PSA: Orchids bloom again and last for years. I keep finding perfectly good orchids in the bio bin of my building. I don't understand why people throw live plants away like that. If you have an orchid, there are some basic steps to keep it healthy so it blooms again.
I have rescued three orchids from the bio bin already, one is currently blooming again. Please, stop throwing them away. Just remove the small brown peat plug they are sold with, add sphagnum moss to the pine bark they came with, and keep them in a humid, not soaked, state, with light reaching the roots. They bloom again, and they are kept for years.
