Aquatic plants, while providing the obvious aesthetic appeal to the water garden also serve the important role of helping to maintain the overall health and appearance of your pond.
Pond plants help purify the water by reducing nutrients, filtering out sediments, breaking down toxic compounds, and digesting unwanted substances.
Planting a diversity of species in the pond will ensure balanced filtration. Plants such as Cattails have short roots extending only 6-12 inches, where as Bulrushes can extend up to 36 inches allowing each to grab nutrients from different regions.
Rooted aquatic plants also help promote healthy bacteria populations. Without beneficial bacteria, nitrogen levels in the pond would become elevated, causing health problems in fish, diminished water quality, and promoting excess algae.
Certain plants, such as water hyacinth, are more capable than others at removing large amounts of algae-causing nutrients. Some waste water treatment facilities in warmer climates have even been designed specifically to use hyacinths.
Aquatic plants’ significance in filtration, their ability to provide better water quality, reduce maintenance and balance the ecosystem, all the while helping to create a more natural looking environment, are all reasons for you to consider the importance of aquatic plants for your pond.
