The best Plant bags, compared.
Top pick: Mactoou (5 × 3 gallon) – Five non-woven bags at about £11.86, drainage field Yes, rank 5 in Plant Grow Bags, 4.6 from 2,607 reviews. The star line also covers other gallon sizes on that listing. Best value: LATERN (6 × 5 gallon) – Six 5 gallon bags at about £11.99, 4.6 from 920 reviews, with bullets and the dimension field both about 30 cm by 25 cm. Updated October 2026.
A plant bag is an empty soft container you fill with compost. In a UK garden or on a patio you use one when there is no bed, for potatoes, tomatoes, herbs or seedlings. Shoppers also say grow bag for a ready-filled sack of compost. That sack is a different product. These bags arrive empty: a non-woven fabric pot, a polyethylene potato sack, or a thin nursery sleeve. A suitable bag matches the crop in centimetres and litres, not a gallon figure alone. Where both are printed, the litres sit near the US gallon, about 3.8 litres, not the imperial gallon. Potatoes need a container at least 30 cm wide and deep. One tomato plant needs about 30–45 cm across. Fabric lets water through the wall. A plastic sack needs holes you can see. Handles suit an empty bag, and a wet bag is too heavy to lift. Compost is not in the box unless the listing says so. How to separate fabric, a flap sack and a nursery sleeve is set out in the [plant bag buying guide](/hub/plant-accessories/plant-bag/sub/plant-bag-buying-guide).

Personal buying guide
Question 1 of 2
Which container do you need?
Mactoou (5 × 3 gallon) is the top pick. The amazon.co.uk listing is about £11.86, non-woven fabric, drainage field Yes, rank 5 in Plant Grow Bags, and 4.6 from 2,607 reviews. The title size is 3 gallon. The capacity field is 12 litres, and the dimension field is 25.5 × 25.5 × 24.5 cm. Reviews on the same listing also discuss larger gallon sizes, so the star line is the listing’s, not a 3 gallon-only count. Some buyers found the bags smaller than expected, and one review already saw loose threads.
Pros
Cons
Best for: You want a small black fabric bag with a long public review trail.
Less suitable: You need a measured 30 cm potato bag, or a size the reviews do not mix up.
Specifications
Common questions
What size is this pack?
The size field is a 5-pack of 3 gallon bags. The capacity field is 12 litres, and the dimension field is 25.5 × 25.5 × 24.5 cm. Reviews on the listing also talk about 5, 7 and 10 gallon sizes.
Do they have drainage?
The listing field Has Drainage is Yes. The bullets describe a breathable non-woven fabric.
Can they be used for herbs?
A UK review in the listing moved mint and rosemary into these bags. The bullets list potatoes, tomatoes, garlic, onions and beans.
LATERN (6 × 5 gallon) is the best value at about £11.99, 4.6 from 920 reviews, rank 22 in Plant Grow Bags. Diameter and height agree at 30 cm by 25 cm, 5 gallons (17.7 litres), unlike several other listings here. Included components list handles and a flap. UK reviews use the handles to move bags of compost and say a full bag is heavy enough to drag. One review received five bags rather than six. The material field says nylon and the bullets say 300G non-woven. The usage field says indoor while the bullets mention a balcony.
Pros
Cons
Best for: You want a 5 gallon fabric bag whose centimetres match the title.
Less suitable: You need a documented country of origin, or a single material name.
Specifications
Common questions
Do the handles and a flap come with them?
Included components list handles and a flap. UK reviews use the handles to move bags of compost and say a full bag is heavy enough to drag.
What size is printed?
The bullets and the dimension field both say about 30 cm across and 25 cm high, 5 gallons (17.7 litres).
Is the cloth nylon or non-woven?
The material field says nylon. The bullets say 300G non-woven fabric. Both are printed. They are not the same word.
LITLANDSTAR (7 mixed) is about £13.99 for seven coloured bags, 4.6 from nine ratings, rank 213 in Plant Grow Bags. The bullets list two 5 gallon, two 7 gallon, two 10 gallon and one 15 gallon bag. The mix of sizes is the point of the pack. The dimension field is only 30 × 30 × 25 cm, and the capacity field says 15 gallons, so that single box does not describe four sizes. One review saw compost through the cloth when the bag was used as a cover. Nine ratings is a thin record, and the star line does not replace the top pick.
