Pinus Densiflora

Hardiness zones 3-7, (-37°C/-35°F, -15°C/-5°F) in Winter. Grow in fertile well-drained soil. Keep a bit on the dry side; increase sand for drainage in soil mix. The tree can tolerate drought. Grows best in semi-shade to full indirect light. Doesn’t like extreme heat; give afternoon shade. 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 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. Cold stratification This will break their dormancy. It creates a cold and moist environment for the seeds. Mixed in seeds with slightly moistened vermiculite or peat, only damp in a ziplock bag. Close zip bag shut and store it in the salad crisper compartment of your refrigerator. If any seeds begin to sprout during the cold stratification, simply remove the seed and plant.
