Pruning: Japanese Black Pine bonsai should be pruned at optimal times to ensure success, Larger branch removal should be done while the tree is slowing down its growth to reduce sap bleed, the best time for this is during autumn. The trees candles should be pruned during summer to promote further budding for ramification. Depending on the size of your tree you will either do this early or late summer, larger trees will be done first while smaller tree will be done later to make sure the size of the new needles is in proportion to the tree.
  4. Training: Japanese Black Pine bonsai can be trained into a variety of shapes and styles, and this requires the use of techniques such as wiring, decandling, bud selection and needle plucking. Wiring should be done in late summer or autumn while the tree is still growing but at a slower rate, if wired in spring the wire can bite in fast on a young healthy tree, as the tree gets older the wiring can be done earlier in the growing season.
