栽培 Cultivation

全日照溫暖至冷涼環境,因植株高大且質量重,栽培介質須有足夠重量以支撐植株,可使用砂質壤土、赤玉土混合碎石種植。定植後不宜過度澆水。每季施用一次長效性綜合肥料。繁殖使用播種、扦插法。

The plant enjoys full-sun, warm to cool environments. As the plant is tall and heavy, the medium soil must be firm enough to buttress the plant, preferably sandy loam or red earth soil mixed with gravels. Don’t water the plant too frequently after it’s grown in place. Apply long-active compound fertilizers once a season. Propagated by seeding and cutting.
