In winter, the greenhouse in the garden often has to withstand large amounts of snow. When does this become a problem and how do you solve it?
The snowflakes float down from the sky as light as a feather in the cold season: but when millions of them land on the ground or roof, they quickly become a mass weighing several tons in the garden. Before their greenhouse collapses under the load, it's time to act. With our tips, your plants will be well protected even in winter.

It snows in winter – and not just once. In principle, with a thin layer of snow on the greenhouse, you do not have to worry. This melts away the sun on its own. Sometimes, however, their rays are not enough. According to garten.de, the rule here is: If the snow does not thaw within a day, you should clear it away. Not only is there a risk that the house will collapse – the plants inside will also suffer if the white masses prevent the light from entering. You already get too little of this in the dark season.

Without scratches: clearing snow on the greenhouse
Depending on how high the greenhouse is, snow can be easily pushed down with a broom (promotional link). If you are afraid of leaving scratches, you can also use special roof snow ploughs. These consist of a telescopic rod with a rubber lip attached to the end. A practical side effect is that they also remove the dirt from the roof that has accumulated there in spring and summer.

Which greenhouses are suitable for snow and winter?
As a general rule, even before the first flakes fall, gardeners should winterize their greenhouse and subject it to regular checks. In the event of cracks or even holes, you should react immediately, especially if they affect the roof tiles. Greenhouses made of polycarbon sheets are practical. These are robust and the plates can be easily replaced in case of doubt. Houses made of multi-skin triple slabs or multi-skin slabs also do not give way as quickly under snow loads. If you live in a region with a lot of snowfall, you are better off with them than with the glass version.
