What to Look for in a Lawn Feed

Before we get into the individual reviews, it’s worth understanding a few basics. Every lawn feed has an NPK ratio printed on the packaging. This tells you the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the mix. For spring and summer, you generally want a feed that’s high in nitrogen, as this is what drives green leafy growth. Phosphorus supports root development, and potassium helps your grass cope with drought and foot traffic.

You’ll also want to think about whether you need a simple feed or a multi-purpose product that includes weed killer or moss control. If your lawn is relatively weed-free, a straight fertiliser is usually better value and less stressful for the grass. If dandelions and clover are taking over, a 4-in-1 product can save you time and effort.

Finally, consider your household. If you have young children or pets, a natural or organic feed is the safest choice, as many conventional weed-and-feed products require you to keep people and animals off the lawn for a period after application.

Detailed Reviews

1. Miracle-Gro EverGreen Complete 4-in-1

Type: Granular | Coverage: 80–500m² (depending on bag size) | Price: Around £15–£35

There’s a reason this is the UK’s best-selling lawn care product. The EverGreen Complete 4-in-1 feeds your lawn, kills weeds, controls moss, and promotes thicker growth – all in a single application. It’s high in nitrogen and potassium, so you’ll typically see a noticeable improvement within a week.

The granules are easy to spread by hand or with a wheeled spreader, and the 200m² bag suits most medium-sized gardens. Where it really shines is in lawns that have been neglected over winter – the weed and moss control gives you a visible clean-up alongside the feed.

Pros: Genuinely effective weed and moss control; good coverage per bag; widely available at B&Q, Amazon, and most garden centres

Cons: Not suitable for newly seeded lawns; you need to keep pets off for a few days after application; won’t work well in very dry conditions without watering in

Best for: Gardeners who want a one-stop solution for feeding and tidying up a weedy lawn

2. Miracle-Gro EverGreen Fast Green

Type: Granular (also available as liquid) | Coverage: 80–200m² | Price: Around £8–£18

If your lawn just needs a colour boost rather than a full weed treatment, Fast Green is an excellent choice. It’s a straightforward lawn food with added iron that delivers a noticeably deeper green in as little as three days. Several reviewers – including a professional groundsman – have praised its speed and value for money.

The granular version comes with a handy spreader in the 80m² box, making it particularly convenient for smaller lawns. There’s also a liquid spray version if you prefer that method of application. It’s child and pet friendly, so there’s no waiting period after use.

Pros: Extremely fast results; child and pet friendly; good value; available in both granular and liquid formats

Cons: Contains no phosphorus, so won’t help with root development; no weed or moss control; results fade faster than slow-release feeds

Best for: A quick green-up before a garden party or barbecue, or as a top-up between main feeds

3. Westland SafeLawn

Type: Granular (organic) | Coverage: 80–400m² | Price: Around £10–£28

For households with children, dogs, or cats, Westland SafeLawn is the standout choice. It’s made from 100% natural ingredients with no pesticides or herbicides, so there’s no need to keep anyone off the lawn after application. The organic formula feeds the grass while also improving soil health by encouraging beneficial microorganisms.

It naturally helps to thicken the lawn, which in turn suppresses weeds and moss without any chemicals. The iron content is deliberately kept very low, so there’s no risk of staining paths or patios if granules get tracked around on shoes or paws. The one downside worth mentioning is the smell – it’s essentially composted organic matter, so it has a noticeable farmyard odour for a day or two after application.

Pros: Completely safe for children and pets; improves soil health; no risk of hard surface staining; available at Tesco, Amazon, and garden centres

Cons: Strong manure-like smell when first applied; slower results than chemical feeds; won’t kill existing weeds

Best for: Families with young children or pets who want a natural approach to lawn care

4. A1 Lawn Ultimate Spring Summer Fertiliser

Type: Granular (professional) | Coverage: 70–560m² (depending on bag size) | Price: Around £12–£40

This is where things step up from consumer-grade to professional territory. The A1 Lawn Ultimate has an NPK ratio of 10-4-4 with added iron, magnesium, and seaweed extract. It’s DEFRA-certified and has been tested by FERA and SASA, which gives confidence in its quality and consistency.

