Twenty-eight thousand species. That is how many orchids exist on Earth.
Two dozen?
That’s all you need to keep your apartment from smelling like a compost heap.
Most people start with the Phalaenopsis (moth orchid). They are the golden retrievers of the orchid world. Forgiving. Resilient. They bloom if you barely look at them. Cattleya, Dendrobium, Cymbidium come next for those ready to graduate from beginner status. Once you get the hang of the humidity tricks?
Go crazy. Build a greenhouse.
The Light Trap
Light kills orchids faster than drought.
Most indoor setups are too dark. North-facing windows are basically black holes. West-facing?
Too hot.
Go east or south. Use grow lights. If it doesn’t feel slightly too bright, it isn’t enough.
Soil matters too. Real soil suffocates roots. Use bark. Unglazed terracotta pots. Let air flow. Fertilize at half-strength when they’re growing. Not when they’re dormant.
Here is the list. The good stuff.
