Sub-soil biology and requirements
Perennials, flytraps die back during the winter months, enter dormancy, and rely on the few thick, black roots branching from the rhizome to survive cold climate. They return from the rhizome during spring, starting the season’s growth with a rosette of ground-hugging leaves and smaller traps.
Dionaea will clump, splitting growth points and sending up offshoots. You can separate individual plants as long as each one has a few roots to support the new plant. Use the water tray method to keep soil constantly moist (but not waterlogged) during growing months, and reduce watering during dormancy.
They take approximately four to five years to reach maturity, at which point they’ll be their maximum size, and send up flowering stalks in the spring.
