Japanese Larch Tree Seeds

Japanese Larch is a fast-growing, deciduous conifer prized for its soft blue-green needles, attractive reddish-brown bark, and exceptional golden-yellow fall color. Native to Japan, this hardy tree develops a graceful pyramidal form when young before maturing into a broad, elegant specimen. Unlike most conifers, Japanese Larch sheds its needles each autumn, creating a stunning seasonal display. It is an excellent choice for landscapes, windbreaks, reforestation projects, bonsai enthusiasts, and timber production.

Germination Instructions

Japanese Larch seeds require 30 days of cold moist stratification before planting.

2. Place the mixture in a sealed plastic bag and refrigerate for 30 days at approximately 34–41°F (1–5°C).
3. After stratification, sow the seeds about 1/8 inch deep in a well-draining seed-starting mix.
4. Keep the soil consistently moist but not waterlogged.
5. Place the container in a bright location with temperatures between 65–75°F. Germination usually begins within several weeks under favorable conditions.
