Calathea Yellowing Leaves
All Calathea will have older leaves that will turn yellow and then drop off. Other leaves can also turn yellow and this problem can be caused by a number of factors.
- Overwatering – This causes root damage.
- Under watering – Yellowing can occur quickly if the plant is under watered. A good soaking will help it recover.
- Over fertilising – This can cause leaf burn.
- To much very hot sun – This can scorch the leaves Yellowing leaves generally do not recover, the new foliage will replace them eventually with proper care
