⭐ Reviews – Best Lawn Feed UK of 2024
Our top recommended choice for anyone looking for the very best-value lawn feed today is the Miracle-Gro Water Soluble Lawn Food.
This lawn feed is one of the most popular and highly-rated UK lawn feeds on Amazon, with more than 5,000 reviews and a 4.5-star rating out of 5. Why is it a customer favourite? Because it’s reliable and works exactly as advertised, helping grass grow greener, thicker, and stronger. Plus, it’s fantastic value, at just under £10 for a 1-kilogram box.
Quick Specs:
Brand: Miracle-Gro
Price: £
Size: 1 kilogram
Treatment Area: 100 m² per 500g sachet
Season: Spring, summer, autumn
Ingredients: Nitrogen, phosphorous pentoxide, potassium oxide, iron
Application Frequency: Every 4-8 weeks
Results in: 5-14 days
Best For:
Anyone looking for the best-value lawn feed that’s suitable for use throughout most of the year and reliably produces the best results on UK lawns.
What Customers Think:
The Miracle-Gro Water Soluble Lawn Food is one of the best-reviewed grass feed products we’ve seen, with customers calling it a “literal miracle” and “superb”. Reviewers agreed that this lawn fertiliser is easy to use and encourages greener, thicker grass growth within as little as 1-2 weeks. The before-and-after photos are a good way to see the results that customers have reported.
Pros:
It’s rare to find a lawn feed that has worked so consistently and reliably for the majority of customers. It’s suitable for use from March to October (you only need to apply it once a month, maximum), so you can keep your lawn in tip-top condition from spring to autumn.
The fertiliser is a winning blend of nitrogen, which promotes grass greenness, phosphate, which encourages strong root growth, potash, which improves disease and drought resistance, and iron, which stimulates chlorophyll production.
It’s quick and easy to apply this product with your watering can, and there are several small pouches in the box – a great idea as it stops the product from going off if you use it in batches. If you want to get the job done in even less time, we recommend buying the Miracle-Gro Hose Feeder (sold separately).
The manufacturer says you’ll see results in as little as 5 days, but most people saw noticeable changes (i.e. good enough for a before-and-after photo) within 7-14 days. That’s still an impressive timeframe, and ideal if you want to make your lawn presentable in time for a family event or you just want proof that you’ve spent your money wisely.
Cons:
Nothing to report so far!
If you’re looking for a fertiliser and moss/weed killer, we think the Miracle-Gro Evergreen Complete 4 in 1 Lawn Food can’t be beaten.
This efficient lawn feed has four primary functions; it thickens grass, encourages grass greenness in less than 7 days, eradicates weeds, and kills moss. It’s another hugely popular product on Amazon, with more than 17,000 reviews and counting.
Quick Specs:
Brand: Miracle-Gro
Price: ££
Size: 12.6 kilograms
Treatment Area: 360 m²
Season: Spring, summer
Ingredients: Nitrogen, potassium
Application Frequency: Every 12 weeks
Results in: 7 days
Best For:
Anyone who wants to achieve a green, weed-free lawn with an all-in-one product, rather than having to buy lawn food and weed killing solutions separately.
What Customers Think:
Customers agree that the Miracle-Gro Evergreen Complete 4 in 1 Lawn Food is the best lawn feed for anyone looking for a feed and weed treatment in one. This popular lawn feed has a 4.4-star rating from more than 17,000 reviews, with customers commenting that it’s an “all round good and effective lawn treatment” and “great value for money”.
Pros:
We think the Miracle-Gro Evergreen Complete 4 in 1 Lawn Food is the best value for money who anyone who wants to tackle moss and weeds as well as support fast, green grass growth. The fertiliser has a unique ‘WaterSmart’ formula, which encourages water and nutrients to absorb into the grass, protecting it from stress-related conditions and drought.
The formula has an NK ratio of 14-5 – so plenty of nitrogen for speedy grass growth, a decent amount of potassium for root development, and no phosphorous (which is best in autumn/winter lawn feeds).
Unlike other lawn feeds, you don’t only have one or two bag sizes to choose from. We’ve reviewed the 12.6-kilogram bag for a 360 m² area, but you can buy the feed in other sizes for use on 80-500 m² lawns. That means you can tailor your purchase to your exact lawn size, so you won’t end up wasting the last quarter or third of the pack, or having to buy two bags because one bag doesn’t quite cover it all.
