As with most aspects of your garden, the key lies in good, early preparation. You should start preparing your water feature for the winter before the temperature starts to drop below the freezing point.
Where possible, water features should be disassembled and stored in a shed or garage until the weather improves. However, this is not always possible, especially if you have cast stone fountains. In this case, you should begin by draining all of the water from the fountain before the first frost.
Once your water features are drained, remove the pump and clean it thoroughly before you store it for the winter. If needed, clean the remaining structure before it is covered.
For fountains, our experts recommend purchasing suitable covers. These covers are waterproof, so they stop moisture from getting into the stonework over the winter months. Many also come with a drawstring bottom. This addition stops smaller animals from using your water fountain as an unsuitable winter home.
If you cannot find such a cover, you can use blankets or towels to cover the fountain and sit in the tiers. It is imperative that you prevent the water from getting into the structure; frozen water within the structure can cause the fountain to crack and become unstable.

When temperatures plummet, you may need to step up your winter pond care methods to ward off winter kill. Frigid temperatures make it more difficult for you to keep an area of your pond ice-free, but the health and survival of your pond fish depend upon it. The following tips help you sustain your pond’s health during frigid periods.
Use A De-Icer
Properly install one of these devices before freezing temperatures hit. A de-icer helps keep a section of your pond open to allow oxygen and gas exchange. It does not, however, warm the water temperature of your pond. In order to maximize its efficiency, install it in the shallowest part of your pond and shelter it from the wind as best as possible. Some pond owners lay down a piece of plywood over a section of the pond bank where the de-icer resides. This helps keep warmth from escaping too quickly. Depending upon the size of the pond, its depth, and overall volume, more than one unit may be needed to keep a section clear.
Aerate
An aerator keeps your pond well oxygenated and can help keep a section of your pond open in the winter time. An aerator works under the premise that moving water resists freezing. When using an aerator, you must remember a few things. An aerator is capable of hyper-cooling your water, if used when air temps are below freezing. To keep this from happening the aerator should be kept in an insulated chamber (outside the pond) in order to pump in less frigid air, or the pump should be kept indoors with just the airline and airstones being used outdoors. This will allow warmer air to be pumped into the pond and eliminate the risk of hyper-cooling altogether. Keeping the pump in the insulated chamber or indoors will also aid in keeping condensation from forming in the airline and subsequently freezing, shutting down the aeration device altogether. You should also avoid installing airstones at the bottom of the pond. This will eliminate stirring up sediments and will prevent colder and warmer water layers from mixing and hyper-cooling your pond.
Thawing Out
If you are responding to a frozen pond emergency, you’ll need to first thaw a shallow section of your pond. To do this, use boiling water to melt the ice. Do not whack your ice with a chisel or any other tool, for the shock to your fish can kill them.
Remove Snow from the Pond Surface
Microscopic aquatic plants continue producing oxygen as long as light penetrates the ice. However, a blanket of snow over the ice prevents light penetration, making it impossible for the microscopic plants in your pond to produce oxygen. Combined with the decomposition of vegetation and fish waste, there may be insufficient oxygen for fish, causing them to suffocate. Snow removal, from at least a portion of your pond surface, will help reduce the likelihood of this happening.
Prepare For the Unexpected
During severe winter storms, power outages often result. Keep a plan in place for how you will power de-icers and aerators if this happens. Investing in a generator or a UPS (Uninterrupted Power Supply) will help protect the investment you’ve made in your pond. Depending on your pond’s fish load, a complete freeze can deplete the available oxygen in a relatively short time.
