Likely causes
Inconsistent Watering
Most likelyHow to tell: Leaves turn yellow and drop off when the soil fluctuates between being bone dry and soaking wet. The plant looks stressed and loses its vigor.
What to do: Establish a regular schedule by checking the soil every 2 to 5 days. Aim to keep the soil consistently moist but never waterlogged. Use a finger to test the soil depth before adding more water.
Too Much Direct Sun
PossibleHow to tell: The leaves look bleached or yellow, especially on the side facing the sun. This happens when the plant gets too much intense afternoon light.
What to do: Move your plant to a spot with bright, indirect light. If it is outside, provide some shade during the hottest part of the day. The plant prefers partial shade to full sun.
