Small sunny patches
You have one or two bare circles and you do not want a 3.4 kg sack. A 480 g full-sun box is enough if you can water for a fortnight. Skip it where the scar sits in shade.
Lawn repair seed comparison 2026
The best lawn repair seeds, compared.
Top pick: Gro-Sure multi-purpose, pack of 2 – Highest score in this comparison, 9.1 out of 10, from 158 amazon.co.uk reviews. Best value: Gro-Sure multi-purpose lawn seed, 10 m² – £7.00 for 300 g, with 10 m² in the title and 4.2 stars from 170 reviews. Updated October 2026.
A bare patch after a dry summer, a dog circle, or a thin strip beside the path is the usual reason to look for lawn repair seed. On amazon.co.uk the shelf splits into loose grass seed and patch mixes that add coir or fertiliser. None of the listings prints species percentages, so you judge a packet by whether the gram weight, the patch count and the item weight agree. The Royal Horticultural Society puts reliable sowing in spring and autumn, usually at about 15–25 g per square metre on prepared soil. Sowing steps are in our [how to sow lawn repair seed](/hub/seeds-and-plants/lawn-repair-seed/sub/lawn-repair-seed-how-to-sow) guide. Buyers are fixing small scars, dog circles, and lawns thinned by a dry summer.
A bare patch after a dry summer, a dog circle, or a thin strip beside the path is the usual reason to look for lawn repair seed.

The best lawn repair seeds in detail
Our view
This Gro-Sure twin listing is aimed at new lawns and overseeding, with 10 m² stated in the title and a built-in spreader praised by several reviewers. It carries a strong 4.3-star rating from 158 reviews and costs £14.00 for two items. The pack data is inconsistent, however: item weight is 540 g, unit count is 600 g and the listing says there are two items. Some buyers also felt the boxes looked underfilled or smaller than expected. A bird-deterrent treatment is useful during establishment, but no sunlight or germination guidance is shown. It can be convenient if you want two spreader boxes, though the uncertain weights make the single 300 g Gro-Sure listing easier to assess.
Pros
- Built-in spreader praised in reviews
- 4.3 stars from 158 ratings
- Bird-deterrent treatment
- Twin-pack convenience
Cons
- Conflicting 540 g and 600 g weight lines
- Reviews mention underfilled-looking boxes
- No sunlight or germination guidance
Best for: New lawn or overseeding work where two easy-spread boxes are convenient
Less suitable: Buyers who need an unambiguous weight and coverage calculation

Our view
Miracle-Gro Quick Gro supplies two 840 g boxes for new lawns or repairs that can be spread by hand or with a compatible spreader. The listing shows 4.3 stars, the highest rating in this set, but it is based on only 30 reviews. Its title states 28 m² and the bullets say the information applies to each unit, although the total coverage of the pair is not stated unambiguously. The four-day germination claim depends on watering, and sampled reviewers more often describe growth within a week than a uniform four-day result. At £27.98, it costs more upfront than several larger loose-seed packs. The clear spreading options and child-and-pet-friendly wording are useful, but the modest evidence base keeps it behind the top pick.
Pros
- Two 840 g boxes
- Can be spread by hand or spreader
- Child-and-pet-friendly listing wording
- 4.3-star headline rating
Cons
- Only 30 ratings
- High £27.98 price
- Pair coverage is not completely clear
- Four-day result depends on conditions
Best for: A medium repair or new area where you want boxed seed that works with a spreader
Less suitable: A budget repair or buyers who want a large review base behind the rating

How should it be spread?
The bullets say by hand or with a Miracle-Gro hand-held or wheeled spreader.
Did reviews match four days?
Six UK reviews include growth within a week and one report of about 20 percent after two and a half weeks.
Our view
Miracle-Gro EverGreen Fast Grass is the top pick here for a small sunny repair, pairing a £7.67 price with 4.2 stars from 5,144 reviews. The 480 g box is easy to handle and the listing explicitly specifies full sun. Its four-day germination message is a product claim rather than a result you should expect in every garden. In the sampled UK reviews, reported emergence ranges from about a week to a month, while some buyers saw no growth. The listing also does not provide a square-metre coverage figure, and one reviewer found that a box did not go far. Choose it for evidence and price, but not if your damaged area sits in persistent shade.
Pros
- Strong review base of 5,144 ratings
- Low £7.67 price
- Clear full-sun suitability
- Convenient 480 g box
Cons
- Four-day claim is not consistently reflected in reviews
- No square-metre coverage figure
- Unsuitable for a shaded repair
Best for: A small bare or thin patch in full sun where price and review evidence matter
Less suitable: Shade, large areas or anyone expecting reliable germination within four days

