In and around your garden pond, aquatic plants will not only be figurative. They also by their qualities contribute to the biological balance of your pond. But for each species to play its role, you must install each in the right place. This is why it is very important to choose the aquatic plants in your pond.

Choose the aquatic plants in your pond

The implantation of aquatic plants is an important moment in the installation of a garden pond. The ideal is to ask the question of which species of plants you want, at the very moment of the design of your project. In effect, it is the surface and the depth of your pond that will guide your choices.
Whatever your favorite, take plants adapted to your pond. And always use potting soil and fertilizers suitable for aquatic plants. You will avoid many disappointments.
2/3 of the water in your pond must remain in the open air. If the plants become too invasive, do not hesitate to limit them.

Marsh plants

They like their heads in the sun and their feet in the water (from 1 to 20 cm of water). You can plant them in pockets of soil that you have planned for the installation of your pond. If not, install them in baskets or coconut mats for the banks.
At this level, papyrus, iris, myosotis marsh, small moat or veronica, will be the refuge of frogs and toads. They also stabilize the banks of your pond.

Floating plants

As their name suggests, they float on the surface of the water and do not take root.
If you want to stay local, choose the water lens (it settles rather in the shade) or the water chestnut.
To introduce a bit of exoticism, adopt water hyacinth, water lettuce (pistia) or azole (it prefers shade). But in general, they do not like the cold and disappear in the winter. New ones must be introduced in the spring. Be careful, some are invasive and you will have to limit their growth.

These plants are high consumers of nitrates and therefore contribute to maintaining the good quality of water. In addition, they provide shading on the surface of the water. And they are a popular food for fish.

Submerged aquatic plants

These are plants whose the roots must always be in the water. You install them in pots placed at the bottom of the basin or in perforated baskets in coconut or plastic. To fill pots and baskets, always use aquatic potting and cover it with pozzolana to prevent the fish from uprooting the plants.

Depending on the species, you install your plants more or less deeply:

  • Plants for shallow water (10 to 20 cm): Calthas palustris or populate with large yellow flowers, family of ponderia with blue, pink or white flowers, cattails, water arums.
  • Plants for 20 to 40 cm of water: Cyperus longus or American papyrus, winter horsetail, water purse which is a remarkable oxygenating plant.
  • Plants for 40 to 60 cm: Aponogeton or water vanilla, white thalassis or Indian tapeworm, potamogeton crispus or lucens, valisneria.
  • Plants for deep water: The lotus, the lupine nuphar or yellow water lily, the excellent and excellent oxygenating plant that loses 30 cm to 1.50 m of water.

Water lilies and water lilies

What would be a basin without these beautiful plants so characteristic? In addition, both of them bring shade to the pool. A freshness that fish appreciate a lot!
The rhizome water lilies and water lilies must be immersed in standing water. These are hardy plants that can withstand the cold of winter without a problem. The superficial gel of the water of the basin does not disturb them.
Depending on the variety, they plant in 15 cm of water for dwarf species up to 1.20 m and more for larger ones.

Did you know? Often water lilies and water lilies are confused. The water lily is part of the family Nympheaceae. It is native to Western Europe and has small yellow flowers. The water lily is also part of the Nymphea family and has a more spectacular flowering of beautiful white, pink or red flowers.
