Most likelyHow to tell: The soil smells swampy or sour, and the base of the stem is turning dark and soft. The plant may start to lean or collapse.
What to do: Repot the orchid into a fresh, well-draining mix. Trim away any black or mushy roots with sterilized scissors before replanting.
Overwatering
PossibleHow to tell: The leaves turn yellow and drop off while the soil remains constantly soggy. The roots lose their firm, white appearance.
What to do: Adjust your watering schedule to every 2 to 5 days. Ensure the pot has drainage holes and never leave it sitting in a saucer of water.
