15 Seeds Pinus Densifora (Japanese Red Pine) Bonsai

Germination First, scarify the seeds. For faster germination, soak the seeds in slightly hot water for 24-48 hours, followed by 4-6 weeks cold stratification before sowing at 1/4″ deep in sterile gardening soil. Keep damp soil, not soaking wet. Keep pot in warm situation, 68-75°F. Germination usually occurs several months. It can be more depending on their degree of unbroken dormancy, don’t give up. Scarification / Stratification Seed coats may be so hard that they are impermeable to water. They need to be scratched or broken using a knife or sandpaper, in order to germinate. Chip the seeds with a sharp knife or make a few swipes with a sharp edged file or use sandpaper to allow moisture being more readily absorbed.

Product Features

  • Japanese red pine is widely used as a bonsai tree. If left to grow naturally, it reaches 30 to 50 feet tall. A truly classic and beautiful tree for bonsai. A distinguishing feature of this tree is the often crooked or sweeping trunk which shows reddish-orange peeling bark; very showy trunk.
  • The tree wants to grow with several trunks but can be trained to grow with a single trunk. It has soft bendable branches that tend to sweep upward. Needs little pruning to develop a strong structure.