It’s easy to apply this Miracle-Gro lawn food. It’s a granule formula, so you don’t need to mix or dilute it first. Just add the feed to your lawn spreader or buy the product in a spreader bottle, which helps distribute the fertiliser more evenly.
Cons:
As with all moss killers, you may end up with a few patches of bare ground after raking away the dead moss, but your grass should soon grow to cover these areas.
We think the Richard Jackson Flower Power Premium Lawn Magic ticks all the boxes for anyone looking for a versatile lawn feed that can be used year-round to achieve a greener, thicker lawn.
This professional-inspired formula can be used every 4-6 weeks throughout the year (as long as the ground temperature is above 5°C), keeping your lawn well supplied with the nutrients it needs for healthy growth no matter the season.
Quick Specs:
Brand: Richard Jackson
Price: ££
Size: 5 litres
Treatment Area: 500 m²
Season: Spring, Summer, Autumn
Ingredients: Nitrogen, calcium oxide, magnesium oxide, iron, seaweed extract, natural sugars
Application Frequency: Every 4-6 weeks
Results in: 5-7 days
Best For:
Anyone who prefers the value for money of buying a single very effective lawn feed for year-round use, rather than spending money on multiple specific fertiliser products for specific seasons.
What Customers Think:
The Richard Jackson Flower Power Premium Lawn Magic is favoured by more than 1,000 customers on Amazon, with an average star rating of 4.4 stars out of 5. Customers called this liquid lawn feed “a miracle product” and “the defibrillator for my lawn”. There are a few customer before-and-after photos that speak for themselves.
Pros:
We think the obvious advantage of this Richard Jackson liquid lawn feed is that it can be used in all seasons, so you don’t have to go out of your way to buy seasonal lawn feed with special ingredients. The container has a screw-top lid, like a milk carton lid, so you get a better seal than you would with a plastic packet, for fresher storage between uses.
The Premium Lawn Magic feed contains nitrogen, calcium oxide, magnesium oxide, and iron, creating a double-action formula that does two jobs in one: strengthens grass roots and improves grass greenness. It also contains a couple of more unique ingredients: natural sugars, which build disease resistance, and added seaweed extract, which has bio-stimulant benefits.
This lawn feed formula is safe for children, pets, and other animals, so you can use it year-round without having to worry about the safety of your family members (just keep children and pets off the lawn for around 2-3 hours post-application while it absorbs into the soil).
It’s also super easy to use – it can be mixed with water (100ml to 5 litres of water) and watered straight onto your lawn with a watering can.
Cons:
Nothing to mention so far!
If you’re keen to achieve a lush green lawn in time for the “outdoorsy” season in the UK, we think you can’t go wrong with the A1 Lawn Ultimate Spring Summer Lawn Fertiliser.
This big 10-kilogram bag of fertiliser granules will keep you going year after year, so if you like to spend a little more upfront for better long-term value, here’s your solution. The A1 Fertiliser is ideal for spring and summer because it’s rich in nutrients and helps replenish nitrogen in the soil, which is used rapidly during this increased phase of grass growth.
Quick Specs:
Brand: A1 Lawn
Price: ££
Size: 10 kilograms
Treatment Area: 280 m²
Season: Spring, summer
Ingredients: Nitrogen, phosphorous, potassium, magnesium oxide, iron, calcium oxide, seaweed
Application Frequency: Every 8 weeks
Results in: 5-7 days
Best For:
Folks looking to spruce up their lawn in the spring and summer months and supply the essential nutrients needed to support rapid, healthy grass growth for a greener lawn in 5-7 days.
What Customers Think:
More than 600 customers have reviewed the A1 Lawn Ultimate Spring Summer Lawn Fertiliser, awarding it an average rating of 4.6 stars out of 5. Reviewers agreed that the product is a “brilliant lawn fertiliser” and “really works”. One customer called it “steroids for grass” and said it turned their lawn “greener than Wembley grass”. Several reviewers advised on using a spreader rather than hand-spreading for the best results.
Pros:
We think the A1 Lawn Ultimate Spring Summer Lawn Fertiliser has the best composition for using during the rapid grass growth phase in spring and summer. It’s rich in nitrogen, potassium, and phosphorous, which are essential for grass after a harsh winter because they help establish root growth and plant development. That means you can enjoy a green, healthy lawn that’s strong enough to fight off disease, drought, and stress.
These nutrients also help grass to survive extreme weather conditions, like dry, blazing hot summers (i.e. our two-week summer heatwave in the UK).
Having a granular feed means you can spend less on the product upfront and it’s easier to store, so you can keep it in your shed and use it as and when needed.