Common questions
Does the listing promise grass in four days?
The bullets say faster results with 4 day germination. In the first 50 UK reviews, several buyers report a week to a month, and some report no growth.
Will it suit shade?
The sunlight attribute is full sun. Shade is only a customer question.
Is there a coverage figure?
No square metres are printed. One review says one box does not go far.
Our view
The Grassias twin pack provides 3.4 kg of loose seed for repairing or overseeding a substantially larger lawn than the small retail boxes. Each 1.70 kg unit claims coverage of up to 87.5 m², and the listing gives a germination window of 10–15 days. A 4.2-star rating from 1,399 reviews provides broader buyer evidence than most products here. The £31.98 outlay is high for a single small scar, though the pack format can make more sense when several areas need work. Pet-friendly and paddock-safe wording is useful, but the listing does not provide species percentages. The title phrase “Defra Approved” should not be read as proof of a particular seed blend or performance standard.
Pros
- Large 3.4 kg twin pack
- Up to 87.5 m² claimed per unit
- Substantial review count
- Pet-friendly and paddock-safe listing wording
Cons
- High initial price for a small repair
- No species percentages in the listing
- No stated sunlight requirement
Best for: Overseeding or repairing several larger areas where a twin pack will be used
Less suitable: One small patch or buyers who need a fully stated seed composition

The bullet says 1.70 kg covers up to 87.5 m², and that the bullets apply to each unit.
Does the listing show a Defra label?
The title includes the words Defra Approved. No species percentages are on the listing.
Our view
This 1 kg ProGrass mix is the clearest specialist choice in the set for a bare patch in partial shade. At £12.79, it costs more than the small general-purpose boxes but provides more seed and a stated shade use. Its 4.2-star rating comes from 190 reviews, although many reviewer names and dates also appear on the related hardwearing listing. That overlap means the comments should not be treated as cleanly separated evidence for this exact blend. The listing does not state the grass species, a coverage area or a germination time. It is a more relevant choice than a full-sun seed for shade, but the sparse composition detail limits precise comparison.
Pros
- Explicit partial-shade suitability
- Useful 1 kg pack size
- Competitive £12.79 price for a specialist mix
Cons
- No species list
- No coverage or germination figure
- Review text overlaps another product listing
Best for: A shaded or partly shaded bare area where a general full-sun mix is unsuitable
Less suitable: Buyers who need verified species percentages or a stated coverage rate

Common questions
Is this a patch repair kit?
No. It is a 1 kg shade grass seed mix. Reviews describe using it on bare patches.
What grasses are in it?
The listing does not list species. The sunlight attribute is partial shade.
Can the reviews be added to the hardwearing box?
No. The shade listing and the hardwearing listing share many of the same reviewer names and dates.
Our view
The 2 kg ProGrass hardwearing pack offers a large quantity of loose seed for worn family-lawn areas in full or partial sun. Its £13.99 price is low for the stated weight, especially compared with carrier-heavy patch kits. The listing has 4.2 stars from 185 reviews and describes quick germination when the ground is prepared. It does not, however, state a square-metre rate or identify the grass species on the listing. Review text overlaps with the related shade product, including a shade complaint, so product-specific sentiment is uncertain. This is a sensible quantity-led buy for a broad repair, provided you can calculate the application rate from the pack when it arrives.
Pros
- Large 2 kg pack for £13.99
- Suitable for full and partial sun
- Hardwearing positioning for worn areas
Cons
- No stated square-metre coverage
- No species composition shown
- Review overlap weakens product-specific evidence
Best for: A larger worn area in sun or partial sun where loose seed offers better value than a patch kit
Less suitable: Small isolated circles or buyers who need a published sowing rate before ordering

Our view
This 300 g Gro-Sure box is a practical size for a small bare patch or light overseeding, with 10 m² stated in the amazon.co.uk title. Its £7.00 price and 4.2-star rating from 170 reviews make it the best-value option in this comparison. Review feedback is mixed: several buyers report quick growth after scarifying, while others saw no germination after two to four weeks. The bird-deterrent dressing may help where seed disappears quickly, but it does not replace good soil contact and regular moisture. The listing does not confirm a sunlight requirement or a pet-safety claim. Treat the 10 m² figure as a coverage claim rather than a guaranteed result, because preparation, weather and sowing rate still matter.
Pros
- Low £7.00 entry price
- 10 m² coverage claim in the title
- Bird-deterrent dressing
- Manageable 300 g box for small jobs
Cons
- Reviews include complete germination failures
- No confirmed sunlight guidance
- Pet friendly appears only as a question
Best for: A small bare patch or light overseeding where you want an inexpensive loose seed
Less suitable: Shaded sites or pet areas where you need an explicit suitability statement

