The best lawn lime bags, compared.
Top pick: Topline garden lime and Epsom salt Best value: Levington Garden Lime 3.5 kg – Lowest documented price per kilogram of lime alone after the top pick, about £3.28 per kilogram at about £11.49. Updated October 2026.
Lawn lime is ground limestone, usually calcium carbonate granules, that you use to raise the pH of acid soil. In a UK garden you buy it when a soil test shows the lawn is too acid for the grass you want, so grass can use nutrients more easily. You tell a suitable bag from a poor one by the chemical, the rate, the seller name and the pack. It should be carbonate, not builders' hydrated lime. The rate should name the soil, the seller name should match the carton, and the pack should fit the area. The Royal Horticultural Society treats about pH 6.5 as the usual garden figure and says not to lime at pH 7.0 or higher. Moss after spreading is not proof the soil needed lime. A test inside three months of lime, fertiliser or manure can mislead. Soil that fizzes with vinegar already has free carbonate, so lime is the wrong product. How to read a bag is set out in the [lawn lime buying guide](/hub/fertiliser-soil-and-bark-mulch/lawn-lime/sub/lawn-lime-buying-guide).

Question 1 of 2
What do you need from the listing?
Topline sells 4 kg garden lime with 1.5 kg Epsom salt and a card at about £18.95, item weight 5.5 kg, country of origin the United Kingdom. The title does not name a lawn. Lime bullets name tomatoes, broccoli, cauliflower, cabbage, trees, shrubs and flowers, and they describe calcium and magnesium. The salt is sold as a high-magnesium foliage feed you can water on. The star line is 5.0 from 1 rating with no review text, so that score is not a quality finding. Indoor use and pet safety appear as unanswered questions. Coverage is stored as Medium. This is a two-job bundle, not a straight lawn-lime bag.
Pros
Cons
Best for: A vegetable bed if a soil test already asked for both carbonate lime and extra magnesium.
Less suitable: A family lawn that only needs calcium carbonate, or anyone treating one 5.0 as proof.
Specifications
Common questions
Is this lime on its own?
No. The bundle is 4 kg garden lime soil conditioner, 1.5 kg Epsom salts, and a Topline card. Item weight is 5.5 kg. The number of items is 2.
Does the title name a lawn?
No. The lime bullets name tomatoes, broccoli, cauliflower, cabbage, trees, shrubs and flowers. The listing asks about indoor plants and pet safety. Neither is answered.
What is the Amazon rating?
5.0 from 1 rating. There is no review text in the saved listing. Country of origin is the United Kingdom.
Westland Lime Soil Conditioner arrives as a pack of two 4 kg bags, item weight 8 kg, at about £19.98, and the brand field matches Westland Horticulture. Across 974 amazon.co.uk ratings the line is 4.4, and this file holds 50 United Kingdom review texts. Reviewers often say the granules or small balls are easy to spread and that they used them on vegetables, clay allotments, and lawns even though the title does not name a lawn. The same texts keep returning to a cardboard box that splits and dumps lime dust, and to granules that stayed on the lawn after heavy rain. The listed rate is 1–2 handfuls, 35–70 g per square metre, dug in, which is not Westland's 10 g FAQ on the brand site. About £2.50 per kilogram on the 8 kg weight is the lowest documented lime-alone unit price here. It is the top pick in this set because the seller, the kilograms, and a real UK review sample all sit on the same page, not because 4.4 is a laboratory result.
Pros
Cons
Best for: A tested acid bed or lawn if you will follow the bag in your hand and expect dusty cardboard.
Less suitable: Ericaceous plants, which the listing does not clear, or anyone who needs a sealed sack and a single official gram rate.
Specifications
Common questions
How do you apply it?
The listing says dig in, and the bullets say it is worked into the soil. The stated rate is 1–2 handfuls, 35–70 g per square metre.
Is it safe for ericaceous plants?
The listing asks that question. The bullets do not answer it. Pet safety is not stated in the saved listing.
What is in the pack?
Two units. The title says 4 kg each and the item weight is 8 kg. The brand is Westland. amazon.co.uk shows 4.4 from 974 reviews, and the file holds 50 UK review texts. The title and bullets do not name a lawn.
