Cherry Blossom Tree Seeds - 12 Seeds

Culture, Climate & Bonsai Wintering

Hardy in USDA Zones 5–8. Cherry trees prefer rich, fertile, and well-draining soil. They need full sun to produce the best floral display but benefit from a layer of mulch to keep their roots cool. Crucial Bonsai Note: If growing your cherry tree in a shallow bonsai pot, you must protect its roots from freezing during the winter. Overwinter potted bonsai in an unheated garage or cold frame (they need the chill of winter to break dormancy, but not extreme freezing).

Mandatory Seed Prep (Cold Stratification)

CRITICAL STEP: Cherry seeds have deep natural dormancy. They will NOT sprout if planted dry and warm.

1. Soaking: First, soak the seeds in warm water for 24 hours to soften the hard outer shell.
2. Cold Stratification: Place the soaked seeds inside a slightly damp (not dripping wet) paper towel or sphagnum moss. Seal them in a ziplock bag and place them in the refrigerator at 35–45°F for 60 to 90 days. This simulates winter. Check occasionally for mold or early sprouts.

Sowing & Germination

After the 60-90 day cold treatment, plant the seeds about 1/2 inch deep in pots filled with sterile, well-draining seed-starting mix. Keep the soil warm, ideally around 65–75°F (18–24°C), and consistently moist. Germination for tree seeds is highly erratic—some may sprout in 3 weeks, while others take much longer. Do not throw away your trays too early!

Care & Blooming Expectations

Transplant seedlings outdoors or into larger pots once they have several sets of true leaves and frost danger has passed. Extreme patience is required: Seed-grown Cherry trees focus entirely on vegetative growth during their early life. It generally takes 3 to 7 years for a tree grown from seed to reach maturity and produce its first display of blossoms.

Pruning, Pests & Diseases

Prune your cherry tree in late winter to shape the canopy and remove crossing or dead branches. Watch for common tree pests like aphids, scale, and Japanese beetles. Cherry trees can be susceptible to fungal leaf spots; ensure they are planted in an area with good air circulation and water at the base to keep foliage dry.
