Best fast growing grass seed: top pick and best value
Updated: 21 October 2026
The star lines in this set sit between 4.1 and 4.5, so a quick sort by stars will not tell you which bag to buy for a bald patch behind the patio. A 4.5 from nine reviews can sit above a 4.2 from several thousand, and three pack sizes can share one review block. This page names two criteria first, then the listing that meets each one, and who should skip it. Prices and the full table stay on the [fast growing grass seed comparison](/hub/seeds-and-plants/fast-growing-grass-seed). Species and coatings are on the [buying guide](/hub/seeds-and-plants/fast-growing-grass-seed/sub/fast-growing-grass-seed-buying-guide). Nothing here is a laboratory germination test.

How this page picks
The top pick is the most reviewed explicit fast-seed listing that still sits at 4.2 stars. That favours a large UK sample over a prettier average from a handful of texts. It does not treat a four-day slogan as a promise. The RHS puts ordinary germination nearer seven to ten days in early autumn or mid-spring. Shoots and a lawn you can use are different jobs.
Best value is the lowest unambiguous price per stated square metre. The listing must print an area, not an up-to bullet and not a kilogram with no rate. A cheap tub with no coverage cannot win, because there is no denominator. A £7.67 pouch is the wrong winner for 200 square metres. A 10 kg sack is the wrong winner for two dinner-plate patches. The overseeding page is where a thin existing lawn changes the rate.
Top pick for a small fast repair
On that rule, the top pick is Miracle-Gro EverGreen Fast Grass, 480 g, at £7.67, rated 4.2 from 5,144 amazon.co.uk reviews. Reviewers describe growth in about five to six days, shoots by about day seven when the four-day line was missed, and inch-high grass in ten days. The listing claims Headstart Gold and calls it pet friendly. The sunlight field says full sun. There is no species list and no printed area.
Skip it when you need a square-metre rate, and skip it for a large new lawn. One review had no growth after almost two weeks, and another still had large brown areas a week after scarifying. Quick GRO, two 420 g boxes at £10.76, is 4.3 from 157 and states 14 m² per box, on a much smaller sample. Wolf-Garten LR 25 has 4.1 from 7,578 and a stated 25 m² at £8.98, but it is sold as reseeding seed, and one UK review says the instructions are only in German.
Best value when the area is printed
Best value is Gro-Sure Aqua Gel, 10 kg, at £56.70 for a stated 250 m², about £0.23 per stated square metre. The listing is 4.2 from 260 reviews. Repeat buyers describe a visible difference by about 15 days and a thick lawn after scarifying. One review calls the blue coating bird-resistant.
Skip the sack for one small patch, and skip it if you need naked seed. Reviewers say much of the bag feels like husk. Some had no germination despite rain. The bullet mentions shade, and the sunlight field says full sun only. Wolf at £8.98 for 25 m² is about £0.36 per stated square metre, a better fit when 25 m² is the whole job. Grassias at £31.98 only looks cheaper if you accept up to 87.5 m² per 1.70 kg unit. That bullet is not a measurement, and the title says Defra approved without a certificate in the file. Sowing depth is on the how to sow page.
Ratings that should not decide
Doff’s 1 kg bag is £10.88 and 4.5 from nine reviews, with three short texts. One was written before any germination was seen. There is no coverage, no species and no day count, and a catalogue height of 20 metres is not a lawn.
ProGrass 1 kg (£11.44), 2 kg (£13.99) and 4 kg (£28.75) each show 4.2 from 185 reviews, and the texts match. Count them once. None prints an area. The 4 kg number-of-items field says 2, which is unresolved. UKgrow’s 20 m² pack at £9.99 names perennial ryegrass and red fescue. That is a reason to shortlist it, not a win on review volume. The UKGROW 100 g tub at £4.99 has no printed area.
Common questions
Which listing is the top pick and for whom?
EverGreen Fast Grass, 480 g, at £7.67, on the criterion of the most reviewed explicit fast listing at 4.2 stars, with 5,144 reviews. It suits a small repair when you can accept no printed area. It does not suit a whole large lawn, and the four-day claim is already missed in the review file. The sunlight field says full sun, and no species are named.
Which pack is best value for a large lawn?
Gro-Sure Aqua Gel, 10 kg, at £56.70 for a stated 250 m², about £0.23 per stated square metre. That is the lowest unambiguous rate here. Skip it for one small patch, and remember that reviewers describe coating weight as well as successful lawns. Some buyers had no germination despite rain and bird scarers.
Why is Doff’s 4.5 not the winner?
Because the line is 4.5 from nine reviews, with three short texts, and the listing has almost no specifications. One of those texts was written before the buyer had seen shoots. A larger 4.2 is the stronger evidence in this set. The catalogue height of 20 metres is not a lawn height.
Is Wolf better because it has more reviews than EverGreen?
Wolf has 7,578 reviews against EverGreen’s 5,144, at 4.1 rather than 4.2, and it states 25 m². It is a strong reseeding box. It is not the top pick on the fast-seed rule used here, and one review says the instructions are only in German. More reviews at a slightly lower star do not overturn that rule.
Does Grassias beat Gro-Sure on price per square metre?
Only if you treat up to 87.5 m² per 1.70 kg as a fact. This page does not. Gro-Sure’s 250 m² is a stated area. Grassias has more reviews, 1,399 against 260, which is a different strength, and its Defra line is not backed by a certificate in the file. The pair of bags is £31.98.
Is a top pick a lab test?
No. It is a rule applied to amazon.co.uk prices, printed areas and review counts in this set on 19 October 2026. The RHS timing is a check on slogans, not a score for any ASIN. Your soil, birds and the week you sow still decide whether seed comes up. No germination test was run for these listings.
