- Inspect the base of the stem for dark or squishy spots.
Likely causes
Overwatering
Most likelyHow to tell: The base of the leaf or stem feels soft or mushy to the touch. The soil stays damp for more than three weeks.
What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, remove the plant from the pot, trim away black or slimy roots, and repot into fresh, well draining cactus mix.
Poor Drainage
PossibleHow to tell: Water sits at the bottom of the pot or the soil remains heavy and dense. The pot lacks holes at the bottom.
What to do: Ensure your pot has drainage holes at the bottom. Use a succulent or cactus soil mix that contains perlite or pumice to allow air to reach the roots.

When to worry
If the stem base is mushy or black, the plant is in serious danger. If only the tips of the roots are brown, you can often save it by adjusting your watering schedule.
Stopping it coming back
Only water your Hoya when the soil is bone dry, which usually takes 14 to 21 days. Always empty the saucer after watering so the plant never sits in standing water.
