The best bark mulches, compared.
Top pick: Indigo composted bark 60 L Best value: Laeto bark chippings 60 L – Lowest shelf price at about £15.19, 60 litres that agree, and 4.3 from 595 reviews. Updated October 2026.
Bark mulch is chipped or composted tree bark, sold in the UK by the litre for beds and borders. On amazon.co.uk the usual purchase is one 50-70 litre bag, and you have to tell it apart from wood chip, coir discs and glue. Judge a sack by the grade, by whether the litre claim matches the details, and by a clean fill without plastic, glass or treated timber. For a border, the Royal Horticultural Society says at least 5 cm and ideally 7.5 cm on moist, weeded soil, about 10 cm clear of woody stems. Grade and litre checks are in the [bark mulch buying guide](/hub/fertiliser-soil-and-bark-mulch/bark-mulch/sub/bark-mulch-buying-guide). None of these bags is scored as EN 1177 play bark. It is not wood chip, a coir disc, fabric, or glue.

Question 1 of 2
What are you covering?
Indigo composted bark is a 60 litre bag sold as a mulch and a soil conditioner for beds, borders, and containers, at £15.69 on 19 October 2026. The title and the volume field both say 60 litres. The unit-count field is 28,000 grams, and no separate kilogram weight is listed, so the mass of the sack is still unclear. The amazon.co.uk line is 5.0 from one review, and that review says plants love it and names no fault. One rating is not a quality finding. The bullets claim moisture retention and soil improvement, and they do not claim weed suppression or a play surface. There is no particle size. Until more UK buyers describe the texture, this is a grade you can read on the title and a bag you cannot judge from the stars.
Pros
Cons
Best for: A buyer who wants composted bark for beds or containers and will judge the sack on arrival.
Less suitable: A border that needs a chip that still looks like bark next year, or anyone reading 5.0 as a record.
Specifications
Common questions
Is this chipped decorative bark?
No. The title and style name say composted bark, sold as a mulch and a soil conditioner for beds, borders and containers.
Do the litres match?
The title and the volume field both say 60 litres. The unit-count field is 28,000 grams. No separate kilogram weight is given.
How many reviews support the five-star line?
The listing line is 5.0 out of 5 from 1 review. That review says plants love it and does not describe a fault.
The indigo 70 litre bag is chipped border bark whose title, unit count, and volume field all say 70 litres, at £15.99 on 19 October 2026, about 23p a litre. On amazon.co.uk it sits at 4.6 from 86 reviews. Most of the 18 review texts in the file praise weed cover, colour, and how readily the chips go down on flower beds, borders, and paths. One reviewer found the sack full of large wood and twigs rather than even chips. No particle size is printed and no weight is given, so you cannot check it against a 15-35 mm border range before it arrives. The bullets claim weed suppression and moisture retention, and they make no play-area claim. A 4.6 from 86 is a usable sample, and it is still a thinner file than Laeto's 595.
Pros
Cons
Best for: Beds and borders where you want chipped bark and a litre count that agrees with itself.
Less suitable: Clay you want to improve, pots that need fines, or a playground.
Specifications
Common questions
How much is in the bag?
The title, the 70,000 millilitre unit count and the volume field all say 70 litres. No weight is given.
Does the listing say it stops weeds?
Yes. The bullets call it a weed suppressant and say it helps soil hold moisture.
Is it stated as suitable for a vegetable garden?
The listing does not answer that question. The bullets name flower beds, borders and pathways.
Melcourt composted fine bark is the soil-improvement bag in this set, listed at £15.95 with 4.5 from 370 amazon.co.uk reviews. Reviewers repeatedly describe a fine, dark, heavy product used on clay, in pots, and for bonsai, and one says it behaves like compost rather than chippings. The listing weight is 20 kg, and reviews also call the sack very heavy. The title says 50 litres and RHS endorsed, while a volume field on the same page says 40 litres, and this comparison has not checked an RHS licence number. One July 2026 review reports rock, brick, glass, and plastic in the bag, and others mention burst sacks. The style name says nutrient-rich and moisture-retaining. There is no particle size on this listing and no play claim.
