Before I froze them all a couple weeks ago I had maybe a dozen micranthum. I think the main predictor of blooming was the number of generations of line breeding. Some of the last generation from Orchid Inn would bloom twice a year... The oldest clones are the hardest to bloom. Same with armeniacum (or Roth, stonei, almost any species).
I kept mine in my unheated garage (by the south-facing window) for two or three months, the temperature is around 35-45F in the garage from Dec. to March. I still water them during the "rest" period but very lightly every 2 or 3 weeks..., and I believe "winter rest" is beneficial for micranthum and armeniacum.
Winter rest is just for these two species. You can keep the hybrids or the other parvi species slightly drier but not winter rest.
Mafate is a seasoned grower and he knows more than you think...
Makes a lot of sense.
) that I wasn't going to go from a fairly pronounced rest period to a fertilizer distribution like in the middle of the growing season. That said, I have only grown P. micranthum once in the past, about 30 years ago, at a time when I didn't know that this species needed a rest period, and I had failed in its cultivation. Today, access to information is much easier, and it is possible to benefit from the experiences of others to limit the risks, even if I know that what is valid for one is not systematically valid for another. That's why I preferred to ask. Thanks again for your help and have a good day.I would fertilize in the cooler temps. It was cut back along with water. Never seemed to have an effect on mine.Hello everyone, and thank you for your answers. I probably wasn't specific enough when I expressed myself, but it was quite obvious (in my head
Often down to 35F for armeniacum and micranthum in my garage, 40F is the average. I have done this(winter rest) for many years and the plants never have any problems. Just be sure they are dry/drier, water only lightly as needed.
