Sun: Full to part sun, and they require at least six hours of direct light to thrive.  We grow and keep ours under T8 grow lights indoors under a 14-hour light schedule. If after it has acclimated for a few weeks you're not seeing dew on the leaves, try giving it more light.

Water: Keep your Cape Sundew sitting in a tray with distilled, rain, or reverse osmosis water. Let the plant be constantly bottom-watered this way so that the soil is consistently moist.

Temperature: Cape Sundews are relatively hardy to different environments and temperatures. They do tend to like a small drop in  temperatures at night as they would experience in the outdoors naturally.

Soil: Recommended mix is four parts peat moss to one part perlite.  

Fertilizer: If your sundew won't be gorging itself on bugs, you can apply MaxSea fertilizer at a ratio of 1/4 teaspoon diluted in 1 gallon of water to the leaves of your plant once per month with a misting bottle.

Dormancy: Cape sundews do not need a dormancy period.
