My bamboo (lucky) was sitting (in a room without heater or air conditioning). It is in a winter time where the temperature outside now drops to 15 F or -10 C. But the room temperature I think is around 15 C now.
It became like this after a day: The head goes down suddenly in a day, when I left home for a day.
How should I do to make the bamboo survives again? (It looks that the bottom still stays green.)
