Green Up Your Lawn: A Guide to Choosing the Best Fertiliser

One of the key ways to improve the colour of your lawn is by using the right fertiliser at the right time. But with so many options available, it can be tough to know which one is right for you. In this article, we’ll answer some of the most common questions about lawn fertilisers.

When to Fertilise Your Lawn

One of the most common questions about lawn fertilisers is when to use them. The answer to this question depends on where you live and what type of grass you have. In general, it’s best to fertilise your lawn when the grass is actively growing, which is usually above 6 degrees Celsius. However, the optimum time to apply a granular fertiliser is just before active growing conditions. The grass plant needs warmth, water and nutrition so when the warmth and water are expected it is the time to deliver fertiliser. This will give it the nutrients it needs to grow strong and healthy.

What Type of Fertiliser to Use

When it comes to choosing a fertiliser for your lawn, there are a few things to consider. The first is the type of soil you have. Different types of soil will have different properties and available nutrient levels, so it’s important to choose a fertiliser that is specifically designed for your type of soil.

The second thing to consider is the type of fertiliser itself. There are two main types of fertilisers: liquid and granular. Within the liquid or granular fertiliser you may choose to use either controlled release, quick release, organic or synthetic. Synthetic fertilisers are made from chemicals, while organic fertilisers are made from natural ingredients. Organic fertilisers often don’t get the results that chemical fertilisers do but some people prefer the more environmental nature of the organics.

Liquid fertilisers are often very quick acting as they are moved through the plant from the leaf or root drench, however, they will only last a maximum of a couple of weeks. Controlled-release fertilisers will be reacted by warmth and water and can last up to many months, ensuring the grass plant has all the nutrients it needs. Quick-release granular fertilisers will often need watering directly afterwards as they tend not to have the coated prill which holds the nutrient release back. This means that the salts in the fertiliser are able to “burn” the grass leaf if left too long without water.

Are Lawn Fertilisers Safe for Dogs?

If you have a dog, then you may be wondering if lawn fertilisers are safe for them. The answer to this question depends on the type of fertiliser you use. Synthetic fertilisers can be toxic to dogs if ingested, so it’s important to keep your dog away from your lawn for a few days after applying the fertiliser. If you use a very small prill this often works its way to the soil surface quickly and is therefore unavailable for pets to get to.

Organic fertilisers, on the other hand, are generally considered to be safe for dogs. However, it’s still a good idea to keep your dog away from your lawn for a few days after applying the fertiliser, just to be on the safe side.

What Lawn Fertiliser is Safe for Dogs?

If you want to use a fertiliser that is safe for your dog, then you should choose an organic fertiliser that is made from natural ingredients. Look for a fertiliser that is labelled as pet-friendly, and make sure to follow the instructions carefully to ensure that it is applied safely.


Choosing the right fertiliser for your lawn is an important step in keeping it healthy and looking its best. Consider the type of soil you have as this will help you determine which fertiliser and what method of application to use before making your decision. Always follow the instructions carefully to ensure that your lawn is fertilised safely and effectively.
