CT: Bud pruning (pinching) and leaf pruning both aim to develop small branches and leaves. These methods have the same effect as branch pruning. They are applicable when branch pruning may not apply, such as when the bonsai trees have completed shapes, or when you only want to suppress the overlong branches on the tree without pruning them. For example, you can apply these methods to deciduous trees that have beautiful branches and leaves, such as Acer (Maple), Zelkova, Beech, and Hornbeam.
In addition, bud pruning is applied to trees whose branches have been pruned but their lateral buds are not growing well. Bud pruning is also used for conifer trees such as pine trees because leaf pruning may damage the plant and cause it to wither or tend to develop leaves of poor shapes.
Bud pruning (pinching) is to pinch by hand (Me Tsumi) or to prune with scissors (Me Kiri) the apical buds that grow out one after another. The overgrown apical buds disturb the healthy development of a bonsai tree’s shape. You can prune the apical buds with scissors or pinch them by hand before they grow out. For some tree species, such as the Japanese blackpine, pruning with scissors could cause the pruned parts to wither.

N: 1. bud (n): late 14c., budde, origin unknown, perhaps from Old French boter “push forward, thrust,” itself a Germanic word (compare Dutch bot “bud,” Old Saxon budil “bag, purse,” German Beutel), or perhaps from Old English budd “beetle.”
pruning (n): From verb prune (v.), early 15c., prouyne, from Old French proignier “cut back (vines), prune” (Modern French provigner), of unknown origin. Perhaps (Watkins) from Gallo-Roman pro-retundiare “cut in a rounded shape in front,” from pro- “forth” + retundiare “round off,” from Latin rotundus. Klein suggests the Old French word is from provain “layer of a vine,” from Latin propago.
Or the Middle English word might be identical with the falconry term proinen, proynen “trim the feather with the beak” (late 14c.), source of preen (Barnhart). Related: Pruned; pruning. Pruning hook is from 1610s; pruning knife from 1580s.
2. Removal of lateral buds from a stem to prevent them from developing into branches.
3. The removal of unwanted buds or very young shoots so as to prevent their developing into branches. Particularly during the training of young vines.