Cons:
The smallest bag is 10 kilograms, so there’s no option to try a smaller bag and sample the fertiliser before committing to a supply that’ll last you a long time
For folks who want to sustain a healthy lawn throughout the bitter winter months, we recommend the Miracle-Gro EverGreen Autumn Lawn Care Fertiliser.
This autumn fertiliser contains seaweed, which helps grass to grow a strong root system and stand up against the cold weather. It also contains iron, which controls and kills moss – a particularly common lawn problem in autumn due to the colder, wetter weather conditions.
Quick Specs:
Brand: Miracle-Gro
Price: ££
Size: 14 kilograms
Treatment Area: 400 m²
Season: Autumn
Ingredients: Nitrogen, phosphorous pentoxide, soluble in neutral ammonium citrate, potassium oxide, iron sulphate
Application Frequency: Every few weeks (no specific recommendation)
Results in: 7 days
Best For:
People who are specifically looking for the best-value granular autumn lawn feed/moss killer that’s formulated to prepare grass for the winter months.
What Customers Think:
Over 1,000 customers have rated the Miracle-Gro EverGreen Autumn Lawn Care Fertiliser 4.4 stars out of 5, so it’s another popular lawn feed on Amazon. Reviewers called it a “good autumnal weed and feed” and a “very effective fertiliser”, with one reviewer saying that it had more of a greening effect and prompted faster grass growth than any liquid fertiliser they’d used.
Pros:
The Miracle-Gro EverGreen Autumn Lawn Care Fertiliser is specially formulated for treating common autumn lawn issues and preparing grass for the colder winter months. It’s lower in nitrate than spring-summer feeds because you want to reduce leaf growth as winter approaches, but its seaweed content encourages healthy root development and its iron content kills moss, which is usually at its worst in October-November.
This is another super-simple lawn care product. Just apply to your lawn using a spreader, water thoroughly the next day, and mow your lawn three days after treatment. If you’ve used it to kill moss, simply wait two weeks, then rake the dead moss off your lawn.
One 14 kilogram bag covers up to 400 square metres of space, so it’s one of the best lawn feeds we’ve reviewed in terms of value for money. The coverage is suitable for treating an entire medium-sized lawn.
Cons:
Some customers said the feed didn’t do a great job of getting rid of their lawn’s moss.
If you’re after a two-in-one autumn lawn fertiliser that you can transition into winter use, we think the Proctors Autumn And Winter Grass Feed is the best on the market for this purpose.
This lawn feed is designed to protect your lawn during the winter season, so you can enjoy healthier, greener grass by the time spring comes around. It’s sold in 20-kilogram bags for a 571 m² space, and contains a blend of nutrients to support healthy root growth while discouraging top growth (which is unnecessary during autumn and winter).
Quick Specs:
Brand: Proctors
Price: ££
Size: 20 kilograms
Treatment Area: 571 m²
Season: Autumn/winter
Ingredients: Nitrogen, phosphorous, potassium
Application Frequency: Every 6-8 weeks
Results in: 7-14 days
Best For:
Folks who want the best lawn feed to use throughout autumn and winter to protect their lawn over the cold seasons and prepare it for spring and summer.
What Customers Think:
More than 150 customers have rated the Proctors Autumn And Winter Grass Feed 4.6 stars on Amazon, agreeing that it’s a “great product” and produces a “thicker, greener lawn without the need for extra cutting”. A few customers said that they didn’t notice any difference after using this feed – keep in mind that the purpose of a winter lawn feed is to support root development, not increase grass growth.
Pros:
The Proctors Autumn And Winter Grass Feed is ideally formulated for protecting lawns over winter and reducing lawn issues associated with cold, damp weather. It has a low nitrogen content, reducing top growth and preventing you from having to mow frequently in the milder autumn months, and contains phosphorous for healthy root development and potassium for disease protection.
We think the micro-granule formula of this lawn feed is the perfect middle-ground between liquid fertilisers, which are absorbed quickly and aren’t ideal for protecting a lawn over the long winter months, and large granules, which can take months to dissolve. Proctors’ micro-granules offer gradual protection over six weeks from the time of application, making them ideal for an autumn/winter grass feed.
While this Proctors feed won’t make your lawn any greener over winter (that’s not the point of any winter lawn feed), it’ll help your grass to grow healthy roots, extending its life, increasing efficiency of nutrient uptake, and reducing your future fertiliser use.
Cons:
It’s a little expensive for a 20-kilogram bag.
