Maintenance

Maintain the pond

The floating and underwater plants will grow vigorously. There may be a need to thin them regularly.
To keep the pond healthy it is essential to maintain open water.
Leave plants that you remove from the pond lying on the side for a while so that any small creatures in them can make their back to the water.
The same applies to filament algae that you remove from the pond (which may also be necessary regularly).
If the water lilies develop too many leaves and hardly flower, it is time to divide their rhizomes and plant them anew.

In warm weather you need to top up your pond regularly, since the water evaporates quickly and the water level will drop even more rapidly if there are a lot of marginal plants in the pond water.
If possible, use mains water for this.
Ensure that the water jet never hits the pond directly and hard if there are fish in the pond.
