Considered one of the most Important groups of plants in the pond. An oxygenator is the term applied to a wide variety of fast growing plants. Originally so named because it was thought that they give out oxygen constantly though like all plants they give out oxygen during the day and use it up at night. Their primary benefit in a pond is their ability to grow rapidly, using nutrients that would otherwise be used by algae such as blanketweed. By occasionally thinning the oxygenators in the pond, a good healthy balance can be maintained.
Aquatic and marginal plants can grow vigorously. When thinning they should be disposed of carefully to avoid them colonizing and harming lakes, ponds, canals or natural waterways. Composting is considered the most suitable form of disposal.
How To Plant
Generally you will buy oxygenators in bunches. The best way to plant these is to anchor them in a pot with gravel and lower them into the water. Some oxygenators come in pots, such as the beautiful Water Violet. These are best replanted into larger baskets and lowered so the foliage is coming through the water surface.
