As soon as the nights consistently bring frost, garden owners should prepare their rain barrels for winter. Failing to do so risks unnecessary and costly damage. However, with a few simple measures, the barrel can be reliably protected from freezing temperatures–and easily used again in the spring.
Avoid Frost Damage in the Rain Barrel with a Simple Trick
Those who want to collect rainwater even in the cold season can use a simple trick. In addition to special ice pressure pads, a piece of Styrofoam can also be used, advises the Consumer Advice Center NRW in a press release. These flexible materials absorb the pressure that occurs when water freezes, thereby preventing cracks in the barrel walls. Nevertheless, the water level should be as low as possible–the less water, the less pressure when freezing.
If an ice layer has already formed on the surface, caution is advised: It should be gently broken up. Otherwise, the ice acts like a solid seal, under which the water continues to expand–especially in barrels with vertical walls, this can lead to serious damage.
Protect Pipes and Accessories from Frost
Connected hoses and pipes must also be completely drained before winter. If water remains in the pipes, it can freeze and cause damage. In deeper or hard-to-reach pipes, remaining water can often be removed with compressed air from a compressor. It is also important to close the inlet to the barrel–for example, with a rainwater collector that has a winter setting.

Don’t Forget to Clean Before Storing
“This is also a good opportunity to thoroughly clean the barrel and remove deposits and leaves that have sunk to the bottom,” explains Hanna Vitz, a rainwater management consultant at the Consumer Advice Center NRW. Cleaning not only prevents unpleasant odors but also ensures that the barrel can be used immediately again in the spring.
Store the Barrel Properly
If you do not use your rain barrel in winter, it should be emptied as completely as possible and stored upside down in the garden–or better yet, placed in a protected area like a basement or garage. This keeps it safe from frost. The preparation pays off doubly: It is not only sustainable but also prevents costly repairs or the need for a new purchase next spring.
