Treasure flower: yellow leaves, causes and fixes

Check these first

Stick your finger 3 inches into the soil to check for dampness.
Look for white, powdery spots on the undersides of the leaves.
Verify that your pot has functional drainage holes.

Likely causes

Overwatering
Most likely
How to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays damp for more than 14 days and may develop a sour smell.
What to do: Let the soil dry out completely for 2 to 3 weeks. Ensure your pot has drainage holes and never let the plant sit in a saucer of standing water.
Powdery Mildew
Possible
How to tell: This is less common for this plant, usually caused by poor air circulation or high humidity. You will see yellow patches on the leaves followed by a white, dusty fungal growth.
What to do: Improve airflow by spacing plants further apart or moving them to a breezier area. Wipe away the mildew with a damp cloth and avoid getting water on the leaves when you irrigate.

When to worry

It is normal for the very oldest, lowest leaves to yellow and die back as the plant grows. Be concerned if the yellowing is spreading rapidly across the entire plant.

Stopping it coming back

Stick to a strict watering schedule where you allow the top few inches of soil to dry out completely before adding more water.
