在养殖各种花草的过程中，总是会出现各种各样棘手的问题，尤其是对于没有任何养殖经验的新手来说，更是难上加难。许多花友们养殖的含笑花不仅没开花，叶子还变得枯萎了，那么含笑花叶子枯萎怎么办呢?应该怎么解决?

一、含笑花叶子枯萎怎么办

含笑花不仅开花的时候非常艳丽，它的花与叶都有着一定的观赏价值，但是许多花友们在养殖的过程当中都出现了叶子枯萎的现象，其实这些很明显都是由于养殖不当而造成的。不同方法引起的含笑花叶子枯萎有着不同的解决方法。

1、光照不足

含笑花叶子枯萎的原因很有可能就是由于阳光不足，含笑花性喜半阴，在弱阴下最利生长，但是也不是说完全不用光照，光照不足自然就会造成含笑花的叶子枯萎。

解决办法：要避免强烈阳光直射，夏天要注意遮阴。 秋末霜前移入温室，在10℃左右气温下越冬。

2、土壤通透不好

含笑花的养殖对土壤要求通透性好，如果采用的土壤通透性不好，粘性过高，会造成含笑根系难以呼吸，叶子掉落。

解决办法：养殖盆土最好用三分之一的草炭土或腐叶土与三分之二的细沙土混合，给含笑花最适合的生长环境。

3、浇水过多

含笑根部多为肉质，如果浇水过多会造成烂根，从而引发叶子枯萎，甚至发黄掉落。

解决办法：含笑浇水要注意要见干见湿，不能浇大水，也不能在阳光直晒下浇水。在生长期和开花期间需要大量水分，所以最好是每天浇一次水。

4、施肥不当

在含笑花生长发育期间，如果没有施正确的肥料，或者是施肥过勤或浓度过高，都会引起含笑花的叶子枯萎，甚至影响到含笑花不开花。关于含笑花不开花怎么办我们在之前已经了解过了。

解决办法：由于施肥不当引起的含笑花叶子枯萎怎么办，含笑花不喜肥，在长期良好的情况下，每月上一次干肥即可，过多肥料对于含笑花的生长发育也是不利的。

5、透风透气

含笑花长期待在一个环境里，长期都是不透气的，所以时间久了含笑花的叶子就会自然而然就变得枯萎甚至脱落，没有了生机。

解决办法：在室内养殖含笑花盆栽的时候，要经常把含笑花搬出去透风透气，不然会造成含笑花密不通风，不透气对于含笑花的生长发育也是非常不利的。

6、正常老化

含笑是一种常见的观花观叶植物，种植一段时间株植的新陈代谢也会造成老叶发黄掉落的情况。

解决办法：这是很正常的情况，所以并不用担心，只要做好日常养护，清理掉落的叶子，不要影响株植的通风透气就好。

二、含笑花盆栽病虫防治

1、介壳虫

含笑常发生介壳虫为害，吸取植株汁液，危害新梢及叶脉，通常多出现在枝叉处和叶的背面。

解决办法：可用小刷刷除，或用加水150倍的二十号石油乳剂喷杀。

2、煤污病

煤污病危害含笑叶子，不利于含笑生长。

解决办法：可用清水擦洗或喷加水500～1000倍的多菌灵水溶液进行防治。

3、叶枯病

叶枯病多发生于叶缘，叶上密生许多黑色小粒点，病情严重时，叶子枯死下落。

解决办法：清除病叶，发现病株及时喷施50{bf}托布津可湿性粉剂800~1000倍液。

通过以上的总结大家都知道了含笑花叶子枯萎怎么办，及其相对应的解决办法，希望花友们都能掌握正确的方式培育出美丽的含笑花!
