Using Permaculture Principles When Designing A Pond
Marginal plants, can be decorative as they can help blend the edges of the pond into the surrounding ground, but also provide shelter from the wind and the rain. Because they grow on the edges of the pond, they also serve as a barrier for fish and other aquatic animals from possible predators. Some examples of edible marginal plants are, Vietnamese Mint, stonecress, and rainbow parsley.
Oxygenating plants, have roots submerged in the soil, but their leaves unlike with the floating plants are completely submerged underwater. Oxygenators help keep the water clear by absorbing excess nutrients, as well as release oxygen which helps support aquatic life such as fish, and beneficial aquatic insects. Submerged plants must be carefully maintained as they can quickly dominate the habitat. Therefore it is important to remove excess plants, as well as cut the remaining plants back regularly. Some examples of of oxygenating plants, are water milfoil, hornwort, and water primrose.
Floating plants, float on the surface of the pond. They do not need soil, as the extract their nutrients from the water. Floating plants are extremely beneficial as they control algae. Floating plants control algae by restricting light, and filtering out excess nutrients. Some examples of floating plants, are duckweed, and water
