How to use a tree watering bag: fit, shake, refill
Updated: October 2026
The sleeve or ring is out of the box and the tree is already in the ground. How to use a tree watering bag comes down to four jobs: fit it, shake the outlets, fill it where it stands, and take it off before frost. One fill lasts hours, not a week away.

Fit the bag or the ring
Close the zip around a clear stem, or lay a ring flat on the soil. baumbad.co.uk’s instructions start with the zip. A TUAKIMCE listing says wrap, zip, fill, and lift the handles, with no tools. The handles seat the sleeve. They are not for carrying a full bag. A Kukyller-style ring is laid flat, filled through the lid, and closed. A hose is not in the box. Match the trunk before you force the zip. The tree watering bag buying guide separates 8–30 cm girth from a diameter in inches. If the stem is thicker than one sleeve, baumbad’s FAQ steps you to a second bag, then a third or a fourth. A ring belongs on level soil, under branches a tall sleeve cannot pass.
Shake, then fill
Put in about 5–10 litres, shake the bag by the loops so the two openings at the bottom folds drop clear, then fill. That is the order on baumbad.co.uk’s instruction page. Another baumbad page leans towards a third of the bag, so follow the sheet in your box. UK reviews describe a sleeve that stays slumped until it is shaken, which traps water above the holes. Fill the rest where the tree is. A full 75 litre sleeve holds about 75 kg of water. Do not lift it. On that instructions page, 75 litres is associated with about nine hours and 100 litres with about 12 hours. Other listings often claim five to eight hours.
When the water will not come out
Shake the two openings again before you change the bag. baumbad.co.uk’s FAQ names dirty water and mowers as the usual cause. A ring on a slope can hold water on the high side, so level it or move it onto flatter soil. If a sleeve is twisted, open the zip, lay the folds, and close it again. Do not cut extra holes. One UK review of B07VMVMGYN describes a buyer piercing the bag. That comment is a report, not a method. Extra holes change the release time and become a tear. If the holes are split rather than blocked, repair or replace the bag, and keep the sleeve out of the strimmer line.
Mice, mowers, and winter
Mice, martens, and foxes bite bags in a drought, according to baumbad.co.uk’s FAQ. A water bowl at ground level is their suggested deterrent, not a repair. Keep mowers off the drip folds. Take the bag off before frost, empty it, dry it, and store it at about 5–20°C. Frost makes the material brittle, and a damp sleeve left on the trunk can leave mould on the bark. Barcham says do not hang the bag to store and do not add chemicals. A Kukyller listing allows a nutrient solution. Follow the sheet for the product you own. Weekly litres are on the newly planted trees guide.
Common questions
How do I put the sleeve on?
Zip it around a clear stem, or lay a ring and close the lid after filling. baumbad.co.uk starts with the zip. A TUAKIMCE-style list is wrap, zip, fill, and lift the handles, with no tools. The handles seat the bag. They are not for carrying it full.
Why do I shake it before it is full?
A first pour of about 5–10 litres lets you shake the loops so the two bottom openings drop clear. A slumped sleeve traps water above the holes. Another baumbad page leans towards a third of the bag, so follow the sheet in your box, then fill the rest where the tree is.
What if no water comes out?
Shake the two openings and clear dirt or grass. baumbad.co.uk names mowers and dirty water as the usual cause. A ring on a slope can hold water off the outlets, so reseat it on flatter ground. If the sleeve is twisted, refit the zip. If the holes are already split, repair or replace the bag.
Can I pierce extra holes?
The instructions say to shake the two openings clear. One UK review of B07VMVMGYN describes a buyer who pierced the bag. That report is not a method. Extra holes shorten the release and turn into tears. A full 75 litre sleeve is about 75 kg, so fill it at the tree.
How do I fit two bags on a thick trunk?
Zip a second sleeve beside the first once the girth is past a single bag. baumbad.co.uk’s FAQ steps from one bag to two, three, and four as circumference grows. Each sleeve still needs the small first pour and the shake. Fill both where they hang. Do not lift a full bag into place.
What do I do about mice?
baumbad.co.uk names mice, martens, and foxes biting bags in dry weather, and suggests a ground-level water bowl. The bowl may draw animals off the plastic. It does not mend a hole. Empty a bitten bag and repair or replace it. Keep mowers off the drip folds so a blade does not add another leak.
When do I take it off for winter?
Empty and dry it before frost, then store it at about 5–20°C. baumbad.co.uk says frost makes the material brittle and a bag left on the trunk can lead to mould. Barcham says do not hang it or add chemicals. Follow the sheet for the bag you own.
