I love orchids. What is fantastic about this magnificent species is that it's not as difficult to care for as one would think.
The lady in this video talks briefly about how to get orchids to re-bloom and she says to move it to a cool place, around 55 degrees at night. I read where, when the blooms of a spike fall off, to cut the spike near the top, at an angle, and that will prompt a new spike and eventually you will get new shoots from the original spike. That's exactly what happened with one of my phalaenopsis orchids. I have a new stalk, about 14 inches long and the buds are about to sprout.
