Best Cut Paste and Wound Sealants for Bonsai
Updated How we research
A fresh cut loses moisture at the edges, and dieback around a wound turns a tidy chop into a scar that takes years to close. Cut paste seals the surface while the callus rolls in. Products vary in base, from putty you knead and press on to gels and pastes that spread thin. They also differ in how long they stay flexible, and in whether they peel off later or simply weather away. We weighed adhesion in wet weather against how easily the paste comes off once callus has formed, since a hard shell can distort the roll. Color mattered too, because a paste that blends is easier to live with on a display tree. Putty suits large chops and hollowing work. Spreadable pastes suit small pruning cuts and grafts. Keep a tub out of the sun so it stays workable when you need it.
