Check these first
- Check the current season to see if it is time for dormancy.
- Feel the soil to see if it is soggy.
- Inspect the bulb for firmness.
Likely causes
Natural Dormancy
Most likelyHow to tell: The foliage yellows gradually as the weather warms in late spring. This is a normal part of the life cycle.
What to do: Stop watering entirely once the leaves begin to yellow. Allow the foliage to die back completely before removing it.
Overwatering
PossibleHow to tell: Leaves turn yellow and mushy while the soil remains wet for too long. This often happens if the drainage is poor.
What to do: Check that your pot has drainage holes. Reduce watering frequency to every 14 days and ensure the soil dries out between waterings.
