Best Oxygenating Pond Plants UK

Keen to bring new life to your outdoor pond? Oxygenating plants support fish, pollinators and all sorts of plants in a healthy and vibrant pond.

There are quite a lot to choose from and for the uninitiated it can be quite overwhelming to decide on which plants are best for a healthy pond.  

 

What is an oxygenating plant?

Besides the obvious benefits of improving the decorative qualities and providing a vital home for all kinds of creatures such as: insects, frogs newts, and baby fish, the main function of an oxygenating pond plant is to raise the oxygen levels of the water to a level of at least 6 ppm to support the life of the aquatic animals in the pond.

Moreover, this has the added benefit of not having to use some sort of oxygen pump, which can be problematic for fish and other animals.

Extra Tips for Using Oxygenating Pond Plants

1.Apart from aesthetically overcrowding the pond, too many oxygenating plants can be a bad for wildlife and compromise the amount of animals the pond can support

2.It’s a good idea to include more than one variety of oxygenating plant for improved bio-diversity in the pond.

3.When disposing of lant roots that are no longer needed, try to avoid the possibility of them reaching natural waterways.

4. A general rule to follow to achieve a good amount of oxygenating plants in your pond is 3-4 bunches per m².

5. Do not introduce too many oxygenating plants at once. Stick to one or two at a time and give them chance to establish before planting more.

6. Do not rely only on oxygenating plants to support wildlife – other plants such as marginals, floating, submergent etc.. all help to create the ideal environment for your pond to thrive.
