Creating a Humid Environment for Your Pitcher Plant
Pitcher Plants, or drosera, are an elaborate and colorful species of plants that create a tubular or globe shaped trap to snare and drown insects which they subsequently turn into fertilizer. Most often a vine, these carnivorous plants are found all over the Old World tropics.
These insectivorous plants do exceptionally well in indoor and outdoor gardens provided their special requirements are met including at least six hours of direct sunlight, a temperature range maintained according to the needs of the particular plant, a proper soil mixture and a humidity level that mimics their home range.
Most Pitcher Plants need a very high humidity level. Without the humidity, the plants will not form proper pitchers. They will usually abort or simply die back.
High humidity can be artificially created using pots or dishes of water placed near the plants, either outside or inside, and frequent misting with tepid water. During warm summer days, some gardeners hang potted Pitcher Plants under trees where the ground is kept moist.
Pitcher plants that are kept in pots or containers can also see their root structure exposed to humidity by wrapping a plastic bag around the outside of the receptacle.
It is also possible to place pitcher plants in terrariums to maintain humidity although this can sometimes have too big a cooling effect on them.
