Likely causes
Dehydration
Most likelyHow to tell: The soil around the base of the oak tree is bone dry. The plant loses its turgor pressure quickly without moisture.
What to do: Water the area around the host tree roots deeply. Ensure the soil stays consistently moist but not waterlogged.
Host disconnection
PossibleHow to tell: The plant is wilting despite adequate rainfall. This often happens if the root connection to the oak is severed.
What to do: Avoid digging or tilling near the base of the host tree. There is no way to manually reconnect the plant if the connection is lost.

Questions people ask
- Should I mist the plant to stop the drooping?
- Misting will not help because the plant relies on root moisture from the host, not humidity.
- Will it recover if I move it?
- No. Moving the plant will break its parasitic connection to the host and it will die.
