Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. You might also notice a damp, musty smell coming from the soil.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.
Underwatering
PossibleHow to tell: The leaves turn yellow and start to feel crispy or brittle at the edges. The soil will pull away from the sides of the pot.
What to do: Give the plant a thorough soak until water runs out of the bottom drainage holes. Maintain a consistent schedule of watering every 3 to 7 days to keep the soil evenly moist.

When to worry
It is normal for the oldest, lowest leaves to yellow and die back as the plant grows. Worry if the yellowing spreads rapidly to newer leaves or the whole plant.
Stopping it coming back
Keep the soil consistently moist but never waterlogged by checking the moisture level before every watering.
