|Scientific/Botanical Name||Pinus Thunbergii|
|Description||These pine trees are highly tolerant of poor growing conditions, and thrive in nutrient-starved soils.|
|Position||Japanese Black Pine trees enjoy full sun and high temperatures, but roots are susceptible to burning in bonsai containers. As such, if it is grown outdoors, the container should be protected from the hot sun. The color of the leaves are a lighter green when the tree is grown in sunny locations, but they are a lush, deep green when the tree is grown in part- or full-shade.|
|Watering||While the tree can tolerate mild drought, it is better to keep Japanese Black Pine trees lightly-moist. Excellent drainage should be provided to minimize the potential for root rot. Water that has a pH level in the range between 5.5 and 6.5 is optimal for this tree.|
|Feeding||Japanese Black Pine is unusual in that it does not need to be fertilized. Nevertheless, the bonsai tree appreciates the application of Bio Gold, or something similar, between the middle of spring and early-fall.|
|Leaf and Branch Pruning||Significant pruning of the tree must be carried out between late-fall and early-winter so as to prevent or minimize sap bleeding. After cutting, apply putty cut paste to the edges of the exposed wound. Japanese Black Pines bonsai trees do become stressed from pruning, and they should be kept in the shade for about a month after pruning.|
|Re-potting & Growing Medium||Local climates will determine the re-potting schedule of Japanese Black Pine trees. Re-potting guidance should be sought from a local bonsai expert. The trees do like to have their roots rearranged each time the tree is re-potted. After re-potting, the tree needs to be placed in a shady location for three or four weeks until it becomes re-established. A soil mixture the 50 percent akadama and 50 percent pumice works best. Younger trees will need slightly more grit in the soil, and older trees will prefer a higher percentage of akadama in the soil.|
|Wiring||If wiring is to be undertaken, it must be carried out in late winter. Sap leakage will occur if wiring is carried out at any other time.|
|Notes||Japanese Black Pine bonsai trees are susceptible to attack by spider mites, but this usually only happens to trees that are not kept in optimal health. Nevertheless, it is advisable to inspect the tree on a weekly basis for spider mites. They appear as specks of red on the needles of the tree.|

And because of its hardiness, it has been widely used in architectural designs, outdoor gardens, and presentations.
The Japanese Black Pine is not just found in Japan. This lovely tree is also native to Korea and in north-eastern China. It is known in the wild as a tree with a very striking appearance. It has an irregularly-shaped gray bark that transforms to black color as the tree matures. Its leaves are richly-colored which makes it a visually-appealing ornamental plant.

About The Japanese Black Pine
Native to Korea, Japan and north-eastern China, the Japanese Black Pine is quite striking in appearance. The irregularly shaped gray bark gradually transforms into black bark as it grows older. Along the branches, the richly colored green leaves grow in needle-like shapes. Over time, the Japanese Black Pine can grow as tall as 100 feet. When kept in bonsai form, it becomes a miniature version of its larger brethren.
Each spring, the Japanese Black Pine produces red, egg-shaped female flowers. The male flowers produced are more of a reddish-yellow color and are mostly found on the branch tips. If users want to start new plants, they can use some of the tree’s seeds. Additionally, they can propagate it using cuttings or grafting techniques.
This sun-loving plant should always be placed in a mixture that contains 50/50 of pumice and akadama. Younger pines will like more pumice and older plants will generally prefer more akadama. No matter what, well-draining soils should be used that are between 5.5 and 6.5 on the pH scale.
General Care For Japanese Black Pine Bonsai
In general, the Japanese Black Pine should be grown outside in full sun. This gorgeous plant can tolerate temperatures that reach above 100 degrees. Just remember—if the plant is kept in the sun all summer, it will transform into a greenish-yellow color. This effect is perfectly normal, but if a user wants it to attain a different color they will have to put it in partial shade. Another thing to remember is to cover the roots. Although the plant can thrive in sunshine, a shallow pot combined with excessive sunshine can cause the roots to bake. Covering the pot with some kind of material can help the roots to stay protected.
It needs to be regularly watered, but the soil needs to dry out in between watering. This pine tree does not grow well in continuously moist soil. If users have to err with more or less water, choosing to water it a little less is better. It needs to be placed in a soil mixture and pot that promotes proper draining.
During the growing season, the Japanese Black Pine will need to receive extra attention. It will need to be watered and pruned more. Growers should use a sharp knife to do any pruning and put putty cut paste to stymie the wound. Pruning done in early fall often works better since sap bleeding is less of a problem during these months.
