I have 3 different tolumnia. (popoki "mitzi', genting peach, and genting sunshine) All with good growth, get plenty of light, not over-watered, and seem happy. O yea, I've havn't got them to rebloom yet. I've only had them for just about a year. Shouldn't they be in bloom now? Is there anything like a temp. drop to initiate a spike? Any help appreciated. Thanks
