Breaking Dormancy in Sarracenia purpurea with Light Cycle Adjustment

A grower in Puerto Rico induced dormancy in S. purpurea by reducing photoperiod to 9–10 hours (December). The plant stopped growing but retained red traps. Other plants fridge-dormant for 4 months are now waking.

Resume Growth by Extending Photoperiod

Increase light cycle to 14 hours after at least 2 months of short days. This works for all Sarracenia. They need less cold/dark dormancy than Venus flytraps or temperate sundews. In Hawaii, growers achieve success with a natural 2-month winter shortening.
