What is Hornwort?

Hornwort is a genus of aquatic plant that is native to many parts of the world including North America, Europe, Asia, Africa and Australia. It is a free-floating aquatic plant that typically grows in still and slow-moving bodies of water including lakes and ponds. Hornwort is a popular choice for aquariums, as it can provide shade and oxygenation. It is also known to help keep water clean and clear by absorbing nutrients.

What Does Hornwort Eat?

Hornwort is an autotrophic plant, meaning it produces its own food. While it does absorb some nutrients from the water it lives in, it primarily relies on photosynthesis for energy. It takes in sunlight, carbon dioxide and water and converts them into glucose and oxygen. This glucose is used for energy and cell growth, allowing the plant to thrive in its aquatic environment.

Does Hornwort Need Additional Nutrients?

Hornwort does not require additional nutrients to survive, but providing additional nutrients can have a positive effect on its health and growth. Hornwort is known to absorb nitrogen and phosphorus from the water, so adding fertilizers that contain these nutrients can be beneficial. Adding additional carbon dioxide to the water can also help, as it will provide more of a food source for the plant. Hornwort is also known to benefit from additional micronutrients such as iron and zinc, though it is important to avoid over-fertilization.

Can Hornwort Be Fed?

Hornwort is not typically fed, as it does not need additional nutrients to survive. However, Hornwort can be fed if desired. One way to do this is to add a liquid fertilizer directly to the water. This can be done every few weeks or as needed. It is important to only add small amounts of fertilizer, as too much can be harmful to the plant. Additionally, Hornwort can be fed with fish food, such as flakes or pellets. This should be done sparingly, as too much food can lead to an algae bloom.

Does Hornwort Need Light?

Hornwort needs light to grow and thrive, as it relies on photosynthesis to produce its food. It should be placed in an area where it can get at least 8 hours of direct sunlight per day. In an aquarium, Hornwort should be placed near the surface to ensure it gets enough light. If the aquarium does not get enough natural sunlight, artificial lighting can be used to supplement the light.

Can Hornwort Be Pruned?

Hornwort can be pruned if desired, though it is not necessary. Pruning should be done sparingly and carefully, as it can damage the plant. To prune, simply cut off the top portion of the plant with scissors or a sharp knife. This will help keep the plant from becoming too large and unruly. Pruning can also help to promote new growth.


Hornwort is a popular aquatic plant that is relatively easy to care for. It does not require additional nutrients and can be fed sparingly if desired. Hornwort does need light and should be placed in an area where it can get 8 hours of direct sunlight per day. Pruning can also be done if desired, though it should be done carefully to avoid damaging the plant. With proper care, Hornwort can be a great addition to any aquatic environment.
