I must repot and stand it out, plant started to grow in my fridge.( i kept it in fridge, between 0 and +4 C, 32-38 F, in slightly wet perlite and gravel).
Segawai has the longest vegetativ- and shortest dormant - period among hardy cyps . Old growths dry completely in November, than I put it into the fridge, and despite of dark and cold it starts again in february.