Based on our research, we think the envii Greenkeeper’s Secret Liquid Lawn Fertiliser Feed is the best liquid lawn feed to go for if you want a fast-acting fertiliser that will give you results within a matter of days.
As a liquid fertiliser, this envii product is quickly absorbed into soils, where the nutrients can then be absorbed by your grass, helping you to achieve a lush green lawn faster. Plus, it’s quick and easy to apply, with a simple bottle design that attaches to your garden hose and sprays the formula straight onto your grass.
Quick Specs:
Brand: envii
Price: £
Size: 1 litre
Treatment Area: 300 m²
Season: Spring, summer
Ingredients: Nitrogen, phosphorous, potassium
Application Frequency: Every 6 weeks
Results in: 7-10 days
Best For:
Anyone who wants to see fast, noticeable results from their investment in one of the best liquid lawn feed products.
What Customers Think:
The envii Greenkeeper’s Secret is rated 4.1 stars on average out of 1,500+ ratings, with reviewers commenting that it’s a “great product” that “greens the grass”. A couple of customers had issues with defective spray applicators, but it seems these are old models that have since been updated by the manufacturer.
Pros:
The envii Greenkeeper’s Secret Liquid Lawn Fertiliser Feed is specially formulated for fast results. It uses a liquid formula that provides nutrients to the soil instantly, so you’ll see a difference faster than with granular lawn feed products. Most people saw a noticeable difference after 6-10 days of application.
There’s no messing about with the application process, either – the bottle is a spray applicator that attaches to your garden hose, so you can spray it straight onto your lawn without having to get your measurements right or ending up with unevenly scattered granules across your lawn.
This liquid fertiliser formula contains all the good stuff, including nitrogen, which promotes chlorophyll production (essential for faster-growing, greener grass), phosphorous, which improves root growth (so your grass should be more resistant to the changing seasons), and potassium, which supports general grass health and tolerance to drought and cold.
Cons:
The bottle design means there’s always a bit left that the spray applicator won’t be able to draw. If you want to use this last bit, you’ll have to dilute it in a watering can with some water.
If you want to spend less than £10 on an effective lawn feed product without compromising on quality or safety, the Plantworks Ltd Empathy Lawn Feed Liquid Seaweed Stimulant is our top recommendation for you.
A little goes a long way with this lawn feed liquid concentrate – you just need two capfuls diluted in water to support a greener, thicker lawn. Plus, it’s the only product on this list that’s a seaweed-based feed and biostimulant (others just contain seaweed as an ingredient), so it’s all-natural and kind to the environment.
Quick Specs:
Brand: Plantworks
Price: £
Size: 1 litre
Treatment Area: Not specified
Season: Spring, summer
Ingredients: Liquid seaweed concentrate
Application Frequency: Twice a week
Results in: 5-7 days
Best For:
Anyone with a smaller budget who prefers to spend less upfront on a lawn feed that’s as effective as products twice its price.
What Customers Think:
More than 1,000 customers have rated the Plantworks Ltd Empathy Lawn Feed Liquid Seaweed Stimulant 4.3 stars out of 5, commenting that it’s “great value”, and “good all round product”, and makes lawns a “lush green”. Some customers had issues dosing out the product for use on their lawn.
Pros:
We think the best feature of the Plantworks Ltd Empathy Lawn Feed Liquid Seaweed Stimulant is its price. You get 1 litre of concentrated liquid lawn feed for less than £10, and you only need to use two capfuls per application, so you get fantastic long-term value from your initial purchase.
It’s great to see that you have two application methods to choose from with this lawn feed – you can either use it bi-weekly to sustain a green, healthy lawn from March through October, or you can apply three times the amount (6 capfuls rather than 2) for a “rapid green up” whenever needed.
We also love that this Plantworks product is an organic lawn feed made from seaweed concentrate. Seaweed contains natural growth chemicals, like auxins and cytokinins, which support grass development. Plus, it’s all-natural and sustainably harvested, so it’s pet-friendly and completely safe to use on your lawn, and a guilt-free purchase if you care about protecting the environment.
Cons:
You have to measure out the product using the provided cap for proper dilution, which isn’t as efficient as some of the spray-design liquid lawn feed products.
While this product is pretty quick to produce results, they don’t last long. You’ll need to re-apply the feed bi-weekly if you want to enjoy a lush green “just fertilised” lawn in the long run.
