Lawn fertilizer can serve different purposes such as killing weeds and mosses, treating nutritional deficiencies, fighting soil stresses etc.
All of these characteristics depend on the composition or formula of the fertilizer. Killing weeds and mosses permanently isn’t possible so you always need a follow-up session to keep the lawn free from weeds and mosses.
On the other hand, if you want to treat the nutritional deficiencies to grow a thicker and greener turf, an extend-release granular fertilizer will do the job in one hit. But in order to treat the lawn with the right combination of NPK, you have to identify the deficiency of a particular element.
We will discuss this in the buyer’s guide at the end of this article.

Buyer’s Guide for Best Lawn Fertilizer UK
If you have decided to go for a lawn fertilizer then hang on a bit, and understand some of the basic things that you must take into account before placing an order.
What is NPK?
For sure, you must have noticed the N-P-K value mentioned on the fertilizers package. Let’s break it down for you. It is a short reference to Nitrogen-phosphorus and Potassium.
Nitrogen helps the grass to stay green and healthy, Phosphorus provides strength to roots and enhances the overall root building process while Potassium helps the plants to fight drought, heat and other stresses. Based on this NPK value, you can determine what formula suits your lawn.
In other words, you can first diagnose the problem of your soil and then choose the right medicine i.e a lawn fertilizer. Moreover, other essential nutrients also play a vital role e.g Iron can treat your pale and yellow grass turn green but the main formula to be focused on is NPK.
Nature of your lawn soil and grass
It is the first step to prescribe the right fertilizer for your garden or lawn. So what is it? Understand your soil and do a soil test (usually every two-three year) in any nearby soil testing laboratory. It will give you the nature of the soil i.e pH and nutrients facts. Based on this diagnosis, you can select the right combination of N-P-K and other additives to address nutritional deficiencies. A blind application may not work and you will blame the product.
Granular Fertilizer vs Liquid Fertilizer
Granular fertilizers are mostly spread with the help of a mechanical spreader for even distribution. Most of the lawn fertilizers these days are in granular form. There are two types of dry granular fertilizers.
- Quick-release granules: Also known as water-soluble nitrogen (WSN). It releases the nitrogen content quickly to feed the lawn. On average, this kind of fertilizer stays for three to four weeks but can vary depending on the weather conditions.
- Slow-Release granules: These are known as water-insoluble nitrogen (WIN). they are further divided into two types, based on the coating which makes them extendedly released form. Polymer-coated granules are more sustainable and can last for 12 weeks while sulfur-coated granules can provide nutrients for eight weeks at least.
On the other hand, Liquid fertilizers are fast-acting and you will be required to apply it every two to three weeks for better results. They may be concentrated or diluted, so a conc-liquid fertilizer should be diluted according to your need and mentioned guidelines. Liquid fertilizers are mostly used for raised beds and containers, however, you can use them in lawns as well.
Organic or Synthetic?
Organic fertilizers have natural sources for its making i.e Peat moss, bat guano, fish emulsion, compost, cottonseed and blood or a bone meal etc. unlike synthetic the results take few weeks to appear as they work on a slow pace but there is no environmental threat with them.
Synthetic fertilizers are manufactured from different minerals, gases and other supporting waste sources. Synthetic fertilizers yield quick results. If you use it in slight overdose it may burn your grass, so you need to be accurate with the formula. There is an environmental threat if they make their way to the local water.
There are different fertilizers based on their mechanism of actions and numbers of application per year. If you are using a fertilizer which mainly focuses on weeds and moss killing, you would probably need multiple sessions every 4-6 weeks. There are fertilizers which are specifically formulated for the autumn season to help the lawn withstand the harsh climate of winter which needs two applications between Sept- Nov.
If you want something to maintain the nutritional values, choose a slow-released dry granular form to avoid multiple applications. One way or another, always follow the maintenance level accordingly to have a thick, green and healthy lawn.
If you are struggling with weeds and mosses and looking for a suitable fertilizer, choose Miracle-Gro complete 4in 1 for a weedless greener and thicker lawn. But in case you want a pre-seeder fertilizer to help the new lawn grow overnight, go for A1Lawn Pre-seeder Fertilizer which has a great reputation in germination and fast root’s building process.
That being said, you are still required to do your calculations by cross-matching the features of fertilizer with the problems you want to address. We hope this guide was helpful for you in understanding the right product for your lawn.