Common questions

Pet friendly appears only as a customer question. The bullets do not answer it.
What do reviewers say about germination?
Among 25 UK reviews, several report quick growth after scarifying, and several report no growth after two to four weeks.
Our view
UK GROW’s £4.99 listing could suit one very small repair if the 100 g title and item weight are correct. It has 4.1 stars from 86 reviews and claims fast sprouting, with pet-safe and shade-tolerant language in the listing attributes. The product data is unusually inconsistent: the unit count says 5,000 g and the piece count says 100,000, neither of which fits a 100 g packet. Buyers also describe different packaging, including a tied clear bag without instructions and a resealable tub. There is no square-metre coverage figure or clear sunlight attribute to resolve the shade claim. The low price is attractive, but the listing conflicts make it harder to know exactly what will arrive.
Pros
- Lowest shelf price in the comparison
- Small quantity may avoid waste on one patch
- Pet-safe and shade-tolerant listing wording
Cons
- Severe conflict between weight fields
- Inconsistent packaging reported
- No coverage rate or clear sunlight attribute
Best for: One very small patch when the low price matters more than polished listing detail
Less suitable: Larger repairs or anyone who needs certainty about pack size and instructions

Our view
This 390 g Westland Gro-Sure box is a compact loose-seed option for a small new area or light overseeding. It costs £7.93 and includes a bird-deterrent treatment, while the listing gives the United Kingdom as the country of origin. The headline rating is 4.1 stars, but it comes from only five reviews. Only one UK review text was available, reporting good growth after sowing in a warm week before rain. There is no square-metre coverage figure, and the listing does not confirm that a spreader is included. It is reasonably priced, but the near-identical 300 g Gro-Sure option has clearer coverage and much stronger review evidence.
Pros
- Compact 390 g box
- Bird-deterrent treatment
- United Kingdom listed as country of origin
- Sub-£8 price
Cons
- Only five ratings
- No coverage area stated
- Spreader inclusion is not confirmed
Best for: A small repair where you want a compact UK-origin box with bird-deterrent treatment

Our view
Miracle-Gro Patch Magic combines seed, feed and coir in two jugs for quick treatment of several small bare spots. The binder and moisture-holding carrier make it easier to apply on slopes than loose seed alone. Its 4.0-star rating from 6,179 reviews is the largest evidence base in the comparison, but the score is lower than the leading loose seeds. Sampled reviews split between growth within about a week on damp patches and no growth after two to four weeks, with clumping also mentioned. The £24.00 price is difficult to justify for a broad area because much of the 2 kg weight is carrier rather than seed. The title, unit count and item-weight lines also differ slightly, so this is best judged as a convenience kit rather than by kilograms.
Pros
- Seed, feed and coir in one mix
- Binder can help on sloping patches
- Very large review count
- Two pourable jugs
Cons
- Costs more than comparable loose seed
- Mixed reports on germination and clumping
- Pack-weight lines do not fully agree
Best for: Several small awkward or sloping patches where an all-in-one carrier saves preparation
Less suitable: Large bare areas where loose seed and top dressing are more economical

The title is 1,015 g in a pack of 2. The unit count is 2,030 g and the item weight is 2 kg.
What do reviewers say about results?
In the first 50 UK reviews, praise clusters on small damp patches within about a week, and criticism clusters on no growth after two to four weeks and on clumped mix.
Our view
Gro-Sure Smart Patch is the only product here whose listing specifically says it neutralises the effects of dog urine while repairing dog spots. The 4.8 kg spreader box claims enough mix for 60 patches and says children and pets need not be excluded from treated areas. Its £17.98 price buys coated seed plus water-retaining and sowing granules, not 4.8 kg of pure grass seed. Evidence is relatively thin at 4.0 stars from 33 ratings, and the seven available UK review texts divide between reliable growth and no effect. The listing also does not state a patch diameter, making the 60-patch slogan difficult to compare directly with Doff’s 30 cm circles. It is the most targeted option for repeated dog spots, but loose seed is more economical for a continuous bare area.
Pros
- Only listing with a dog-urine neutraliser claim
- 60-patch coverage claim
- Spreader-box format
- Pets need not be excluded according to the listing
Cons
- Only 33 ratings
- Mixed review outcomes
- Patch diameter is not stated
- Most of the pack weight is not seed
Best for: Multiple small dog spots where a neutraliser and carrier are useful
Less suitable: A whole worn lawn or buyers comparing products by seed weight alone

