What do you call a short form of the Japanese black pine tree? Any idea? In the botanical world, the tree is labeled as Pinus Thunbergii, however, the world of bonsai has named it differently. You know what it is known as- the black pine bonsai. This bonsai is an out and out favorite. Loved by many people, who’re interested in bonsai work, this will not be good to go with for all those beginners out there. It requires a tremendous piece of dedication and patience to spend all the time this plant requires for you to prune and trim it with great care. Another fact that pine trees have a foliage that resembles a needle in shape makes it distinct from other trees of its kind.
Should you be interested in growing pine bonsais, I am sure, you would eye the black pine bonsai very closely. Yes, its ability to adapt to testing conditions characterized by extreme climate makes it a unanimous choice. Its twisted trunk, thick and dense foliage, a tender bark that is either green or purplish in color and, finally, its seeping buds make it a wonder to watch and sample.

You may ask whether there is any difference in the soil from which it derives its nutrients. Naturally, there is one and it has to deal with the moisture content of the soil regardless of its type. Soil with average moisture would do for a black pine bonsai. The process of supporting its growth gets better when a small amount of enrichment is done to the soil by adding a required quantity of low nitrogen fertilizer especially during the later phase of spring just when the new needles begin to grow. Afterward, a high quality high nitrogen fertilizer must be added from the late spring stage until autumn arrives.
While pruning the black pine bonsai you must remove around half of the leaves present at the top. As this tree has pretty thick foliage, you may not be able to prune properly unless you’re paying heed to this activity. A simple tip is to apply petroleum jelly on the face of the wound that resulted due to pruning.
Removing all the other buds except two will make way for a formation in which the shoot resembles a fork. Only the weaker branches and the buds present on black pine bonsai should be saved from pruning. You should chop off the remaining strong buds, in a bid to make way for weaker buds to gain strength. It is always a part of the procedure to remove such heavy parts during the autumn season when there is minimum sap.
In general, the buds left behind after pruning must grow into a replica of candle in its formation. This process starts in the mid of spring and continues until there are candles of different lengths formed. While the top part of the candle formation is generally pruned for good results, the ones at the bottom are also pruned when the shoots are cut off at the year-end. Other specifics on repotting, seed germination of black pine bonsai should also be looked into before setting into the process of growing a black pine bonsai.
