杜鹃花的花色各种各样，而且繁茂艳丽，具有较高的观赏价值，很多花友都会都想在自己家里种植杜鹃花，用美化居住环境，但是在养护杜鹃花的过程中很容易就出现杜鹃花叶子干枯、掉叶等现象，这是为什么呢?杜鹃花叶子干枯怎么办呢?

一、杜鹃花叶子干枯要及时光照浇水

许多花友在东北养殖杜鹃花会发现不久后叶子就会干枯掉叶，这个时候也不要着急，建议先检查杜鹃花的周围环境，杜鹃花叶子干枯大多都是温湿度问题，可以通过调节光照、浇水等手段来试试看，浇水也不能浇水多。

1、温湿度问题

杜鹃花对温湿度非常苛刻，它通常在15～30℃的气温下生长，湿度要求在60%以上，除此之外任何环境都不适合杜鹃花生存，不然会造成叶子干枯、掉叶、死亡等问题。

解决办法：如果杜鹃花叶子干枯是由温湿度问题造成，我们应该通过通过调节光照、浇水等手段，来调整环境的温湿度，使其保持在适合杜鹃花生长的环境，它的叶子就会恢复正常。

2、光照问题

杜鹃花属于日照植物，喜欢阳光，如果让它长期见不到阳光，一直让它处在一个昏暗的角落里，杜鹃花的叶子就干枯，甚至以后还会掉落，不过如果光照过强，或者长期处于光照之下，杜鹃花的叶子同样会出现这样的问题，那么杜鹃花叶子干枯怎么办呢?

解决办法：我们可以将杜鹃花转移到散光照射的地方，也可以依据季节进行调整，冬天的时候光可适度强些，等到天气渐渐回暖，逐渐升温，再移至半阴的地方。

3、浇水过多

每一种植物在浇水过多的情况下都会造成土中缺氧，使部分须根腐烂，阻碍植物正常呼吸和水分养分的吸收，引起叶子变黄脱落，杜鹃花也不例外，杜鹃花叶子干枯也有这方面的原因。

解决办法：如果杜鹃花由于浇水过多造成叶子干枯，我们应当将水及时倒掉或者更换盆土暂时停止施肥，并经常松土，使土壤通气良好。

4、施肥不当

杜鹃花是一个及其需要养分的植物，需要施肥来补充营养元素，如果长期没有施肥会造成土中氮素等营养元素缺乏，所杜鹃花营养不良从而干枯，但是如果施肥过量也不行，所以花友们平时要注意。

解决办法：对于这一种需要养分的植物，我们不能不施肥，如果施肥过量应当立即停止施肥，增加浇水量，使肥料从盆底排水孔流出，或立即倒盆，用水冲洗土坨后再重新栽入盆内。

5、土壤问题

大多数植物对于土壤是有一定要求的，像杜鹃花生长在南方、北方就特别要注意，北方多数地域土壤及水中含盐碱较多，南方红壤土偏酸，镁元素等易流失，这些都是造成杜鹃花叶子干枯的原因，你们这样的情况下杜鹃花叶子干枯怎么办呢?

解决办法：如果在北方发生这样的情况，我们可以栽植时要采用酸性土，生长期间经常浇矾肥水，而南方可以施钙镁磷肥或喷洒硫酸镁溶液来解决这个问题。
