The best fast growing grass seeds, compared.
Top pick: Doff fast growing lawn seed, 1 kg Best value: Gro-Sure Aqua Gel coated seed, 10 kg – Lowest unambiguous pounds per stated square metre: £56.70 for 250 m², about £0.23. Reviews mention husk and some total failures. Updated October 2026.
Fast growing grass seed on amazon.co.uk is lawn seed sold for quick green cover, usually a hard-wearing mix rather than a fine bowling-green blend. You use it for bare patches, a thin lawn after a dry summer, or a new lawn you will mow often. The Royal Horticultural Society says a general-purpose lawn is perennial ryegrass with fescues and browntop, grows quickly, and germinates best in early autumn or mid-spring in seven to ten days. Quality is a named turf-type mix, a printed square-metre rate, and lawful certified seed, not a four-day slogan. Use the [fast growing grass seed buying guide](/hub/seeds-and-plants/fast-growing-grass-seed/sub/fast-growing-grass-seed-buying-guide) for the checks in order, then come back to the table. Hard-wearing mixes are ryegrass-led, quick, and need more mowing.

Personal buying guide
Question 1 of 2
How much lawn are you sowing?
Doff’s 1 kg fast growing lawn seed is £10.88 and almost a bare title: no coverage, no species, no coating and no day count. The listing line is 4.5 from nine reviews, and the raw file holds three short texts. One repeat buyer calls it good quality, and one review says it was quick growing and thick. A third review calls it good value before that buyer had seen any germination. That is too small a sample to rank it above packs with thousands of reviews. The catalogue height of 20 metres is not a lawn height and should not be read as a growth figure. Shade, water and pets are questions with no answers in the file.
Pros
Cons
Best for: You already know Doff’s mix from the packet in your hand and you only need a 1 kg top-up.
Less suitable: You are ranking seed from stars, or you need a stated area and a species list before you sow.
Specifications
Common questions
How much lawn does 1 kg cover?
The raw file does not say. There is no sowing rate.
Will it grow in shade, and is it pet friendly?
Both are questions with no answers in the raw file.
Why not treat 4.5 stars as the best score?
The listing line is 4.5 from 9 reviews, and the file contains three short texts. One buyer had not yet seen germination.
Miracle-Gro Quick GRO is sold here as two 420 g boxes, 14 m² each, at £10.76, with a listed pair weight of 840 g and a rating of 4.3 from 157 reviews. The bullet ties first shoots in four days to regular watering, and one review reports growth after four days. On a new-build lawn, another review describes thicker, greener grass in a couple of weeks when the box was followed, and a third found it useful after a hard summer. The same file includes bald patches the buyer expected to sow again, and no grass despite a barrier and netting against birds. Species are not named, and the question about all grass types is unanswered. The 4.3 is higher than EverGreen’s 4.2, on a much smaller sample, so this is a stated-area pair of boxes rather than the top pick.
Pros
Cons
Best for: You want two stated 14 m² boxes and you can water regularly while the seed takes.
Less suitable: You are choosing on star rating alone, or you need one small tub rather than a pair of boxes.
Specifications
Common questions
How much area is stated?
Each 420 g box is titled for 14 m². The pack contains two boxes and the listed weight is 840 g.
When does the listing claim first shoots?
The bullet says first shoots in 4 days when watered regularly. Reviews include both growth after 4 days and no grass despite netting.
Does it name the grass species?
No. The target is lawn grass. The all-grass-types question is unanswered.
Miracle-Gro EverGreen Fast Grass is a 480 g pack at £7.67, and it is the most reviewed explicit fast-seed listing in this set at 4.2 from 5,144 amazon.co.uk reviews. When conditions suit, reviewers describe visible growth in about five to six days, shoots by about day seven when the day-four claim was missed, and inch-high grass in ten days along a bare lawn edge. One before-and-after review shows green cover between mid-September and 1 October. The bullets promise four-day germination and a Headstart Gold coating, but the file has no square-metre rate and no species list, and the sunlight field says full sun. One buyer had no growth after almost two weeks, another still had large brown areas a week after scarifying, and a third did not receive the green EverGreen box they expected. It is the top pick here for a small fast repair on review volume, and the wrong pack if you need a printed area for a whole lawn.
