Dwarf Japanese Maple Tree Seeds

The Mikawa Yatsubusa Japanese Maple is one of the most sought-after dwarf Japanese maple cultivars, prized for its exceptionally dense branching, tightly layered foliage, and naturally compact growth habit. This slow-growing ornamental tree forms a beautiful rounded shape that requires very little pruning, making it ideal for small gardens, patios, courtyards, containers, bonsai, and Japanese-style landscapes.

In spring, its rich green leaves emerge in tightly overlapping layers, creating a unique textured appearance unlike any other Japanese maple. During autumn, the foliage transforms into brilliant shades of gold, orange, and crimson, providing spectacular seasonal color. Its manageable size and elegant form make it a favorite among collectors and landscape designers alike.

Germination Instructions

1. Remove the papery wing from each seed.
2. Place the seeds in a heat-proof container and pour hot water (no hotter than 110°F) over them. Allow the water to cool naturally and soak the seeds for 24–48 hours.
3. Drain the water and place the seeds into a plastic bag containing slightly moist peat moss, coarse sand, or potting soil. Poke several small holes in the bag for air circulation.
4. Refrigerate the bag for approximately 120 days. This cold stratification period breaks seed dormancy. Some seeds may begin producing small roots before planting.
5. Fill 4-inch pots with a quality potting mix. Plant the seeds about 3/8 inch deep and lightly cover them with soil.
6. Water thoroughly after planting and keep the soil evenly moist but never waterlogged.
7. Seedlings generally emerge within 1–2 weeks after planting if germination has already begun during stratification.
8. Place young seedlings in bright, indirect light or light shade to protect tender foliage from scorching.
