How Do You Make A Carnivorous Terrarium?
Some early naturalists, such as Carl Linnaeus, refused to accept the idea that a plant would purposefully eat an insect. However, according to National Geographic Magazine, a carnivorous plant called the Venus Fly Trap can sense an insect landing on it and will snap its leaves shut on the bug in approximately 1/10 of a second. Pitcher plants have a less dramatic trap; bugs fall into the tube-like leaves and the surface is too gooey to climb back out. To witness these plant marvels for yourself, build your own carnivorous terrarium. Place loose pebbles or small pieces of gravel on the bottom of the glass tank. Do not use alkali stones (such as marble or limestone). The Gardener’s Rake recommends using a gravel layer an inch deep. On top of the gravel, add a ½ inch layer of activated charcoal. Add a layer of sphagnum moss (about an inch deep). If you are planting sundews, Botanique recommends avoiding live sphagnum moss, as it may bury the sundews. Place a three-inch-thick layer of soil
