Dend amabile and dend moshatum bloomless

[1kathleen]

I need help bring these two into bloom - both are fairly large - the amabile has lots of green leaves - 4 canes and looks healthy - lots of roots growing up out of pot - have kept fairly dry but not totally through winter -no growth of any kind for 6 months - the moshatum has about 10 leafeless canes and two with several leaves - have kept it dry also - naught on any new growth - both are in bright light in greenhouse with temps 63 or above..Please give me some clues...thanks so much
