Growing a Maple Tree from a Sprouted Seed: Bonsai Potential

You found a sprouted maple seed protected behind a rock over winter. Want to grow it into a bonsai but unsure of variety-specific needs.

Hybrid vs. Heirloom

Most nursery maples are hybrids; seedlings won’t replicate the parent. If the seed came from an older tree, it may be an heirloom and grow true.

Seedling Care

1. Pot in 10″ container with fertile potting soil.
2. Place under fluorescent lights or east-facing window.
3. Water only when soil is dry 2″ below surface.
4. Fertilize every 2 weeks at half strength with high phosphorus/potassium formula.

Transplanting to Garden

At 4 feet tall, harden off: 1st day shaded 2 hrs, 2nd day 6 hrs, 3rd day 12 hrs, 4th day full day, gradually increasing sun. Transplant after 7 days if no frost danger.
