They can tolerate brief periods of flooding and drying out. During the growing season, keep the planting medium constantly moist. During the winter, keep it just barely moist. Never water with anything but rain water. The natural range of Venus flytrap includes only Zones 7B and 8A, but introduced populations have thrived from zones 6 to 8B. Venus flytraps usually die back to the ground in winter, but they will remain evergreen in protected sites and warmer climates.
Fresh seeds germinate readily when sown on a suitable substrate.
Seedlings take 3-4 years to mature to flowering stage. Venus flytrap is easy to propagate from leaf cuttings taken in spring or summer and inserted in damp sand. Plants also can be divided. These plants require cool temperatures, a constantly moist substrate and a humid atmosphere. Grow in a cool greenhouse or in a terrarium in bright light.
