The Japanese black pine bonsai is one of the most desired species of Bonsai. It has a very specific growing pattern which makes it unique among Bonsai trees and it is not a tree that the beginner should attempt to cultivate due to the time and care involved in upkeeping.
If you are an experienced Bonsai grower then this is the tree for you.
One of the great features of this species is that it is extremely adaptable to virtially any climate; hot or cold. This makes it a good choice for Bonsai enthusiasts who live in northern portions of the world.
So, what is the right way to trim a Japanese black pine bonsai?
Due to the thick needle growth patterns, you need to make sure you remove at least 50 percent of the needles, especially from the top section of the tree during the pruning process. Should you need to cut off a branch or cut into the trunk you MUST do this during the autumn season. This is because this is the time of year when the tree sap is at it’s lowest levels. Cover the cut with petroleum jelly to protect it against disease.
Repotting can only be done once the tree is between two and five years of age and only in the spring season. This is because spring is the season where your pine will gain the most growth and it will be much easier for the roots to take hold in new soil.
Do not wash the roots of the Japanese pine bonsai before you move it to it’s new home.
Your tree desires soil with an average moisture retention. If you really want to enhance the conditions in which your tree is growing you can add a nitrogen fertilizer late in the spring just as the new needles on the tree begin to grow hard. Besides this fertilizing, you should apply a high nitrogen fertilizer approximately two to three weeks prior to the onset of the autumn season.
