Sundew Care: Humidity Acclimation, Water Levels, and Window Placement

A grower struggling with humidity shock on a sundew (likely Drosera capensis or similar) after poking large holes in a humidity dome seeks advice on recovery, optimal water levels, and window placement for transitioning the plant outdoors.

Recovering from Humidity Shock

After taping up the large gaps, the plant is slowly improving. Keep it in an east-facing window for now—this provides gentle morning light without the intense heat that domes can trap and amplify. Once the dome is completely removed, the plant should tolerate typical household conditions well.

Proper Water Tray Depth

Maintain water in the tray up to ¼ of the pot's depth. Use an oversized tray to ensure the soil stays consistently moist without waterlogging the crown. Sundews like wet feet but not submerged crowns.

Transitioning Outdoors

Before moving the plant outside (targeting March 20th), ensure it's fully acclimated to lower humidity and stable temperatures. An east window is a good intermediate step. Monitor for dew production and new growth as signs of readiness.

Key takeaway: gradual humidity reduction, consistent moisture, and appropriate light prevent shock and promote strong, dewy growth.
