Plant Needs
Sunlight
Full sun to partial shade; best bark color and flowering occur in full sun, with partial shade tolerated in hot summer climates
Watering
Water deeply when the top 5–7 cm of soil dries out; avoid overwatering to prevent root rot in heavy clay soils
Temperature
Hardy to -15°C; thrives in cool temperate climates and avoids prolonged extreme heat above 30°C
Characteristics

Fertilization
Apply balanced slow-release fertilizer once at bud break. Use low-nitrogen fertilizer to prioritize bark health over excessive foliage growth
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base and water in to avoid attracting pestsPruning
- Remove dead, damaged, or crossing branches in late winter to maintain an open, airy shape
- Thin crowded inner growth to improve air circulation and highlight bark display
- Prune suckers at the base regularly to prevent overcrowding and redirect energy to the main tree
- Avoid heavy pruning, as it can reduce the distinctive peeling bark production
