栽培 Cultivation

全日照溫暖環境,介質須排水良好,春、夏季充足供水以促進枝條生長,春至秋每季施用一次長效性綜合肥料。冬季落葉期可修剪雜亂與長伸的枝條以控制植株大小。繁殖使用扦插、壓條、空中壓條法。

The plant grows well in full sun and warm environments and prefers soils with good drainage. Water regularly in spring and summer to promote the shoot growth, and apply long-term compound fertilizers once every season from spring to autumn. Remove cluttered and overlong branches to keep the desirable plant size during deciduous period in winter. Propagated by cuttings, layering, and air layering.

應用 Application

適合盆栽、籬笆、花架種植,下垂的枝條有柔美的姿態。初期枝條不具攀附能力,要用人工繫綁固定。枝條較脆,栽培位置要避免於風強處。如果修剪控制枝條長度,也可以作為灌木使用。市售盆栽多經過矮化劑處理,但隨藥劑失效後,枝條便會迅速伸長。

The spreading stems arching gracefully, the plant is suitably grown in pots, flower stand plantation, and as fences; the branchlets are not yet able to climb and need fixed by hand; the fragile branches are vulnerable to wind, choose the planting sites away from strong wind. They can also be planted as shrubs after the branches are pruned to control the length. The potted plants sold in the market are often treated with dwarfing agents, but the branches will quickly spread after the agent expires
