The 10 best lawn fertilisers to buy in the UK

Picture of a lawn fertiliser

Maintaining the perfect lawn is harder than most think. Your lawn needs a surprising amount of care and attention, including regular mowing, aerating, and feeding. The best lawn fertiliser is essential for a healthy, vibrant lawn with thick growth and minimal weeds. Whether your lawns are in great condition or are dull and patchy, it’s a good idea to use a quality lawn fertiliser. However, with so many products to choose from, finding the best lawn fertilisers is often challenging! Check out our handy buying guide below for all the info you need to find the right fertiliser for your lawn.

What are lawn fertilisers?

Lawn fertiliser is a garden product that provides added nutrients for your grass. All plants need a balance of nitrogen, phosphorus, and potassium (NPK), for strong, healthy growth. Lawns are no different, needing a unique balance of NPK to encourage optimal growth throughout the year. The best lawn fertiliser products provide grass with these essential nutrients, which are difficult to obtain naturally. Lawn fertilisers are sold in both liquid and granular forms, while products can target specific things like patchy lawns, new lawns, and summer growth.

Why should you buy a good lawn fertiliser?

While most lawns don’t necessarily need fertilisers, using one certainly improves the overall health and appearance of your lawn. For example, applying a lawn fertiliser high in potassium at the start of the growing season in spring encourages healthier growth, resulting in much greener grass. Of course, sometimes lawns aren’t in good condition, especially after a long winter with extreme temperatures and poor weather. These lawns may be dull, patchy, and covered in weeds. Using the best lawn fertiliser on poor-quality lawns helps restore the appearance, encouraging thick, vibrant growth.

Are you struggling to find the best lawn fertilisers for your garden? Here are some things to look out for when buying a lawn fertiliser:

  • Granular or Liquid: There are two main types of lawn fertiliser – granular and liquid. Granular lawn fertiliser offers slow-releasing nutrients that feed lawns over a longer period, often several months. These are the best lawn fertilisers for people who want a low-maintenance way to feed their grass. Liquid fertilisers are mixed with water and applied to a lawn, usually via a watering can. These lawn fertilisers are fast-acting, providing results almost immediately. If your lawn is in poor condition and needs a quick fix, then liquid fertilisers are the best choice.
  • Ingredients: All lawn fertilisers have the chemical ingredients nitrogen, phosphorus, and potassium. Be sure to check the NPK ratio of the lawn feed, as the balance of ingredients impacts how it affects the lawn. For example, lawn fertilisers with equal amounts of NPK are considered great all-purpose lawn fertilisers. Feeds with higher nitrogen encourage thick, green grass to grow quickly. Fertilisers high in phosphorus are best suited for newer lawns, as this encourages strong root development.
  • Frequency of Use: Some lawn fertilisers need to be applied more often, which some people would rather avoid. For example, if you don’t want to regularly feed your lawn, then a granular fertiliser is the best choice. It’s slow releasing, lasting weeks or even months, so won’t need to be applied too frequently. Liquid feed requires more frequent application, while you need to spend time mixing it with water and applying it to the lawn.

What is the best kind of lawn fertiliser in the UK?

Unsure what type of lawn fertiliser is best for your needs? Here are the main options available:

  • Granular Lawn Fertilisers: This fertiliser has small granules that are applied directly to the lawn. These granules slowly release nutrients over weeks and months. It’s a great lawn feed for a hands-off gardener, requiring little effort while leaving you with a healthier lawn.
  • Liquid Lawn Fertilisers: This fertiliser comes in a liquid form that is diluted with water and then applied to the lawn. It’s fast-acting, providing results almost immediately, making it especially good for lawns in poor condition. However, there is a risk of fertiliser burn if you use too much product and consequently over-fertilise some areas of your lawn.