Bullets say it neutralises dog urine and repairs dog spots, and that children and pets need not be excluded from treated areas.
How many reviews are on the listing?
The listing line is 4.0 from 33. Seven UK review texts split between growth and no effect.
Our view
Doff Patch Repair provides a precise application rate of 48 g for each 30 cm-diameter patch, with enough mix claimed for up to 21 patches. That makes its coverage easier to interpret than a vague patch count, and the arithmetic broadly matches the 1,000 g unit count. The £10.54 price sits below the larger all-in-one kits, while still including coated seed and fertiliser. Confidence is limited because the 3.5-star rating comes from only two UK reviews. One reviewer reported quick early growth and the other reported no success at that point, so there is no stable consensus. It is a measured option for small circles, but 21 patches should not be mistaken for 21 square metres.
Pros
- Clear 48 g rate per 30 cm patch
- Up to 21 small patches claimed
- Includes coated seed and fertiliser
- Lower price than larger patch kits
Cons
- Only two reviews
- Low 3.5-star headline rating
- Not economical for a broad bare area
Best for: A set of small, measurable 30 cm bare circles
Less suitable: Large patches or anyone wanting strong review evidence

No. The rate is a 30 cm diameter circle, not a square metre.
How many UK reviews are on the listing?
Two. One says it started growing quickly. One says no joy so far.
How we compared
We compared 12 lawn repair listings on amazon.co.uk and kept every one in the table. Scores follow the UK star rating, converted for ordering. They are not a lawn trial. Weights favour the job size, whether the gram lines agree, whether sun or dog damage matches the listing, the review count behind a claim, and whether you are paying for seed or for a carrier. Prices are the shelf figures on the listings, from £4.99 to £31.98.
1
Job size
25%A few small circles suit a patch mix. Tens of square metres suit a kilo-scale loose seed box. A 3.4 kg twin pack is the wrong buy for one small scar.
2
Honest weight
20%Prefer a title gram weight that matches the item weight. Conflicting lines, including 100 g against a 5,000 g unit count, should be flagged before you trust a coverage slogan.
3
Cause of the patch
20%Shade needs the shade listing, not a full-sun fast grass. Dog circles are the only place a urine-neutraliser line matters. Petrol, rubble and compaction are not seed problems.
4
Review volume
20%Read the review count against the claim. A 4.2 from 5,144 reviews and a 3.5 from 2 reviews are not equal evidence, even when both mention fast growth.
5
Carrier versus seed
15%A 4.8 kg patch box can be granules, coated seed and a binder. Do not compare that price per kilogram with naked grass seed.

