Japanese Black Pine Care Sheet
The Japanese Black Pine Bonsai Tree from our wholesale nursery is native to Japan and in undoubtedly an excellent example of a classic bonsai pine species. In nature, these trees can grow to heights of 25 to 30 feet and are commonly found in gardens and community parks throughout Japan. These trees make excellent bonsai trees for beginners (and masters too for that matter!) because they are extremely resistant to common diseases and very tolerant to poor soil conditions, making them easy to maintain and even easier to enjoy.

The Japanese Black Pine is set apart from the rest by its distinct needles, which exhibit a vivid, deep green color that is complemented by a trunk with distinctly attractive, rough bark. The needles are long, and are often trimmed by the owner to maintain a “miniature” look. The branches grow out powerfully from the trunk of the tree, covered in a crackly bark which gives the appearance of age – which is a basic fundamental in the art of bonsai!
The Japanese Black Pine is naturally a drought tolerant tree, so it will be unharmed if you allow it to dry out in between watering. So if you travel frequently, this is a perfect tree for you! We recommend that you allow the soil to dry before the next time you water, and mist the needles as well, which will help raise the humidity levels around the tree.
Since the Black Pine is native to Japan, it is not naturally accustomed to extreme heat. So, during the summer when temperatures begin to rise, we recommend that you move the tree to a location where it still receives sunlight, but not the intense heat of the day. You should also mist the tree daily to help keep the foliage and roots cool, especially if you live in a warm region of the United States.
We recommend that you keep this bonsai tree in full sun during the day when the weather is not too hot in an area with respectable air circulation. You should slightly turn the tree every two weeks to make sure that the entire tree gets sunlight, and not just one side otherwise it could result in uneven growth.
Nursery Tree Wholesalers recommends that you fertilizer your Black Pine every four weeks with an acid based fertilizer during the spring and summer.
Trimming and shaping should be done in the early spring, just as growing season begins. When new buds begin to form in undesired locations, simply pinch them off with your fingers, being careful not to disturb the bark of the tree. You can also use a technique called candling, which will help dwarf the needles and increase the density of the foliage.
You should repot your black pine every 3 years in the spring, replacing the soil with a soil mix of calcinated clay and coarse sand. You should also make sure that the new mixture includes a helpful fungus for pines called Mycorrhiza. This fungus helps the pine’s ability to absorb nutrients from the soil and will encourage the growth of fine, hair-like roots. Ask your local nursery for help finding a soil that is suitable and will keep your bonsai healthy.
As stated above, the Japanese Black Pine is a very “disease free” bonsai tree. They very, very rarely have pest issues, and will generally remain in good health as long as they are maintained. A healthy tree goes a long way to keeping diseases away from it! Be sure to regularly clean the needles with a damp cloth, and fertilize during the growing season to ensure that the tree remains vigorous.
