeds are designed to feed the life in your soil and living organisms in your lawn. They tend to be full of macro and micro elements. They are essential to counter act the salt content that is within every lawn feed. And boost the bio diversity within your lawn.

When to feed

How often and when to feed your lawn very much depends upon the results you are looking for. If you are on a budget you may feed your lawn twice in a year. When the plants can make the most use so spring and summer. If you are after a green lawn year round you would aim to feed spring, summer, autumn, winter so four times. If your after an intensively manicured lawn then six feeds would be required. Early/Late spring, Early/Late Summer, Autumn, Winter.