Encap Fast Acting Lime, model 10612-6, is listed at about £35.06 for 1.13 kg of fine lime aimed at lawn grass, with bullets stating 400 sq ft. That is about £31 per kilogram, far above the UK 3.5–4 kg bags in this set. The amazon.co.uk star line is 4.4 from 131 ratings, but the 37 review texts in the file are from the United States, not UK lawn opinion. A liquid-volume field of 2.5 litres sits on a product the bullets describe as bagged. Pet safety and grass types are unanswered questions. US reviewers often mention tomato blossom-end rot. This comparison will not claim a bag cures that. It is a small imported pack, not a family-lawn buy on price per kilogram.
Pros
Cons
Best for: A tiny patch if you already know this US SKU and accept the price per kilogram.
Less suitable: A UK family lawn, or anyone treating the 131 reviews as British opinion.
Specifications
Common questions
What coverage does the listing state?
The bullets state 400 sq ft. The item weight is 1.13 kg. A liquid-volume field of 2.5 litres is also present, on a product the bullets describe as bagged lime.
Does the listing say it is for lawns?
Target species is lawn grass. The bullets describe a fine lime with an AST polymer for garden application, and they claim a pH change. No measured result is in the saved listing.
Do the stored reviews answer pet safety?
The listing asks whether it is safe for pets. The saved listing does not answer that. The star line is 4.4 from 131 ratings. The review texts in the file are from the United States, not the UK.
Jolly Gardner Fast Acting Lime from Oldcastle is pelletised limestone at about £123.16, item weight 14.1 kg, titled for 5,000 sq ft of lawn grass. The brand field matches OLDCASTLE LAWN & GARDEN. One bullet claims it protects lawns from moss and bare spots caused by low pH. There is no evidence block in the file. How often to apply, and whether it suits all grass types, are unanswered. There is no Amazon rating and no review text. About £8.73 per kilogram is cheaper than Encap and still several times the Westland twin pack. This is a large imported pellet bag with a US area claim, not a checked UK garden-centre rate.
Pros
Cons
Best for: Someone who specifically wants this US pellet SKU and will convert the area themselves.
Less suitable: A small UK lawn, or anyone who needs reviews or a grams-per-square-metre label.
Specifications
Common questions
What area does the title cover?
The title says 5,000 sq ft. The item weight is 14.1 kg. The form is pellets. The number of items is 1.
Does the listing claim it helps with moss?
One bullet claims it protects lawns from moss and bare spots caused by low pH. There is no evidence block in the saved listing. How often to apply is a question only.
Is there an Amazon rating?
No review line and no review texts are in the listing file. Target species is lawn grass. Whether it suits all grass types is unanswered.
The title is Levington Garden Lime 3.5 kg for lawns, fruit and vegetables at about £11.49, and the item weight in the file is 3.5 kg. The brand and manufacturer fields say MURIEL BARGAINS, so the seller name does not match the carton name. Bullets describe dust-free granules for hand or a broadcast spreader in autumn or early spring, and they claim less moss and a use against club root. Those are listing claims only. There is no Amazon rating and no review text. The unit count is 3,600 g, close to but not the same as 3.5 kg. At about £3.28 per kilogram of the stated 3.5 kg it is the cheapest documented single lime bag in this set, which is why it carries the best value mark, not because anyone here tested the granules.
Pros
Cons
Best for: A small lawn or plot if you will check the bag is Levington 3.5 kg and then use that bag's own rate.
Less suitable: Anyone who needs a matching brand field or a UK review sample.
Specifications
Common questions
What pack size does the title give?
3.5 kg. The item weight is 3.5 kg. The unit count is 3,600 g, which is close but not the same. Included components say LEVINGTON LIME 3.5KG.
Does the listing name lawns?
Yes. The title names lawns, fruit and vegetables. Bullets also claim a use on professional turf, less moss, and a use against club root. Those are listing claims only.
How does the listing say to apply it?
Dust-free granules by hand or with a broadcast spreader, in autumn or early spring. The item-form field is not filled in. The brand field is MURIEL BARGAINS, while the title says Levington. There is no Amazon rating in the file.
