 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. |
