After the trunk is bent, the twigs can be pruned to form a flaky needle layer, so as to achieve the effect of short branches and dense needles and beautiful layers. Pruning is generally carried out in sunny days, because the wound is easy to dry and shrink in sunny days, reducing fat overflow. Pruning of five-needle pine bonsai includes bud cutting and pruning, which usually only need to be done once a year 1 time.

1. Trim:

Five-needle pine is a verticillate branch, with at most 2 branches left in each trunk, generally only 1 branch. Cut off other redundant branches and branches that are too dense, too thin and useless, and cut off long branches and strong branches. Long branches are developed from terminal buds and can be combined with tender buds for cutting. It is necessary to adjust the growth direction of the main branches to make the crown of Pinus pentaphylla ventilated and transparent.

2. Cut the buds:

By cutting buds, pine buds will not grow in vain, but single buds can promote multiple buds, making branches short and dense, needles neat and lamellae clear; It can concentrate nutrients on the remaining buds, which is beneficial to the development of the remaining buds, with strong branches and beautiful crown. Bud cutting is usually carried out after the new buds grow and before the new needles are pulled out. Every March-April, pay attention to new buds and cut them off immediately.

The budding tool is small scissors or sharp branch scissors. Bud cutting standard: when the terminal bud is 5-6 cm long, cut 2 cm; The lateral buds are short, only 2-3 cm, cut1-2 cm; The whole bud can be cut off. After cutting off the buds, combined with maintenance and management, weeds on the basin surface should be removed, soil should be loosened 1 time, thin fertilizer should be applied 1 time, water spraying on the leaves should be strengthened to promote the germination of lateral buds and new needles.
