梔子花零下10℃會被凍死。梔子花喜溫暖、濕潤的環(huán)境,適宜的生長溫度在18~22℃之間,越冬溫度需要控制在5~10℃。北方的梔子花不能露地過冬,需要將植株移動到溫室中養(yǎng)護,室溫保持在10~12℃為宜,避免低溫影響植株生長發(fā)育。

  梔子花喜濕,空氣濕度如低于70%,就會直接影響花芽分化和花蕾的成長,但過濕又會引起根爛枝枯,葉黃脫落的現(xiàn)象。除正常澆水外,應經(jīng)常用清水噴灑葉面及附近地面,適當增加空氣濕度。

  梔子花喜肥,宜施漚熟的豆餅、麻醬渣、花生麩等肥料,發(fā)酵腐熟后可呈酸性,但必須薄肥多施,切忌濃肥、生肥,冬眠期不施肥。種植不足三年的,切忌施人糞尿。

  給梔子花施肥是需要注意用量,施氮肥過多會造成枝粗、葉大、濃綠,但不開花。缺磷鉀肥時也會出現(xiàn)不開花或花蕾枯萎脫落現(xiàn)象。
