Plant Needs
Sunlight
Full sun to partial shade; full sun exposure is required for the most vibrant fall foliage color
Watering
Deep, infrequent watering once established; drought-tolerant, avoid overwatering to prevent root rot
Temperature
Cold-hardy to -30°C; tolerates summer temperatures up to 35°C, with better performance when provided with occasional moisture during extreme heat
Characteristics
- Leaf: Deeply lobed, bristle-tipped leaves (7–15 cm long); glossy green in summer, turning vivid scarlet in fall
- Flower: Male flowers are yellow-green catkins; female flowers are small, reddish axillary spikes
- Bark: Gray-brown, developing furrowed, blocky ridges as the tree matures
Care Guide
Watering
Deep watering every 7–10 days during prolonged dry spells; maintain moist but not waterlogged soil
Fertilization
Apply balanced slow-release fertilizer once in early spring before new growth emerges. Do not over-fertilize, as excess nitrogen can reduce the intensity of fall foliage color
Eggshell powder topdressing：Crush dried eggshells into a fine powder; sprinkle 1–2 tbsp around the tree base in spring and fall, avoiding direct contact with the trunk to prevent pest attractionPruning
- Remove dead, damaged, or crossing branches in late winter or early spring before new growth begins
- Thin crowded inner branches to improve air circulation and light penetration to lower foliage
- Avoid heavy pruning, as it can disrupt the tree's natural canopy shape and reduce fall foliage display