Based on our research, the Westland 20400352 SafeLawn Child and Pet Friendly Natural Lawn Feed is the best lawn feed for anyone specifically looking for children- and pet-safe fertiliser.
This natural lawn feed is made from organic matter, which is safe and non-toxic to pets and children, so you don’t have to keep your family off your lawn after applying the formula. Plus, it also contains grass seed, so it doesn’t only improve the greenness and thickness of your existing lawn – it also encourages new grass growth.
Quick Specs:
Brand: Westland
Price: £
Size: 2.8 kilograms
Treatment Area: 80 m²
Season: Spring, summer
Ingredients: Organic matter, grass seed
Application Frequency: No specific recommendation
Results in: 7 days
Best For:
People looking for a grass seed and feed product that thickens lawns and encourages new grass growth without posing a risk to pets and children.
What Customers Think:
More than 5,000 customers have reviewed this Westland lawn feed on Amazon, giving it an average star rating of 4.3 out of 5. Reviewers commented that the lawn feed “works amazingly” and produces “thicker, greener grass”, but some customers said they didn’t receive any grass seed in their box.
Pros:
If you’re not a fan of putting harsh chemicals on your lawn, the Westland 20400352 SafeLawn Child and Pet Friendly Natural Lawn Feed should tick your boxes. It’s chemical-free and made from natural organic matter, so there’s no risk to your kids and pets, and it’s better for the environment.
We like the uniqueness of a fertiliser that’s also a grass seed, so you can fill in bare patches rather than simply covering them up with thicker grass from the surrounding areas.
Price is another plus point. You’ll probably only need to use this treatment for a one-off application since it also contains grass seed, and it costs less than £10 to treat an 80 m² area. You can double or triple the box size for lawns up to 400 m², at a much better value than buying two or three lots of the smallest box.
Cons:
The feed’s organic matter content means it’s a little smelly when you open the packet.
Your pets might be attracted to the fertiliser’s smell and protein content. While the feed isn’t toxic or dangerous, you obviously don’t want your pets eating it! If this happens, the manufacturer recommends watering-in the product after you’ve applied it to encourage it to absorb more quickly into your lawn.
🌱 Why Do You Need A Lawn Feed?
You might be wondering just how essential a lawn feed actually is. After all, grass should get plenty of nutrients naturally from the soil, right?
This is correct – but it doesn’t mean that your grass won’t benefit from an extra boost of nutrients from an external source.
To understand the benefits of lawn feed, let’s compare it to the humble protein shake.
Many athletes, especially those with an interest in weight training, use protein shakes as a quick and easy way to get a protein kick.
That’s not to say that their diets are necessarily lacking in protein, but protein shakes provide a bit of extra nutritional value to help boost their performance and achieve their muscle-building goals faster.
Grass fertiliser works in a similar way on your lawn.
It’s true that most of the nutrients in grass feed are present naturally in soils. But grass feed can provide additional nutrients to help your grass grow greener, thicker, and stronger.
Whether you have a sad-looking lawn with bare patches, or you just want to bring colour and life to a dull grassy space, lawn feed is your best friend.
📝 4 Features To Look For In The Best Lawn Feed In The UK
Here are the four features to look for in the best lawn feed for a lush green lawn in the UK.
💰 Value For Money
As you’ll have noticed from the reviews above, different lawn feeds are sold in different quantities.
That makes it difficult to know whether you’re getting the best value for money, since there’s no set price point because there’s no set feed quantity.
Consider the following things to find out the value for money of a lawn feed:
The product coverage area
The scope and frequency of application
The product effectiveness
The product price
You can find out the feed coverage area, the product price, and the scope and frequency of application, from the product description.
Read customer reviews to learn about the fertiliser’s effectiveness. Look at before-and-after photos and make a mental note of how many customers were pleased with the results of the feed.
Essentially, the larger the feed’s coverage area and the less frequently it needs applying, while still showcasing effective, long-lasting results, the better its value for money.
But that’s not to say you should buy the biggest lawn feed even if it does work out at the best value. If you only have a small lawn and plan to use a lawn feed just once to give it a boost, you may as well save your money and buy a less expensive product.
We’ve discussed how to budget for the best lawn feed products below.
🐶 Pet and Child-Safe
If you have children and pets who spend a lot of time in your garden, you need a lawn feed that’s safe for them.
A lawn feed that’s advertised as “children and pet-friendly” or “children and pet-safe” means it doesn’t contain harsh chemicals and won’t cause irritation if it comes into contact with your loved ones’ feet (or paws!).
