How to Grow a Cherry Blossom Tree from Seed in 4 Simple Steps

The iconic cherry blossom tree, also known as sakura, is adored for its stunning canopy of pink or white flowers that emerge in spring. Though native to Asia, these ornamental trees can thrive in temperate regions worldwide. With some preparation and care, you can grow a cherry blossom tree yourself from seed.

Step 1 Collect and Prepare SeedsIn autumn harvest cherry blossom seeds when the fruit pods split open. Select plump mature seeds and perform a float test to eliminate any duds. Viable seeds will sink, while hollow ones will float. Next, scarify or weaken the outer seed coating using sandpaper, nicking with a knife, or soaking in hydrogen peroxide for 10 minutes. This allows moisture to penetrate and trigger germination.

Step 2 Stratify SeedsCherry blossom seeds require a period of cold, moist conditions to break dormancy Place scarified seeds between damp paper towels and refrigerate for 8-12 weeks. Check periodically for sprouting, which signals they are ready to plant. This stratification mimics winter and tricks seeds into thinking they’ve experienced enough chilling hours to initiate spring growth.

Step 3: Plant Stratified Seeds
In early spring after chilling, plant stratified cherry blossom seeds in containers or directly in the ground. They should be sown 1-2 inches deep in well-draining soil. Aim for a sunny, sheltered location. Water regularly to keep soil moist but not saturated. Young seedlings emerge in 2-4 weeks when soil temperatures warm. Pot up seedlings once they produce 2-3 sets of leaves.

Step 4: Care for Seedlings
Cherry blossom seedlings need protection from intense sun and extreme cold or heat their first year. Provide partial shade if planted outside or bring pots indoors during temperature swings. Water 1-2 inches per week and fertilize monthly during the growing season. Transplant outside the following spring once seedlings are 2 feet tall. With ideal care, they will flower in 4-7 years from seed. Enjoy your homegrown specimen!

Tips for Success:

• Source seeds from named cultivars for desired flower colors like ‘Tai Haku’ (great white) or ‘Beni Yutaka’ (pink). Seedlings from open-pollinated trees produce unpredictable traits.

• Check seeds frequently during stratification to plant once sprouted, usually 6-10 weeks. Don’t let seeds mold or sprout too long before planting.

• Shelter young trees from wind, which can damage branches until the tree matures. Stake trees while establishing to prevent uprooting.

• Water weekly for the first few years and provide extra water during dry periods. Mature trees are quite drought tolerant.

• Apply organic mulch around the base to conserve soil moisture and reduce weeds. Avoid mulch touching the trunk to prevent rot.

With preparation through stratification, attentive care of seedlings, and proper planting, you can grow gorgeous cherry blossom trees from seed. In just a few seasons, your efforts will be rewarded with abundant floral displays and iconic spring blooms.
