Cold temperatures affect water quality and the health of your plants and fish. A little preparation before winter prevents most of the problems it brings. Here is what we recommend.
Before winter sets in
- Clear out leaves and debris, including blanket weed, so they do not rot and release toxic gases. If leaves have built up on the bottom, scoop them out with a pond net.
- Trim plants around the pond to limit dead foliage falling in.
- Move water lilies to the deepest part of the pond.
- Service the pump and filter before any ice forms.
Once it gets cold
- Stop feeding your fish when the water temperature drops to 10°C.
- If ice forms on the surface, keep a hole open with a pond heater or de-icer so toxic gases can escape.
Treatments over winter
Algae treatments are rarely needed in winter. Fish treatments can be worth it, though, because fish are more prone to parasites and illness in the colder months. Popular options are API and Aquascape products.
