About 150 different species and types of plants are cultivated. Additionally there are a few contracted nurseries that have specialised in certain sowing and cultivation technologies.
The definite focus is on cultivation of pond plants, but there are also large areas for perennials and specialised cultures for green roofs.
Because of the greater distance between plants the risk of illnesses is minimised. This way we can work without the use of pesticides.

Next to the greenhouse complex, to the left, are many shallow water basins and irrigation surfaces.

The stock of mother plants of many pond plants grow in the nursery as they would in nature.
Different underwater plants are extracted from the lake with a specially customised boat.
If the cold period is very long the underwater plants grow very slowly. Then we use divers.
The bulk of plants, however, is cultivated in special cultures, such as these primroses.
The sown cultures grow under protective liner tunnels and are automatically irrigated and fertilised.
Later, many plants for humid areas stand in irrigation areas, such as these ragged robins.
Perennial surfaces are covered with liner. This allows to catch the fertilised water and reuse it.
Typical pond plants stand in shallow water basins. Nets protect them against ducks.
Some underwater plants, such as these water violets are cultivated in their stabler above water form.
Plants are shipped from the greenhouse.
For each order labels are printed with all the important information.
At the same time plants are requested from the cultivation areas.
Underwater plants and water lilies meet in a shaded hall with a flowing basin.
About 20 workers assemble plants for the orders and package them for transport.
At this stage the plants are pre-sorted by planting area and have been separately packaged.
More than 20,000 plants leave the nursery in high season. Over 90% arrive at their destinations in 20 hours.
Land perennials grow clearly arranged on open air surfaces next to the greenhouses.
In spring the perennials are set on tables. Here visitors can choose for themselves.
On the other side of the greenhouse are the areas for the woody plants. Many can be supplied all year around in pots.
There are also special cultures of drought resistant plants that are used for green roofs.
The plant cultures are irrigated an fertilised via a system of pipes and conduits kilometres long.