The high nitrogen content drives rapid, deep green growth, while the phosphorus and potassium provide balanced root and stress support. The added seaweed is a nice touch – it supplies trace minerals and helps improve soil structure over time. Users consistently report lush, dense growth with fewer weeds, and the mini-granule format makes it easy to apply evenly.

Pros: Professional-quality formula; DEFRA certified; excellent NPK balance for spring and summer; includes seaweed and iron; available in multiple bag sizes

Cons: Slightly more expensive per square metre than budget options; no weed killer included; needs watering in during dry spells

Best for: Lawn enthusiasts who want professional results and don’t mind paying a bit more for quality

5. ICL Sportsmaster Spring Summer 9-7-7

Type: Granular (professional) | Coverage: 357–714m² | Price: Around £35–£50 for 25kg

If you’ve got a large lawn or paddock, buying consumer-sized boxes quickly becomes expensive. ICL Sportsmaster is the fertiliser used on golf courses, football pitches, and sports grounds across the UK, and it’s available to home gardeners in 25kg bags that cover up to 714m².

The 9-7-7 NPK formula is well balanced for the growing season, with enough nitrogen for strong green growth and good levels of phosphorus and potassium for overall lawn health. The mini-granule format breaks down quickly – you’ll see results within a week – and the risk of scorching is low compared to some cheaper alternatives. It also works well as a pre-seeder fertiliser if you’re overseeding bare patches.

Pros: Exceptional value for large areas; professional quality trusted on sports pitches; fast-acting mini-granules; low scorch risk

Cons: 25kg bags are bulky to store and handle; no weed or moss control; you’ll need a spreader for even application over large areas

Best for: Large lawns, paddocks, or anyone who wants professional-grade results at trade prices

6. Elixir Gardens Spring & Summer 9-7-7

Type: Granular | Coverage: 28–700m² (1kg–25kg bags) | Price: Around £6–£30

Elixir Gardens offers a solid 9-7-7 formula similar to the ICL Sportsmaster but in more flexible bag sizes, starting from just 1kg. This makes it a practical choice if you don’t want to commit to a 25kg sack. The granular compound includes added iron and magnesium oxide, which helps improve colour and supports photosynthesis.

Customer reviews praise the quality and value, and Elixir Gardens has a strong reputation on Trustpilot for fast delivery and good service. The granules spread easily by hand or with a conventional spreader, and you’ll see visible improvement within a week or so. It’s not as well known as the big-brand alternatives, but don’t let that put you off – the formula is every bit as capable.

Pros: Flexible bag sizes from 1kg upwards; includes iron and magnesium; good value; well-reviewed brand with strong customer service

Cons: Less widely available in physical shops; no weed or moss control; lesser-known brand may lack the reassurance of household names

Best for: Budget-conscious gardeners who want a professional-style feed without buying a huge bag

7. Vitax Green Up Enhance Liquid Lawn Feed

Type: Liquid (soluble) | Coverage: Up to 200m² | Price: Around £10–£15

Most lawn feeds come as granules, but Vitax Green Up Enhance is a soluble liquid that you mix with water and apply through a watering can or hose-end sprayer. It’s a favourite among professional greenkeepers who want precise, even application with no risk of granule scatter or scorching.

The formula includes seaweed extract and a turf wetting agent, which helps the nutrients penetrate the soil and reduces grass stress during hot, dry spells. It’s particularly useful in summer when the soil can become hydrophobic (water-repellent) and granular feeds struggle to work properly. The results are noticeable within days, and you get the satisfaction of watching the green come back almost in real time.

