Best lawn fertiliser UK: picks by job, season and lawn size
Updated: October 2026
The best lawn fertiliser UK choice depends on the job, the month and the area, not on the largest bag or the highest star score. All nine listings are in our [Wolf Garden lawn fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/wolf-garden-lawn-fertiliser). On those scores the top pick is Miracle-Gro 4-in-1 autumn lawn care, 360 m², and the best value is Miracle-Gro autumn lawn care, 360 m². The sections below still attach a pick to a job and a month. This is a listing comparison, not a laboratory test. A qualifying purchase can earn us a commission at no extra cost to you.

Established, weedy lawn from April to September
Miracle-Gro Complete 4 in 1, 360 m², is the pick for an established lawn with weeds and moss from April to September. It was about £24.94, with 4.5 from 309 ratings. The label maximum is 35 g/m², so the stated coverage holds only if you measure the lawn and the dose.
Skip it on a lawn under six months old, if you do not want a herbicide, or if you cannot follow the access rules. The Health and Safety Executive says home gardeners should follow the pesticide label, and extra product can damage grass. A 90 m² weedy lawn in May is a fair use. A new 40 m² lawn is not. Trade-offs are on the weed and moss guide.
Best value per stated square metre
The best value is Miracle-Gro autumn lawn care, 360 m², at about £24.00. The other large Miracle-Gro bags and Westland SafeLawn sit near £0.07 per stated square metre. That is coverage arithmetic. It ignores waste, a second application, and a lawn that needs a different treatment.
WOLF-Garten SQ 120 at about £48.99 is about £0.41 per stated square metre, and SW 100 at about £49.99 is about £0.50. They are a poor default on value. The written reviews captured for them are marked as German, and the listings do not establish a GB or Northern Ireland authorisation number. A 360 m² bag is also poor value on a 60 m² lawn if most of it sits unused. Measure first, using the buying guide.
Best lawn feed when you want no herbicide
Westland SafeLawn is the stronger choice when the job is feed for a family lawn that stays in use. It was about £26.75, with 4.4 from 1,736 ratings. Westland describes it as a natural lawn feed at 35 g/m² and says children and pets can use the lawn after application.
That can suit a dog household. The granules are still not food, and the label still applies. Store the pack and apply the measured rate. Skip SafeLawn when you need weeds or moss killed. The fact sheet does not claim that, and comments reporting no weed kill match that limit.
Autumn option and a quick decision
For a large autumn lawn, the best value is Miracle-Gro autumn lawn care, 360 m², at about £24.00 with 4.6 from 520 ratings. The top pick is Miracle-Gro 4-in-1 autumn lawn care, 360 m². Its 5.0 rests on two ratings, and the part number conflicts with the stated pack size, so check the bag. Month and moss raking are on the autumn lawn feed guide. Skip the WOLF-Garten boxes as a default value choice unless the formulation, the label and the price all fit the job.
Common questions
Which lawn feed is best for weeds and moss in spring?
Miracle-Gro Complete 4 in 1 is the pick for an established, weedy lawn in spring. Its published label covers April to September and states a maximum rate of 35 g/m². Skip it for a lawn under six months old, if you want no herbicide, or if you cannot follow the label's access and application instructions.
Which lawn feed is best if I have a dog?
Westland SafeLawn is the better fit when regular family and pet access is the priority. Westland says children and pets can use the lawn after application, but you should still measure the stated 35 g/m² rate, store the product securely and follow its label. It is a feed choice, not a substitute for a weed-and-moss treatment.
Which pack is cheapest per square metre?
The large Miracle-Gro bags and Westland SafeLawn are approximately £0.07 per stated square metre using the compared price and coverage figures. The best value on the scores is Miracle-Gro autumn lawn care, 360 m², at about £24.00. This is coverage arithmetic, not a performance guarantee. On a small lawn a large bag can be poor value if much of it remains unused.
Is WOLF-Garten SQ 120 worth £48.99?
SQ 120 may suit a buyer who specifically wants that WOLF-Garten product, but it is not the best value here. At about £0.41 per stated square metre, it costs far more on coverage than the roughly £0.07 options. The listing data also does not verify a GB or Northern Ireland authorisation number, so check the current pack before buying.
Which autumn pack should I buy for a large lawn?
Miracle-Gro autumn lawn care, 360 m², is the best value and the firmer signal, at about £24.00 with 4.6 from 520 ratings. The top pick on the comparison scores is Miracle-Gro 4-in-1 autumn lawn care, 360 m², and that 5.0 rests on two ratings with an unresolved bag size. Confirm coverage against your measured lawn, and check the weight on delivery for the 4-in-1.
Is a 5.0-star lawn feed trustworthy?
A 5.0 score based on two ratings is weak evidence, because one further review can move it sharply. Treat the rating count, and whether the label matches the job, as more informative than the headline score. A product with 4.4 from 1,736 ratings has a broader opinion base. Ratings still cannot prove that it suits your lawn.