If individuals want to give it a more aged look they should bend the branches downward. To thin the leaves, gently pluck the needles that grow underneath and inside of the branches. Once this is done, the fissured bark will be exposed. The Japanese Black Pine can be grown in any bonsai style except broom.
Fertilizing & Repotting
This tree needs to be fertilized every two weeks during the growing season. Use a well-balanced liquid fertilizer for optimal results.
If it needs to be repotted, users should take advantage of a bonsai soil mix that drains quickly. Generally, this tree will not need to be repotted for at least two to five years. Growers can determine its repotting needs based off of the root growth and how old the tree is. If they do have to repot it, they should always be very careful not to remove too much of the tree’s roots. These roots should be carefully rearranged so they can develop a strong surface root structure. After the tree has finished being repotted, it should be put in only partial sunlight instead of full sun. After three to four weeks have passed, it can be moved back into stronger sunlight.
If the grower wants to promote ramification, they can do this after the growing season is over by trimming the shoots. Winter is also a better time to wire the tree. During other seasons, the tree can suffer from sap leakage and be damaged.
Overall, the Japanese Black Pine is extremely hardy. Ideally, it should be grown in USDA Zones five through eight. During the winter, the bonsai tree will have to be protected from severe winter weather. It is susceptible to minors, root rot, blight, borers, rust and scales so growers should keep an eye out for any potential problems.
Growers should always take time and work slowly to train their tree. Successfully growing a Japanese Black Pine bonsai tree can take years. If growers prune too much at a time, it can cause too much stress for the tree to handle. After the tree is pruned, it should always be put into partial shade for a couple of weeks to give it time to recover. If all of these steps are followed, users can enjoy having a beautifully, intricate bonsai plant at their disposal.

Seeds that sink have viable insides and are fertile. Now that you know which seeds are fertile and which ones are sterile, it’s time to germinate and eventually sow your seeds.
- Fill a pot with peat seed sowing mix
- Place the fertile Japanese Black Pine seeds on the surface of the mix. Do not cover this because seeds need light to sprout.
- Water the soil thoroughly to moisten the soil. Water should run off the sides of the container.
- Place this outdoors in full sunlight.
- Keep the soil moist and check this frequently so your soil won’t go dry. This seed will germinate for about 15 to 90 days.

Wiring bonsai trees
Using wires to train branches and to shape the bonsai trunk is one way to style a bonsai tree. A Japanese Black Pine can be styled to any kind except for broom style. Styling has to be started when the tree is still young. Wiring when the wood is mature is harder to do because the wood is stiff and this could cause severe damage to the trunk or branches as you try to move the hard and stiff branches. Wiring old wood can cause also lead to fractures within the tree and although these fractures may heal after quite some time, an ugly mark will be left on the fracture site.
Wiring young Japanese Black Pine is a good way to achieve a variety of bonsai tree style or design. It is also important to remember to remove the wire as soon as you have achieved the style you want. As much as possible, the wire should be removed the same season it was attached.
Important wiring techniques
Wiring is a very popular strategy to shape a bonsai tree. You will be able to style and train bonsai trees safely, effectively and quickly by wiring. Wrapping wire around the young branches of a Japanese Black Pine bonsai tree, you will be able to reposition its branches to the shape or style you want. It will take a few months before the branches are ready and this is according to the style you want as well. There are a number of styles that you can use to shape a Japanese Black Pine tree.
Shakan Bonsai Style
The Shakan bonsai growing style is also called the slanted bonsai tree because it looks like a slanted tree. The trunk protrudes from the soil in a slanted position and the tree straightens out to an outward position with the trunk in a 60-80 degree angle. To create that classic slanting and windswept style, you can use strong wiring which helps control the growth of the main trunk. Wiring may also be used to control the height of each branch. Another way is to apply strong sunlight from one direction only.
The Dramatic Fukinagashi looks like a windswept head of hair during a storm. This style is s more common than you may think. In this style, the branches and the trunk grow to one side only to recreate the effect of strong blowing wind moving in one direction. Wiring and delicate pruning are used to achieve this style.
The Shari Bonsai Style is a style that shaves the bark to keep new growth from appearing. A popular Shari style is a stair effect. Some branches may be long or short in this style and this is mostly achieved by wiring and a lot of pruning. The leaves on the top of the tree create a perfect aesthetic balance. The Shari bonsai style is based actually based on the natural development of some bonsai plants. A bald or barkless area on the trunks usually develops and this is mostly due to harsh weather conditions.