Pros
Cons
Best for: You want the top pick for a small fast repair, chosen on review volume rather than a printed area.
Less suitable: You are sowing a large lawn and you need a stated square-metre rate before you buy.
Specifications
Common questions
Does this listing name the grasses in the mix?
No. The raw file asks what grass types it contains and does not answer. The sunlight field says full sun.
What germination time does the listing claim?
The bullets say faster results with 4 day germination and a Headstart Gold coating. UK reviews in the file include both shoots in about 5–7 days and no growth after nearly two weeks.
Is it described as pet friendly?
The special-feature field says pet friendly. The file has no urine or chemical-safety detail.
Grassias is a pack of two 1.70 kg units, listed weight 3.4 kg, at £31.98, rated 4.2 from 1,399 reviews and ranked 4 in Grass Seeds. A bullet says 1.70 kg covers up to 87.5 m², and the file says that figure applies to each unit, so the pair is a large up-to claim rather than a weighed test. Reviewers describe germination after about eight days and a healthy lawn at two weeks, abundant green growth once rain returned, and a garden recovered after a pool and a trampoline. A heatwave limited one result to some patches, and at least one buyer saw no grass. The title says Winter & Defra Approved, but the file has no certificate number. Species and shade are not answered. The 10–15 day results line is slower on the page than the four-day slogans, and closer to what several reviews actually timed.
Pros
Cons
Best for: You want a heavily reviewed large pair of bags and you can treat 87.5 m² as an upper claim, not a guarantee.
Less suitable: You need an unambiguous price per square metre, a species list, or proof of a Defra label.
Specifications
Common questions
How much area does the listing claim?
A bullet says 1.70 kg covers up to 87.5 m², and the raw file says that information applies to each unit in the pack of two.
Does the listing prove DEFRA approval?
The title says Winter & Defra Approved. The raw file has no certificate number or label photo.
Will it grow in shade?
The listing asks the question and does not answer it. No species mix is given.
The Gro-Sure Aqua Gel 10 kg bag states 250 m² at £56.70, about £0.23 per stated square metre, the lowest unambiguous figure in this set. Repeat buyers describe using it over several years after other seed, a visible difference by about 15 days, and a thick lawn after moss removal and scarifying. One review calls the blue coating bird-resistant. The same texts say much of the bag feels like husk or coating rather than naked seed, and some buyers had no germination despite rain and bird scarers. One detailed review says seed left on the surface, or buried too deep, did nothing. The bullet mentions shady areas as well as full sun, while the sunlight field says full sun only, and there is no species list. It is the best value large pack when you can use a stated 250 m², and a poor buy for one small patch.
Pros
Cons
Best for: You are sowing or overseeding a large area and you want the lowest unambiguous price per stated square metre.
Less suitable: You only have a small patch, or you need naked seed weight rather than a coated bag.
Specifications
Common questions
What area does this pack state?
The item type says 250 square metres. The bullet compares that area to 25 parking spaces.
Does the listing say it grows in shade?
The bullet says shady, hard-wearing, patchy or full sun. The sunlight field says full sun only. No species list is given.
Is it pet friendly?
The listing asks and does not answer. Moisture needs are listed as moderate watering.
ProGrass 2 kg from Lawns Direct is £13.99, so you get twice the 1 kg bag for a modest step up in price, still without a printed area. The listing is for hardwearing domestic lawns, parks and commercial grass when the ground is prepared, in March to May or August to October, and the sunlight field says full sun and partial sun. The 4.2 from 185 reviews is the same text block as the 1 kg and 4 kg files. Those reviews include bare patches up within about six days and a sowing that left no patches going into winter. They also include very little germination after careful preparation, and almost no new growth after weeks of care with a thin compost cover. Species are not named. The 2 kg bag is the mid size if you already accept that shared review file and you do not need a square-metre price.
