Plant Needs
Sunlight
Full sun exposure is required for consistent fruiting; tolerate partial shade but will produce fewer fruits with reduced growth
Watering
Water deeply when the top 5–10 cm of soil is dry; avoid waterlogging to prevent root rot and fungal diseases
Temperature
Thrives in 18–28°C; tolerate brief light frosts (≥5°C) but prolonged cold temperatures will cause leaf drop and fruit damage

- Flower: Fragrant white five-petaled blossoms (orange blossoms) in dense clusters
- Fruit: Spherical to oblong orange citrus fruits with thick, textured peel and juicy, segmented flesh
Care Guide
Watering
Keep soil consistently moist during active growth and fruiting periods
Fertilization
Feed every 2–3 weeks with a balanced, slow-release fertilizer. Cease fertilization in late autumn to avoid stimulating new growth that is vulnerable to cold damage
Eggshell powder topdressing：Crush dried eggshells into a fine powder, sprinkle 1–2 tbsp around the base of the plant, and water thoroughly to release calcium into the soilPruning
- Remove dead, diseased, or crossing branches in late winter or early spring before new growth emerges
- Thin overcrowded inner branches to improve air circulation and light penetration for better fruiting
- Prune dwarf indoor cultivars to maintain a compact, manageable shape; avoid heavy pruning during fruiting seasons
