There may even be quite a thick layer of snow on a flower bed. Its weight will certainly not harm perennials and bulbs wintering in the ground. The white cover also always serves green carpet plants, protecting them from the drying effects of the winter sun. A loose layer of snow protects lower shrubs and evergreen perennials well against the damaging effects of cold.
However, sticky and soaked snow quickly becomes heavy. In this form, it can harm trees and shrubs, especially always green, such as conifers. When snow alternately melts and freezes, a heavy, ice-snow crust forms, which bends the shoots to the ground, often breaking them off.Therefore, after heavy rainfall, you should free the shrubs from snow as soon as possible. To limit such situations, it is worth tying the extensive crowns of always green trees or shrubs with string in late autumn.
A thicker, longer-lasting layer of snow can damage clumps of ornamental grasses, the blades of which turn yellow due to poor oxygenation. A lawn that is often trampled during a thaw reacts in a similar way. If you want it to be in good shape in spring, you shouldn't walk on it unnecessarily in winter.
Small greenhouses are usually not able to withstand heavy loads. Snow must be removed from the windows also because it cuts off the access of daylight to plants.
