Likely causes
Water stress
Most likelyHow to tell: The leaves turn yellow starting from the tips and moving downward. The soil feels dry or the water tray is empty.
What to do: Refill the water tray immediately and ensure the soil is fully saturated. Do not let the soil dry out again.
Sunburn
PossibleHow to tell: The yellowing appears in patches on the leaves facing the sun. The leaves may look bleached or scorched.
What to do: Keep the plant in full sun or very bright light, as it needs plenty of sun to stay healthy. If it was recently moved from a shadier spot or from indoors, let it get used to direct sun gradually over a week or two.

When to worry
A single yellow leaf at the very base of the plant is normal aging. If the yellowing is spreading across the whole plant, you need to act quickly.
Stopping it coming back
Keep the plant in a consistently wet environment and protect it from intense, direct midday sun. Consistency is the key to keeping the foliage green.
