How to Water Drosera Capensis

Create a terrarium for your sundew to enclose the moisture and prevent constant evaporation. The Drosera should be planted in 2 parts peat and 1 part sand in a small pot. The sundew doesn't need a lot of root room, and the pot can just fit the root mass.

Place a bed of sphagnum moss in the bottom of the fish bowl. Put the potted sundew on top of the moss and water it until it is evenly moist. Some moisture will leak out of the drainage holes and saturate the moss, which is ideal. Keep the moss moist at all times to create a humid environment.

Water with only distilled water or rainwater. Tap water has too many harsh minerals and other additives. The Drosera is sensitive to chemicals, and tap water could harm the plant.

Wrap the top of the fishbowl with plastic wrap and poke a few holes in it. This will cause condensation and prevent the release of the moisture. Remove the plastic if more than occasional beading is seen on the interior of the bowl. You want slow, even condensation, not a rainfall of water. Let the container breathe by removing the plastic every other day for several hours to prevent mold.

Place the potted sundew on a plant saucer with a small layer of fine gravel and 1 inch of water. This is an alternative watering method. The plant will gradually take up the water, while the gravel keeps the roots from soaking in the moisture. The evaporation of the water also creates a humid ambiance around the plant. Drain the water and add fresh every two days.
