Pine trees are a common tree throughout the world, but some are more special than others. The Japanese Pine Tree or Black Pine is one such species. Whether as a diminutive age-old bonsai or soaring at a hundred feet above your head, this is one such tree that you want to know about.
What Is A Japanese Pine Tree?
The Japanese Pine Tree (Pinus thunbergii), also known as black pine, is native to Japan and South Korea. It's a beautiful conifer with dark black trunks and lovely sculptable branches. It's a popular garden tree in its native Japan and is often used for bonsai as well as natural plantings.
This gorgeous tree is featured in botanical gardens, such as the Japanese National Garden in Tokyo and the Seattle Japanese Garden, because of its beauty and interest as it is sculpted over time. The bark, which starts out grey, changes to black and continues to thicken over the lifespan of the tree. Under perfect conditions, this tree can reach as high as 100 feet, but that is rarely seen outside of natural habitats.
How To Grow A Japanese Pine Tree
Japanese Pine Trees are one of the most common species to its native Japan. Grown primarily outdoors for gardens, it is also sometimes grown to act as a hedge, a windbreak, or historically to harvest for turpentine and wood for construction. It is a species of pine that can be grown in an outdoor container and, in addition, is highly prized as a species to be used for bonsai.
In a natural setting, the Japanese or Black Pine could grow to heights between 80 and 100 feet. However, in a typical garden setting, it is more likely to settle around 25 feet. It grows between 2 and 3 feet per year and has a long lifespan with some trees, in the right conditions living as long as 150 years.
The Needs Of The Japanese Pine Tree: Soil, Light, & Feeding
The Japanese Pine Tree does best in full sun but can do partial shade. It's hardy in USDA Zones 5-9. As for soil, it prefers moist, well-drained soil but can tolerate some sand, salt, and seaside. This factor is why the black pine has been used to help with seaside erosion on certain coastlines. When you choose to fertilize, you'll want to select an acid-based fertilizer and apply it during the growing season.
Steps For Planting A Japanese Pine Tree
If you're starting your Japanese pine tree from seed, you'll want to plant one seed per seedling pot in loose potting soil. Once your seedling has reached 2-4 inches tall, then you can place it either in its permanent outdoor location, or the pot where it's going to live. Use good soil and mulch around the top to prevent weeds. You can let the top of the soil dry out between waterings, but once it's dry, then water again.
