Pond Plants


1. What is an “oxygenating” plant?

As you may have guessed, an oxygenating plant is a pond plant that produces oxygen. In the case of pond plants, these plants “grow underwater and assimilate nutrients from the water through their leaves and they release oxygen. This why they form an important basis for the natural equilibrium in a pond, whereas they are extremely useful for keeping the water clear and healthy.” – Velda.com

These plants are fully submerged under water or partially submerged.


Oxygenation happens above and below the surface of your pond


2. How do pond plants keep ponds clean and healthy?

Oxygenating plants help keep ponds clean and healthy because they act as natural biological filters by absorbing harmful toxins, feeding on CO2, and returning oxygen into the pond’s ecosystem.

Perhaps you will remember learning about photosynthesis in Science class. Knowing about this process might help us understand how these plants help keep ponds clean and healthy.

Photosynthesis is the process in which plants transform sunlight, carbon dioxide, and water into sugars for the plant and oxygen for the rest of us! Land plants and pond plants function the same way, unless the plants don’t have leaves that reach the surface of the pond to find sunlight and absorb carbon dioxide. If this is the case, BiologyWise,com explains it this way:

But, what about the remaining plants that bear submerged leaves? In this aspect, carbon dioxide is obtained from water, which is released during respiration by fish. Also, decomposition of organic matter that takes place in the water ecosystem contributes to carbon dioxide production.

As pond plants absorb nutrients and carbon dioxide in the water (or above it if they are partially submerged), they prevent algae from getting at it, which means they cannot grow as fast and take over your pond. This reduces the algae in your pond, keeping the water clear and clean. The plants also help protect fish by providing necessary oxygen.


Oxygenating plants help to prevent green water caused by algae – and they clean the water for fish, too!
