In winter, not only animals hibernate. The pond also needs rest. If there are fish living in your pond, you must ensure that the entire surface of the water does not freeze. In this guide, you will learn what to look for when it comes to maintain ponds in winter. ⠀ WINTER POND MAINTENANCE IN NUTSHELL During the winter period, the garden pond requires almost no maintenance. But it is very important to secure it properly. Fish in the pond during winter Fish can be left in the pond for the winter without any problems – they do well in low temperatures. Although they can easily survive in the pond during the winter, it is imperative that the pond does not freeze completely. Only in this way will you provide the fish with an air supply. In winter, these animals do not need food: they reduce the activity of their digestive system and live on reserves set aside in summer and autumn. Protecting the pond from freezing A gentle way to protect a pond from freezing in light frost is to leave a piece of wood or a rubber ball in the water. In sub-zero temperatures, regularly pour hot water over these items to keep the cavity from freezing. Depending on the prevailing temperatures, it may be necessary to repeat this activity even several times a day. If your garden pond is shallow, you should, if necessary, move the fish to a warmer place during the winter, e.g. a special winter quarters. Depending on the number and size of the fish, you can overwinter them in a light-tight rainwater container that you can put in your garage or in a cool place in the basement. Water heaters and pumps The water heater is an effective solution for protecting ponds against freezing in the event of long-term frost. These devices work on the same principle as heaters. They turn on automatically in sub-zero temperatures, and turn off automatically when it gets warmer. Good quality water heaters are equipped with circulation pumps that ensure the circulation of water around the device. This serves even better protection against freezing.
