Growing Japanese Cedar from Seed: A Step-by-Step Guide

Japanese Cedar, also known as Cryptomeria japonica, is a majestic and fast-growing tree that is highly prized for its timber and ornamental value. If you are interested in growing Japanese Cedar from seed, follow this step-by-step guide to achieve success.


Step 1: Seed Collection

The first step in growing Japanese Cedar from seed is to collect the seeds. This can be done by harvesting cones from mature trees in the fall when they are fully ripe. The cones should be dried and stored in a cool, dry place until you are ready to extract the seeds.

Step 2: Seed Extraction

To extract the seeds from the cones, place the cones in a bag and gently crush them to release the seeds. Separate the seeds from the debris and store them in a sealed container until you are ready to plant them.

Step 3: Seed Treatment

Before planting the seeds, it is recommended to treat them to improve germination rates. One method is to stratify the seeds by placing them in a moist paper towel in the refrigerator for several weeks. This mimics the natural winter conditions that the seeds would experience in the wild.

Step 4: Seed Planting

Once the seeds have been treated, it's time to plant them. Fill a seed tray or small pots with a well-draining potting mix and plant the seeds about 1/4 inch deep. Water the soil thoroughly and place the tray in a warm, sunny location.

Step 5: Seedling Care

Keep the soil consistently moist but not waterlogged as the seeds germinate and grow into seedlings. Provide adequate sunlight and maintain a temperature of around 70-75°F for optimal growth. Thin out any overcrowded seedlings to ensure healthy development.

Step 6: Transplanting

Once the seedlings have developed several sets of true leaves, they can be transplanted into larger pots or directly into the ground. Choose a location with well-draining soil and ample sunlight for the best results. Water the seedlings regularly to help them establish in their new environment.

Step 7: Continued Care

As your Japanese Cedar trees grow, continue to provide them with regular watering, especially during dry periods. Mulch around the base of the trees to retain moisture and suppress weeds. Prune the trees as needed to promote healthy growth and shape.

Step 8: Harvesting

Depending on your goals for growing Japanese Cedar, you may choose to harvest the trees for timber or simply enjoy them for their ornamental value. If harvesting for timber, wait until the trees have reached maturity, typically around 30-50 years old, for the best quality wood.


Growing Japanese Cedar from seed can be a rewarding experience that allows you to cultivate these beautiful trees from the very beginning. By following these steps and providing proper care, you can enjoy the beauty and benefits of Japanese Cedar in your own landscape.
