Reviving a Heat-Damaged Drosera Binata from Humidity Dome Baking

Humidity Dome in Full Sun Cooks the Plant

A D. binata from California Carnivores lost dew and browned after 6 hours direct sun in 90–95°F, kept in a half 2-liter bottle with 1-inch water. Over 2 weeks, all but 1–2 leaves browned. Seller claimed dormancy; grower doubts it.

Dome Created Lethal Heat Trap

D. binata tolerates full sun if acclimated. Sudden exposure caused leaf burn. The soda bottle dome in 90°F+ temps likely exceeded 100°F inside, shutting down growth. Sundews don’t need domes; they produce dew when light, moisture, and temperature are optimal.

Recovery Steps

Remove dome. Keep in saucer with water halfway up pot. Place indoors in bright south window to avoid heat. D. binata ssp. binata prefers cooler conditions; recovery time uncertain. Multifida tolerates heat best; dichotoma likes sunny, mild days with cool nights.

Good growing!
