My "culture" (like your "diet" is what you eat, not what you are supposed to eat), is pretty poor; but this thing flowers almost every yesr for me. It flowers right when temps come up, and frequently I lose buds from heat.
I grow in tightly-packed New Zealand Sphagnum in terra cotta. Would characterize winter nighttime lows as very cold: into the low 30's. Would characterize summer daytime highs as very hot: 100 degree afternoons are not uncommon. (Not while in flower.) Would characterize watering as moderate and seasonal: literature says to keep evenly moist, but I let run to the dry side when it's really cold. When in bud needs ample moisture and appreciates less than 60 degree diurnal temperature variation. ;-) Hot afternoons are exceptionally hard on the buds. Light is pretty bright; I shoot for apple-green Oncidiinae color foliage; for this that is Cattleya to Cymbidium light level. Guy I got it from grew with Miltoniopsis at about 60F min night temps; he flowered it better than I do. You can see some sunburned spots from when I have allowed it to get too dry. Although I am only seven miles from Monterey Bay and have some coastal influence, it's pretty dry here, and I don't have very high humidity.
I have been asked to set a capsule on this because it's "rare"; is it rare enough to do that? I had planned on repotting and dividing this plant this year.
