Fertilsing is an essential part of lawn maintenance, encouraging growth and healthy grass all year long. We suggest doing it twice a year – once in the autumn months to protect it throughout the winter and once in spring to help boost the growth and carry you through the summer months.

The first thing you need to do is work out what type of lawn you have, as this will make a difference with which products you use. Common types of grass include Kikuyu, Tall Fescue, Couch and Buffalo.

1. Choose from chemical or organic lawn care

There are two types of lawn care – chemical and organic. A chemical lawn builder gets instant growth and helps green up your lawn while organic fertilisers are eco-friendly and help with your soil’s overall health.

There are also two types of application – liquid and pellets. Liquid tends to absorb quickly, whereas the pellets break down over a period of time. Using one over the other depends on what type of gardener you are – pellets allow you to sit back and let the process happen, meaning a more hands-off approach. Liquid does require a little more regular maintenance but delivers quick results.

It’s also important to check if your ground is hydrophobic before choosing your fertiliser. The best way to check is to see what water does when applied – if it is hydrophobic, the water will pool on the surface or run completely off. You may need to use a wetting agent on your grass, prior to fertilising, if this is the case.

2. Use a lawn spreader to evenly distribute your fertiliser

When using fertiliser, use a lawn spreader so you get a nice even coverage. First, pop on your gardening gloves. Then, adjust the spreader setting as indicated on the back of the pack and in line with the size of your lawn. Fill the tray with fertiliser and then walk at a steady pace, turning the handle as you go so it evenly spreads it over your lawn.

3. Water in the fertiliser using tonic

After you have distributed the fertiliser, it’s a good idea to water it in. Use a tonic or concentrate with your water. Just clip the bottle to the end of your hose and you’re ready to go!

Tip

If you’re using pellets, fertilise your lawn every 3–4 months. If you’re using a liquid, it’s every 1–2 months. If you’re unsure, check the back of the packaging of the product you’re using – it will have a guide.
