The best Wolf Garden lawn fertilisers, compared.
Top pick: Miracle-Gro 4-in-1 autumn lawn care, 360 m² Best value: Miracle-Gro autumn lawn care, 360 m² – It costs about £24.00 for a stated 360 m² and has 4.6 from 520 ratings. Moss is raked out after two weeks, and the listing does not state an NPK analysis. Updated October 2026.
A Wolf Garden lawn fertiliser search on amazon.co.uk returns two WOLF-Garten boxes and other lawn feeds. The other feeds stay because they are lawn fertiliser, not a tool, a seed-only mix or multipurpose plant food. Nine listings are compared here, from about £12.29 to £49.99. Judge them by the job, the month, the stated area, the pet wording, and whether nutrients or actives are stated. WOLF-Garten SQ 120, about £48.99, is a weed-and-feed for a stated 120 m², with 0.8% 2,4-D and 0.12% dicamba. SW 100, about £49.99, is a moss killer and feed for 100 m². The rest are Miracle-Gro Complete 4 in 1, Miracle-Gro autumn moss-and-feed, and Westland SafeLawn, which feeds and adds seed and does not claim to kill weeds or moss. The top pick is Miracle-Gro autumn lawn care, 360 m², with the highest score in this comparison (9.2 out of 10, from 520 amazon.co.uk reviews). Miracle-Gro autumn lawn care, 360 m², is the best value at about £24.00, with 4.6 from 520 ratings. This is not a laboratory test.

Personal buying guide
Question 1 of 2
When are you treating the lawn?
This listing describes a 12.6 kg Miracle-Gro autumn feed with NPK 6-5-10, iron sulphate and coverage up to 360 m². The formulation is well specified for September-to-November feeding and moss control. Its displayed 5.0 rating is based on only two ratings, so it is not robust evidence of better performance than the established alternatives. More importantly, the part number matches the 2.8 kg product and a listing question also refers to a 2.8 kg bag. The £24.75 price would be competitive if the 12.6 kg size and 360 m² coverage are correct, but both should be checked on delivery. This is the top-scoring product in this comparison, yet the unresolved listing identity prevents an unqualified recommendation.
Pros
Cons
Best for: A large lawn needing autumn feed and moss control, provided the delivered pack is verified as 12.6 kg.
Less suitable: Anyone who wants a proven listing, a substantial review base or certainty before delivery.
Specifications
Common questions
Is this a 12.6 kg or a 2.8 kg pack?
The pack data says 12.6 kg. The part number is the same as the 2.8 kg listing and one question on the page asks about a 2.8 kg bag, so check the weight when it arrives.
Will it treat moss?
The bullet says added iron sulphate helps kill and control moss. The season is September to November.
How many ratings does it have?
Two. The 5.0 score rests on two ratings, so it is a weaker signal than the 520 ratings on the other 360 m² autumn pack.
Miracle-Gro autumn lawn care feeds and treats moss across a stated 360 m² from September to November. The listing says moss should blacken within seven days and be raked out after two weeks, which sets clear expectations for the follow-up work. A 4.6 rating from 520 ratings is the strongest combination of rating level and meaningful review count among the large autumn packs. At £24.00, it also offers good stated coverage for the price and is the best-value pick in this comparison for a large lawn that needs autumn care. The NPK analysis and active ingredient are not stated, while the pack-weight fields disagree slightly at 12.8 kg and 12,600 g. Children and pets must remain off the lawn until the granules are thoroughly watered in and the area is dry.
Pros
Cons
Best for: A large moss-affected lawn needing good-value autumn feeding and moss control.
Less suitable: Spring and summer feeding, small lawns or anyone wanting a treatment with full nutrient details.
Specifications
Common questions
When does the listing say to apply it?
From September to November, to toughen the lawn for winter.
What happens to the moss?
The bullet says moss is killed within 7 days. It blackens as it dies and must be raked out after 2 weeks.
When can pets go back on the lawn?
Keep children and pets away until the granules have been watered in thoroughly and the area has dried.
