In spring, the trident maple (Acer buergeranum) blooms with bright yellow, eye-catching flowers. But the real show is in fall when its leaves turn shades of yellow, orange and red. If you don't have room in your yard for this 30-foot tree, the trident maple is also grown as a bonsai or container tree. Whether you plan to grow your trident maple as a bonsai, potted or landscape tree, start it in a small pot. Once the tree is a few inches tall, you can transplant it into the ground in warm weather or into another pot.
Soak the seed in hot water for 24 hours.
Fill a 4-inch pot to within 1/2 inch of its lip with potting soil. Pat the soil down gently with your hand to firm it and remove any air pockets.
Water the soil until water drips out of the drainage holes in the bottom of the pot.
Plant the trident maple seed so that it is covered with 1/2 inch of soil.
Place the trident maple's pot in a sunny spot that will remain at or above room temperature. Keep the soil moist until the seed germinates.
