How to Grow Your Own Carnivorous Plants


Carnivorous plants, such as the Venus fly trap, the pitcher plant and the sundew, are unique in that they eat insects to survive. Larger plants have been known to eat small reptiles, including frogs, toads and lizards. Most carnivorous plants are easy to grow as a houseplant, the Venus fly trap being the most popular. Carnivorous plants grow best in a terrarium and a simple model can be constructed easily at home.

Step 1

Mix together equal amounts of peat moss and white silica sand in a bucket or pail.

Step 2

Fill 6-inch growing pots with the peat/sand mixture.

Step 3

Place a 1/8-inch layer of peat moss over the top of the soil mixture.

Step 4

Water the peat mixture until water drains from the bottom of the pot.

Step 5

Press two to three carnivorous plant seeds into the peat moss.

Step 6

Cut the bottom out of a clean, 2-liter plastic bottle. The best place to cut is where the sides of the bottle meet the curved bottom. On some brands, there will be a black plastic base on the bottom of the bottle; cut the bottle directly above this base. Remove the label from the bottle.

Step 7

Place the open end of the bottle over the top of the 6-inch pot. Ensure that the cap is on the bottle and place the pot in a warm, sunny location. The bottle serves as the terrarium for the plant.

Step 8

Remove the bottle from the pot only to feed your plant monthly. Look for fruit flies, mealworms or other small insects to feed the plant. You can place the plant outdoors during the summer months for a day to feed naturally.
