Low Winter Humidity for Carnivorous Plants: Adaptation Over Humidification

A grower's home humidity drops to near zero in winter (80s in summer). Has round-leaf sundew, fork-leaf sundew, Nepenthes. Asks if plants survive or need intervention.

Humidity Is a Non-Issue

Carnivorous plants adapt to humidity changes if light, water, and temperature are correct. Customers in Arizona, Utah, New Mexico grow well in 15% humidity without special setups. One Arizona grower's cape sundew produced abundant dew at 15% humidity.

Focus on Fundamentals

Prioritize light, water, temperature. Minor winter imperfections from low humidity are seasonal — plants perk up in spring/summer.

Critical Note: Round-Leaf Sundew Is Temperate

Drosera rotundifolia (round-leaf) is temperate — best grown outdoors. It will drop leaves and go dormant in fall, emerging in spring. Care sheets: CobraPlant.com/caresheets (note: typo in original URL)
