The tall North American pitcher plants of the genus Sarracenia and the infamous venus flytrap (Dionaea muscipula) are two of the more commonly grown carnivorous plants. They thrive in the bright, warm summer months but come autumn, they slow or completely stop growing and they may look dead. At this time it’s important to keep them from drying out, you can remove dead leaves, and if required, this is the time to repot them. In fact, the venus flytrap really benefits from being potted at least every second year. A mix of either pure sphagnum peat or peat and clean washed river sand is what they need. Don’t over pot them, as long as the plant is not busting out of the pot, it will burst back with new growth in spring.
The sundews or Drosera are another rewarding group. Charles Darwin, while studying the function of Drosera rotundifolia wrote “I care more about Drosera than the origin of all the species in the world”. They attract prey with glistening drops of sticky fluid atop tentacles which cover the leaves. Sundews are best kept in a bright position, sitting in a tray of water year round. They might slow in growth during winter but most will continue catching and eating insects. You can supplement their diet with a few small flakes of aquarium fish food to help keep them healthy. They enjoy the same potting mix as the venus flytrap and are just as happy in a small pot.