Pros
Cons
Best for: You want more than 1 kg of this hardwearing seed and you can sow in the stated spring or autumn window.
Less suitable: You need a coverage figure, a shade mix, or a review sample that belongs only to the 2 kg bag.
Specifications
Common questions
Which grasses are in ProGrass?
The listing asks and does not say. Style name is hardwearing.
Can it be used in shade?
The sunlight field says full sun and partial sun. The shade question is unanswered.
Are these 185 reviews unique to this size?
The review texts match the other ProGrass sizes in this batch. The count is one shared block, not three separate samples.
ProGrass 1 kg from Lawns Direct is £11.44 and is sold for hardwearing lawns, parks and commercial areas when the ground is prepared, with a sowing window of March to May and August to October. The review line is 4.2 from 185, and the texts match the 2 kg and 4 kg files, so this is one sample rather than three. In those texts, bare patches are up within about six days for some buyers, and one timed sowing left no patches going into winter. Other buyers report very little germination despite preparation and watering, or almost no new growth after weeks under a thin compost cover. There is no printed square-metre rate and no species list. Sunlight is listed as full sun and partial sun. The 1 kg bag is the smallest of the three sizes, and you still cannot price it per square metre from the listing.
Pros
Cons
Best for: You want the smallest ProGrass bag for a prepared, sunny or partly sunny hardwearing lawn.
Less suitable: You need a stated square-metre rate, or you are adding the 185 reviews to the other ProGrass sizes.

ProGrass 4 kg from Lawns Direct is £28.75 and is the largest of the three hardwearing sizes, with the same March to May and August to October window and the same full sun and partial sun field. The 4.2 from 185 reviews matches the texts on the 1 kg and 2 kg listings, including patches up within about six days and, on the other side, very little germination after preparation and watering. There is still no printed square-metre rate, so £28.75 cannot be turned into a price per square metre from this file. The number-of-items field says 2 beside a 4 kg unit count, which is left unresolved, so it should not be read as a confirmed twin pack. Species, shade and pets are unanswered. It is a bulk bag of an unnamed hardwearing mix, and the review evidence is not three times the smaller bags.
Pros
Cons
Best for: You are buying several kilos of this hardwearing seed for a prepared sunny or partly sunny area.
Less suitable: You need a printed area, a confirmed single 4 kg bag, or reviews that apply only to this size.

The Gro-Sure multi purpose box states 10 m² from 300 g at £7.00, so a small new lawn or an overseed of that size has a printed area rather than a guess. One October review, after scarifying, moss removal and a little topsoil, describes a lush green result, and another buyer covered the seed with fine sand against birds and reported quick, strong growth. The bird-deterrent dressing is a listing claim; that sand review still treated birds as the buyer’s own job. Germination is not uniform in the texts: one review was slow before a good result, and another had nothing after four weeks. + 30% EF in the title is not defined in the file, and shade, pets and maintenance are unanswered questions. At 4.2 from 170 reviews it is a small-area box with a stated 10 m², not a large-lawn bag.
Pros
Cons
Best for: You are repairing or sowing about 10 m² and you want a stated area on the box.
Less suitable: You need a named species, a defined EF claim, or seed for a lawn much larger than 10 m².
Specifications
Common questions
What does + 30% EF mean?
The title includes that phrase. The raw file does not define it.
Will it grow in shade, and is it pet friendly?
Both are questions on the listing with no answer in the raw file.
How big is the stated area?
The title says 10 square metres. The listed weight is 300 g.