Pros
Cons
Best for: You want several sizes to pot plants up, and you can accept a short review history.
Less suitable: You want one known size with hundreds of reviews.
Specifications
Common questions
What is in the pack?
The bullets list two 5 gallon bags (yellow), two 7 gallon (blue), two 10 gallon (purple) and one 15 gallon. Colours named are yellow, blue, purple and red.
Can they be used for vegetables?
The bullets list potatoes, tomatoes, carrots, onions, beans and herbs. Written reviews mention potatoes, carrots and sweet peas.
Why is there only one dimension?
The dimension field is 30 × 30 × 25 cm and the capacity field says 15 gallons. That single box does not describe four sizes.
RAM (4 × 7 gallon) is about £9.99 for four green polyethylene bags, 4.5 from 1,491 reviews, rank 2 in Plant Grow Bags. It is not the top pick and not the best value. Reviews like the harvest flap. The dimension field says 45 × 45 × 45 cm. More than one UK review measures about 36 cm high and 36 cm across. The drainage field says No, while reviews mention holes in the base. The bullets say waterproof and UV resistant. Check the bag, and measure it, before you fill it.
Pros
Cons
Best for: You want a cheap flap bag for a few seed potatoes and you will measure it.
Less suitable: You need the printed 45 cm cube, or a porous fabric wall.
Specifications
Common questions
Are these fabric pots?
No. The material field is polyethylene. The bullets say waterproof and UV resistant.
Is there drainage?
The field Has Drainage is No. UK reviews describe holes in the base. Treat that as a conflict, and check the bag before you fill it.
Are they 45 cm?
The dimension field says 45 × 45 × 45 cm. More than one UK review measures about 36 cm high and 36 cm across. One review also flags 14 inches on an image.
WHATWEARS (12 × 5 gallon) is about £19.99 for 12 bags, 30 × 30 × 25 cm, 4.5 from 368 reviews, rank 51 in Plant Grow Bags. The material field says felt and the bullets say non-woven. The bullets also cite sewn handles. Drainage is not a Yes/No field. The indoor/outdoor field says Outdoor. A UK review says the bags are floppy until filled, and that a planted bag was too heavy to move. The mounting-type field says Hanging, which is an odd field for a floor bag.
Pros
Cons
Best for: You want twelve 5 gallon fabric bags and can slide them once they are full.
Less suitable: You need a listed drainage flag, or a harvest flap.
Specifications
Common questions
Can they be used indoors?
The indoor/outdoor field says Outdoor. The bullets do not say indoor.
Do they have handles?
Yes. The bullets say built-in sewn handles. A UK review says a planted bag was too heavy to move.
Do they stand up empty?
A UK review says they are floppy until filled, and the rim can collapse if the bag is not full enough.
OFFCUP (5 × 3 gallon) is the lowest fabric pack price here, about £8.99, 4.4 from 147 reviews, rank 16 in Plant Grow Bags. The bullets say 3 gallons (11 litres) and 25 × 22 cm. Other dimension fields contradict that, and one UK review puts the volume near 9 litres and compares that with 12 litres. Has Drainage is Yes. One review says water pours out of the sides, and another said the bags heated in the sun. A lower pack price does not make this the best value, because the centimetres do not agree.
Pros
Cons
Best for: You want the lowest pack price for small fabric bags and you will judge the litre claim yourself.
Less suitable: You need a 30 cm bag for a cordon tomato.
Specifications
Common questions
Are they fabric?
Yes. The material field is non-woven fabric. The bullets describe reinforced seams and nylon handles.
Are they 11 litres or 12 litres?
The bullets say 3 gallons (11 litres) and the size field says 11 litres. A UK review measured about 9 litres and compared that with 12 litres. The dimension fields also disagree with the 25 × 22 cm bullets.
Does water stay in?
Has Drainage is Yes. One UK review says water pours out of the sides, and another said the bags heated in the sun.
