How to Use the Elodea Plant


Elodea is a very common freshwater plant, nicknamed the American Waterweed. It is a lightweight plant with long stems and relatively short leaves. Elodea plants are excellent for providing oxygen to aquatic ecosystems.

Indoor Aquariums

Step 1

Purchase several Elodea plants from a local pet or aquarium store. Make certain the plants purchased have a good set of roots.

Step 2

Place the roots of the Elodea plants in the gravel base of the aquarium to anchor them. Use one Elodea plant in each of the back corners to provide hiding spaces for smaller fish.

Step 3

Submerge another Elodea plant in the fish tank water for approximately 1 minute. Let go of the Elodea plant. Allow it to float in the aquarium water.

Outdoor Ponds

Step 1

Purchase approximately 1 dozen Elodea plants for your outdoor pond. You may also be able to find Elodea plants in local lakes and streams.

Step 2

Bury the roots of the Elodea plants in rocks and in the bottom material around the edges of the pond. Place the Elodea plants about 3 to 4 inches apart.

Step 3

Bury more Elodea plants in the center of the pond.

Step 4

Submerge a handful of Elodea plants in the pond for approximately 1 minute. Let go of the Elodea plants. Allow them to float and move about freely in the pond.

Tips and Warnings

  • Elodea plants self-propagate. You should plan on removing a handful of plants annually to prevent over-population in your pond.
