Miyasama trident maple

Miyasama trident maple key facts

Growing Difficulty

Beginner-friendly

Lifespan

Little data for this strain

Size

Trident maple reaches 10–20 m, but Miyasama is mostly sold as rooted cuttings and small bonsai

Watering

Fertilizer (April–September, pausing from the rainy season through midsummer)

Light & placement

Full sun from spring to the rainy season; from then through summer keep under 70–80% shade cloth. Remove it after early September to bring out autumn colour

Watering

Large leaf area dries it quickly: 1–2 times daily in spring, 2–3 in summer, every 2–3 days in winter. Water less just after defoliation

Temperature & overwintering

Cold-hardy, but dry winter wind or snow can kill twigs. After 2–3 frosts shelter it under the bench, and bring it out once late frosts are over

Soil & repotting

Roots grow fast and pot-bind easily. Repot young and small trees yearly and mature ones every 2 years, mid-Feb to early March before budbreak

Fertilizer

Light organic fertilizer every 30–40 days April–September, pausing in the rainy season and midsummer. Feed mature trees sparingly to avoid leggy growth

Pruning & styling

From mid-April, when 2–3 leaf pairs open, pinch shoots back to 1–2 nodes; repeat 2–3 times until September to build twigs. Defoliate vigorous trees

Pests & cautions

Tough, but watch for aphids, scale and longhorn beetle borers; dormant-season spraying is the main prevention. Young plants are hard to tell from ordinary trident maple

About Miyasama trident maple

Miyasama trident maple ("Taiwan maple"), propagated from a tree linked to the Fushimi-no-miya family, is a beginner-friendly bonsai variety said to feature finely divided branching and attractive autumn color, usually grown as compact potted stock.

7 things to know before growing Miyasama trident maple

1. 1Choose a Sunny Spot

   Miyasama trident maple thrives with plenty of sunlight and good air circulation, so keep it outdoors in a bright spot. In the height of summer, strong direct sun or western afternoon light can scorch the leaves, so moving potted trees to partial shade during the hottest hours helps protect them.

2. 2Water Thoroughly When Dry

   Because bonsai pots hold only a small amount of soil, they dry out quickly. Water generously whenever the surface soil feels dry, letting water run out the drainage holes, and make sure the soil doesn't stay constantly soggy.

3. 3Use Well-Draining Soil

   Maples dislike soggy roots, so a bonsai soil mix based mainly on akadama with good drainage and aeration suits Miyasama trident maple well. A ready-made bonsai soil blend makes ongoing care simpler.

4. 4Repot Regularly

   Miyasama trident maple's roots grow fast and quickly become pot-bound. Repot young trees and small bonsai every year, and mature trees every two years, from mid-February to early March before the buds start to move. This is also a good time to remove old soil and trim away any damaged roots.

5. 5Enjoy Its Autumn Color

   Miyasama trident maple is valued for its fine branching and especially attractive autumn foliage. Keeping it outdoors in full sun through autumn, where it experiences the day-night temperature swing, brings out richer color. Once the leaves drop and the tree enters dormancy, cut back on watering frequency.

6. 6Prune to Shape the Branches

   Because it naturally produces fine, dense branching, regular pruning of overly long shoots helps maintain the delicate silhouette typical of small bonsai. Repeated pinching and trimming during the growing season encourages even finer ramification over time.

7. 7Choose Stock by Branching

   Miyasama trident maple is most often sold as young cutting-grown saplings or ready-made small bonsai. When choosing one, look at how the branches and leaves are divided and check for healthy, even leaf color to help pick a good specimen.
