I had never had an orchid before this time last year. It bloomed beautifully and then went dormant. I did absolutely nothing except to give it the three prescribed "ice cubes" per week. When the stem started to die off, I googled orchids and learned to cleanly cut off the stem and wait. After many moons of waiting, and one snapped stem incident, "Miss Patience" danced into the light.
I have no idea what the longevity of the orchid is, but will keep on doing the same thing and possibly add a little fertilizer in the coming year. It's such a pleasant surprise to see the blooms again.