We recommend looking for an organic fertiliser if your priority is enhancing your lawn at no risk to your family members.
Water-soluble lawn feed is also a good shout for families with children and pets because it’s absorbed quickly by soils, so you’ll only have to keep your home’s occupants off your lawn for a few hours.
🧬 Slow-Release Formula
When it comes to speed of nutrient absorption, there are two different fertiliser types to choose from today: slow-release and quick-release.
We’ve compared these later in the “considerations” section of this guide, but our recommendation is to go for a slow-release fertiliser.
Why? Because slow-release formulas are a better value for money. Rather than providing a quick source of nutrients that gives your lawn an initial boost but are quickly used up, a slow-release fertiliser gradually releases nutrients over time, so your lawn looks greener and healthier for more than just a few days.
Slow-release lawn food also has a reduced likelihood of burning the grass because of its gradual release of nutrients. Still, make sure to follow the dosage instructions carefully.
📈 Good Nutrient Content
The nutritional content of a lawn feed should be optimal for your intended purpose.
The best lawn feed products usually contain a combination of nitrogen, phosphorous, and potassium. These combine to encourage lush green growth, support root development, enhance overall plant health, and reduce the likelihood of diseases.
Seaweed is a popular ingredient in organic lawn feed, and has a similar effect on lawns. It’s rich in natural growth-promoting hormones like auxins, cytokinins, and gibberellin, which encourage grass leaf and root development.
Some natural lawn feeds are made from organic matter, which supports healthy soils and improved grass quality.
You’ll notice that we haven’t mentioned any particular ingredients you should definitely look for in the best lawn feed, or the ratios of these ingredients. That’s because the unique ingredients that are best for you in a lawn feed depend on your situation, including your desired outcomes and the time of the year that you’re applying the feed.
We’ve discussed this more in the below section.
🛡 Good Brand Reputation
Finally, we recommend looking for lawn feed brands with a good reputation and positive customer reviews.
The products featured in our lawn feed reviews section all have hundreds (many have thousands) of reviews from customers, with an average overall star rating of at least 4.2 stars out of 5.
We know that buying from a trusted brand gives you a much more guaranteed value for money than chancing it on a new product from a relatively unknown brand. With a trusted brand, you have the reassurance of knowing you’re using a tried-and-tested formula that has been used and loved by thousands of customers just like yourself. Plus, reputable brands often price their products the most competitively, so you don’t have to spend a fortune just for the brand name.
Customer reviews will tell you everything you need to know about a product’s performance. Many of the best lawn feeds have been reviewed by customers who’ve shared before-and-after photos of their lawns, which is a good way to get a visual interpretation of what your lawn could look like after using the product.
🧾 11 Considerations When Buying Lawn Feed
As well as looking for the best features of lawn feed, also consider the following factors when you’re buying lawn feed in the UK.
💰 Your Budget
Start by determining your budget.
Lawn feed products cost £8-£35 on average, depending on the amount of feed in the package and the size of the area it’ll cover.
You can typically get the best value for money if you buy a larger package that you can use several times a year, or for several years in a row (depending on your frequency of application). However, this means spending more money upfront, which you might not want to do.
If you only have a small lawn and you want to give your lawn a one-off boost, you can spend less than £10-£15 upfront on quality lawn food (depending on your lawn size).
If you want to achieve the perfect lawn year-round with regular lawn feeding, the average annual cost of lawn feed is £75-£150.
🍂 Seasonal Differences
Not all lawn feed works effectively in all seasons.
In spring, look for a fertiliser with a high amount of nutrients, particularly nitrogen, because a lot of nitrogen is used rapidly for grass growth, reducing the natural amounts present in the soil.
Summer is the only season when fertilisers aren’t usually necessary. Your lawn should be getting plenty of sunlight, which encourages rapid enough growth without the extra fertiliser boost. The most important thing is to water your lawn during any dry spells to prevent it from drying out.
If you do choose to use lawn food in the summer, go for a slow-release granular lawn feed that will gradually release nutrients into your soil, preventing any crazy growth spurts that will see you mowing multiple times a week.
Autumn and winter feeds should be lower in nitrogen and higher in iron sulphate, which provides more focused root development and helps keep weeds and moss at bay during the damp, cool seasons.
Is it a major problem if you use the wrong lawn feed for the season? No – and, in fact, some lawn feeds are marketed as all-season feeds – but you might notice a few undesirable results.
For instance, if you use a spring lawn feed in autumn, the high nitrate content will promote grass leaf growth – something you don’t need as you’re going into winter.
