栽培 Cultivation

喜好全日照環境;半日照也可生長,唯葉片排列較疏、開花數較少。根部忌積水,介質需排水良好。植株略具耐旱性,可待介質乾燥後才澆水。施肥可於春至秋季,每季施用一次長效性肥料。繁殖可以使用扦插法、嫁接法、空中壓條法、播種法。一般以扦插法為主,剪取成熟飽滿枝條30~50㎝長一段作插穗,全年均可進行。

It prefers growing in full-sun environment; it also manages to grow in partial sun, but with less leaves and flowers. It doesn’t like waterlogging in the root system, so well-drained medium is preferred. Moderately drought-tolerant, water only when the medium dries. Apply long-active fertilizers once in a season. Propagated by cuttings, grafting, air layering and seeds; cuttings are the main method by cutting the healthy mature branches about 30-50 cm long, which can be done throughout the year