Pros
Cons
Best for: Clay beds and pots, if you can lift 20 kg and you tip the bag out where you can see rubbish.
Less suitable: A decorative path, a play area, or a buyer who needs a single litre figure.
Specifications
Common questions
How many litres does the listing claim?
The title says 50 litres and the unit count is 50,000 millilitres. A volume field on the same listing says 40 litres. Both figures are recorded. Neither was measured.
Is the RHS endorsement verified?
The title says RHS endorsed. The listing does not include a licence number, and this page has not checked one.
How heavy is the bag?
The listing says 20 kg. Reviews also describe the sack as very heavy.
The Laeto 60 litre sack is decorative bark chippings at £15.19, the lowest shelf price in this set on 19 October 2026, with 4.3 from 595 amazon.co.uk reviews. The title and the volume field both say 60 litres, which works out at about 25p a litre, and the listed weight is 10.9 kg. Reviewers often praise the colour, the smell, and the cover around trees and shrubs. The same file keeps returning to wet, heavy sacks, chips that do not match the photograph, and pieces of plastic. At least one buyer described the contents as wet logging waste rather than ornamental bark. A bullet says the bag is suitable as play bark, and the listing gives no particle range and no EN 1177 certificate. A separate unit-count field is stored as 60,000 grams, which does not sit with the 10.9 kg weight.
Pros
Cons
Best for: A border or a path where you want decorative chips and you will open the bag before you spread it.
Less suitable: A play surface, or a buyer who needs a printed millimetre grade.
Specifications
Common questions
Is the stated volume consistent?
The title and the volume field both say 60 litres. A separate unit-count field is stored as 60,000 grams, and the listed weight is 10.9 kg.
Does the listing claim it suppresses weeds?
Yes. The bullets say weed suppression and moisture retention for beds, borders and pathways.
Is it certified play bark?
A bullet says it is suitable as play bark. The listing has no particle range and no EN 1177 certificate.
The Laeto sack is an organic compost mulch and soil improver that contains composted bark, at £18.99 on 19 October 2026, the highest shelf price in this set. The title says 50 litres, the volume field says 60 litres, and the unit count is stored as 50,000 grams. Across 63 reviews at 4.3, more than one buyer says the bag was far smaller than the title, and one says they weighed it at about 5 or 6 litres. Smell splits the file: some call it strong, and one says it did not smell. One reviewer says bushes and dahlias rotted and blames the bag, which is a single allegation and not a cause this comparison can show. The bullets name vegetables, flowers, fruits, roses, trees, and shrubs, and they claim weed and moisture effects. If you wanted straight bark chippings, this listing is a different product.
Pros
Cons
Best for: A soil improver only if you check the sack on the day it arrives and you can return a short bag.
Less suitable: Decorative chippings, a play surface, or anyone who needs the litre count to match.
Specifications
Common questions
Is this a bag of bark chippings?
No. The title is an organic compost mulch and soil improver with composted bark. The item type is mulch. Bullets describe fine bark particles, not a chip size.
Which volume does the listing state?
The title says 50 litres. The volume field says 60 litres. The unit count is 50,000 grams. Reviews in the file say the bag was much smaller, including one weighed at about 5 or 6 litres.
Does the listing name vegetable beds?
Yes. The bullets and the item highlight name vegetables, as well as flowers, fruits, roses, trees and shrubs.
Five amazon.co.uk listings were scored from the stored pages and the UK review notes already on file. Shelf date 19 October 2026. This is not a garden trial and not a sieve test. A weed, moisture, soil or play line on a listing is a claim. An RHS line in a title is a claim. None of these bags is scored as EN 1177 play bark. The highest score is the top pick. The best value is the lowest believable shelf price among bags whose litres agree, with a large review count, and it is not the top pick. The weights below sum to 100.
Amazon evidence
35%Star rating and rating count on amazon.co.uk. A 5.0 from one rating is not scored as a sample. A large count scores when the written themes belong to that ASIN.
