Colorful, exotic flowers and rich foliage enhance the beauty and health of virtually any pond. Selecting a variety of heights, textures and leaf shapes produces visual interest and depth, which contributes to a balanced look and ecosystem.
A well-planted pond is a great defense against green water conditions as aquatic plants deny algae of food and sunlight, thwarting growth. Aquatic plants offer a beautiful way to keep algae in check. They're an excellent source of natural filtration. After the bacteria in pond filters break down harmful pollutants into nitrates, plants absorb and remove them.
It's important to keep fast spreading varieties, like water hyacinths, in control because plants use oxygen during respiration at night. Fish need open space to access the pond surface, which is the primary source of oxygen. You might consider extending fishing line across the pond to cordon off water hyacinths to a specific corner of the pond to help prevent them from spreading or remove excess hyacinths from pond regularly.
