长寿花为景天科的一种多肉植物,叶片肥厚光亮,植朔矮化丛生,常绿。冬、春季开花,花期长达4个月之久。荏多,每枝可达数朵花。适宜作12~15厘米盆栽。性喜温暖气候,生长适宜温度18~30℃。以扦插繁殖为主,适宜扦插温度20~25℃。
盆栽适宜用排水性能好的基质,以泥炭土为主,适当添加珍珠岩或蛭石。培养土微酸性,pH值5.8~6.2。长寿花需肥量较低,前期可施氮:磷:钾为20:10:20的复合肥水溶液,每周施1次,后期可用氮:磷:钾为14:0:14的复合肥。长寿花对水分的需求较低,浇水时切忌叶片积水,否则会导致烂叶,因此入夜前必须使叶片保持干燥。
长寿花为短日照植物。暗期时数每天为14小时,经6周以上的短日照处理便可开花。利用此特点,可以对长寿花进行花期调控,以达到应节开花的目的。长寿花单株种植时,一般在定植后3~4周进行摘心,以促进分枝,从而获得较好的株型。在初现花蕾时,摘除部分花蕾,也可促进更多的花蕾形成。(推荐阅读:长寿花的繁殖方法)
