In the summer we grow our Dendrobium nobile orchids in a 50% shade greenhouse at 80% humidity. We fertilize every two weeks with Cal Mag 15-5-15 from April through August and then stop the high nitrate fertilizer in order to harden off the new canes, which are staked for support. At Thanksgiving we move the nobiles (and the Dens in section Callista) into a nearly full sun greenhouse that drops to 53º at night, watering about every two weeks. This year, admittedly, a freaky warm year when all growth has been accelerated, they flowered in March.
The renowned growers and breeders of Dendrobium nobile hybrids at Yamamoto Dendrobiums have produced a terrific cheat sheet for growers. Don't forget to check out their gallery, which ought to get your pulse going!