The amazon.co.uk title is Westland Garden Lime 4 kg granules for flowers, vegetables, lawns and garden soil at about £10.99, while the brand and manufacturer fields say MURIEL BARGAINS. The unit count is 1,500 g against that 4 kg claim, so you cannot treat the shelf price as a known price per kilogram. Included components say Organic Perlite Compost, which is not garden lime. There is no customer-review line and no review text in the file. The bullets say the granules can go on through the year, with autumn before frost mentioned, and they name calcium and magnesium without a rate. This is the cheapest title in the set, and it is the weakest listing to trust before the parcel arrives.
Pros
Cons
Best for: Someone who will confirm the carton is Westland garden lime and the weight matches 4 kg before keeping it.
Less suitable: Anyone who needs a matching seller name, a known kilogram price, or UK reviews.
Specifications
Common questions
What weight does the listing give?
The title says 4 kg granules. The unit count says 1,500 g. The listing does not say which figure to use.
What does the included-components field say?
Organic Perlite Compost. That conflicts with a garden lime title. The item form is granules. The model number is 20600101.
Does the title include lawns?
Yes. Specific uses include lawn treatment, neutralising acidic soil, and vegetable garden soil improvement. The brand field says MURIEL BARGAINS. There is no Amazon rating in the file.
The title is Levington Garden Lime 2 × 3.5 kg at about £21.20, while the brand field says Fixtures Business & Homewares and the manufacturer is Fixtures. The unit count is 3,500 g against a 7 kg title and a part number LevLime7kg, so the delivered kilograms are not settled on this page. Bullets also say All Round Plant Food and plant-food granules, and included components say Plant Food. There is no how-to-apply field, no lawn in the title, and no Amazon rating. Country of origin is the United Kingdom. Until the carton matches the title, this is a listing to skip rather than a twin-pack bargain.
Pros
Cons
Best for: Only if the delivered bags are clearly Levington lime and the weight is 7 kg.
Less suitable: Anyone buying from the listing fields alone, or looking for a lawn rate.
Specifications
Common questions
How much lime does the title claim?
The title says 2 × 3.5 kg. The unit count is 3,500 g. The part number is LevLime7kg. There is no item-weight field.
Who is named as the brand?
The title names Levington. The brand field says Fixtures Business & Homewares and the manufacturer is Fixtures. Country of origin is the United Kingdom.
Do the bullets only describe lime?
The bullets also say All Round Plant Food, Levington Lime 7kg, plant food granules, and improves soil fertility. How often to apply, and whether it helps with soil acidity, are questions only. There is no Amazon rating in the file.
Seven amazon.co.uk listings were scored from the stored pages and the UK review notes already on file. Shelf date 19 October 2026. There is no laboratory test. The Royal Horticultural Society, the Fertilisers Regulations 1991, and maker label pages are context for pH, chemicals and rates. They are not a score for these bags. Price per kilogram is not inside the score. It decides the best value on its own, and only on a lime-alone listing with a stated kilogram weight, excluding the top pick. A 4.4-star row does not mean the bag is the right chemical for your soil. The highest score is the top pick. The weights below sum to 100.
UK buyer evidence
40%Stars count only with review texts from the United Kingdom on that file. Westland at 4.4 from 974, with 50 UK texts, starts high and then loses points for split boxes and granules left on the lawn after rain. Texts marked as the United States, as on Encap, are not a UK sample. A line of 5.0 from 1 review and no text, or no customer-review line at all, is a gap, not a one-star result.
Followable UK rate
25%A printed gram rate plus a method scores when that method is dig in, including where it disagrees with the brand's own FAQ. Hand or spreader with a season and no grams scores lower. A US square-foot coverage with no method scores lower still. No rate and no method is the bottom of this block. Do not copy one brand's grams onto another bag.
Listing integrity
25%Brand field, kilogram claim and lime alone should match the title. A clean Westland twin pack at 2 × 4 kg and 8 kg item weight scores high. A seller name that is not the carton brand, a unit count that fights the kilogram title, or included components that say compost or plant food, scores low. A lime-plus-Epsom bundle cannot take the full lime-alone mark.