UYVYU (6 × 15 gallon) is about £14.99 for six bags titled 15 gallon, 4.4 from 34 reviews. A long UK review used them for early potatoes and carrots and liked the stitching. Another says they rip easily. The bullets say diameter 30 cm and height 50 cm. The dimension fields say 3 × 10 × 5 cm and 30 × 100 × 50 mm. Those cannot all be the same bag. Has Drainage is Yes. Measure the 50 cm claim on arrival. Thirty-four reviews is a short record.
Pros
Cons
Best for: You want a tall bag and you will measure the 50 cm claim on arrival.
Less suitable: You need a size field that matches the title before you order.
Specifications
Common questions
Can they be used indoors?
The usage field says Indoor, Outdoor.
How tall are they?
The bullets say diameter 30 cm and height 50 cm. The dimension fields say 3 × 10 × 5 cm and 30 × 100 × 50 mm. Those cannot all be the same bag.
Is there drainage?
Has Drainage is Yes. A UK review prefers that to plastic pots with no drain hole.
M METERXITY (50 sleeves) is about £9.49 for 50 polyethylene nursery sleeves, 3.7 from 18 reviews, rank 82 in Plant Grow Bags. Reviews use them to move plants and to pot on. They are not the fabric pots in the rest of this comparison. The bullets give a flat size of 17 cm by 25 cm, a loading width of 10 cm, and a soil fill height of 20 cm. One UK review says a filled bag is about 3.5 to 4 inches across, not the flat width. The bullets say they can be used for several seasons. A review says the plastic was thinner than expected. Flat size and filled size are easy to mix up.
Pros
Cons
Best for: You are potting on seedlings or moving plants.
Less suitable: You want a handled fabric bag for a season of tomatoes or potatoes.
Specifications
Common questions
Are these fabric grow bags?
No. The material is polyethylene. The bullets describe nursery sleeves with small holes, 50 in the pack.
What size are they when filled?
The bullets give a flat size of 17 cm by 25 cm, a loading width of 10 cm, and a soil fill height of 20 cm. One UK review says a filled bag is about 3.5 to 4 inches across, not the flat width.
Can they be reused?
The bullets say they can be used for several seasons. A review says the plastic was thinner than expected.
Eight amazon.co.uk listings are scored from the star rating on a 0–100 scale. That is not a garden trial. The top pick is Mactoou (5 × 3 gallon): 4.6 from 2,607 reviews, drainage field Yes, rank 5 in Plant Grow Bags, about £11.86. Reviews on that listing also discuss other gallon sizes. Best value is LATERN (6 × 5 gallon): about £11.99 for six bags, 4.6 from 920, with the dimension field and the bullets both about 30 cm by 25 cm. RAM is rank 2 and is not badged. The drainage field is No, and reviews dispute the 45 cm size.
Centimetres and litres
30%The gallon on the title is not the size. Points follow whether centimetres and litres agree across the bullets and the dimension fields, and whether that size fits the crop. Where both are printed, the litres sit near the US gallon, about 3.8 litres, not the imperial gallon. A field that contradicts the bullets is marked down.
Drainage and material
25%Fabric is porous. A drainage field of Yes is readable. A field of No, or no Yes/No field at all, is not the same wall. Polyethylene and a nursery sleeve are different products from a fabric pot. Air pruning is trade language, not a measurement of these listings.
Reviews for this size
25%amazon.co.uk stars count only with the review count on that listing. A long trail that also discusses other gallon sizes is the listing’s score, not proof of one size. A handful of ratings is a thin sample. Rank in Plant Grow Bags is recorded. It is not a garden trial.
Pack price after the size fits
20%Shelf price is compared after the type and the centimetres fit. Best value is the 5 gallon pack whose 30 cm by 25 cm line agrees, not the lowest price in the comparison. A 50-pack of nursery sleeves is a different job from a fabric pot.
Start with the type, then the centimetres, then the drainage, then the price. An empty fabric pot, a polyethylene potato sack and a thin nursery sleeve do not do the same job. A ready-filled compost sack is a fourth object, and it is not in this comparison. Shelf prices in this capture run from about £8.99 to about £19.99. The top pick is the Mactoou 3 gallon five-pack. The best value is the LATERN 5 gallon six-pack, because 30 cm by 25 cm agrees across the listing.
