What to do if your pond freezes in winter?
If you find your pond frozen over one winter morning, avoid breaking the ice, as this can cause unnecessary stress for your fish.
While some people recommend pouring hot water onto the ice to remove the frozen layer, this can cause stress or serious injury to your fish, so should be avoided at all costs, instead we would recommend filling a plastic bottle with hot water and laying this on top of the ice to slowly melt an area.
To prevent your pond from freezing over, we recommend using a pond heater or aerator to maintain water circulation.
Should I cover my pond in winter?
Winter’s dropping temperatures can impact your fish's metabolism, causing them to become less active and seek shelter. This is especially true in the absence of aquatic plants, as fish have fewer areas to hide and seek safety.
This enhanced vulnerability for fish during winter makes them much more vulnerable to predators like herons. With this in mind, installing protective pond deterrents is essential in pond winter care. If you’re looking for ways to protect your fish, we recommend installing pond netting or heron deterrents in your pond during the winter months.
Do I need a pond heater in winter?
Pond heaters are an excellent way to prevent your pond from completely freezing during winter. They also help maintain the necessary gaseous exchange for your fish's health.
Brands like Superfish and Oase offer various models suitable for ponds of all sizes. The SuperFish Pond 150w Heater is safe to use even in harsh winter conditions.
Should I feed my fish in the winter?
Fish can typically handle colder months and have adapted to the British climate over the years. However, as pond owners, adjusting feeding habits during the colder months is important to protect our pond fish.
As the temperature drops, fish go through biological changes that cause their metabolism to slow down.
What's more, fish can take up to three days to digest food in the coldest months, so it is important to reduce their food intake while this occurs. We would recommend feeding wheatgerm food through the colder months stopping feeding altogether when water temperatures drop down to 4°C.
What month do you stop feeding pond fish?
Here in the UK, the feeding schedule for your pond fish heavily depends on the change in weather patterns. As winter sets in, we recommend you adjust your feeding schedule and feed type to a wheatgerm food from the end of October through the chilly months until around the end of March, as this is when your pond fish will most likely reduce their appetite.
Our latest guide covers everything you need to know about feeding pond fish during winter, including the best winter food for fish and how to ensure they stay healthy until spring.
Should I change my fish food in winter?
You should change your fish food in winter to more durable products like wheatgerm-based foods. These foods have a lower protein level, making them easier for fish to digest in colder waters (4°C to 10°C).
However, stopping feeding your fish altogether is essential when the water temperature drops below 4°C until spring arrives. This will help ensure the well-being of your fish during the colder months.
How to prepare Your pond plants for winter
Pond plants play a crucial role in maintaining water quality and providing shelter for fish. With this in mind, protecting them is essential in pond winter care.
To prepare your pond plants, remove dead foliage and floating debris towards the end of autumn. This will prevent oxygen depletion occurring from decaying leaves.
Most UK pond plants become dormant during winter. However, some pond plant varieties are evergreen, including reeds like equisetum hyemale and juncus.
Other pond plants, including primula Beesiana, caltha polypetela, and Sisyrinchium californicum, may retain their greenery, but their leaves may become damaged if temperatures remain below freezing for an extended period.
To protect your pond plants, ensure they are submerged in water at least 10 cm deep during the winter. This will shield your plants from most winter conditions.
Should I leave my pond pump running in winter?
Contrary to recommendations, there's no need to completely shut down your pond pump during the UK winter period.
Your biological filter houses beneficial bacteria that help improve your pond’s water quality, thus benefiting fish health during colder months. Shutting down your pond pump and filter for the winter would essentially halt this essential process, leading to the demise of these beneficial bacteria.
While these bacteria may become dormant in colder temperatures, supplying them with oxygen from the pond water will keep them alive until spring.
