underwater plants Are an essential addition to any pond! Sufficient underwater plants that produce oxygen eliminates the need for a pump and filter. These plants purify the water and reduce heating from sunlight, which reduces algae growth. In addition, underwater plants foundations act as hiding places for fish in the event of imminent danger. Our hardy underwater plants omen directly from our own aquatic plant nursery and offer a 100% growth and flowering guarantee. For underwater plants we recommend a minimum of 10 to 12 individual plants per cubic meter (1,000 gallons of water) and 2 baskets of 4 plants per square meter. The exact amount depends on how quickly you want to balance the pond and your visual preferences.
Baskets underwater plants
underwater plants in baskets are suitable for shallow areas of the pond, often placed among marsh and riparian plants.
- Why. They provide a natural look by creating height differences between plants. They also help prevent algae in shallow wetlands.
- How much? The recommendation is to have at least 2 baskets of oxygen plants per 1 m².

- How many. It is recommended to have a minimum of 10 to 12 loose oxygen plants per 1,000 gallons of water.

Frequently asked questions about underwater plants
underwater plants should usually be placed at a depth of 30-60 cm below the surface of the water. However, consult the specific recommendations for the types of plants you have, as depth may vary.
In most cases underwater plants have enough nutrients from the pond. If you notice that growth is slowing or the plants look unhealthy, consider adding special pond plant food according to instructions.
Be sure to regularly inspect the plants for pests and diseases and remove any dead or affected leaves. Also remove dead plant parts to promote growth.
Yes, pruning underwater plants is often necessary to prevent excessive growth. Trim dead leaves and branches and thin the plants to promote air circulation and growth.
Many underwater plants are hardy and can survive in colder climates. They can become dormant during the winter months and grow again in the spring. Be sure to educate yourself on the winter hardiness of the specific plant species you have.
Underwater plant function
Water Treatment
underwater plants play a crucial role in purifying pond water. They absorb nutrients such as nitrogen and phosphate compounds, reducing algae blooms and keeping the water clear.
Oxygen production
underwater plants perform photosynthesis and produce oxygen as a byproduct. This oxygen is essential for fish and other aquatic organisms in the pond to breathe.
Shelter for fish
The dense leaf and stem tissue of underwater plants provides a natural hiding place for fish and juveniles. This helps protect them from predators and creates a balanced ecosystem.
Cooling of water
The leaves of underwater plants create shade and reduce warming of the water surface by sunlight. This helps maintain water temperatures at appropriate levels and reduces the likelihood of excessive algae growth.
Aesthetic value
underwater plants add beauty and diversity to the pond environment. They come in different shapes, sizes and colors, adding visual appeal to the pond.
Habitat for microorganisms
underwater plants provide a habitat for various microorganisms, such as bacteria and algae, which help break down organic material in the pond.
Support for the food chain
underwater plants form the base of the food chain in a pond. They provide food and habitat for small invertebrates, which in turn are food for fish and other predators.
In general, underwater plants is essential for a healthy and well-balanced pond, in which water quality is maintained and ecological balance is promoted.
