My Dendrobiums are budding(don't know if they are flowers or keikis). I have them on the verandah and the recent temperature is around 15-19 celcius, however, it will drop to the lowest of 9 celcius in the next couple of days. So should I keep them out in the verandah or should I move them indoor? Will moving them around affect the flowering. Will that turn them into keikis? Someone please help me ? Thanks!
