Bonsai cut paste
Updated: October 2026
You have taken a small branch off a bonsai on the bench, the cut is on the front of the tree, and a 300 g garden bottle would swamp it. Bonsai cut paste, in this amazon.co.uk set, means the 100 g Kiyonal tube rather than a pruning seal or a bright green tub. It is the matching tool for that small visible wound. It is not a declaration that it is the best paste in Britain, and it does not cancel the garden rule that ordinary cuts often stay open. The row sits on the [tree wax comparison](/hub/trees-and-palms/tree-wax). The Products Compared editorial team wrote this on 16 October 2026 from that listing, from UK bonsai shop pages, and from a club note on wounds. We did not style a tree.

Why a garden bottle is a poor fit
Provanto Arbrex Seal and Heal is a 300 g UK-made gel with a brush cap, captured at £7.80 with 4.5 from 1,172 ratings. Across the first 50 UK reviews, people use it on fruit trees, acers, and damaged bark. They also say it is extremely sticky, that it gets on hands, clothes, hair, and ladders, and that the cap flies off if you squeeze hard. That is a workable mess on a ladder against a plum. It is a poor fit on a shohin or a refined deciduous bonsai, where the wound may be the size of a fingernail and the bark is part of the display. The bottle has no fine nozzle. A thin coat on a large pruning cut is the label's job. A dab on a styled cut wants a tube you can touch to the wood and lift away. Using Arbrex because it is the garden top pick on the best tree wound sealer page imports stickiness and volume you do not need. The Royal Horticultural Society still tells you not to paint ordinary garden cuts, and a bonsai habit is not a licence to coat every acer in the border.
Kiyonal in this comparison
Kiyonal, ASIN B00B32S1KK, is the in-set candidate. Zac's Bonsai sells it as a Japanese cut paste for bonsai wounds. The captured price is £11.99, and the star line is 4.6 from 487 amazon.co.uk ratings, the highest sticker price in this set. The title, the unit count, and the item weight say 100 g. A liquid-volume field also says 0.25 litres. That conflict is already in the technical block. It does not mean the tube holds a quarter of a litre, and it should not change how much you squeeze out. In the first 50 reviews, people praise a little paste on bonsai cuts and a bark-like colour once it has dried. Reviewers talk about one to two days to dry. The instructions on the tube are in Japanese with no English, so you cannot read a dosage or a species list off the pack. Paste sticks to fingers if you do not apply it from the tube or with a tool. Tubes split. Put a small amount on the cut face, about the size of the wound, and do not bury the collar. A flush cut that leaves a cavity is a shaping error paste will not fill. Swindon & District Bonsai describes club practice of using cut paste after branch removal to limit moisture loss. That is practitioner habit, not RHS garden advice, and this page does not claim the paste contains hormones.
Colour that shows on the tree
On a bonsai, the film is part of the picture until it weathers or the callus covers it. Kiyonal's reviews describe a dry colour close to bark. The generic tubs in this set do not. Vividye is a 500 g water-based paste at £10.99, about £2.20 per stated 100 g, with 4.5 from 9 ratings. UK reviews praise brushing and call the film extremely bright green, and one reviewer would not use it on bonsai. That tub can be the volume buy for garden cuts. On a show tree it is the wrong pick, so the best-value slot on the best-of page is not a bonsai recommendation. The three Flintronic listings share 4.2 from 6, and the only UK comment says the colour is a bit garish. The £6.99 tub, the £8.00 tape bundle, and the £9.99 twin pack do not become discreet because one is cheaper. Comioke is listed as white, so a pale patch shows on dark bark, and that listing has only two review bodies against a count of 6. If the colour will shout, skip the tub.
Tub paste you will not find in this table
UK bonsai shops sell a different object, and those tubs are not rows in this comparison. Herons lists a grey cut paste at £22 for 160 g, aimed at branch cuts and especially deciduous trees. A brown evergreen variant is a separate shop page. Bonsai Direct sells a 190 g tub for larger wounds and points smaller cuts toward a Kiyonal-style tube. Those are shop prices, not amazon.co.uk captures, and they do not make Kiyonal the winner of a test we did not run. Use the tube when the cut is small: nozzle or tool, not a finger loaded with paste. A shop tub, outside this table, suits a wound large enough that a 100 g tube becomes fiddly. Do not empty Arbrex onto the tree because the bottle is cheaper per gram. The stickiness reviewers describe will sit in bark you spent years refining. For this tube, the method is a dab and the cap back on.
Common questions
Is Kiyonal the tube for small cuts?
Inside this comparison, yes. Kiyonal is the 100 g Japanese tube sold by Zac's Bonsai, at £11.99 with 4.6 from 487 ratings. Reviewers use a little paste and describe a bark-like colour when it dries. Bonsai Direct points smaller cuts to a tube and keeps a 190 g tub for larger wounds. The limits stay: Japanese-only text, paste on fingers, and tubes that split. It is the matching tool in the set, not a claim about every paste in Britain.
Why is there no English on the tube?
Reviewers say the instructions are in Japanese and that there is no English on the pack. You take the method from the listing and from practice: a small amount on a fresh cut, from the tube or a tool. You do not get a species list from the tube. A 4.6 rating does not mean the pack is easy to read, and the listing still conflicts on volume, with 100 g beside a 0.25 litre field.
Will a 500 g green tub do for a show tree?
No, if you care how the tree looks while the film is visible. Vividye reviewers call the 500 g paste extremely bright green, and one said they would not use it on bonsai. The tub can be a volume buy for garden cuts at £10.99. On a show tree the colour is the defect, and 500 g is more than a season of small dabs. Kiyonal reviewers mention a bark-like dry colour, which is why the tube is the pick here.
Can I use Provanto Arbrex on a bonsai?
You can get the gel onto the cut, and you will meet the same complaints: extreme stickiness, a brush cap that flies off, and a 300 g bottle that is out of scale. Arbrex is the garden top pick at £7.80 with 4.5 from 1,172 ratings. It is a poor fit for a small visible bonsai wound. Keep it for garden cuts you have already decided to seal.
What did UK reviewers say about drying and colour?
In the first 50 reviews, people describe a bark-like colour once the paste has dried, and drying in about one to two days. That is a review pattern, not a laboratory time, and a cold shed will slow it. The complaints beside the praise are Japanese-only instructions, paste on fingers, and tubes that split. Plan for a visible dab until it weathers or callus covers the cut.
Does the 0.25 litre field mean a bigger tube?
No. The listing's title, unit count, and item weight say 100 g. A liquid-volume field says 0.25 litres, which conflicts with those gram figures. Treat 100 g as the fill and ignore 0.25 litres as extra product. Squeezing out a large dose because the field sounds generous will bury a small cut. If the parcel feels nothing like a 100 g tube, query the order.
