Fungus gnats. Overloved cacti. Fiddle fig failures. $20,000 specimens. It’s house plants — and it’s wild, folks. Widely beloved author, artist, house plant expert and Domestic Phytologist Tyler Thrasher joins to talk about root rot, what to grow in a dark basement, the rarest plants in the world, the punishments for poaching them, grow lights for people and plants, houseplant ethics, how to keep your cats from taking whizzes in them, if you should name your plants, how often to repot them, how to keep an orchid out of your trash can, pet-safe, plants, if one should use their own surplus blood to feed them, and what botany crimes I have committed against my own plants.
