Likely causes
Root rot
Most likelyHow to tell: The leaves turn yellow and soft, often starting from the base of the pseudobulb. You might notice a sour smell coming from the pot.
What to do: Remove the plant from its pot and trim away any black or mushy roots with sterilized scissors. Repot into fresh orchid bark and wait a few days before watering again to let the roots heal.
Excessive light
Most likelyHow to tell: The leaves take on a pale, yellowish, or bleached appearance instead of a healthy olive green. This often happens if the plant is moved too quickly into a sunny window.
What to do: Move your orchid to a spot with bright, filtered light. Use a sheer curtain to diffuse harsh afternoon sun if the plant is in a south or west facing window.

When to worry
It is normal for the oldest leaf on a pseudobulb to yellow and drop as the plant ages. Be concerned if multiple leaves yellow at once or if the pseudobulbs themselves start to shrivel.
Stopping it coming back
Always let the potting medium dry out almost completely between waterings to keep the roots healthy. Ensure your pot has plenty of drainage holes to prevent standing water.

Questions people ask
- Should I cut off the yellow leaves?
- Yes, once a leaf is fully yellow, it will not turn green again. Use clean scissors to snip it off to keep the plant looking tidy.
- Can a yellow leaf recover?
- If the leaf is only slightly pale, adjusting the light might help it darken. If it is bright yellow or mushy, it is likely dying and cannot be saved.