Wolf-Garten LR 25 states 25 m² from a listed 499 g at £8.98, and the listing line is 4.1 from 7,578 reviews, the largest count in this set. Reviewers describe shoots in about three days on bold patches where another seed had been patchy, a fledgling lawn within two weeks, and a usable lawn about two weeks after that. One review says the grass stands up to children and pets. The bullets claim 30% faster germination and about 70,000 shoots per square metre, which are seller figures, not a test in this file. Failures sit in the same set: no growth in one review that suspected bird seed, and a slow start in a warm, dry month. One UK review says the box instructions are exclusively in German, and the sunlight field says full shade while the item type says all lawn types, with no species list to settle either line. It is a reseeding box with a printed 25 m², not the top pick on the fast-seed review criterion.
Pros
Cons
Best for: You are reseeding about 25 m² and you want the largest review count in this set, with a printed area.
Less suitable: You need English instructions on the box, or a shade mix you can check against a species list.
Specifications
Common questions
What area does LR 25 state?
The bullets and item type say 25 m². Listed weight is 499 g, with a 500 g unit count.
Does the listing say the instructions are in English?
The listing asks if instructions are included and does not answer. One UK review says the box instructions are exclusively in German.
Is the full-shade field a shade mix?
The sunlight field says full shade. The item type says all lawn types. No species list is in the raw file.
The UKgrow 20 m² pack is the only listing in this set that names the grasses: perennial ryegrass and red fescue, with no percentages, at a listed 600 g and £9.99. The bullet says germination in five to seven days, and one review reports sprouts at about five days, with fine growth that knitted into an existing lawn used as a patch repair. Another review was slower in hot, dry weather, and one buyer had nothing and was waiting for a refund. A UK review says the packet was very small and arrived with no label or instructions. The listing claims shade and sun, plus pet and child safety, which are feature words rather than a measured mix. At 4.1 from 214 reviews it is the pack you open when you want the species named, though the 20 m² figure is still the seller’s stated area.
Pros
Cons
Best for: You want a stated 20 m² pack that actually names perennial ryegrass and red fescue.
Less suitable: You need mix percentages, printed sowing instructions, or seed for much more than 20 m².
Specifications
Common questions
Which grasses does this pack name?
The product-type field says perennial ryegrass and red fescue. Percentages are not given.
Does it include instructions?
The listing asks. One UK review says the packet was very small and had no label or instructions.
What germination time is claimed?
The bullet says 5–7 days. One review reports sprouts at about 5 days; another says hot, dry weather was slower.
The UKGROW 100 g tub is a £4.99 patch pack, and reviewers who used it on small bare spots report shoots at about six days or germination around ten days. One buyer used it for a new lawn and for overseeding where other shop seed had failed, and another liked the resealable lid because mice in a shed had not opened it. The listing says it sprouts in days and calls the blend shade tolerant, drought resistant and pet-safe, but it does not name the grasses or print a square-metre rate. Results are uneven: one review describes some areas coming up and others staying bare after compost and nightly watering. The file also includes a review of a 5 kg box, which is not this 100 g title, and the unit-count field says 5,000 g against a 100 g item weight. At 4.1 from 86 reviews it is a small repair tub, and you cannot treat the feature list as a measured mix.
Pros
Cons
Best for: You have one or two small patches and you want the cheapest tub in this set.
Less suitable: You need a stated square-metre rate, a named grass, or enough seed for a whole lawn.
Specifications
Common questions
Is this a 100 g pack or 5 kg?
The title and item weight say 100 g. A unit-count field says 5000 g. One review talks about a 5 kg box. Treat the title as 100 g.
Does it name the species?
No. Shade tolerance, drought resistance and pet safety are feature words only.
How fast does the listing say it sprouts?
The bullet says just days, with no number. Reviews mention about 6 days and about 10 days.
Twelve amazon.co.uk listings were scored for this page. Weights sum to 100. Shelf date in the method file is 19 October 2026. A four-day bullet is not scored as a usable lawn. There was no lab test. The three ProGrass sizes are not scored as three separate samples of 185.
Amazon evidence

Listing usefulness
35%A printed square-metre area, a named species, and a light field that does not contradict the bullets score higher. A missing rate, an unexplained +30% EF, or a 20 metre height field is deducted.
