How to Make a Terrarium Suitable for Carnivorous Plants


Carnivorous plants are plants that eat small insects, but still require plenty or light and sunlight like other plants. To keep a carnivorous plant in your home you must maintain a terrarium, which emulates the dry climates where carnivorous plants grow best. Different carnivorous plants require slightly different atmospheres in the terrarium. The best plant to start out with if you are new to maintaining a terrarium is the Venus Flytrap. You can purchase a Venus Flytrap at just about any local garden store and keep alive for a long time by keeping in a small terrarium.

Step 1

Purchase an 2.5 gallon aquarium. Don't purchase a larger aquarium or a heating lamp unless you are growing several carnivorous plants or your particular plant requires more heat than what is offered from sunlight. For example, if you have a sundew plant you should use a 60-watt lamp that goes over your terrarium and can be purchased at a pet store.

Step 2

Add 2 cups of sand and 2 cups of peat moss to your aquarium and then spread it out evenly with your hand so that you mix the sand and peat moss together. Never use potting soil to maintain your carnivorous plant. Add a 1/2 cup of distilled water evenly to the peat moss and sand mixture.

Step 3

Place your terrarium in a location that receives sunlight daily. Plant your carnivorous plant at least 1 inch deep in the peat moss and sand. Water the plant with a 1/2 cup of distilled water immediately after planting. Continue to add water whenever the sand and peat moss appears dry.

Step 4

Make sure that your aquarium has a tight lid that allows you to add food for your carnivorous plant easily. Consider taping down plastic around any open portions near the lid to help provide more humidity to your plant.

Step 5

Use a spray bottle to squirt the sides of the terrarium to keep it clean. Make sure that the water in the spray bottle is distilled water and not tap water. Spraying daily will help to keep the terrarium clean from insects that your plant eats, such as crickets.
