I've been keeping six plants alive for about three years, succeeding at that--barely--but getting only 3 or 4 spikes with blooms during that time.
The greatest success has been with one of the Brassias (it grew a spike with a half-dozen blooms last year and currently has a spike with 9 blooms and a second spike found and freed up this morning; photo is in the Intro area).
One of the Phals bloomed once in three years, though it has tried to bloom more. The closed buds have fallen off the last couple spikes without opening.
The Laeliocattleya Trick or Treat has a few unhealthy looking leaves but hasn't done anything since I bought it in full bloom.
The Oncidium Golden Trident looks even worse, with shriveling PBs and just one or two leaves.
I took all of these orchids outside a couple weeks ago after reading on here that they should do better out there now that winter is gone. They got several good rains since as well as weekly fertilizer and almost daily artificial mistings and showers. I brought the blooming Brassia inside once the blooms opened and it is still doing well. The other Brassia appears healthy but refuses to bloom.
I'm assuming my growing conditions must favor the Brassias but it is obviously the wrong environment for the rest. My greenhouse serves double duty as a master bath (it's one of those Four Seasons rooms). The Phals have been placed on high shelves (too warm?) while the rest of them were together on a lower shelf. The room is on the southeast side of a 2 story house so its all shaded by the upper level after 2 or 3 PM and gets partial shade off and on during mornings and early afternoons (it's a heavily wooded site). Temperatures range from low 60F nights, low 70F days (in winter) to 70F nights and 80F days in summer. I've been monitoring humidity for several months and it is usually 50 to 60% unless I shower at night which brings it up to 70% or so. Oddly, showering during daylight hours has very little impact on humidity.
Two easy questions: (1) will the low-90s summer temps be too much for leaving the plants outside while they recover, and (B) what is wrong with my supposedly ideal indoor environment?
