There are many reasons for this, different reasons, there are differences in appearance. Now on the reasons and corrective methods are described as follows: water yellow basin soil water wet for a long time, resulting in soil hypoxia, so that part of the root decay, so water absorption, absorption capacity weakened, causing the top of flower shoots shrink, tender leaves yellow , Old leaves dark yellow.
