Tinus Oberholzer from Plantae Orchids answers a reader’s question about keeping orchids alive.
A: Because there are so many orchid species that occur in a range of different habitats, they all have different needs. The plants you refer to are probably Phalaenopsis or Moth orchids, as they’re more readily available. These plants are very tropical and can’t stand cold winters. Many people tend to over-water them, killing them with kindness.