Seki-joju or Rocky Terrain
The Seki-joju or Rocky Terrain style is basically growing bonsai around an obstacle such as a jagged or smooth rock. This also happens naturally when the roots of trees grow underneath and along the sides of nearby rocks. Roots may also crawl around the rock surface as the trunk of the bonsai has formed. The tree will continue to grow in a straight manner despite various obstacles in its path.
The Literati style has a skinny trunk and has a number of curved leaves. Growers and bonsai enthusiasts say that this style depicts the struggle in nature to preserve even the tiniest form of life. There are a few bald spots along the trunk to recreate dead branches in this style. The Literati bonsai style is naturally seen in trees that are located in densely populated tree areas. The trunk is naturally bent and grows crookedly as the tree begins to mature.
This bonsai style is similar to the cascading style. A section of the trunk is grown straight while a branch grows outward and slightly downward. A small area of the trunk is left before the thick branches are located. These grow in different directions. The leaves are low-lying and the plant requires a deeper pot to control and preserve the formation.
You can wire your bonsai plants to train them and you can do this any time of the year. During the growing season or as the tree branches grow thicker and faster, therefore, the wire can cut through the bark which can lead to marks and scars. This is why you must not forget to remove the wire. You must also check your bonsai wire constantly while this is wired, you need to check your tree regularly and remove the wire as soon as the season changes.
The type of wire to use
There are two kinds of wire to wire a Japanese Black Pine or any bonsai tree. You may use anodized aluminum and annealed copper and there are very striking differences between the two.
Aluminum is safe for deciduous trees while harder and stronger wires like copper are for harder species like conifers and pines. It could be a challenge to wire bonsai if you are new to growing bonsai trees. Therefore, you must initially use the anodized aluminum wire which easier to use and is readily available anywhere. Wire for wiring bonsai also comes in a variety of thicknesses. The most commonly used is the 1 mm to 4 mm variety. To prevent injury to the branch or trunk, you must wrap these with raffia-soaked water. Raffia is palm fiber that you can purchase from garden stores. This will protect branches from damage as a result of bending and moving.
Step by step instructions on how to wire a bonsai
- Decide if you will use a double or single wiring.
- Select the thickness of the wire you will use.
- Take one end of the wire and wrap around the branch you will reposition. Do this at a 45-degree
- Wrap the wire neatly in line along the branch.
- Slowly bend branches into position to prevent any damage or injury to your bonsai tree.
- Use a guy wire to bring down branches which are too high. Wrap a protective material around the branch and place a hook at the end of the wire. Secure the hook and use a thick piece of wire at the end and allow this to hang from the hook.
- Extend and attach the guy wire to a strong root.
- Check your tree regularly after attaching wires to Remove the wires as scheduled.
- After wiring, monitor the growth of your plants. Place it under sunlight and water it every day.
Post-wiring care for your Japanese Black Pine
After wiring your Japanese Black Pine bonsai tree it needs aftercare. Place this in a pot preferably in the shade to allow it to recuperate. Feed your bonsai nutrients to help it recover. Remove the wires on schedule to prevent these from injuring or cutting the tree bark. Follow the time you need to remove the wires. When removing cut the wires at every turn. Do not recycle the wire you used because this makes it harder to remove the wire. You will only end up damaging your tree as well. Removing wires at every turn makes it a lot easier to remove the wire. Monitor for plant overall health and let this rest to completely recuperate.
9) How to prevent pests & diseases
Japanese Black Pine bonsai trees are very hardy but are still prone to pests like spider mites. As mentioned, spider mites are small insects with huge appetites. These can bite and suck the nutrients from the leaves of your tree and destroy it. It’s hard to tell if your tree has spider mites but usually, you can tell by the presence of white, wispy webs that can cover the entire body of your plants.
You must be diligent and inspect for spider mite infestations. Check for red specks at the underside of leaves; if you find these then you have spider mites. This is usually found here because this is soft and easy to bite through.
Spider mites may be removed by spraying the leaves with water to remove the mites. This should be done continuously to completely remove these persistent pests. Pesticides may also be used but this should be done cautiously.
Another condition that you must be wary of is root rot which happens when the root is immersed in water for a long time. This may be avoided by using the most suitable soil for bonsai trees like a sandy clay soil which can absorb and drain water well. You must also avoid overwatering your plants and water only when the soil is high and completely dry.
You may also use the help of farmer-friendly creatures like ladybugs and earthworms. Ladybugs will be able to eat and eradicate spider mites and other pest infestations. Earthworms can fortify the soil and keep it aerated to prevent root mold and rotting.
