What is lawn fertiliser?

Lawn fertiliser is a blend of essential nutrients that provides the nourishment your grass needs to grow vigorously and maintain its vibrant green color. The three key nutrients found in fertiliser are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen promotes leaf growth and green color, phosphorus aids in root development, and potassium enhances overall plant health and disease resistance.

Choosing the right fertiliser

Not all lawns have the same nutritional needs, so it’s essential to select the right fertiliser for your specific grass type and soil conditions. There are three primary types of lawn fertilisers:

1. Granular fertiliser: This is the most popular type of lawn fertiliser. It comes in small, granular pellets that are spread over the lawn using a broadcast spreader or by hand. Slow release lawn fertilisers release nutrients slowly, allowing for a consistent and even application.

2. Liquid fertiliser: Liquid fertilisers are mixed with water and applied using a hose-end sprayer or a watering can. They offer quick nutrient absorption and are ideal for providing a quick boost to your lawn.

3. Organic fertiliser: Organic fertilisers are derived from natural sources such as compost, bone meal, or fish emulsion. They are a popular choice for environmentally conscious homeowners and help improve soil health in the long run.

When choosing a fertiliser, consider factors such as your lawn’s condition, grass type, and the specific nutrient needs of your soil. Conducting a soil test can provide valuable insight into the specific nutrient deficiencies your lawn may have.

Applying lawn fertiliser

Proper application is key to getting the most out of your lawn fertiliser. Here are some essential tips to keep in mind:

1. Read the instructions: Each fertiliser product comes with specific instructions on how much to use and when to apply it. Always follow these guidelines carefully.

2. Timing is everything: Apply fertiliser at the right time for maximum effectiveness. Typically, early spring and autumn are the best times to fertilise lawns. Avoid fertilising during hot summer months or periods of drought, as it can stress the grass.

3. Use a spreader: For granular fertilisers, use a broadcast spreader to ensure even coverage over the entire lawn. Walk at a steady pace and apply the fertiliser in a crisscross pattern to avoid streaks or uneven distribution.

4. Water after application: After applying fertiliser, water your lawn lightly if rain is not expected within the next day or two. This helps activate the fertiliser and encourages nutrient absorption.

5. Don’t overdo it: Applying too much fertiliser can harm your lawn and even lead to nutrient runoff, which can be harmful to the environment. Follow the recommended application rates and avoid excess.

Maintaining a healthy lawn

While fertiliser is essential for a vibrant lawn, it should be part of a comprehensive lawn care routine. Regular mowing, proper watering, and control of unwanted weeds are equally vital. If possible, try to aerate your lawn annually to alleviate soil compaction and allow nutrients to penetrate deeper into the root zone.


Lawn fertilisers are a game-changer when it comes to achieving a stunning, green lawn. By understanding the different types of fertilisers, applying them correctly, and maintaining an overall lawn care routine, you can achieve an attractive lawn. So, grab your spreader, choose the right fertiliser, and get ready to enjoy a lawn that will make your neighbors green with envy!

Additional Questions
How often should I fertilise my lawn each year?

The frequency of fertilisation largely depends on the type of fertiliser you use and the specific needs of your lawn. Generally, a lawn benefits from being fertilised 2-4 times a year. A soil test can offer more precise guidance by identifying nutrient deficiencies.

Can lawn fertiliser improve soil quality?

Yes, especially organic fertilisers, which not only feed the grass but also contribute to the overall health of the soil. They improve soil structure, encourage beneficial microbial activity, and can help with water retention.

Should I change fertilisers between seasons?

Seasonal changes in weather and grass growth rates can affect the nutritional needs of your lawn. Using a nitrogen-rich fertiliser in the spring can kickstart growth, while a phosphorus-rich mix in the fall can help prepare the lawn for the winter.

How do I handle fertiliser burn on my lawn?

Fertiliser burn can occur if too much is applied. If you notice signs of burn, such as yellowing or brown patches, water the affected area thoroughly to dilute the concentration of fertiliser in the soil. In severe cases, reseeding may be necessary.

Is it safe to use around pets and children?

While many lawn fertilisers are safe once properly applied and settled, it’s always best to choose pet and child-friendly options when available. Always follow the application instructions and allow the lawn to dry or be well-watered before allowing pets and children to play on it.

What role does pH play in fertilisation?

Soil pH can significantly affect nutrient availability to your lawn. A soil test can reveal your soil’s pH level, allowing you to adjust it with the appropriate fertilisers or soil amendments to ensure optimal nutrient uptake.

Can I use a weed and feed product as my regular fertiliser?

Weed and feed products combine fertiliser with weed killer. While convenient, they should not replace your regular fertilisation routine unless weeds are a consistent problem. Overuse can lead to excessive chemical buildup in your soil.

Incorporating these considerations into your lawn care routine, alongside the basic guidelines on choosing, applying, and maintaining with fertiliser, can significantly enhance the health and beauty of your lawn, creating a lush, green oasis for you to enjoy.
