How to get Kalanchoe Blossfeldiana to re-bloom?
I have serveral full plants which I have had on my deck all summer. I never pinched them and I would not mind leaving them that way. I have read they take 14 hrs. of no light. One therefore has to cover them every day at about 6:00 P.M. and remove the dark cloth at 8:00 A.M. (if this is YOUR usual waking time!)for 5-6 weeks.
What is YOUR experience to get them to re-bloom? Where do you grow them? How low can the temperatures get?