Lawn repair seed buying guide
Choose lawn repair seed by the size of the scar, not by the loudest germination slogan. A few small circles are a different job from a lawn thinned across tens of square metres. This guide uses the same 12 amazon.co.uk listings as the table. Prices run from £4.99 to £31.98. No listing in the set prints species percentages. The Royal Horticultural Society still separates shade mixes from utility mixes for wear, and it puts reliable sowing in spring and autumn.
What is lawn repair seed?
Lawn repair seed on amazon.co.uk is loose grass seed used on bare patches, or a patch mix of seed plus coir or fertiliser. Buyers are fixing small scars, dog circles, and lawns thinned by a dry summer. The Royal Horticultural Society puts the reliable windows in spring and autumn, with seed usually at about 15–25 g per square metre on prepared soil.
Best for
- Small sunny scars and thin patches
- Dog urine rings where a neutraliser is named
- Shaded patches that still get some light
- Larger worn lawns that need loose seed by the kilo
Not ideal for
- Deep shade where a lawn may never hold
- Petrol, rubble or compaction, which seed will not cure
- One small circle if the only option in the basket is a 3.4 kg twin pack
Mistakes to avoid
- 1
Sowing onto thatch
Seed needs soil contact. Scattering it over thatch, or using an overseeding slogan on dead ground, is a common reason nothing comes up.
- 2
Trusting four days in cold or dry soil
Four-day germination is a listing claim. The RHS windows are spring and autumn, and October sowing in milder districts wants soil of at least about 7°C.
- 3
Washing the seed away
A harsh jet moves seed off the patch. Water gently, keep off the new growth, and do not water through a local hosepipe ban.
What to weigh up
Job size
HighJob size is the first split. A few small circles suit a patch mix. Doff states 48 g for a patch 30 cm across and claims up to 21 of those circles, which is not 21 square metres. Gro-Sure Smart Patch claims 60 patches in a 4.8 kg box of coated seed plus granules. Miracle-Gro Patch Magic puts seed, feed and coir in two jugs for small spots, including slopes. Once the bare area runs to tens of square metres, a kilo-scale loose seed box is the fit.
Honest weight and evidence
HighHonest weight is the second check, because none of these twelve listings prints species percentages. Prefer a title gram weight that matches the item weight. UK GROW shows 100 g on the title and the item weight, while the unit count says 5,000 g and the piece count says 100,000. The Gro-Sure twin listing shows an item weight of 540 g, a unit count of 600 g and two items, and several reviews say the box looked short of seed.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Worn family lawns
Feet and games have thinned a sunny or partly sunny area. You want hard-wearing loose seed at a real gram weight, not a carrier priced like seed. Use a urine neutraliser only where dog chemistry is the point.
Shaded scars
The bare patch is under a tree or beside a fence, so a full-sun fast grass is the wrong listing. A partial-shade mix is the closer match. Deep shade may still never hold a lawn.
Common questions about lawn repair seeds
What is the best lawn repair seed in 2026?
Miracle-Gro EverGreen Fast Grass, 480 g, is the top pick for a small sunny repair. It costs £7.67 and has 4.2 stars from 5,144 amazon.co.uk reviews. The listing says full sun and prints a four-day germination claim that many reviews do not match. Skip it for shade, for a urine neutraliser, or if you need a stated square-metre coverage. This is a listing comparison, not a lawn trial.
How much does lawn repair seed cost?
Amazon.co.uk shelf prices run from £4.99 to £31.98. Under £10 you will find UK GROW at £4.99, the Gro-Sure 300 g box at £7.00, Fast Grass at £7.67 and a 390 g Gro-Sure box at £7.93. Mid-range boxes sit between £10.54 and £17.98. Patch Magic, Quick Gro and Grassias cost £24.00 to £31.98. These are shelf prices in this comparison, not a UK-wide survey.
What should I check before I buy lawn repair seed?
Check the job size first. Small circles suit a patch mix, and tens of square metres suit a kilo of loose seed. Then check that the title weight matches the item weight, because several listings conflict. Match the cause: shade needs a shade mix, and dog urine is the reason to look for a neutraliser. Read the review count beside any fast-germination claim. Do not compare a carrier-heavy kit with naked seed on price per kilogram.
Should I buy a patch mix or loose seed?
For patches under about a square metre, a kit can be simpler. Doff states 48 g for a 30 cm circle and claims up to 21 patches. Patch Magic adds seed, feed and coir for small spots and slopes. Once the bare area is larger, loose seed plus a soil cover is the better-value route. ProGrass hardwearing is 2 kg at £13.99. Smart Patch’s 4.8 kg is mostly granules, so do not price it like naked seed.
When should I sow lawn repair seed?
The RHS puts the reliable windows in spring and autumn. A usual rate on prepared soil is about 15–25 g per square metre. October sowing in milder districts wants soil of at least about 7°C. Four-day claims assume warmth and moisture. Cold or dry soil is a common reason seed is slow or fails. Water gently, because a harsh jet can wash seed away. Do not water if a local hosepipe ban is in force.
Will lawn repair seed grow in shade or on dog spots?
If the patch is shaded, use a shade mix. ProGrass shade, 1 kg at £12.79, is the listing here that states partial shade. Deep shade may still never hold a lawn, because even a fescue mix needs light. For dog circles, Gro-Sure Smart Patch is the only listing that says it neutralises dog urine. “Pet friendly” only means the seller says you need not exclude pets. It does not mean urine will stop scorching the grass.
Why does lawn repair seed sometimes fail to come up?
Seed fails when it sits on thatch, when the ground is dead from petrol or rubble, or when the soil is compacted or stays sodden. An overseeding slogan does not repair those causes. Reviews on several boxes here report no growth after two to four weeks, and also quicker growth after scarifying. If brown patches spread in a wet mild autumn, or a second sowing has failed, call a professional rather than buying a third box.
Is lawn repair seed the same as grass seed for a new lawn?
Lawn repair seed here is loose seed sold for patches and overseeding, or a patch mix with coir or fertiliser. A full grass seed comparison is the better fit when you are sowing a whole new lawn rather than scars, dog rings and thin patches. None of these twelve listings prints species percentages. You still judge the packet by weight, coverage wording and the stated sun or shade use.
Our verdict
For a small sunny repair, Miracle-Gro EverGreen Fast Grass at £7.67 has the widest review base in this set, at 4.2 stars from 5,144 reviews. Treat the four-day line as a listing claim, and skip the box in shade. If you want the lowest price with a coverage figure on the title, the Gro-Sure 300 g multi-purpose box at £7.00 is the best value, and it is still a small-job packet. Larger worn areas point to kilo-scale loose seed, and dog urine rings are the only reason to choose the Smart Patch neutraliser.
