Plant Needs
Sunlight
Full sun to partial shade; full sun promotes optimal flowering and fruiting, while partial shade is tolerated in hotter regions
Watering
Water deeply once weekly during prolonged dry spells; established plants are drought-tolerant and require minimal supplemental watering
Temperature
Extremely cold-hardy to -30°C; tolerates hot summer temperatures up to 35°C in its native range
Characteristics
- Leaf: Oval to obovate, 2–7 cm long, serrated margins, turning red-purple in autumn
- Flower: Clusters of 5-petaled white flowers with a faint, sweet fragrance
- Fruit: Dark purple to black pomes, 6–10 mm in diameter, persistent into winter
- Stem/Bark: Thorny branches with gray-brown, fissured mature bark
Care Guide
Watering
Water deeply during dry spells to support new growth and berry development
Fertilization
Apply a balanced slow-release fertilizer once in early spring. Do not over-fertilize, as this can reduce flowering and fruiting
Eggshell powder topdressing：Crush dried eggshells into fine powder and sprinkle lightly around the base of the plant; water in to release nutrients graduallyPruning
- Remove dead, diseased, or crossing branches in late winter before new growth emerges
- Thin crowded branches to improve airflow and light penetration for better fruiting
- Trim to maintain desired shape after flowering, avoiding heavy pruning that reduces next year's blooms
