喜全日照且溫暖或涼爽環境，日照若不足植株容易衰弱罹病。不耐旱，尤其夏季高溫期要注意供水。介質使用排水良好的土壤，每季施用一次長效性綜合肥料。為保持樹型，可以隨時修剪會破壞樹型的徒長枝。繁殖使用扦插與空中壓條法。

The plant is fond of full sun and warm to cool environment, susceptible to weakening and disease if lacking of sun light. Not tolerant to drought, water use is particularly important in summer. Use well-drained soil, and apply long-active compound fertilizer once a season. Cut off water sprouts frequently to maintain the desirable tree shape. Propagated by cuttings and aerial layering.

適合單株種植或列植。因為忌燥熱，應種植於建築物東側或避免於西曬烈日之處。枝葉搓揉有檸檬般的香味，聞起來清新舒暢。但因為有小毒，僅可嗅聞而不適宜食用。

Suitable for single planting or row planting. Advised to plant on the east side of buildings or places away from harsh sun exposure. The branches and leaves have a fresh lemon-like scent when crushed. However, the plant is slightly poisonous, it’s for smelling and not edible.
