Which is the minimum t° when callista section dendrobiums go in dormancy period? Here now is around +12°C during the night and +19...22°C during day. The daytime temp is still ok but it worries me the nighttime temp. Should I still fertilize dendrobiums (densiflorum or griffithianum) and make the rest period from Halloween till Valentine's? I live in northern Italy and the winters here usually are cool and rainy. Night t is around +5° but can drop till 0 or even a bit below (but only in very cold winters like 2yrs ago). During the day usually is around +10. When I should bring the debdrobiums in? So far there are still outside catts, paphs and odontoglossums. But I'm worried about this +12 degrees during the night. Any advice appreciated.
