Why Shade Kills Sundew Dew: Light = Energy = Mucilage

Dry leaves on D. spatulata and D. adelae in shade? That's the problem.

The Science

Dew (mucilage) is a nectar secretion. Producing it takes massive energy → from photosynthesis → from sunlight. No sun = no dew.

D. spatulata: Full sun, heat tolerant.
D. adelae: Needs <80°F. Shelter in hot weather. Actually thrives on a bright indoor windowsill (our kitchen specimen: 2+ years, exploding).

Give them light, and the dew returns.

Carnivorous Plants: Repotting a Clumping Drosera spatulata; Recovering Drosera Adelae from Light Stress: Pruning Dead Growth and Adjusting Light Levels; Limestone Gravel on Drosera spatulata: Remove What You Can, Flood the Rest; Drosera spatulata Pale and Dewless? Move It Closer to the Lights; Transplanting Clustered Drosera Adelae: Do It Now or Wait; Drosera Adelae Normal Aging: Older Leaves Brown Naturally; Saving a Sunburned Drosera adelae: Radical Pruning and Recovery; Collecting and Sowing Drosera spatulata Seeds; Drosera adelae Pale and Brown Tips: Fertilizer in Perlite; Transitioning Drosera adelae from Terrarium to Open Culture