Essentially, choosing the right lawn food for the season will help you to get the best value from your purchase, giving you the best results for the time of the year.
⚗️ Nitrogen: Phosphorous: Potassium (NPK) Ratio
Don’t just choose the best lawn feed based on the manufacturer’s performance claims.
If you want to be certain that a fertiliser is worth the investment based on your situation, check the ratio of nitrogen, phosphorus, and potassium (NPK) in the product.
The best lawn feed ratio for you depends on your garden’s needs:
If you want to establish strong roots (which, in turn, promotes healthy leaf growth and helps your grass to survive very cold and hot weather conditions), phosphorous is a key ingredient to look for.
If you want to encourage leafy growth and achieve a greener lawn, look for lawn feeds with nitrogen as the main ingredient.
Potassium is often included alongside nitrogen and phosphorous to support overall grass health, root growth, and plant development.
We recommend choosing a lawn feed that’s high in phosphorus and nitrogen if you’ve just seeded a new lawn. If you have an established lawn that’s looking dull or lackluster, stick with a high-nitrogen lawn feed, which will help you to achieve a faster-growing, more vibrant lawn.
How do you know a product’s nitrogen: phosphorous: potassium ratio? This information should be available in the product description or on the back of the package. You can also get an understanding of the ratios of the ingredients by checking the ingredients list. The ingredient that’s present in the largest quantity should be listed first. Contact the manufacturer if you’re unsure.
🧪 Organic Vs Synthetic Feed
Also decide whether you prefer to use organic or synthetic feed on your lawn.
Organic lawn feeds are derived from natural sources, like seaweed or plant and animal waste. They often combine nutrients with organic compounds and beneficial microorganisms, which support healthy soils and encourage plant growth. Organic lawn food is typically made from organic seaweed extract or organic matter.
Synthetic lawn feed is made from synthetic ingredients and formulated with specific nutrient ratios. Synthetic feeds usually contain a higher concentration of nutrients, especially nitrogen, which encourage grass to grow rapidly and improve leaf greenness.
Whether you choose organic or synthetic lawn feed depends on your personal preferences and gardening goals:
If you’re looking for a sustainable, environmentally-friendly lawn feed, go for an organic fertiliser, which is made from natural, renewable resources and won’t negatively impact soil biology over time if overused.
If you want the best and most visible results, with fewer applications required per year, look for a synthetic fertiliser, which contains a concentrated formula of all the nutrients your grass needs to grow quickly.
Ultimately, the best choice for you depends on your specific lawn needs, as well as your gardening philosophy and environmental concerns.
Some gardeners prefer a combination of both lawn feeds, using organic feeds to support long-term soil health and supplementing with synthetic feeds for quick greening when necessary.
Whichever option you choose, always follow the application instructions carefully to avoid overfeeding and potential damage to the lawn.
🏁 Slow-Release Vs Quick-Release
We’ve recommended looking for a slow-release fertiliser already, but you might prefer the features of a quick-release lawn feed. Consider the pros and cons of both when deciding on the best lawn feed for your needs.
Slow-release fertilisers gradually release nutrients over an extended period, so they’re better for folks who want to maintain a high-quality lawn throughout the year.
Quick-release feeds produce instant results that aren’t as long-lasting, so they’re better for one-off applications or anyone who’s happy to commit to more frequent lawn maintenance.
You can often get the best value from a slow-release lawn feed, but you might still prefer quick-release lawn feeds that give faster results. It just depends on your intended goals.
📆 Application Rate And Frequency
The application rate of fertiliser refers to how much feed is needed per square metre of your lawn, and it’s worth considering if you want to get the best value from your purchase.
Most lawn feeds require a very light application. A little goes a long way – and, in fact, applying too much fertiliser could scorch your lawn.
Make sure to follow the manufacturer’s instructions carefully and don’t be tempted to apply more feed than recommended to produce better results, since this could have the opposite outcome and lead to damage that you’ll then have to put more money into fixing.
Some lawn feeds require more frequent application than others. Generally, synthetic feeds should be applied once every 6-8 weeks. Organic feeds usually require more regular applications – as often as once or twice a week.
🔍 Soil pH
If you’ve already spent some time reading lawn feed reviews from other customers, you might have noticed that even the best lawn feed products have a small percentage of reviews that say something along the lines of “this didn’t work for me, waste of money,” et cetera.
There are a few reasons why a lawn feed product might not work for you, including incorrect application, poor product quality, and insufficient soil pH.