Pros: Even, precise application; includes seaweed and wetting agent; excellent for drought-stressed lawns; no scorch risk

Cons: More time-consuming to apply than scattering granules; needs mixing; effects are shorter-lived than slow-release granular feeds

Best for: Gardeners who prefer liquid feeding, or anyone dealing with dry, compacted soil in summer

When and How to Apply Lawn Feed

Getting the timing right is just as important as choosing the right product. In the UK, the main feeding season runs from late March through to September, with most lawns benefiting from two or three applications spread across the growing season.

Spring (late March – May): This is the most important feed of the year. Your grass is waking up from winter dormancy and needs a nitrogen-rich boost to kickstart growth. Apply once temperatures are consistently above 10°C and the ground is no longer frozen or waterlogged.

Summer (June – August): A lighter feed helps maintain colour and density through the warmer months. Avoid feeding during prolonged heatwaves or drought – the grass is already under stress and won’t be able to take up the nutrients. Water in well after application if rain isn’t forecast.

Autumn (September – November): Switch to an autumn/winter feed that’s lower in nitrogen and higher in potassium to toughen the grass up for winter. This is outside the scope of this guide, but worth noting so you don’t apply a spring feed too late in the year.

For application, always follow the manufacturer’s recommended rate – more is not better with lawn feed, and over-application can scorch the grass. A wheeled spreader gives the most even coverage on larger lawns, but hand spreading works fine for smaller areas. Try to apply on a calm, overcast day when rain is expected, as this helps the granules dissolve and reach the roots without needing manual watering.

Granular vs Liquid Lawn Feed: Which Should You Choose?

This is one of the most common questions we get, and the answer depends on your priorities.

Granular feeds are the most popular choice for UK gardeners, and for good reason. They’re easy to store, simple to apply, and many formulas are slow-release, meaning they feed the lawn steadily over several weeks. They’re generally better value per square metre and require less frequent application.

Liquid feeds are absorbed faster and give quicker visible results. They’re excellent for lawns under stress or for a rapid green-up, and they allow more precise, even application. The trade-off is that the effects wear off sooner, so you may need to reapply more frequently.

Our recommendation for most UK gardeners is to use a granular feed as your main treatment in spring and late summer, and keep a liquid feed on hand for quick top-ups or to help the lawn recover during dry spells.

Common Lawn Feeding Mistakes to Avoid

Over-feeding: Applying too much fertiliser is one of the quickest ways to damage your lawn. It can scorch the grass, cause excessive soft growth that’s prone to disease, and harm the soil biology. Always measure your lawn area and follow the stated application rate.

Feeding in drought: If there’s been no rain for weeks and you can’t water the lawn, hold off on feeding. Fertiliser sitting on dry soil won’t dissolve properly and can burn the grass.

Using weed killer when you don’t need it: If your lawn doesn’t have a significant weed problem, a straight fertiliser without herbicide is better value and less stressful for the grass. Weed-and-feed products also prevent you from overseeding for several weeks afterwards.

Feeding too late in the year: A high-nitrogen spring feed applied in October will push soft, sappy growth that’s vulnerable to frost and disease. Switch to a dedicated autumn feed from September onwards.

Our Verdict

For most UK gardeners, the Miracle-Gro EverGreen Complete 4-in-1 is the best starting point. It tackles the most common lawn problems in a single application and is available everywhere from Amazon to your local garden centre. If your lawn is in decent shape and you just want to keep it fed, the A1 Lawn Ultimate Spring Summer offers the best balance of professional quality and value.

Families with pets and young children should go straight for the Westland SafeLawn – the peace of mind alone is worth it. And if you’ve got a large lawn or want to save money long-term, the ICL Sportsmaster in a 25kg bag is hard to beat on a per-square-metre basis.

Whichever product you choose, the single most important thing is to actually feed your lawn regularly. A well-fed lawn is naturally thicker, greener, and more resistant to weeds, moss, and drought. Start this spring, stay consistent, and you’ll see the difference within weeks.
