Lawn patch repair kit or grass seed
Updated: October 2026
You are comparing a heavy tub with a lighter box on amazon.co.uk and assuming the heavier one repairs more lawn. A lawn patch repair kit or grass seed decision is about what is inside the pack, and about how big the bare ground is. The 4.8 kg figure on a patch tub can look more generous than a 2 kg seed box while containing less grass seed. This comparison is from the Products Compared editorial team, updated on 16 October 2026, using amazon.co.uk listings and manufacturer pages where a listing is silent. We did not run a laboratory trial. The full table sits on our [lawn repair seed comparison](/hub/seeds-and-plants/lawn-repair-seed).

A kit is seed plus a carrier
Miracle-Gro Patch Magic combines seed, feed, and coir. Love the Garden’s page for the 1,015 g jug describes that mix and a binder meant to hold a repair on a slope. The amazon.co.uk listing in our set does not print a patch count, so any count for that jug comes from the manufacturer page. Coir is the carrier that makes the pack feel substantial.
Gro-Sure Smart Patch uses coated seed with water-retaining and sowing granules. Westland Garden Health describes patches of about 45 cm. Our listing is the 4.8 kg size at about £17.98, titled around 60 patches. The 4.8 kg includes the carrier, so it does not beat a 2 kg seed box on seed weight.
Doff supplies coated seed plus fertiliser at 48 g for a circle 30 cm across. Twenty-one of those doses is about 1 kg, which lines up with the unit count, at about £10.54. A 30 cm circle is not a square metre. The RHS range for loose seed is about 15–25 g per square metre once you are sowing with a soil cover.
Small circles, not whole lawns
Use a kit when you have a few small circles and you would rather not buy topsoil on the same trip. Westland tells buyers to switch to seeding soil plus fresh lawn seed once the bare ground is larger than those patch sizes. Garden Ninja’s overseeding guide uses a rule of thumb that a kit suits patches under about a square metre, while plain seed plus a cover suits larger areas. That is a rule of thumb, not a trial of these listings.
Patch Magic at about £24.00 can be the simpler buy for a handful of scars around 45 cm, especially on a slope where the binder does a job loose seed will not do alone. Reviews split between growth in the first week on small damp patches and no growth after a fortnight. The coir does not replace watering. Smart Patch at about £17.98 for a claimed 60 patches is still a set of small circles. Using that tub on a 40 m² garden would be an expensive way to buy granules.
When loose seed is the better buy
Choose loose seed once the bare ground is a real area. The ProGrass hardwearing 2 kg box at about £13.99 carries no coverage slogan in our set, so you sow to the packet rate or the RHS guide of about 15–25 g per square metre and cover it with soil or compost. Compared with the 4.8 kg Smart Patch tub, you are buying more actual seed for less money. You supply the cover yourself. For a wide, flat, sunny repair, that trade is the sensible one. For three sloping dinner-plate scars, the kit can still be less fuss.
Fast Grass at about £7.67 is the lower-priced loose option here for sunny scars. It earns that best value role when the site is open and you can keep the surface moist. It is a weak swap if the scar is in shade, or if you wanted feed and coir in the same tub. The lawn repair seed buying guide separates shade, wear, and coverage claims. Our best lawn repair seed page names the top pick for the site you actually have.
Kit for circles, seed for an area
Use a kit for a few small circles, and loose seed once you are past about a square metre of worn ground. If the circles are dog urine, the carrier is not the deciding feature. Only one listing names a salt and ammonia neutraliser, which the dog urine patches guide explains. Keep feet off the new seedlings while they root.
Common questions
When is a lawn repair kit the simpler buy?
A kit is the simpler buy for a few circles around 30–45 cm when you do not want a separate bag of topsoil. Patch Magic adds seed, feed, coir, and a binder that can help on a slope. Smart Patch and Doff also wrap seed with carrier and feed, at about £17.98 and £10.54 in our amazon.co.uk set. The convenience fades once the bare ground is a wide worn area. Westland points those larger jobs to seeding soil plus fresh lawn seed.
Is 4.8 kg of Smart Patch more seed than a 2 kg box?
The 4.8 kg Gro-Sure Smart Patch listing is coated seed plus granules, at about £17.98, titled around 60 patches. The kilogram weight includes that carrier. The ProGrass hardwearing box is 2 kg of loose seed at about £13.99, with no coverage slogan, so you sow it by rate and cover it yourself. Compare the job, not the number on the tub. A heavier patch mix can still contain less grass seed than the lighter box.
How many patches does one Patch Magic jug claim?
Love the Garden’s page for the 1,015 g Patch Magic jug says up to about 13 patches of 45 cm, with seed, feed, coir, and a binder for slopes. That count is the manufacturer page. The amazon.co.uk listing in our set does not print it, so do not treat 13 as words on the Amazon title. At about £24.00, the jug suits a handful of those circles. It becomes expensive if you stretch the same jug across a large worn lawn.
Can I use Smart Patch on a whole lawn?
Westland keeps Smart Patch to patches of about 45 cm and says larger areas should be done with seeding soil plus fresh lawn seed. The brand’s worked example is the 1.2 kg size. Our listing is the 4.8 kg size at about £17.98, titled around 60 patches. Sixty small circles are still small circles, not a 40 m² overseed. The brand’s soil window is about 10–18°C, from April to September. Outside that, wait, or sow straightforward seed instead.
What is Doff’s 48 g actually measuring?
Doff states 48 g of coated seed and fertiliser for a circle 30 cm across. Twenty-one doses come to about 1 kg, which matches the unit count behind the listing at about £10.54. A 30 cm circle is much smaller than a square metre, so that 48 g is one patch dose of mix. For open ground, the RHS loose-seed guide of about 15–25 g per square metre, plus a soil cover, is the relevant comparison.
Do I still need to water a coir lawn repair mix?
Yes. Coir and water-retaining granules are meant to help the mix hold moisture, and they do not water the lawn for you. Patch Magic reviews in this set split between growth in the first week on small damp patches and no growth after a fortnight. A dry week explains those failures more often than the brand name. Use a fine rose, and delay the job if a hosepipe ban means you cannot keep the surface moist.
