Oxygenating plants are fast-growing plants and will help keep your patio pond clean and reduce unwanted algae growth. They nurture the water and absorb excess nutrients from water through their leaves and then release oxygen into the water. This is why they create important support for the natural balance in a patio pond or water garden pond, beneficial for maintaining clean healthy water.
What oxygenating plants do you choose?
Not all oxygenator plants for ponds will generate oxygen throughout the season. For this reason, it is important to alternate and replace this species of plant. Water-crowfoot (Ranunculus aquatilis) is recommended for spring and winter, and waterweed, pondweed, hornwort (Ceratophyllum demersum) are preferred in summer and autumn. Hornwort is very dissimilar to the blue moneywort pond plant. Blue moneywort works well in small floating islands of the pond while hornwort grows underwater, and its main purpose is to keep the water clean and fresh. Other famous oxygen-producing plants are the water violet (Hotonia palustris) and the mare's tail (Hippuris Vulgaris).
Green water or fibrous algae growth in existing ponds that have excess nutrients and low oxygen. Planting oxygenated plants is not recommended. Algae absorbs all the CO2 available in the water, and due to this oxygenated plants will struggle to grow.
Placing oxygenating plants
Place the plants underwater in coarse sand, grit, clay pellets, or a particular growth substrate. In most environments, these plants will root straight down. This is inconvenient in most ponds, as the liner is at the bottom or a prefabricated pond has been used. Therefore, you are always advised to use pond baskets and separate the strands first. Place your oxygen-giving plants in a water garden pond that has good water quality, more minerals, and has sufficient CO2, so they'll keep the water fresh and algae-free. Opinions differ regarding the quantity of oxygen-delivering plants needed to keep clean water; however generally, gardeners plant five bundles per 250 gallons of water. Oxygenator plants for ponds require less care and maintenance than other water garden plants.
Why Do I Need Oxygenating Pond Plants?
Oxygen
These plants help provide vital fresh oxygen to the pond, which is necessary for all aquatic life and the survival of plants. Oxygen is the survival source of any pond, the richness of which maintains the health and well-being of the wildlife, fish, and even the beneficial microorganisms that live within the pond.
Water Filtration
These oxygenating plants, along with your filter and pump, help remove unnecessary additional nutrients such as nitrates from the pond. This, in turn, reduces algae growth which decreases the loading on the filter system. It not only enhances the appearance of the pond but also creates a positive atmosphere for your pond's flora and fauna to thrive.
Pond Decoration
Lastly, pond plants are a beautiful addition and provide useful shade throughout the summer and boost the appearance of your pond. Shade not only gives shelter for your aquatic animals but also helps stop algae growth. Some marshland plants and floating plants like the blue moneywort pond plant are also used to increase the landscape beauty of your water garden.
