白兰花的越冬春管白兰花叶片柔厚青翠，花洁白，芳香若兰，是深受人们喜爱并随身佩带的香花之一；喜暖畏寒，因而越冬和早春管理是栽培白兰花的关键，要点如下：一、性畏寒，气温降至10℃时，即应入室，置向阳处，保持10℃至15℃温度，并注意最高温度不能超过20℃。二、停肥控水，盆土宁偏干，勿过湿，十天左右检查墒情一次。三、室内如有火炉或气温不稳定，可用塑料薄膜罩住树冠，以防烟薰尘染，并稳定温度及湿度，但应注意留通风口，以免湿度过大，空气闭塞，促使霉菌繁殖。四、花盆最好有固定的位置，不要经常移动，因白兰花对环境变换颇为敏感，尤其孕蕾后，易引起花蕾脱落。五、越冬期间保住革质碧绿的叶片不脱落是关系到来年开花好坏的关键所在，应随时观察：叶片发红、落叶和新芽萎缩，是浇水过多，引起烂根所致；叶片干边，说明缺水；叶片发皱，表示受寒，要逐步加温；叶片出现褐点、干尖、脱落，是室温过高所致，应对症及时采取补救措施。六、在中午气温较高时，应开窗使空气流通，但应注意不能使花直接受冷风袭击。七、立春前后，彻底摘去老叶一次，以促生新枝，仅留顶叶作观察用。有病植株不宜摘叶。八、清明后，谷雨前，气温稳定在10℃以上时，选气候晴朗之日出房，可先放在背风向阳处；要注意：出房过早易冻伤嫩梢幼叶，过迟则枝叶较大，叶薄枝弱，减低了对疾病的抵抗力。（来源：中国花卉报-02-22）
