Building a garden pond

In short: A garden pond brings life into the garden, cools the surroundings, and provides habitat for amphibians, insects, and birds. Properly planning size, depth, and planting determines how stable the ecological balance will be later on.

In more detail: A pond with several depth zones and no fish stocking usually develops the most stable and clearest ecosystem, since plants and small organisms naturally clean the water.

In detail

• Choosing a location: A partially shaded spot without direct midday sun prevents excessive algae growth and overheating of the water.
• Depth zones: A shallow water zone, a marsh zone, and a deeper zone of at least 80 centimeters provide diversity and frost-free overwintering for animals.
• Pond liner or prefabricated basin: Liner ponds can be shaped individually, while prefabricated basins install faster but are less flexible in shape.
• Planting: Oxygenating plants like waterweed keep the water clear, while edge plants like reeds provide cover for animals.
• Starting without fish: A fish-free pond tends to attract more amphibians and stays ecologically more stable than a heavily stocked fish pond.
• Maintenance: Regularly removing fallen leaves in autumn prevents rot gases and excess nutrients in the water.
• Useful neighbors: A pond attracts birds and insects that also benefit the rest of the garden (bienenfreundlicher-garten, igel-im-garten-schuetzen).
