Sunlight
Full sun to partial shade; full sun supports optimal nut production, while partial shade tolerates woodland understory conditions
Watering
Water deeply when the top 5 cm of soil is dry; drought-tolerant once established, with reduced watering needs in mature plants
Temperature
Extremely cold-hardy to -30°C; withstands summer temperatures up to 35°C with adequate moisture

- Fruit: Edible hazelnuts enclosed in fuzzy, leafy bracts
Care Guide
Watering
Keep soil evenly moist during active growth and fruiting periods
Fertilization
Apply a balanced organic fertilizer once in early spring. Avoid high-nitrogen fertilizers that prioritize leaf growth over nut production
Banana peel compost tea：Compost banana peels for 2 weeks, steep in water at a 1:20 ratio for root drench; supports fruiting and overall plant health without chemical additivesPruning
- Thin crowded branches in late winter to improve air circulation and light penetration
- Remove dead, diseased, or damaged stems to encourage vigorous new growth
- Prune to maintain desired shape; avoid heavy pruning that reduces nut-bearing wood
