Tree watering bag comparison 2026
The best tree watering bags, compared.
Top pick: baumbad 75 litre – 4.3 from 1,603 ratings, with 75 litres, up to 9 hours, and 8–30 cm girth on the listing. Best value: baumbad 75 litre – About £12.97, the lowest price among these listings with at least 100 ratings. Updated October 2026.
A tree watering bag is a PVC sleeve or ring that drips for several hours from small openings. You use one when a watering can is awkward for a newly planted tree. Check litres or the printed unit, a girth or diameter, a stated empty time, and a real star count. Where hours are printed they sit at about 5–9 hours, then you refill if the soil is dry. One fill will not cover a week away. A [water butt](/hub/garden-watering/water-butt) is not a hosepipe. Water leaves through small openings and the bag is empty in hours, not in a week. The bag does not create an exemption from that restriction. Litres come first when the label uses litres.

The best tree watering bags in detail
Our view
The baumbad 75 litre sleeve is £12.97, with 4.3 from 1,603 amazon.co.uk ratings, the only listing in this set with its own star line. The listing gives 8–30 cm trunk circumference for one bag, a hose inlet up to 10 cm, and a release of up to 9 hours. The bullet weight is 740 g and the specification block says 694 g. UK reviews praise slow watering in a drought and a strong zip. They also report mice chewing holes, a bag that slumps until it is shaken, and at least one buyer who had to pierce the drain holes.
Pros
- About £12.97, the lowest price among listings with at least 100 ratings
- 4.3 from 1,603 ratings
- Listing: 75 litres, up to 9 hours, 8–30 cm girth
- UK reviews describe a strong zip and slow watering of new trees
Cons
- Bullet weight 740 g and specification weight 694 g
- UK reviews: rodent holes, a slump that traps water, and holes the buyer had to pierce
- One UK review was charged import duty
- Some reviews say the bag empties far faster than 9 hours once it is punctured
Best for: One garden tree inside the listed 8–30 cm girth, refilled after the stated hours
Less suitable: A holiday of several days on one fill, or a site where rodents have already chewed a bag

Common questions
What trunk size does the listing give?
One bag is listed for a trunk circumference of 8–30 cm. The same listing says two or more bags for larger trees.
How long does the listing say one fill lasts?
The bullets say up to 9 hours from one fill of 75 litres. Reviews also describe empties that were much shorter after a puncture.
Does the box include a hose?
The power line says no plug is included. A hose is not in the included-components text. The inlet is listed for hoses up to 10 cm across.
Our view
This is one 100 litre green PVC sleeve at £16.99. The bullets say up to 9 hours. The specification block gives 889 g and flat dimensions of 113 x 89 x 2 cm, and it does not state a girth. The Customer Reviews line is 4.1 from 576, the same line as the five-pack listing, so those two counts are not separate samples. Reviews on this listing say a 100 litre bag can stand too high where branches start low, and that outlets can clog.
Pros
- 100 litres in one sleeve at about £16.99
- Listing release of up to 9 hours
- Reviews describe a thick bag and a zip that joins a second bag
- Green PVC, country of origin China
Cons
- No girth on this listing
- 4.1 from 576 is shared with the five-pack listing
- Reviews say the 100 litre bag is tall for low branches
- The same review text reports clogged outlets and water left in the bag
Best for: A trunk tall enough for a 100 litre sleeve, where one larger fill is the point
Less suitable: A young tree with low branches, or a buyer who needs a girth printed on this listing

Common questions
Does this listing state a trunk girth?
No. Capacity is 100 litres and the release line says up to 9 hours. A review says this taller bag can be too high where branches start low.
Is the 4.1 from 576 a separate sample from the five-pack?
No. The Customer Reviews line matches the five-pack listing, and many review bodies are the same. Treat it as one shared line.
What is in the box?
The listing is one 100 litre bag. A hose and a plug are not included.
Our view
The title is five 75 litre baumbad sleeves at £56.94. The box-contents bullet names a single bag and a weight of 3,700 g, so the pack count is not consistent on the listing. Girth is 8–30 cm for one bag and the release line is up to 9 hours. The star line is 4.1 from 576, shared with the 100 litre listing. UK reviews like the slow soak on new trees and also report German instructions, uneven drip holes, and valves that failed open.
Pros
- Title pack of five 75 litre sleeves
- Same girth and 9-hour line as the single 75 litre listing
- UK reviews: useful in a narrow border and during a hosepipe restriction
- A reviewer was offered a patch kit for a jetting bag
Cons
- Title says five bags; the contents bullet says one
- About £56.94, not a cheaper single
- 4.1 from 576 is shared with the 100 litre listing
- UK reviews: German instructions, uneven holes, and failed valves
Best for: Several young trees if the title pack of five is what arrives
Less suitable: One tree, or a buyer who needs the paper instructions in English

