Fish in a pond under netting

How to cover and protect your pond for winter

Published: November 25, 2021 at 5:12 pm

Don't let your pond suffer through the winter months. A little protection will keep it pristine, cut down on routine maintenance, and keep your fish alive and well throughout the chill.

In winter your garden pond goes into hibernation, becoming less of garden focal point and a magnet for birds and insect life and more of a draw for leaves, twigs and all manner of garden debris. Covering your pond in winter months is therefore a good idea, and will keep it fresh and ready for the advent of spring and stop it being a cold and icy hazard to pets and small children during the darker days.

These simple interlocking floating shapes are a breeze to install in your pond. Simply place them on the surface of your pond and keep adding until the pond is full. They float side by side, finding their own space and interlocking to create a complete cover across the entire surface of your pond.

A real all-rounder, perfect for keeping anything in your garden dry and debris free while allowing light to pass through. Place over your pond – being careful not to allow it to sit on the surface as cutting off air supply to your water is never a good idea – and it forms a strong barrier preventing ingress from autumn and winter dirt and debris while allowing light to pass through to plants or fish below. It’s strong eyelets built into the sheet’s edge allow it to be securely fixed in place with pegs or ropes. Use across your pond in winter, an insulating curtain within your greenhouse or as protection for your fruit bearing trees and bushes come summer.

Not so much a pond cover as a clever device to STOP your pond from being covered… with ice. It’s a highly efficient floating heater, drawing a tiny amount of power to remain just warm enough to heat the water around it and discourage the formation of ice. Maintaining an ice hole is essential to support fish and aquatic life in the pond throughout the winter, while allowing oxygen and toxic gasses in the water to escape. One unit is able to keep ponds of up to 5000 litres with sufficient airflow. Or just add more units if you have a larger pond.

Weighty enough to prevent being flipped out of the water by the wind, but sturdy enough to stay in place once set, the natural movement of the water and its central vent will prevent ice from forming. No fuel, electricity or maintenance required.
