Earlier this week, we looked at the three basic types of buds found on black pine bonsai. If we make this cut in the middle of the growing season, typically in June in the northern hemisphere, we can expect adventitious buds to appear from the stub we left behind. If we make this cut at other times of the year, there is a chance adventitious or needle buds will develop, and there is a chance that the branch will die back. The closer we make the cut to the middle of the growing season, the better the odds the tree will develop adventitious buds. A related technique involves cutting past the spot where we decandle pines. The closer we make the cut to the middle of the growing season, the better the odds the tree will develop needle buds.

Japanese Black Pine Bonsai Tree
Bonsai Topics. History of Bonsai. Bonsai mini course.
Black pines can reach the height of 40 m, but rarely achieves this size outside its natural range. Bark is gray on young trees and small branches, changing to black and plated on larger branches and the trunk; becoming quite thick on older trunks. In North America this tree is subject to widespread mortality by the native American pinewood nematode, Bursaphelenchus xylophilus , spread by means of beetle vectors.