Miracle-Gro Complete 4 in 1 treats weeds and moss while feeding up to 360 m² of established lawn. The listing names dandelions, white clover and plantain and limits application to April through September after frosts. Its 4.5 rating from 309 ratings is a more useful signal than the perfect score attached to only two ratings elsewhere in the set. At £24.94, it offers substantially more stated coverage per pound than either WOLF-Garten treatment. The listing does not state the NPK analysis or identify the active ingredients, and a spreader is recommended rather than clearly included. Children and pets must stay off until the granules have been watered in and the lawn has dried.
Pros
Cons
Best for: A large established lawn needing weed, moss and feed treatment between April and September.
Less suitable: Autumn use, feed-only care or buyers who need a spreader included.
Specifications
Common questions
When can you use it?
The bullet says April to September on established lawns, once frosts have gone.
Can children and pets use the lawn afterwards?
The listing says yes once the granules have been watered in and have dried, if you applied it as the label says.
Is a spreader in the box?
The listing does not say so. A bullet names a Miracle-Gro wheeled spreader, Multi Use Spreader or pre-filled spreader as ways to apply it.
Westland SafeLawn feeds and adds seed across a stated 400 m² without claiming to kill weeds or moss. Its 4.4 rating from 1,736 ratings gives it one of the strongest customer-evidence bases in the comparison. At £26.75 for 14 kg, it offers broad coverage at a much lower stated cost per square metre than the WOLF-Garten boxes. The listing says children and pets need not be excluded from treated areas, although the label should still be followed and granules must not be eaten. Several reviewers say it did not kill weeds or moss, which is consistent with the product's feed-and-thicken purpose rather than a failure of a stated killer function. Two reviewers also report finding little or no seed, so buyers focused on reseeding may prefer a separate grass-seed product.
Pros
Cons
Best for: A large family lawn needing feed and gradual thickening without a weedkiller claim.
Less suitable: Rapid weed or moss removal, precise reseeding or buyers wanting a stated Amazon NPK analysis.
Specifications
Common questions
Does it kill weeds or moss?
The bullets do not say so. They say stronger grass will start to outcompete weed and moss. Several reviewers say it did not kill either.
Is it safe for children and pets?
The bullet says children and pets need not be excluded from treated areas. One reviewer reports a dog unwell after use, so read the label.
Does it contain grass seed?
The bullet says added lawn seed. Two reviewers say they found little or none in the bag.
WOLF-Garten SW 100 feeds up to 100 m² while its 6% iron content is intended to tackle moss. The listing provides a useful February-to-October application window and states 14% nitrogen plus 5% potassium oxide. Its 4.4 rating comes from 529 ratings, although the written reviews captured here are marked as originating in Germany. At £49.99, it is the most expensive product in the comparison and covers far less ground than the large autumn treatments. The listing leaves the pet and child question unanswered, so the pack directions must decide when the lawn can be used again. This is a specialist small-lawn option, not the economical choice for broad coverage.
Pros
Cons
Best for: A small moss-affected lawn where you want a clearly stated nutrient and iron mix.
Less suitable: Large lawns, low-cost treatment or use before checking the pack's safety directions.
Specifications
Common questions
When does the listing say you can apply it?
The bullet says February to October. The pack is stated for 100 m².
Is it safe for pets?
The listing asks the question and does not answer it in the specification block. Read the label on the box.
Why does the listing show a volume in millilitres?
The liquid-volume field reads 3,500 ml, but the form is granules and the item weight is 3.65 kg. Treat the weight as the pack size.
This 2.8 kg Miracle-Gro Complete 4 in 1 pack covers a stated 80 m² and combines feed, weed control and moss treatment. The title names a handheld spreader, making it more convenient for a small lawn than a large refill bag. Its 4.4 rating from 444 ratings provides a solid body of customer feedback, while the £15 shelf price keeps the initial outlay low. Application is limited to established lawns from April to September, once frosts have passed. The listing does not state the NPK analysis or name the active ingredients, and the included-components field does not independently confirm the spreader. Children and pets should return only after the granules have been watered in and the surface has dried.
Pros
Cons
Best for: A small established lawn needing an all-in-one spring or summer treatment with easy spreading.
Less suitable: Large lawns, autumn feeding or anyone wanting a clearly documented formulation.
Specifications
Common questions
How big a lawn does this pack cover?
The title says 80 m². It is the small pack of the Complete 4 in 1 range.
Is the spreader included?
The title names a handheld spreader. The included-components line lists fertiliser, weed control and moss control only.
