Having an enviable lawn is something that many of us aspire to but cannot always achieve without a little bit of intervention and effort. A lawn is a living thing, and, like all living things, it needs food to grow. Sunshine and rain are not enough to make our lawn flourish. We need to feed it. And this is where the best lawn feed UK stores have to offer comes in.

Lawn feed provides nutrients that are vital for plant growth. Without these extra nutrients, grass will rely on food reserves in the soil, which it quickly uses up. Eventually, we have a pale or patchy, unattractive lawn.

Nitrogen, phosphorus and potassium are essential nutrients needed by lawns and are key ingredients in lawn feeds or fertilisers. Feeding your lawn is a simple but repetitive task once you have found the best lawn feed for your garden. You simply need to decide whether to go for a chemical feed or take the organic approach. Whatever your choice, you will soon be on your way to a lush, healthy lawn, the envy of all your neighbours!

Lawn Feed Reviews – Our Top 10 Picks

Scotts Miracle-Gro EverGreen Complete 4-in-1 (Editor’s Choice)

The EverGreen Complete 4-in-1 lawn feed gives you a lot of lawn care for your money. You apply this granular lawn feed to your grass using a spreader rather than by hand, and it gets to work providing food for your lawn. It can also kill weeds and moss and uses the Scotts Miracle-Gro watersmart formula to help your lawn become drought resistant by helping your grass absorb every drop of water during hot sunny months.

This granular lawn care provides six weeks of slow-release nitrogen into the ground, promoting long-lasting healthy grass that looks greener within just seven days! Additionally, just one bag of this best lawn feed UK will give you a greener lawn on a 400 m² area!

One thing to be mindful of when using this lawn fertiliser is that it is harmful to aquatic life, so you must use it with care if you have a pond in your garden.


  • Feeds your lawn
  • Weed and moss killer
  • Drought resistant
  • It helps grass absorb water
  • Continues to release nitrogen for up to six weeks


  • Harmful to aquatic life
  • May scorch grass if a spreader is not used
  • May mark a patio if the product makes contact with it

Ferromel 20 Ferrous Sulphate Conditioner (Luxury Choice)

This is a lawn feed rich in iron sulphate. It has high quantities of potash and phosphate, which supports rapid growth and root development, enabling better absorption of nutrients.

The Ferromel 20 Ferrous Sulphate Lawn Conditioner is an extremely powerful feed. It promotes strong growth and provides you with a darker green lawn in a short amount of time. Additionally, once applied, it is a very effective moss killer. Within an hour of applying this granular lawn feed, you can begin to see the moss turning black, which will need removing from your lawn once fully dead.

The product comes in mini granules, which are easy to apply. You just dissolve the required amount of lawn feed in water and apply it with a sprayer or sprinkler.

You are advised not to walk on grass that has been treated with the lawn feed until it has rained or been watered, as you could damage the finer grass.


  • Rich in potash and phosphate
  • Moss control
  • Easy to apply
  • Creates a greener lawn
  • Good value for money


  • Contact of soluble lawn feed with patio slabs or decking may cause discolouration
  • Scorching may occur if this product is over-applied
  • Too fine to use with a spreader

6X Natural Fibrous Fertiliser (Best Value)

If organic gardening is important to you, then the 6X Natural Fibrous Fertiliser is a good place to start for feeding your lawn. The lawn fertiliser is a highly concentrated chicken fertiliser and can be used on shrubs and flower or vegetable beds as well as on your lawn.

The lawn fertiliser promotes a healthy lawn by containing nutrients and trace elements and neutral PH levels. It can help prevent waterlogging on heavy soils, and for lighter, looser soils, it can help the earth by retaining moisture.

It is also cost-effective as one bag of the 6X Natural Fibrous Fertiliser, which weighs 15 kg, is equivalent to six to eight bags of farm manure. A small amount of this lawn feed goes a long way as one application will continue to work effectively throughout the season.


  • It is organic
  • Rich in trace elements and all the nutrients your lawn needs
  • Versatile and can be used on all types of soil and grass as well as vegetables and flowers
  • Improves soil quality
  • Easy to apply


  • Produces a smell when used
  • May produce better results on vegetables and plants than on lawns

Westland SafeLawn (Best Pet Friendly)

This is a great option for lawn fertilisers as it contains grass seed and the fertiliser product. This means that new grass seeds begin to grow and out-compete moss and weeds in your lawn, as well as the fertiliser getting to work to improve the quality of the soil.

The lawn food is easily applied using the box provided and then only requires brushing or raking into your lawn. However, if you have pets that may be attracted to the smell of the fertiliser when applied to your lawn, it is best to water it so that the odour is reduced; otherwise, it can be left to break down and be absorbed without watering.

You can be confident applying this organic lawn feed as it contains no herbicides or pesticides and is completely safe for children and pets.

One thing to note is that it is recommended to apply lawn feed every four to six weeks throughout the growing season.


