Fertilising Your Lawn - Beginners Guide

Fertilising Your Lawn - Beginners Guide

With every day that passes, your lawn has a little less of the nutrients it needs to stay healthy. If you don't replace these much-needed nutrients, your lawn will decline over time!


What Are Fertilisers?

Fertilisers are a combination of chemicals that when added to soil or land increase fertility. The main chemicals that can be found in fertilisers are usually nitrogen, phosphate, and potassium, these are more commonly known as N.P.K numbers, which can be found on all of Ivisons labels.

It's important to use different fertilisers throughout the year, as your lawn requires different nutrients in certain seasons. During the spring and summer months, you should look for a fertiliser that has higher levels of nitrogen, as this will promote growth and allow your grass to thrive. During winter months, it's important to use a fertiliser with increased levels of phosphate and potassium as this will encourage the roots to strengthen and grow. 


Why Should I Fertilise My Lawn?

Fertilising your lawn helps:

  • Prevent weeds
  • Prevent moss
  • Prevent diseases
  • Encourage healthy growth
  • Aid root development
  • Improve the colour of the grass
  • Speed up rate of recovery


Not only does feeding your lawn with the correct nutrients help all the above, but it also helps you save a little extra cash as you won’t have to folk out to fix issues caused by low nutrient soil, such as, killing moss, or worse, having to replace your whole lawn.


When Should I Fertilise My Lawn?

At the very minimum you should be fertilising your lawn twice a year. The first application should take place in spring and the second in autumn/winter. An extra application can be applied mid-summer to boost your lawns colour and help protect it against drought.


  1. Spring Application – Required

The first application typically takes place around March/April. It’s suggested that the grass has resumed growth and temperatures are around 8-10 degrees, before applying fertiliser.  


  1. Mid-Summer Application – Optional

Many people opt for a mid-summer application, usually around July to green up their lawn and help improve resilience during the hotter months.


  1. Autumn/Winter Application – Required

The last application of the year usually takes places between September and October to prepare your lawn for the harsh winter months.


What Fertiliser Should I Use?

Firstly, if you’re seeding a new lawn, we recommend using a pre-seed fertiliser. Ivisons 6-9-6 Pre-Seed Lawn Fertiliser is generally the best fertiliser to use prior to sowing.