Our view
Kukyller lists two black PVC rings at £12.79, 10 gallons each, with a stated drip of 5–7 hours and a refill note of once or twice a week. Setup is lay the ring, open the lid, fill, and close the lid.

How we compared
Scores use the seven amazon.co.uk listings read on 15 October 2026. No bag was laboratory tested. Price decides the best value badge and does not change the score. A missing Customer Reviews line is an amazon rating of 0 and a count of 0. The 4.1 from 576 line is shared by the 100 litre sleeve and the five-pack. It is one sample, and both rows use it.

Tree watering bag buying guide
Match litres, the unit on the label, and the trunk measurement before you compare price. Hours tell you when to refill. A star line you can cite matters more than a low shelf price with no reviews.
What is a tree watering bag?
A tree watering bag is a PVC reservoir. A sleeve zips around the trunk. A ring lies on the soil. Water leaves through small openings and the bag is empty in hours, not in a week. You buy one to keep a newly planted tree moist when a watering can is impractical, including while a hosepipe restriction is in force. The bag does not create an exemption from that restriction. All seven listings here are PVC, and none includes a mains plug. Litres come first when the label uses litres.
Best for
- One garden tree inside an 8–30 cm girth, refilled after the stated hours
- A short stem where a ring is easier than a tall sleeve
Not ideal for
- A week away on one fill
- A hosepipe ban, which a bag does not lift
Mistakes to avoid
- 1
Reading diameter as girth
baumbad prints circumference, 8–30 cm. TUAKIMCE prints diameter, 2–4 inches. 30 cm girth is about 9.5 cm across. Mixing the two sends the wrong bag.
- 2
Treating gallons as 75 litres
The gallon listings do not say US or imperial gallons. This page does not convert them. A 20 gallon label is not a measured 75 litre bag.
- 3
Expecting one fill to last a holiday
Stated release in this set is about 5–9 hours where hours are printed. Someone refills if the soil is dry. Skipping the shake can leave water trapped in the bag.
What to weigh up
Litres and the unit on the label
HighIf water is due, the volume is the first check. The RHS figure for a newly planted tree is 40–60 litres in a dry week, four to six 10 litre cans, for the establishment years. A second RHS count uses 9 litre cans, 36–54 litres, for two years. New urban trees are put at 50 litres a week from May to August for three years. Fill a bag if one is fitted. Established trees that were well chosen usually need no routine water except in a long dry spell.
Trunk fit and stated hours
HighGirth and diameter are different measurements. One baumbad bag is listed for 8–30 cm circumference, and the same listing says two or more bags for a larger trunk. 30 cm around is about 9.5 cm across. TUAKIMCE prints 2–4 inches diameter for one bag, 4–8 inches when two bags are zipped together, and at least 25 inches of bare trunk. The 100 litre baumbad listing prints no girth. Ieron and Kukyller print none either. The Yosoo title includes 60 cm and does not define it.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Several young standards
You want more than one sleeve. The baumbad title says five 75 litre bags at about £56.94, with the same girth and 9-hour line. The contents bullet on that listing says one bag, so check what arrives.
A street-tree volunteer
New urban trees are quoted at 50 litres a week from May to August for three years. Do not fit a private bag on a council tree unless you have asked. If a bag is already fitted and you are allowed to fill it, the 75 litre sleeve is the listing with litres and hours.
Common questions about tree watering bags
Which tree watering bag is the top pick?
The top pick is the baumbad 75 litre sleeve for one trunk inside the listed 8–30 cm girth. On amazon.co.uk it was about £12.97, with 4.3 from 1,603 ratings. The listing states 75 litres and a release of up to 9 hours. It is also the best value, the lowest price among these listings with at least 100 ratings. UK reviews report rodent holes, a slump until the bag is shaken, and drain holes a buyer had to pierce. Skip it if one fill must last several days.
