What lawn fertiliser should I use?

With so many types of lawn fertiliser available we though we would help to answer the question of which lawn fertiliser to use. Did you know that your lawn is the only plant in your garden that you cut over 20 times a year. The grass that we mow is actually the result of this incredible plant photosynthesising and removing nutrients from the soil.

Our grass is constantly walked on, played on and generally subjected to allot of wear compared. So using the right lawn feed/fertisliser at exactly the right time will help replace lost nutrients as well as keep weeds and moss at bay. It will also help your lawn recover from winter.


Which lawn fertiliser is best for all lawns?

The best type will actually change throughout the year. Therefore, it’siportant to make feeding your lawn part of the seasonal process of caring for your lawn.

We recommend using a lawn spreader to ensure even coverage. Check out our lawn spreader settings here.


Lawn fertiliser for early Spring

Choose one with high Nitrogen levels as it will encourage new growth. Using Westland SafeLawn is ideal for this season. Use from February to September.

Lawn fetrtiliser for Spring and Summer

Usually with a higher nitrogen content to encourage leaf and shoot growth. It’s best to use this from March to September and it will steadily release nutrients over a 6-8 week period.

Either choosing Westland SafeLawn (Use from February to September) or Aftercut All In One is a good option for these months. Use during the months of May to August. This all in one product, not only feeds, but greens and controls weeds.

Lawn fertiliser for Autumn 

At the end of the growing season we recommend using something like Aftercut All In One Autumn. Use this from September to mid November.

aftercut all in one autumn

It is specially formulated to provide nutrients throughout this period. It helps to control moss as well as keeping your lawn healthy and strong over the winter months.

Fertilising a lawn when you have kids and pets

If you have children or pets, or both, it’s important to consider child and pet friendly lawn care. Try to ensure an even coverage, we recommend using a lawn spreader. Our child and pet friendly range includes:

Should I use liquid or granular lawn fertiliser?

Granular fertiliser release nutrients over approximately 6-8 weeks for a slow and steady supply of nutrients. Whereas, a liquid fertiliser works much faster, that can work in only 2-4 weeks.

What do lawn fertilisers contain?

Fertilisers contain 3 primary nutrients:

Nitrogen (N) As plants cannot absorb the nitrogen from the air, this nutrient has to be absorbed via soil. It forms part of the chlorophyll, that beautiful green colour, therefore it is essential for photosynthesis. (The process by which plants use sunlight, water and carbon dioxide to create oxygen and energy.)

Phosphorous (P) assists the grass growth. It also encourages root growth. Remember, excessive use can lead to a build up of thatch so always follow the application rate advised on the box carefully.

Potassium (K) controls the stomata (cell structures in the epidermis involved in the exchange of carbon dioxide and water between plants and the atmosphere). Therefore, water loss within the plant can affect the drought tolerance of your lawn.
