栽培 Cultivation

吊竹草生命力強健,性喜高溫潮溼的環境,全日照或是半日照都能生長。 吊竹梅的蔓性莖可以沿著地面匍匐生長,每一莖節都能長出根來。一般使用扦插法繁殖。

It grows in full-sun or partial-sun environments and prefers high temperature and humidity; lacking of sunlight will cause water sprouts and dull leaf color. It’s not picky on soils, but prefers loose, fertile and well-drained soils. Propagated by cuttings, ramets or layering.