A plant bag, in the sense a UK shopper meets on amazon.co.uk, is an empty soft container you fill with compost. Three kinds sit in this comparison. A fabric pot is non-woven or felt, usually with handles, and the wall is porous. A polyethylene potato bag is a thicker sack, sometimes with a side flap for checking tubers. A nursery sleeve is a thin polyethylene tube with holes, sold in a large pack, for moving seedlings and potting on.
A US gallon on these listings is about 3.8 litres where litres are printed, not an imperial gallon. RAM’s 45 cm field is disputed by reviews around 36 cm. UYVYU’s bullets say 30 cm by 50 cm while other dimension fields are a few centimetres. If the lines disagree, the bag has not passed the size check.
These are empty containers. A ready-filled grow bag, the sack you slit and plant into, is a different product. A waste sack or a frost cover is a different product again. Fabric, a flap sack and a nursery sleeve should not share one score.
Handles suit an empty bag. UK reviews of filled 5 gallon fabric bags say they are too heavy to lift. Underfilling a floppy rim lets it collapse. There is no safe load figure for a balcony or a roof in these listings.
Choose the object before the brand. A fabric pot, a polyethylene potato sack and a nursery sleeve are three products that share a search word. Fabric walls are porous, so water leaves through the sides. That is not a measured air-pruning result. A drainage field of Yes is readable. RAM’s field says No, while reviews mention holes, so you check the bag before you fill it. WHATWEARS has no Yes/No drainage field.
Stars count only with the review count, and only for the listing as published. Mactoou is 4.6 from 2,607 and rank 5 in Plant Grow Bags, and reviews on that listing also discuss other gallon sizes. LATERN is 4.6 from 920, with a listed flap, and one review received five bags rather than six. RAM is 4.5 from 1,491 and rank 2, and it is not badged, because the 45 cm line and the drainage field conflict with the reviews. LITLANDSTAR is 4.6 from nine ratings.
Three typical situations, each with a recommendation from this comparison.
You want a small black fabric bag and a long public review trail, and you can water often. Mactoou (5 × 3 gallon) at about £11.86 is the top pick: five non-woven bags, stated 3 gallon (12 litres), 25.5 × 25.5 × 24.5 cm, drainage field Yes, 4.6 from 2,607 reviews. Reviews on that listing also discuss other gallon sizes. Skip it if you need a measured 30 cm potato bag.
You want a fabric pot near the 30 cm line, and you will water it often. LATERN (6 × 5 gallon) at about £11.99 is the best value: six bags, bullets and the dimension field both about 30 cm by 25 cm, 5 gallons (17.7 litres), 4.6 from 920 reviews, with handles and a flap. One pack arrived one bag short. Skip it if you need a single material name.
You want a flap to check tubers, and you will measure the bag before you trust the title. RAM (4 × 7 gallon) at about £9.99 is four green polyethylene bags, 4.5 from 1,491 reviews, rank 2 in Plant Grow Bags. Reviews like the side window. The 45 cm field is disputed, and the drainage field says No. Skip it if you need a porous fabric wall or the printed 45 cm cube.
The top pick is Mactoou (5 × 3 gallon), at about £11.86. It is five non-woven bags, stated 3 gallon (12 litres), with dimensions 25.5 × 25.5 × 24.5 cm, handles, and a drainage field of Yes. amazon.co.uk shows 4.6 from 2,607 reviews, and the listing is rank 5 in Plant Grow Bags. Reviews on that listing also discuss other gallon sizes, so the star line is not a 3 gallon-only count. LITLANDSTAR is also 4.6, from nine reviews, which is too thin a sample to replace this pack. The best value is LATERN (6 × 5 gallon), at about £11.99 for six bags. Bullets and the dimension field both say about 30 cm by 25 cm, 5 gallons (17.7 litres), with 4.6 from 920 reviews, handles and a flap. One review received five bags rather than six, and the material field says nylon while the bullets say 300G non-woven. None of these scores is a garden trial.
