Best lawn sand: the fit for moss or for grit
Updated: October 2026
You want one bag from this amazon.co.uk shelf, and the star line is the wrong first filter. The best lawn sand in this capture is the listing that matches the job: a moss-control granule on an established lawn, or 0/4 mm graded sand after you spike. The [lawn sand comparison](/hub/fertiliser-soil-and-bark-mulch/lawn-sand) does not crown a laboratory winner. This page names a fit for each of the five kept ASINs and who should skip the two Scottish Aggregates bags if they wanted iron this week.

What best can mean on this shelf
Best here means the right form for the job you named, with a pack size you can finish. It does not mean the highest star average in the United Kingdom. Westland 16 kg, Vitax Green Up 4 kg, and Vitax Green Up 250 m² are moss-control granules in this capture. The two Scottish Aggregates rows are 0/4 mm graded sand. If you wanted moss to blacken, the sand bags are a skip even when a listing also mentions moss.
A 4.5 from 39 on the Vitax 250 m² pack is a thinner sample than 4.2 from 268 on Westland. The score of 90 is why that pack is the top pick. It is still seven United Kingdom texts. The 2.9 from 21 on both Scottish Aggregates ASINs is one shared file. If you have not chosen the job, use the lawn sand buying guide.
Moss-control granules in this capture
Westland (B01AUI5HVI) is the 16 kg title at about £20.91, coverage field 200, 4.2 from 268. Reviewers describe blackened moss, and also split bags, stones, and burnt grass. One review reports a red stain on Portland Stone. Fit it to an established lawn around that 200 figure. Skip it on turf under one year old.
Vitax Green Up 250 m² (B079NW7D9Y) is 20.2 kg at about £31.35, 4.5 from 39, score 90. Seven United Kingdom texts call it easy. One household said the second bag failed. The how-often question is unanswered. Buy it when the printed 250 square metres matches the lawn. Do not treat 4.5 as stronger evidence than Westland's 268 ratings.
Vitax Green Up 4 kg (B002Q07XOS) is about £10.95, 4.3 from 30, score 86. Coverage is Medium and the included line says 50SQM. This is the small-lawn box and the best value here. It will run short on a 200 square metre plot. Grams and weather sit on how to apply lawn sand. Blackening and return sit on lawn sand for moss.
Who should skip the graded-sand bags
Scottish Aggregates (B0DYNHLB74) is titled (1, 20kg) at about £14.99. The other listing (B0DYNDGBHZ) is titled (20, 20kg) at about £24.00. Both print 0/4 mm sand, up to 2.5 m² per 20 kg, and a lute, rake, or brush method. Both carry 2.9 from 21 ratings and the same ten United Kingdom texts. Reviews say the bags arrived as sand without nitrates. The £24 title is one bag: unit count 20,000 g, item weight 20 kg.
Skip both if the job is moss kill this week. A line about reducing moss does not turn additive-free sand into a ferrous-sulphate granule. Keep them only if you already wanted grit for aeration holes.
Pack clashes that change the buy
Westland's title and unit count say 16 kg; the item-weight row says 14.9 kg. If you planned 200 square metres at 80 g per square metre, a short bag is a coverage problem. Consumer Rights Act 2015 section 11 says goods must match their description.
Vitax 4 kg prints Medium coverage and an included 50SQM line, and a 4 litre field against a 4 kg title. Treat 50 square metres as the small-lawn reading. The (20, 20kg) title is a 20 kg listing at about £24.00, not a pallet. This page keeps 2.9 from 21 at about £14.99.
Common questions
Which kept listing is for moss on an established lawn?
Westland 16 kg, Vitax Green Up 4 kg, and Vitax Green Up 250 m² are the moss-control granules in this capture. Westland's sheet is for established turf, not grass under one year old. The two Scottish Aggregates bags are graded sand. Stars do not change that split.
Which kept listing is only graded sand?
Both Scottish Aggregates ASINs: B0DYNHLB74 at about £14.99 and B0DYNDGBHZ at about £24.00. They print 0/4 mm sand and up to 2.5 m² per 20 kg. Reviews say no nitrates. That is aeration or a thin dressing, not this week's mosskiller.
Should I buy the £24 (20, 20kg) title as twenty bags?
No. The listing shows a unit count of 20,000 g and an item weight of 20 kg. The title is a clash, not a pallet. You would pay about £24.00 for one 20 kg bag that shares its review file with the sibling at about £14.99.
Are the two Scottish Aggregates review files independent?
No. The file records the same 2.9 from 21 line, the same ten United Kingdom texts, the same 0/4 mm bullets, and the same image URL. Count that sample once.
Is 4.5 from 39 better evidence than 4.2 from 268?
No. 4.5 from 39 is a higher average on a thinner file. 4.2 from 268 is the deepest chemical sample here. The score of 90 on the 250 m² Vitax pack is a ranking inside this set, not a United Kingdom laboratory win.
Who should skip a chemical bag on turf under one year old?
Anyone with a lawn younger than twelve months, on Westland's sheet. New turf is the wrong place for a ferrous-sulphate granule at the home rate. Wait until the grass is established, or change the site instead of treating moss.
Who should skip sand if they wanted moss kill this week?
Anyone who searched lawn sand because the moss is already in the grass. The two Scottish Aggregates bags are 0/4 mm sand. Reviewers say they did not get nitrates. Buy a labelled granule, or do not treat.