  • Child and pet friendly
  • Made with 100% natural ingredients
  • Transforms dead moss and leaves into nutrients
  • Easy to apply
  • Contains grass seed


  • Requires reapplying every four to six weeks throughout the growing season
  • May release a strong odour
  • Removes weeds and moss by growing more grass rather than by killing them

Plantworks Empathy (Best Liquid)

One bottle of the Plantworks Empathy liquid feed contains sufficient product to fill a watering can up to nine times over. The seaweed extract is made from sustainably farmed kelp and contains a large range of vitamins and amino acids, as well as being further fortified with potassium, phosphorous, iron and nitrogen. These provide your grass with all the essential nutrients it needs for healthy growth and a lush green appearance.

For a regular application, you simply add two capfuls to 4.5 litres of water, and that will cover up to 10 m², or you can use it as and when to give your lawn a boost of colour and health. Additionally, as this is a naturally derived grass food, it is environmentally friendly and child and pet friendly.

Lawn feed products do not necessarily kill off moss, so if this is what you require, this might not be the product for you, but it is great for grass growth.


  • Organic contents make it environmentally friendly
  • Easy to apply with a watering can
  • Has an extensive coverage
  • It makes your lawn greener
  • Child and pet friendly


  • Requires regular application
  • It may not kill weeds and moss
  • It may not be easy to detect the improvement in green colour in your grass

MOOWY Controlled Release (Best All-Season)

One bag of the MOOWY lawn feed is sufficient to cover a 50 m² lawn. It is a slow-release fertiliser that starts to work once it has been applied to your lawn using a lawn spreader and then watered. Magnesium in the lawn food increases photosynthesis in the grass, giving you a greener, more lush looking grass in no time.

This lawn feed is safe for both pets and children to use the grass straight away after application, so there is no need to worry. And unlike other lawn fertilisers, it does not have a strong farmyard odour that will have your neighbours complaining or make it unpleasant to sit out in when you have just applied it.

This is an instant application product, it does not require mixing with water to apply, so it is very straightforward to use and can help to prevent lawn disease and general wear and tear.


  • It only needs to be applied every 90 days
  • Safe for children and pets immediately after application
  • Odour free
  • Difficult to scorch grass by over-application
  • It can be applied directly, no need to mix it with water


  • Requires watering upon application, or it may not work
  • Product instructions may not come in English
  • It may not work to kill moss

Vitax Green Up Liquid Feed and Weed

This lawn weed and feed liquid fertiliser by Vitax kills weeds and encourages new growth in the space left. The high nitrogen level in the liquid lawn feed leaves you with a lush green lawn quickly, which is perfect if you have a BBQ coming up and want to impress friends!

One bottle will cover an area of approximately 200 m², and it only needs to be applied once a year to meet all your lawn needs! In addition, it is easy to use as it simply needs to be diluted and then applied with a watering can or sprayer.

This one lawn feed contains biocides and is harmful to aquatic life, so care needs to be taken when applying it if you have children, pets or a pond in the vicinity of your lawn.


  • Kills weeds
  • High in nitrogen, thereby promoting growth
  • Easy to apply
  • It only needs to be applied once a year


  • It contains biocides that are dangerous for animal and plant life
  • May work better in making grass greener than in killing weeds
  • Only works for weeds that are in leaf at the time of application

Pro-Kleen 2.5 KG Premium Iron Sulphate (Best Soluble)

Unlike other water-soluble lawn feeds, this one comes in powder form and is long-lasting and high in iron sulphate for a dark green lawn. The iron in this lawn feed encourages growth and can also perform as a turf hardener. Additionally, it can be used to prevent disease and kill moss extremely efficiently, turning it black in your lawn within hours, ready for scarification and removal.

The quick-acting powder can be applied directly to your lawn, but it is recommended that you dilute the lawn feed in water and apply it using a watering can or sprayer. The 2.5 kg resealable tub can provide lawn feed for up to 2500 m², which is great value for money.

If you come into contact with this product when applying lawn feed, it can be harmful if ingested and an irritant to your skin and eyes, so it is important to be careful around children and pets.


  • It kills moss and weeds
  • Strengthens lawn
  • Rich in iron sulphate
  • Powder form so goes a long way
  • Works in four days


  • Harmful if ingested or comes into contact with your skin
  • The lawn feed may stain if it comes into contact with surfaces
  • No measuring facility provided with the product

GUARD-EN-FORCE Iron Sulphate Premium

This large 5 kg tub of lawn feed can cover between 2500 and 5000 m² of lawn, and the tub is resealable to keep it in good condition!

Sulphate of iron has the effect of making your lawn lush and dark green and encourages new growth. This is a quick-acting but long-lasting lawn food that can be applied directly to your grass and then watered in but is better diluted in water and distributed using a sprayer or watering can.

Additionally, this lawn feed can work well to reduce worm casts over autumn months, especially during very wet conditions. Finally, if the right results aren’t seen on the first application, it can be applied again with adjusted quantities until your grass looks like a brand new lawn!


