Snow in the garden: harmful or protective for plants?

According to many meteorologists, the coming winter will be very cold and snowy. How does snow in the garden affect the plants? Many gardeners ask this. There are answers here.

Snow in the garden can be dangerous

It can be said that snow in the garden does not harm most plants. Especially light powder snow is not dangerous. However, if the snow is too wet and heavy, it can cause problems for some plants. Particularly sensitive plants such as roses or hydrangeas do not feel comfortable under too thick a blanket of snow and can be damaged. Evergreen trees such as cherry laurel or boxwood, but also bamboo, can break if the snow load is too great. You should therefore remove the snow from these plants regularly.

Snow is often good for the garden

Snow in the garden also has a fundamentally positive effect on many plants in the garden. The trees are the best example. When the snow on the branches thaws slightly during the day and freezes to ice at night, this thin layer of ice naturally protects the tree from wind and frost. But be careful: If there is too much heavy snow on the branches of trees, they can break under certain circumstances - especially older trees cannot always withstand the weight of the snow in some cases. Simply sweep the branches off with a broom.

The garden soil can also benefit from snow. The thermal conductivity of fresh snow is only about ten percent of that of snow-free, wet ground - that is why a snow-covered ground only gives off ten percent of the heat that would quickly be lost without the protective cover. Caution: You shouldn't walk around too much on snow-covered lawns - compacted snow provides a good basis for various fungal diseases.

On the perennial or vegetable patch, the snow can protect underlying tubers, roots or seeds from freezing. If there is no snow on the ground, cold and dry winter nights can quickly freeze the ground. In the worst case, the consequences are dead, frozen plants. Snow in the garden is therefore always a natural protection against the cold.
