What are lawn fertilizers?

Lawn fertilizer 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 fertilizer products provide grass with these essential nutrients, which are difficult to obtain naturally. Lawn fertilizers 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 fertilizer?

While most lawns don’t necessarily need fertilizers, using one certainly improves the overall health and appearance of your lawn. For example, applying a lawn fertilizer 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 fertilizer on poor-quality lawns helps restore the appearance, encouraging thick, vibrant growth.

How to choose the right lawn fertilizer?

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

  • Granular or Liquid: There are two main types of lawn fertilizer – granular and liquid. Granular lawn fertilizer offers slow-releasing nutrients that feed lawns over a longer period, often several months. These are the best lawn fertilizers for people who want a low-maintenance way to feed their grass. Liquid fertilizers are mixed with water and applied to a lawn, usually via a watering can. These lawn fertilizers are fast-acting, providing results almost immediately. If your lawn is in poor condition and needs a quick fix, then liquid fertilizers are the best choice.
  • Ingredients: All lawn fertilizers 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 fertilizers with equal amounts of NPK are considered great all-purpose lawn fertilizers. Feeds with higher nitrogen encourage thick, green grass to grow quickly. Fertilizers high in phosphorus are best suited for newer lawns, as this encourages strong root development.
  • Frequency of Use: Some lawn fertilizers 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 fertilizer 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 fertilizer in the UK?

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

  • Granular Lawn Fertilizers: This fertilizer 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 Fertilizers: This fertilizer 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 fertilizer burn if you use too much product and consequently over-fertilize some areas of your lawn.