How much does a tree watering bag cost on amazon.co.uk?
Shelf prices on 15 October 2026, as a rule of thumb from these seven listings. Entry is about £10–£13: the Yosoo ring at about £9.69, the Kukyller two-pack at about £12.79, and the baumbad 75 litre sleeve at about £12.97. Mid is about £17–£28: the 100 litre sleeve at about £16.99 and the Ieron two-pack at about £27.99. The two five-packs sit at about £55–£57, the TUAKIMCE at about £54.99 and the baumbad title pack at about £56.94. A five-pack is not a better single bag.
What should you check before you buy a tree watering bag?
Read litres first when the label uses litres. The RHS quotes 40–60 litres in a dry week for a newly planted tree. New urban trees are put at 50 litres a week from May to August for three years. Then read the unit. A gallon label is not a measured litre figure, and this page does not convert it. Check girth or diameter, plus a stated empty time and a real star count. The tree watering bag buying guide sets those checks out before the table.
Does a tree watering bag exempt you from a hosepipe ban?
No. Section 76 of the Water Industry Act 1991 lets a company in England and Wales restrict hosepipe uses, including garden watering, if a serious shortage is expected. The notice names the start and the area. Scotland and Northern Ireland use their own notice. An exemption for young trees can be removed. From 9 October 2026, South East Water in Sussex barred hosepipes for trees. A passive bag does not make a hosepipe legal. Hosepipe ban: what you can still water covers the wider rules.
Should you buy a 75 litre or a 100 litre sleeve?
Buy the 75 litre baumbad sleeve for a trunk inside 8–30 cm girth. It was about £12.97, with 4.3 from 1,603 ratings, 75 litres, and a release of up to 9 hours. Buy the 100 litre sleeve, about £16.99, when the trunk is tall enough for a larger fill. That listing says up to 9 hours and prints no girth. Reviews say it can stand too high where branches start low. Its 4.1 from 576 is the same line as the five-pack, not a second sample.
Is a sleeve or a ring the better fit?
A sleeve zips around the trunk. A ring lies on the soil and suits a short stem. Rings empty badly on a slope. The Yosoo is one green 10 gallon ring at about £9.69. The 60 cm in the title is not defined as diameter or girth, and it states no hours. The Kukyller is two black 10 gallon rings at about £12.79, with a stated drip of 5–7 hours and no girth. All seven listings are PVC, and none includes a mains plug.
How often should you refill a tree watering bag?
Refill when the soil is dry, not on a calendar alone. Listings that state a time give about 5–9 hours for one fill: TUAKIMCE 5–8 hours, Kukyller 5–7 hours, and baumbad up to 9 hours. Ieron and Yosoo state no hours. A person refills after that if a trowel shows dry soil. One fill will not cover a holiday. Soak to 20–30 cm. Overwatering rots roots. Established, well-chosen trees usually need no routine water except in a long dry spell. Keep a 1.2 m weed-free circle for three years.
What goes wrong with a tree watering bag?
UK reviews on the 75 litre sleeve report mice chewing holes, a bag that slumps until it is shaken, and drain holes a buyer had to pierce. Once punctured, some reviews say it empties far faster than 9 hours. Five-pack reviews report uneven holes, valves that failed open, and paper instructions in German. The 100 litre reviews report clogged outlets and water left in the bag. Do not cut extra holes. Empty the bag before frost, keep mowers off it, and shake the two openings.
Our verdict
The top pick and the best value are the same listing: the baumbad 75 litre sleeve at about £12.97. It leads on 4.3 from 1,603 ratings, with 75 litres, up to 9 hours, and an 8–30 cm girth on the amazon.co.uk page. Price did not change the score. The value rule is the lowest shelf price among listings with at least 100 ratings. The 100 litre sleeve is next on score, at about £16.99, and that listing does not state a girth. The five-pack shares the 4.1 from 576 line and disagrees with itself on whether five bags or one bag arrive.
