Rescuing Venus Flytraps from a Portland Freeze

Laura's son received two small Venus flytraps for Christmas. One morning the soil was dry and plants droopy—she moved them to the fridge to thaw slowly and asked for further guidance.

Assessing Damage

Survival depends on how long they were frozen and dry simultaneously—that combination is most lethal. After thawing in the fridge, watch for leaf recovery. Unpotting to check the rhizome (bulb) is definitive: white and firm means alive; brown and mushy means dead.

Winter Protection Principles

Potted plants are effectively one hardiness zone less hardy than in-ground plants. Venus flytraps are Zone 8 in the ground (surviving ~10°F), but only Zone 9 in pots (~25°F for brief periods). In the Pacific Northwest, the easiest protection for a few pots is moving them into an unheated garage or shed during hard freezes. Shielding from wind and temperature swings is often sufficient.

At the nursery, all plants sit on the ground (not tables) and are covered with black plastic below 25°F. Detailed winterization techniques are covered in the Volume 1 DVD.
