栀子花叶子发黄干枯怎么办

一、减少浇水

原因:栀子花在养护时浇水过多,嫩叶就会暗淡无光泽、生长缓慢。老叶会发黄,逐渐枯萎。

解决办法:将花卉脱盆移置于避光通风处,等土干了以后在装回盆里。平时留意观察,如果发现叶稍发干、发枯,老叶枯黄甚至脱落,新叶没任何异样这时候是缺水的表现,应浇足水。

二、光照适中

原因:光照太强或太弱都会导致叶子发黄,干枯。长时间强光直射,叶片会有黄斑久而久之就会干枯。但是长时间放置在阴凉处,不见阳光,叶片会因得不到光照而脱落。

解决办法:长时间强光照射要及时移置于阴凉通风处,光弱的话可在傍晚阳光微弱时拿出来晒会太阳。建议放在窗户边养殖。

三、合理施肥

原因:种植栀子花时如果施的肥料浓度过大会引起新叶发黄,叶面不平整没光泽,老叶枯萎、脱落。
