Pinus densiflora aka Japanese Pine
Taxonomy
Pinus densiflora, also known as the Japanese red pine, Japanese pine, or Korean red pine, is a slow-growing, evergreen conifer native to East Asia. In China, it is referred to as 赤松 (red pine). This rare houseplant forms a compact, rounded mound and has bright green to yellow-green needle-like leaves. The small, ovoid cones are yellow-brown in color. Japanese Red Pine thrives in direct light, preferably within 1 foot of a window, and requires regular watering for optimal growth. It prefers well-draining soil and does not require additional fertilizers if repotted when it doubles in size. Native to Eastern Temperate Asia, Japanese Red Pine belongs to the Pinus genus.

Difficulty
With its straightforward care requirements, Japanese Pine is a hassle-free plant that anyone can enjoy.
Water
Japanese Pine should be watered regularly, allowing the soil to dry out between waterings.
Soil
Japanese Pine loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
Japanese Pine thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Tanyosho Pine.
Toxicity
The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.
Fertilizer
The growth rate of Japanese Pine is slow and it doesn't necessitate additional fertilizing. By changing the soil in its pot annually, the plant should be provided with adequate nutrition. It is crucial to keep in mind that plants derive their energy from the sun, not fertilizers.