Making sure your soil’s pH levels are optimal is essential because this makes the fertiliser available to the plant. A pH of 6-7 is the slightly acidic range that grass prefers. Incorrect soil pH may affect the availability of nutrients that the grass plants can absorb, so even if you apply feed, it might not make much difference.
So, make sure your soil pH is optimal if you want to see the clearest results from your lawn feed.
The easiest way to test your soil pH is with a soil pH test kit, which will give you an indication of your soil’s pH in 0.5 increments. If you discover that you need to raise the pH of your soil, we recommend spreading crushed agricultural limestone over your lawn.
🚿 Granular Vs Liquid Fertiliser
Another big consideration to make is whether you prefer granular or liquid lawn feed.
Granular lawn fertilisers, or dry fertilisers, are applied to grass and watered in within 24 hours (if it hasn’t rained after the application).
Liquid lawn feed, or water-soluble lawn feed, is a liquid water-based solution that contains dissolved fertiliser granules. It’s diluted with water (either via a watering can or a hose) and sprayed or poured onto a lawn, where it’s absorbed into the soil and quickly taken in by the grass roots (usually within 2-4 hours).
Both granular and liquid/water soluble fertilisers work effectively to achieve a greener, healthier lawn, and they have similar price points, so the type of feed you choose depends on your situation and preferences.
Granular fertilisers break down gradually in the soil and are released more slowly. They don’t need frequent application, so they’re best for folks looking for a regular lawn feed that they can use throughout the year to provide sustained feeding.
Liquid feed has faster results and is better if your grass needs an instant boost, but you don’t plan to apply lawn feed throughout the year.
🛺 Spreading Applicator
You also need to think about how you’ll spread your lawn feed on your lawn.
If you’re buying granular feed, we recommend spending extra on a fertiliser spreader, like this Gardena Hand-Held Spreader, which will properly distribute the lawn food over the required surface area.
Don’t spread granular feed by hand – you might think that you’ve done an even job, but you’re bound to miss spots and over-apply lawn feed in certain areas, increasing the risk of lawn scorching.
If you don’t want to spend extra on a lawn spreader (such as if you only plan to use lawn food on a one-off basis), avoid granular lawn feed and go for a liquid feed.
Liquid lawn feed can be applied with a watering can with a sprinkler bar application. Some manufacturers sell soluble lawn feeds in applicators that you attach to the end of your garden hose, so you can spray it straight onto your lawn without having to measure out the quantities first.
🌱 Lawn Feed Vs Grass Seed
Lawn feeding and overseeding with grass seed produce similar results, but depending on your situation, you might benefit from one more than the other – or both.
You should use lawn feed to:
Give a browning, pale, or slow-growing lawn a quick nutrient boost.
Maintain lawn health and appearance by providing a steady source of nutrients over time.
Supporting grass root and leaf development throughout the year.
You should use grass seed to:
Fill in patchy or thin areas to promote a denser lawn.
Renovate a lawn that’s in poor condition, with patches disease damage, or weeds.
Establishing a newly laid lawn or starting from scratch.
Lawn feed and grass seed complement one another when used together, helping you to achieve a thicker, greener, denser lawn with good uniformity.
If you have bare patches and your lawn is looking a bit sad and dull, using the best lawn feed in combination with the best grass seed will give you the most comprehensive results.
🍀 The Presence Of Moss/Weeds
On its own, a fertiliser boosts the soil’s nutritional profile and encourages thick, healthy grass growth, which should choke out weeds naturally.
However, if you have a bigger issue with weeds and moss on your lawn, a good lawn feed/weed killer is your best solution for eliminating pesky weeds while also enhancing your grass health.
These lawn weed and feed products usually contain iron sulphate, which attacks and kills moss. You can then scarify or rake your lawn around two weeks after applying the lawn feed, and the dead moss should come away easily.
Some of the best-designed lawn feeds are more than just a moss killer – they also harden the turf to reduce the likelihood of lawn diseases like powdery mildew and brown patch. This further supports your lawn health and maintains its green, uniform appearance, and should also reduce worm casts.
You don’t need to spend extra money on a lawn feed that can control moss and weeds if this isn’t a problem on your lawn. But we do recommend a weed and moss killer if you’ve noticed that weeds and moss are present – especially if you’re treating your lawn in the autumn/winter season, when wet, cold weather conditions make moss a more likely problem.
Just make sure to follow the manufacturer’s application instructions carefully, since over-use of lawn feed weed killers may lead to lawn scorching.