  • Can be applied dry or in a diluted solution
  • A large tub which is resealable
  • Conditions and feeds
  • Long-lasting but quick-acting
  • Reduces worm casts


  • May not dilute very easily
  • Quantities for use may need adjusting
  • May stain because of the iron content

Spring and Summer Professional Treatment

The Spring and Summer Professional Lawn Treatment Feed comes in granule form and can be applied easily by hand or using a spreader. The lawn food breaks down quickly, releasing all the nutrients into the soil, making the lawn green and healthy in six weeks. Application is recommended in the main growing season, between April and September.

A fantastic attribute of this lawn food is that it is animal friendly, so it won’t hurt your pets, and you don’t have to keep them indoors as some other lawn feeds require.

The Spring and Summer Professional Lawn Treatment Feed is high in phosphate and potash, two nutrients that encourage harder growth and better root development.


  • Easy to apply
  • Animal friendly so your pets can be out on the lawn
  • Rich in phosphate and potash
  • Quick to break down
  • It does not require diluting


  • It may not be particularly effective against weeds
  • It may scorch your lawn
  • Advertised to come with free grass seed but may not do

Buyer’s Guide

On a basic level, the best lawn feed products are applied to your lawn, and they release essential nutrients into the soil to boost plant food reserves and improve the quality and colour of your grass. It is also possible that they will act to rid you of weed and moss issues in your lawn too. But here, the commonality of products ends. There are many different options for application, ingredients, and what the lawn food achieves, so we have set out some guidance below to help you select the right product for your lawn care routine.

Product Type

The best grass feed can come as granules, powder or liquid, and each has its pros and cons, as we have tried to set out in our lawn feed reviews. Liquid requires the quantities to be worked out and the dilution to be done before you can use it.

Granules or powder take less upfront effort but can smell when applied to your lawn, especially if they are organic fertiliser feeds. If you have pets or children, you also need to ensure that any lawn feed is safe and does not contain biocides.

Whether your best lawn feed is organic or contains biocides is another key decision. Biocides can be harmful to aquatic, plant and wildlife, so it is important to consider where they are being applied. Organic products can be made from seaweed, chicken fertiliser, or other organic matters and are safe to use in a family garden.


There are two main ways that good lawn feed is applied to your lawn, via hand or lawn spreaders or by diluting a soluble lawn food in water and applying it with a sprayer or watering can.

Granular lawn fertilisers tend to need to be watered in once you have spread them evenly over your lawn, and then they will break down and start to release nutrients. They also require you to either use your hand or to have purchased a spreader designed specifically for this job, which is an additional cost. However, it can be used application after application once you own it.

A liquid lawn food requires the effort of working out quantities and diluting upfront, but then once you have sprayed it on your lawn, your work is done. All you require is a hose, watering can, or sprayer.

Additional Features

Several different lawn needs are met by lawn feeds, whether that be one that kills moss or one specifically designed to promote root growth. Weeds and moss can be the bane of a proud gardener’s life, and a product that specialises in being a moss killer is a great item to have in your arsenal!

You may also want a fertiliser that is concentrated enough to only require one lawn feed per year to keep your grass looking lush and dark green rather than other products that need to be reapplied every 4-6 weeks throughout the season. Additionally, some lawn feeds are designed to be quick to break down, whilst others are promoted as being slow release so their benefit can be longer-lasting.

An annoyance that can occur through autumn months especially is worm casts in your lawn, and there are products in our top ten review that are designed to reduce the occurrence of them as they can cause your lawn to become muddy and slippy in wet weather.

Finally, there are some lawn feeds that are mixed with grass seeds so that once weeds and moss are cleared from your lawn, new grass seeds have space to take root and fill the spaces left.


We hope that our top ten reviews and the information provided in our buyer’s guide have provided you with the information you need to decide on the best lawn feed in the UK. But if you are still unsure or struggling to decide, let us recommend our editor’s choice – the Scotts Miracle-Gro EverGreen Complete.

The EverGreen Complete Watersmart formula offers standout protection for your lawn from drought conditions by ensuring that all water is absorbed. It also helps your grass be resistant to heat and other stresses through the warmer months.

It is easy to apply this lawn feed to your garden, and the recommended method is to use a spreader, making sure that the granules are evenly distributed. Another feature that we love about this best lawn fertiliser UK stores have to offer is that it will kill weeds and moss and deliver excellent lawn feeding results.

This granular lawn care provides six weeks of slow-release nitrogen into the ground, promoting long-lasting, lush grass that looks greener within just seven days! Additionally, just one bag of this lawn feed will give you a greener lawn on a 400 m² area!

One thing to be mindful of when using this lawn fertiliser is that it is harmful to aquatic life, so you must use it with care if you have a pond in your garden.

Good luck in making your lawn the envy of all your neighbours!