Listing fit
25%A grade you can name, litres that agree between the title and the volume field, and a weight when the sack is heavy. A missing particle size scores down. A play bullet with no certificate scores down. A title that disagrees with the volume field scores down further.
Review outcome
25%United Kingdom review notes that describe colour, weed cover, clay or pots score up. Plastic, a short bag, glass or a sack of twigs scores down. One allegation that plants rotted is recorded and is not scored as a proven cause.
Value
15%Shelf price in GBP against litres you can believe. A low bag price does not score here when reviewers say the sack was a fraction of the title.
Buy the grade before you buy the star line. Chippings, composted fines and play bark are not one list. Prices below are amazon.co.uk shelf prices on 19 October 2026. This is not a laboratory test and not a sieve test.
Bark mulch is chipped or composted tree bark, sold in the UK by the litre for beds and borders. It is not wood chip, a coir disc, fabric, or glue. On amazon.co.uk the usual purchase is one 50-70 litre bag. You judge it by the grade, by whether the litre claim matches the details, and by a clean fill without plastic, glass, or treated timber. Ornamental chippings stay on the surface. Ornamental ranges are often about 5-35 mm, and border grades about 15-35 mm.
The RHS says about 70 litres covers about one square metre. A 60 litre bag is about 1.2 square metres at 50 mm before settlement. One sack will not cover a long border at 5-7.5 cm.
Melcourt says 50 litres in the title and 40 litres in a volume field. Laeto compost mulch says 50 litres in the title and 60 litres in a volume field, and reviewers say the bag was much smaller. Do not quote one litre figure for either.
Laeto chippings says suitable as play bark and gives no particle range and no EN 1177 certificate. Play depths in BS EN 1176-1:2017 are 200 mm or 300 mm plus another 100 mm, not the garden 5 cm figure.
Buy bark, and name the grade before you compare the star line. Reject coir mats, fabric rings, gravel glue, and wood chippings. Screened chippings cover the surface and last longer. Ornamental ranges are often about 5-35 mm, and border grades about 15-35 mm. Composted fines are dark and crumbly and suit clay, pots, and the top of a bed. Play-grade bark is a third product. In BS EN 1176-1:2017 Table 4 it is 20-80 mm, and a garden sack with a play bullet is not that product.
On 19 October 2026 these five bags cost about £15.19 to £18.99. Ordinary 50-70 litre bags in the wider aisle often sat around £14-£16. Named grades often sat around £17-£20, and some packs and a 100 litre bag sat around £20-£25, with one bag at £24.99. Best Sellers in Mulches mixes bark with straw and soil. Quote pence per litre only when the litres agree: about 23p for Indigo chipped bark and about 25p for Laeto chippings.
Three typical situations, each with a recommendation from this comparison.
You want screened chippings and a litre count that agrees with itself. Indigo chipped bark 70 L is the top pick at about £15.99, with 4.6 from 86 reviews. The title, the unit count and the volume field all say 70 litres. No particle size is printed, and one review describes large wood and twigs.
Composted fines are the grade reviewers use on clay, in pots and for bonsai. Melcourt composted fine bark is about £15.95, with 4.5 from 370 reviews, and the listing weight is 20 kg. The title says 50 litres and a volume field says 40 litres. Tip the bag out where you can see rubbish.
Laeto bark chippings 60 L is the best value at about £15.19, the lowest shelf price in this set, with 4.3 from 595 reviews and 60 litres that agree. Reviewers mention colour and cover, and also plastic, wet sacks and chips that do not match the photograph. Open the bag before you spread it.
Indigo chipped bark 70 L is the top pick at about £15.99, with 70 litres that agree and 4.6 from 86 reviews, about 23p a litre. Laeto bark chippings 60 L is the best value at about £15.19, with 4.3 from 595 reviews, if you open the sack before you spread it. Melcourt composted fine bark is the clay and pot bag, and its title says 50 litres while a volume field says 40 litres. None of these bags is an EN 1177 play surface, and a 5.0 from one review is not a quality finding.
