Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy. The soil stays soggy for days after watering.
What to do: Allow the excess water to drain completely after each watering. Ensure your pot has drainage holes and use a well draining potting mix.
Nutrient Deficiency
PossibleHow to tell: Older leaves turn yellow while the plant looks generally pale. This happens if the plant has been in the same soil for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Do not fertilize if the plant is struggling.

Stopping it coming back
Only water when the soil surface feels slightly dry and ensure the pot drains well.