When is the lawn safe to use again?
The listing says children and pets can use it once the granules have been watered in and dried, if you applied it as the label says.
WOLF-Garten SQ 120 combines lawn feed with weed control for a stated 120 m², although another listing field says 100 without a unit. Its named 2,4-D and dicamba actives make it a targeted treatment rather than a routine feed. The 4.3 rating is supported by 2,335 ratings, but the written comments captured for this comparison are marked as reviews from Germany rather than UK customer accounts. At £48.99, it is much dearer per stated square metre than the larger Miracle-Gro bags here. The amazon.co.uk listing does not give a season, pet rule or confirmed UK pesticide authorisation, so you need to check the physical label before applying it. It suits a modest weedy lawn only when the pack carries the correct authorisation for where you live.
Pros
Cons
Best for: A modest lawn with weeds when the physical pack confirms the correct UK authorisation and directions.
Less suitable: Routine feeding, large lawns or buyers who cannot verify the pesticide label.
Specifications
Common questions
How many square metres does the box cover?
The bullet says 120 m². The coverage field says 100 with no unit, so check the box before you buy for a lawn near that limit.
Does the listing name a season or a pet rule?
No. The listing has no season line and no pet or child sentence. Read the label on the box before you use it.
Are the written reviews from UK shoppers?
No. The comments captured for this listing are marked Reviewed in Germany. The 4.3 rating from 2,335 ratings is the amazon.co.uk figure.
This 2.8 kg Miracle-Gro autumn treatment feeds an 80 m² lawn and uses iron sulphate for moss control. Its September-to-November window makes the intended season unambiguous, while the spreader named in the title should suit a compact lawn. The 4.3 rating is based on 233 ratings, a more substantial evidence base than the newer 80 m² autumn alternative. At £14.59, the upfront cost is low, though the large bag works out better by stated area. The listing does not supply an NPK analysis, and moss still needs to be raked out after it blackens. Children and pets should be kept away until the treatment has been watered in and the lawn is dry.
Pros
Cons
Best for: A small lawn needing a convenient autumn feed and iron-based moss treatment.
Less suitable: Large lawns, treatment outside autumn or feed-only care.
Specifications
Common questions
When should you use it?
The listing says September to November.
Does it kill moss?
The bullet says it kills moss within 7 days. The moss turns black and you rake it out after 2 weeks.
Is it safe for pets?
Keep children and pets away from treated areas until the granules have been watered in thoroughly and the area has dried.
This newer Miracle-Gro 4-in-1 autumn pack supplies NPK 6-5-10 with iron sulphate through a 2.8 kg spreader for up to 80 m². Its maximum rate of 35 g per m² and limit of two applications a year are more specific than many listings in the comparison. The £12.29 price is the lowest here, but the 3.8 rating rests on only five ratings. Two of those reviewers report burnt or blackened patches, so even spreading and strict adherence to the label matter. The listing also leaves the pet-safety question unanswered rather than giving a return-to-lawn rule. It is a low-cost, clearly formulated option, but its sparse and mixed feedback makes it a riskier buy.
Pros
Cons
Best for: A small lawn where you want a low-cost autumn formula and will measure the application carefully.
Less suitable: Buyers who want well-established feedback, broad coverage or explicit pet guidance.
Specifications
Common questions
How often can you apply it?
The bullet says up to twice a year at a maximum dose of 35 g per m².
How quickly will results show?
The bullet claims visible results in just 7 days. Two of the five reviewers report burnt or blackened patches.
Does the listing say it is safe for pets?
No. The question is asked on the listing and the bullets and specification block do not answer it. Read the label on the pack.
We compared nine amazon.co.uk listings, their UK star lines and the public sources named below. The scores on the product cards are the scores already recorded for those listings, divided by 10. Products Compared did not run a laboratory test. The weights below follow the buying checks for this set, in the order job, month, area, people and pets, then the label. They are not a laboratory formula, and they do not turn two ratings into a larger sample.
Job
30%The first check is whether you need to kill weeds, blacken moss and rake it out, strengthen roots for winter, or only thicken the grass. A feed-and-seed bag is not a weedkiller.
Month
25%Complete 4 in 1 says April to September, the SW 100 listing says February to October, and the autumn bags say September to November. The RHS says not to use leftover high-nitrogen summer feed in October.
