Check these first

- Check if the pot has drainage holes.
- Feel the soil to see if it is waterlogged.
Likely causes
Overwatering
Most likelyHow to tell: The leaves feel mushy and the soil smells sour or moldy. You might see dark, soft roots if you gently pull the plant out.
What to do: Stop watering immediately and let the top inch of soil dry out. Repot the plant into a fresh, well draining orchid mix if the current soil is compacted or muddy.
Poor Drainage
PossibleHow to tell: Water pools at the bottom of the pot or the drainage holes are blocked. The plant looks wilted despite the soil being wet.
What to do: Ensure your pot has holes at the bottom and never let it sit in a saucer of standing water. Elevate the pot on pebbles if necessary to keep it away from excess water.
