Likely causes
Light Shock
Most likelyHow to tell: Leaves begin to yellow or fall off shortly after moving the plant to a new location. This happens when the plant cannot adjust to a sudden change in light intensity.
What to do: Move the plant back to a spot with full, direct sun. Allow it to recover in that spot without moving it again.
Temperature Stress
PossibleHow to tell: Leaves drop suddenly when the plant is exposed to cold drafts or heat vents. The plant may look otherwise healthy but loses foliage quickly.
What to do: Keep your Celosia away from air conditioning vents, heaters, or drafty windows. Maintain a steady room temperature between 65 to 80 degrees.

When to worry

Stopping it coming back