Area
20%Measure length times width in metres and compare that with the stated 80, 100, 120, 360 or 400 m². The SQ 120 bullet says 120 m², while another field says 100 with no unit.
People and pets
15%Where a listing answers, weed-and-feed and iron products say keep children and pets off until the granules are watered in and dry. SafeLawn says they need not be excluded, and neither line means the granules are safe to eat.
Label and review evidence
10%Prefer a stated NPK analysis or named actives, a season and a rate. Two or five ratings are not several hundred, and no MAPP number in the WOLF-Garten files means this page does not call those boxes authorised.
Start with the job and the month, then check the stated area against the lawn you measured. A weedkiller, a moss treatment and a feed-and-seed bag are different products, and a high star line on two ratings is not the same evidence as several hundred.
Lawn fertiliser here means a product sold to feed a lawn, sometimes with a weedkiller, a moss treatment or grass seed in the same bag. On amazon.co.uk, a Wolf Garden lawn fertiliser search returns two WOLF-Garten boxes and other lawn feeds. Those other feeds stay because they are lawn fertiliser. A tool, a seed-only mix or a multipurpose plant food does not belong on this page.
Westland SafeLawn feeds and adds seed. It does not claim to kill weeds or moss. The WOLF-Garten boxes and Miracle-Gro Complete 4 in 1 are different jobs.
Complete 4 in 1 is for established lawns from April to September. Autumn listings in this set say September to November. The RHS says not to use leftover high-nitrogen summer feed in October.
Miracle-Gro 4-in-1 autumn lawn care, 360 m², shares a part number with the 2.8 kg listing and has two ratings. Check the weight on delivery, and do not read the German WOLF-Garten review sample as British opinion.
Decide the job before the brand. Weed-and-feed, moss control and feed-and-seed answer different problems, and an autumn bag is for September to November rather than a leftover spring mix. Complete 4 in 1 names April to September on established lawns. SW 100's own listing says February to October, which is wider than the February-to-August window on other SW sizes, so keep this box on its own wording. Then measure the lawn. Claims in this set run from about 80 m² to 400 m².
A useful listing states the NPK analysis or the actives, the season and a rate. SQ 120 names 0.8% 2,4-D and 0.12% dicamba. SW 100 names 14% nitrogen, 5% potassium oxide and 6% iron. Two autumn packs state NPK 6-5-10 and iron sulphate. Several Miracle-Gro listings leave the NPK blank. No MAPP number was in the WOLF-Garten saved listings, so authorisation has to be read on the physical pack.
Three typical situations, each with a recommendation from this comparison.
You want feed and seed without a claim to kill weeds or moss. Westland SafeLawn is 14 kg for a stated 400 m² at about £26.75, with 4.4 from 1,736 ratings. The listing says children and pets need not be excluded. That does not mean the granules are safe to eat, and two reviewers found little or no seed.
You have an established lawn with weeds from April to September and you will follow the label. Miracle-Gro Complete 4 in 1, 80 m², costs about £15.00 and has 4.4 from 444 ratings. The title names a handheld spreader, but the included-components line does not confirm it. Use WOLF-Garten SQ 120 only if the physical pack shows the correct authorisation. No MAPP number was in its saved listing.
You want autumn feed and moss control on a large lawn from September to November. Miracle-Gro autumn lawn care, 360 m², costs about £24.00 and has 4.6 from 520 ratings. Moss is raked out after it blackens. The listing does not state an NPK analysis. The two-rating 360 m² 4-in-1 listing is a poor match while its pack size is unresolved.
Match the bag to the job and the month. The top pick is Miracle-Gro autumn lawn care, 360 m², with the highest score in this comparison (9.2 out of 10, from 520 amazon.co.uk reviews). Miracle-Gro autumn lawn care, 360 m², is the best value at about £24.00, with 4.6 from 520 ratings and a September-to-November window. It does not state an NPK analysis. WOLF-Garten SQ 120 and SW 100 cost about £49 to £50 for roughly 100 to 120 m², and neither saved listing contained a MAPP number.
Miracle-Gro autumn lawn care, 360 m²
It costs about £24.00 for a stated 360 m² and has 4.6 from 520 ratings. Moss is raked out after two weeks, and the listing does not state an NPK analysis.