Lawn job named
10%Lawns or lawn grass in the title or the target species scores high. A soil conditioner that never names a lawn scores low, even when UK reviews mention turf. Naming a lawn does not by itself make the chemical or the rate right.
Test the soil and name the chemical before you rank a star line. Prices below are amazon.co.uk shelf prices on 19 October 2026. This is not a laboratory test.
Lawn lime in UK garden centres is ground limestone, calcium carbonate, usually as granules. You buy it to raise the pH of acid soil so grass and other plants that are not ericaceous can use nutrients more easily. The Royal Horticultural Society treats about pH 6.5 as the usual general-purpose garden figure and says not to lime at pH 7.0 or higher. Fine grasses prefer slightly more acid conditions than a ryegrass family lawn.
A test inside three months of lime, fertiliser or manure can mislead. At pH 7.0 or higher, or if the soil fizzes with vinegar, lime is the wrong product.
Westland's FAQ is 10 g per square metre. One listing of that style prints 35–70 g dug in. Levington uses a clay, loam and sand table. Keep lime off recent manure or urea.
The Royal Horticultural Society does not treat lime as the way to remove moss. A greener week, or a moss bullet, is not proof the soil needed lime.
Start with a soil test taken outside the three months after lime, fertiliser or manure. The Royal Horticultural Society treats about pH 6.5 as the usual garden figure and says not to lime at pH 7.0 or higher. Fine grasses prefer slightly more acid conditions than a ryegrass family lawn. If the soil fizzes with vinegar, free carbonate is present and lime is the wrong product. Moss, or a greener week after spreading, is not a reason to buy. The chemical is calcium carbonate.
The brand field, the kilogram claim and lime alone should match the title. In this set the Westland twin pack does: 2 × 4 kg, item weight 8 kg, brand Westland, about £19.98, about £2.50 per kilogram. Two titles that say Westland or Levington are filed under other seller names. One unit count says 1,500 g against a 4 kg title, and included components say Organic Perlite Compost. Another says 3,500 g against a 2 × 3.5 kg title, and the bullets also say plant food.
Three typical situations, each with a recommendation from this comparison.
You want a 3.5–4 kg granule bag, and a reason to stop if the test is already near 6.5. The listing titled Levington Garden Lime 3.5 kg is about £11.49, with item weight 3.5 kg, about £3.28 per kilogram. The brand field says MURIEL BARGAINS and there is no review line. Bullets say hand or a broadcast spreader in autumn or early spring. Use the rate on the bag you receive.
On clay you may be liming a bed, sometimes for clubroot, and you must not swap a lawn sprinkle for a digging-in rate. Westland Lime Soil Conditioner, pack of two, is about £19.98, item weight 8 kg, with 35–70 g per square metre dug in. amazon.co.uk shows 4.4 from 974 reviews. The title does not name a lawn. The brand FAQ is 10 g per square metre, so follow the bag in your hand.
Moss is not proof the soil needed lime, and a US square-foot claim is not a UK gram rate. Encap is about £35.06 for 1.13 kg, about £31 per kilogram, and the review texts in the file are from the United States. If a test is actually low, the lime-alone bag with a UK review sample is Westland Lime Soil Conditioner at about £19.98. Do not buy a fast-acting title to kill moss.
The top pick is Westland Lime Soil Conditioner, pack of two, at about £19.98: the brand matches, the item weight is 8 kg, the listing prints 35–70 g per square metre dug in, and amazon.co.uk shows 4.4 from 974 reviews with 50 UK texts in the file. The best value is the Levington Garden Lime 3.5 kg title at about £11.49, about £3.28 per kilogram, the lowest documented price per kilogram of lime alone after the top pick, with the brand field MURIEL BARGAINS and no review line. Encap and Jolly Gardner name lawn grass with US area figures, Topline is lime plus Epsom salt, and two other titles disagree with the seller name or the kilogram line. None of these scores is a laboratory test, and neither badge is a soil test.
Levington Garden Lime 3.5 kg
Lowest documented price per kilogram of lime alone after the top pick, about £3.28 per kilogram at about £11.49.
