Liquid Fertilisers for Your Lawn 

Lawn fertiliser helps to keep your lawn healthy and green. Fertilisers can help replenish any lacking nutrients and encourage strong grass growth.

It is not only the aesthetics of your lawn that fertiliser can improve, as the lawn is in a healthier condition, fertiliser can help a lawn recover from wear and tear and harsh weather conditions.

The best lawn fertiliser (also known as lawn feed) depends on your lawn type and condition.

Most fertiliser comes in either granular or liquid forms. Liquid form fertiliser is often easy to apply to a lawn and presents results quickly.

With so many fertilisers on the market, it can be overwhelming knowing which is the best liquid lawn fertiliser for you.

What Liquid Fertiliser is Best for Lawns?

The best liquid fertilisers will contain a mixture of nutrients, but you should especially look for nitrogen, potassium, and phosphorus as base ingredients.

Be careful when using fertilisers with high levels of nitrogen, these fertilisers provide quick visual results but aren’t sustainable

Often the nutrients in a fertiliser will be written as N-P-K, which stands for nitrogen (N), potassium (K), and phosphorus (P).

Each of these letters will be accompanied by a number, the number indicates how many parts of the nutrient are in the liquid fertiliser.

Which liquid fertiliser is best for a lawn depends on the needs and requirements of the lawn.

Considerations will include how quickly you need to produce results, the size of the lawn, soil quality, type of grass and equipment needed to spray the fertiliser.

Why Liquid Lawn Fertiliser is a Good Choice for Your Yard

Nutrient Source

Some fertilisers will have added synthetic chemicals to add nutrients, whereas others add nutrients from natural sources such as plant extracts.

Organic fertilisers with natural nutrient sources are better for the health of the soil and grass, they are also better for the environment.

Lawn Size

The best choice for a large lawn is spraying liquid fertilizer. Spraying fertiliser ensures a more even coverage, it also saves money as a more cost-effective lawn care option.

If cost is important, liquid fertilisers from concentrate are the most affordable as a little can go a long way. 


For quick results, you should choose a high-nitrogen liquid fertiliser. High-nitrogen liquid fertilisers provide results in a few days, but be careful as these aren’t suggested for long-term use.

Consider how much time and effort you want to put into fertilising your lawn. Not all liquid fertilisers come ready to use. Some liquid lawn feed will come concentrated, which means you will have to mix the appropriate portions into secondary application equipment before spraying.

When Should You Apply Liquid Lawn Fertilizer?

One of the advantages of liquid lawn fertiliser is that you can apply it immediately. This fertiliser can advance the growth of grass seeds.

The benefit of fertilising immediately is that not only do the seeds sprout quicker but they also develop stronger roots.

For a pre-existing lawn, the best time to apply liquid lawn fertiliser is after the first mowing in spring.

You should fertilise at this time because it encourages active, green growth that lasts the entire summer.

How to control Summer Grass

It also prevents weeds from popping up, by encouraging grass to grow before unwanted plants germinate.

After this application, the next time to apply the liquid fertiliser is early fall, this will help the lawn combat the winter’s freezing conditions.

Liquid lawn fertilisers should be applied to a lawn two times a year. Bi-annual applications are the best way to maintain luscious grass growth with healthy roots.  

How Much Liquid Lawn Fertilizer Should You Apply?

There are plenty of fertilisation tools to help ensure your lawn gets an even coverage

Using a spray bottle for liquid fertiliser means no section gets more fertilised than another

A uniformly fertilised lawn benefits the grass.

Applying too much fertiliser and too little fertilizer in one section will lead to a patchy lawn.

Instead of a luscious green lawn, you will have brown patches from over fertilisation, these patches will be contrasted by emerald green patches where the grass has been treated properly.

How much fertiliser to put in the spray bottle is another question and depends on a number of things.

The condition of the lawn, the type of grass laid, and the manufacturer’s instructions.

Before either application, in spring or fall, you have to measure the fertiliser concentration precisely.

How to Apply Liquid Fertiliser to Your Lawn

Evenly spreading fertiliser can be difficult, but spraying liquid fertiliser is far easier than granular lawn feed. An even application is imperative to a good looking lawn. Liquid fertiliser can be applied using a garden hose attachment, most liquid fertilisers come prepared with a garden hose attachment.

How Long Will Liquid Fertiliser Last?

For most lawns, an application twice a year is all that is needed. An application in Spring will last then until Fall. 

The Spring application encourages strong growth for the Summer, then the Fall application boosts the nutrients of the soil to help the lawn survive the winter.

In storage, fertiliser can last for years – up to 10 years – however, proper storage is key to ensure this longevity.

Without proper storage, fertiliser can begin caking, leaking and in some instances can become hazardous. 

Is Liquid Fertiliser Better than Granular Fertiliser?

The primary nutrient content is the same in both liquid and granular fertilisers, the main difference is how the nutrients are delivered. 

The main disadvantage of liquid fertiliser is that incorrect application of applying too much can burn and damage your lawn.

The main advantage is that liquid fertilisers have a more significant spatial difference, this means that the fertiliser is more mobile allowing it to better nourish grass roots.
