Likely causes
Temperature Stress
PossibleHow to tell: Leaves turn yellow or brown before falling off, often after a cold draft or heat blast. You might notice the plant looks wilted despite the soil being moist.
What to do: Move the plant away from air conditioning vents, heaters, or drafty doors. Keep the room temperature between 65 to 80 degrees Fahrenheit for best results.
Severe Root Rot
PossibleHow to tell: The stems become mushy at the base and leaves drop rapidly. If you gently pull on a leaf, it may come off with very little resistance.
What to do: Remove the plant from its pot and inspect the roots for dark, slimy, or foul smelling sections. Trim away the dead roots with sterilized scissors and repot in fresh, well draining soil.

Questions people ask
- Should I be worried about one leaf falling off?
- If it is an old leaf at the bottom of the vine, it is just natural aging. If it is a new leaf or multiple leaves, check your watering habits.
- Can low light cause leaf drop?
- Yes, if the plant is in a dark corner, it will eventually shed leaves because it cannot support them. Move it to a spot with bright, indirect light.