Review outcome
20%UK reviews that describe shoots in a stated number of days score higher than a file that also records total failure, a heatwave miss, or a German-only instruction panel.
Value
15%Shelf price in GBP against a stated area. A low price does not score here when no square metres are printed. An up-to area that is only a bullet is not the cheapest unambiguous rate.
The checks run in this order: a printed area, the species if it is named, the light, coating versus naked weight, then the review sample, then price per stated square metre. The table is the twelve packs. A four-day slogan is not a usable lawn.
Fast growing grass seed on amazon.co.uk is lawn seed sold for quick green cover, usually a hard-wearing mix rather than a fine bowling-green blend. UK buyers use it for bare patches, thin lawns after a dry summer, and new lawns they will mow often. The RHS says a general-purpose lawn is perennial ryegrass with fescues and browntop, grows quickly, and germinates best in early autumn or mid-spring in seven to ten days. Hard-wearing mixes are ryegrass-led, quick, and need more mowing.
The RHS window is seven to ten days in early autumn or mid-spring. EverGreen reviews include both early shoots and no growth after almost two weeks. Shoots are not a lawn you can use.
The 1 kg, 2 kg and 4 kg files share one 4.2-from-185 review block. Adding the counts treats one sample as three.
Doff’s 20 metres is not a lawn height. Wolf’s full-shade field conflicts with all lawn types, and there is no species list behind it.
A printed square-metre rate comes first. Gro-Sure states 10 m² or 250 m². Wolf states 25 m². Quick GRO states 14 m² per box. UKgrow states 20 m². Grassias up to 87.5 m² is a bullet on each 1.70 kg unit. ProGrass, EverGreen 480 g, the 100 g tub and Doff print no coverage, so they cannot be priced per square metre from the file. Fast cover in the UK is perennial ryegrass. Finer, slower, more shade-tolerant lawns lean on red and hard fescue.
Aqua gel on the Gro-Sure 10 kg bag and Headstart Gold on EverGreen are seller claims about moisture and speed. Reviews of the 10 kg bag say much of the weight feels like husk. Use the printed area, not the kilogram alone. A bird-deterrent dressing does not replace your own cover if birds are already taking the seed. Prefer a large review count over a tiny 4.5. EverGreen is 4.2 from 5,144. Wolf is 4.1 from 7,578. Grassias is 4.2 from 1,399. Doff is 4.5 from 9, with three short texts.
Three typical situations, each with a recommendation from this comparison.
You want a small box and a moist week, chosen on review volume rather than a printed area. EverGreen Fast Grass is 480 g at £7.67, 4.2 from 5,144 reviews. Reviews include shoots in about five to seven days and also a miss of the four-day claim. There is no square-metre rate.
You are sowing or overseeding a large lawn and you want the lowest unambiguous price per stated square metre. Gro-Sure Aqua Gel is 10 kg, £56.70, 250 m² stated, 4.2 from 260 reviews. Reviews mention husk and some total failures. It is a poor buy for one small patch.
You want the only pack here that names perennial ryegrass and red fescue. UKgrow is 600 g, £9.99, 20 m² stated, 4.1 from 214 reviews. Percentages are not given. One review found no label or instructions, and one buyer had nothing.
The top pick is Miracle-Gro EverGreen Fast Grass, 480 g at £7.67, 4.2 from 5,144 reviews. It is the most reviewed explicit fast listing. It prints no area, and reviews miss the four-day claim. The best value is Gro-Sure Aqua Gel, 10 kg at £56.70, with 250 m² stated, about £0.23 per stated square metre, and 4.2 from 260 reviews. Reviews describe husk and some total failures. Wolf-Garten LR 25 has the largest count, 4.1 from 7,578, and states 25 m². Only the UKgrow 20 m² pack names perennial ryegrass and red fescue. A 4.5 from nine Doff reviews does not outrank these.
Gro-Sure Aqua Gel coated seed, 10 kg
Lowest unambiguous pounds per stated square metre: £56.70 for 250 m², about £0.23. Reviews mention husk and some total failures.
