How to Make a Terrarium for a Venus Flytrap

By G.K. Bayne ; Updated September 21, 2017
Keep your Venus flytrap in its preferred humidity by building a terrarium.

When you get a Venus flytrap, chances are it came in a small pot with a plastic domed cover, as Venus flytraps prefer a hot, humid environment. If you do not have a terrarium at home to transplant the flytrap to, you can easily make one with common household items.

Repot the Venus Flytrap

Mix together equal amounts of peat or sphagnum moss and sand in a large bowl or bucket.

Fill the bottom 1 inch of a 6-inch pot with pebbles and the next 1/4 inch with activated charcoal.

Fill the remaining pot with the moss mixture. Dig a hole 2 inches deep and 2 inches wide in the center of the mixture. Water the mixture until water drains from the bottom of the pot.

Remove the Venus flytrap from the original pot. Shake any soil mixture gently from the roots.

Place the root ball of the Venus flytrap into the center of the dug hole and cover with additional moss and sand medium.

Make the Terrarium

Wash and rinse a 2-liter soda bottle. Remove the label and put the cap back on.

Cut the bottom one-third of the plastic bottle off using scissors or a razor knife.

Set the open end of the bottom over the Venus flytrap in the pot.

Press down on the top of the bottle to ensure that it is firmly in the pot.

Remove the cap of the bottle when water condensation begins appearing on the inside. This will allow fresh air into the terrarium.
