Almost all orchids, no matter the type, exhibit a growth pattern. Water all year long is one, providing a drier cooler winter rest is another. Yet some orchids go dormant every winter. Well not so much winter really. The cycle is often related to their native habitat.
The procedure I described above I learned about from a hobby grower in SW Florida. He was speaking at the Sanibel Orchid Society meeting about 8 or 9 years ago. You see Abigail, he had a passion for nobile type Dendrobiums. In most parts of the orchid world, Dendrobium nobile has a reputation for being a cool grower, especially at nights in the fall. It supposedly needed to cool nights to produce buds. Without cool nights you might not get flowers, fewer or none at all.
So many orchids will bloom just so-so under a lot of different conditions. However, where this fellow lived, cool nights are very hard to come by. But he figured out a method that worked for him. He reduced Deb. nobile to "trial and error".
