When to worry
A single lower leaf turning yellow is usually just natural aging. If multiple leaves turn yellow at once, it is a sign of a deeper health issue.
Stopping it coming back
Always allow the top layer of soil to dry out before watering again. Use a pot with good drainage to prevent water from pooling at the roots.
