Likely causes
Overwatering
PossibleHow to tell: The leaves turn yellow and mushy, and the soil smells sour or swampy. The plant will look wilted even though the soil is wet.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil is waterlogged, repot the plant into fresh, well-draining soil and trim away any black, slimy roots.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil for a long time after watering. The pot may lack sufficient drainage holes, trapping excess moisture at the bottom.
What to do: Ensure your pot has drainage holes at the bottom. Add perlite or coarse sand to your soil mix to improve aeration and water flow.

When to worry
Worry if the stems become soft and brown at the base, as this indicates the rot has spread. If the plant is just drooping slightly before a scheduled watering, it likely just needs a drink.
Stopping it coming back
Always check the soil moisture before adding more water. Use a potting mix that allows water to drain freely rather than holding it like a sponge.
