Lovely junceums, et al, Nelson!
I have a D. Adastra that I give a hard winter rest to. Its normal season for blooms is Feb-Mar. But I only ever get a single flower off the new growth.
Clearly my hard rest is too hard. A friend with a greenhouse said don't water it from late Oct to the first sign of growth in the spring. But she has good humidity, and in the winter my windowsill doesn't.
What would you recommend, Nelson, in a dry winter environment, to encourage more vigorous blooms come early spring? An occassional watering, misting, pointing out to it non-performers who recently croaked... Or would it be more fert during the growing cycle, which is now past? I tried to do that more this year.
