When it comes to keeping your lawn healthy and green, using the right amount of fertiliser is key. But how much lawn fertiliser does your lawn really need? This question can be tricky, especially with all the different types of fertilisers and recommendations out there. Let’s break it down in simple terms.
Understanding lawn fertiliser
First off, let’s talk about what lawn fertiliser actually is. Fertiliser is a mix of nutrients that help plants grow. It usually contains nitrogen, phosphorus, and potassium, which are the three main nutrients your grass needs. Nitrogen helps your grass grow big and green. Phosphorus helps with root growth. Potassium helps your lawn deal with stress and disease.
Why fertilising is important
Fertilising your lawn is important because it gives your grass the extra nutrients it needs to stay healthy. Over time, nutrients in the soil can get used up or washed away. By adding lawn fertiliser, you’re giving your lawn a boost, helping it grow strong and look great.
How much fertiliser does your lawn need?
The amount of lawn fertiliser your lawn needs depends on a few things, including the type of grass you have, the soil quality, and the time of year. Let’s look at these factors in more detail:
1. Type of grass
Different types of grass have different needs. For example, cool-season grasses like ryegrass or fescue often need more fertiliser in the spring and fall. Warm-season grasses like buffalo grass or kikuyu usually need more fertiliser in the warmer months. It’s a good idea to know what type of grass you have to get the best results from your lawn fertiliser.
2. Soil quality
The quality of your soil plays a big role in how much fertiliser your lawn needs. If your soil is rich and healthy, you might not need as much fertiliser. But if your soil is poor or lacking in nutrients, you may need to use more lawn fertiliser. You can test your soil to find out what nutrients it’s missing. Soil tests are available at garden centres or online, and they can give you a good idea of what your lawn needs.
3. Time of year
The time of year also affects how much fertiliser your lawn needs. In Australia, you should generally fertilise your lawn about once every 6 to 8 weeks during the growing season. For cool-season grasses, like those found in southern regions, this usually means autumn and early spring. For warm-season grasses, common in northern areas, it’s often late spring and summer. Try to avoid fertilising in the winter months when grass growth slows down.
How to apply lawn fertiliser
Applying lawn fertiliser properly is just as important as using the right amount. Here are some tips to help you apply it correctly:
Always read the label on your lawn fertiliser.
It will tell you how much to use and how often. Different fertilisers have different instructions, so follow them closely for the best results.
Use the right spreader.
A lawn spreader helps you apply fertiliser evenly. There are two main types: drop spreaders and broadcast spreaders. Drop spreaders drop the fertiliser directly beneath the spreader, while broadcast spreaders throw it out in a wider pattern. Choose the right type for your lawn and follow the instructions for even application.
Don’t overdo it.
Using too much lawn fertiliser can harm your grass and the environment. It’s better to use a little less than to over-fertilise. If you’re unsure, start with a smaller amount and see how your lawn responds.
Water your lawn.
After applying fertiliser, water your lawn thoroughly. This helps the fertiliser soak into the soil and reach the grass roots. Watering also helps prevent the fertiliser from burning your grass.
Common mistakes to avoid
Using too much lawn fertiliser can cause your grass to grow too quickly, which can lead to other problems like thatch buildup or disease. Stick to the recommended amount and avoid the temptation to use more.
Applying lawn fertiliser at the wrong time can be wasteful or harmful. For example, fertilising during a drought can lead to runoff and pollution. Make sure you’re fertilising during the right season and conditions for your grass type.
Fertiliser alone isn’t enough if your soil is in poor shape. Make sure to improve your soil quality by adding organic matter like compost. This will help your grass make the most of the fertiliser you apply.
How to choose the right lawn fertiliser
There are many types of lawn fertiliser available, including granular, liquid, and slow-release. Each type has its own benefits:
Granular fertiliser
Granular fertiliser is easy to apply and works slowly over time. It’s great for giving your lawn a steady supply of nutrients. It’s often used for general feeding and can be applied using a spreader.
Liquid fertiliser
Liquid fertiliser works quickly and can be applied directly to your grass. It’s useful for giving your lawn a quick boost, but it often needs to be applied more frequently than granular fertiliser.
Slow-release fertiliser
Slow-release fertiliser feeds your grass over a longer period, reducing the need for frequent applications. It’s ideal for maintaining steady growth and reducing the risk of over-fertilising.
