杜鹃花的花色丰富多彩，深受人们喜爱。所以养杜鹃花的人也非常多，但是很多花友在养殖的过程中常会发生落叶的现象，杜鹃花掉叶子是怎么回事?浇水不当、植株对新环境的不适应等都是比较常见的原因，那么杜鹃花掉叶子怎么补救呢?

一、造成杜鹃花掉叶的5种原因

相信很多人在养殖杜鹃花的时候都会遇到掉叶子的问题，也有不少花友由于养护不当最后将杜鹃花养死的事情也常有发生，所以掌握杜鹃花的种植方法和注意事项就显得非常重要了。那么杜鹃花掉叶子是怎么回事呢?

1、温差过大

季节交替时如果温差过大，是杜鹃花掉叶子非常常见的原因。很多植物在冬天的时候常会有叶子干枯掉落现象，不用特别担心，只要不随便移动植株，等到了春天植株就会萌发出新叶。

2、环境变化

杜鹃花对新环境需要一定得适应期，出现少量落叶是一种植株自我保护的表现。此时的杜鹃花处于一个敏感期，如果盆土不是特别干就不要浇水施肥，摆在通风明亮的地方等植株慢慢适应后再进行正常养护。

3、浇水不当

浇水不当引起的杜鹃花掉叶子怎么补救呢?如何掌握杜鹃花的施肥和浇水是关键，杜鹃根系比较细，吸收水分比较缓慢，不能天天给它浇水，通常情况下是一个星期浇水一次，但是一定要浇透，盆底滴水就证明是浇透水了。

4、施肥不当

杜鹃花掉叶子是怎么回事的原因与施肥不当有关。杜鹃花施肥的3个时期:生长期、开花期、花谢后。生长期施稀薄腐熟饼肥为宜，可以勤施;开花前一个月施磷钾肥，促进多开花，此时肥料浓度要低，浓肥会让花蕾枯焦无法开花;在花谢后，施氮肥为主，促进枝叶生长。

5、盆土偏碱

自来水含碱，长期给杜鹃花浇自来水会使原本偏酸性的盆土呈碱性，造成植株水土不服，是杜鹃花掉叶子的一种原因。可以将自来水和醋按照100:1稀释后浇灌，让盆土恢复到酸性土质。
