Location: Sundews make a great terrarium plant. Select an area that has bright indirect light. Morning sun is OK. Humidity is important to successfully growing a Sundew. Avoid humidity robbing drafts from heater and air conditioners. The ideal day temperature is between 45F to 85F degrees.
Watering: Drosera should not be allowed completely dry out! For best results use distilled water or rain water. Tap water with low salt content is acceptable provided water is allowed to stand overnight, to remove the chlorine. Sundews should not be allowed to sit in water.
Feeding: Sundews feed on aphids, and sphagnum gnats, and other soft-shelled insects. Look closely at the leaves and you will see the remains of insects that have been digested by the Sundew. Fertilizing with a 20-20-20 1/4 strength solution once a month is recommend to maintain vigor of the plant.
Transplanting: You can transplant your Drosera with sphagnum moss, with a layer of perlite or gravel at the bottom of terrarium or pot. You can grow in sand. You should transplant every two years, during any season.
Dormancy: It is best that Sundews get a rest period at least once every two years in the winter months. If your Sundew's leaves start turning black in the fall, allow it to go dormant. Store in a cool 40F-45F degree place until late February.
