During the winter, there are several types of flowers that need care and protection from the cold and frost: roses and perennials, pseudo-rustic plants, shrubs and particularly fragile flowers. This protection varies from one plant to another and applies to the flowers themselves, the buds, leaves and roots. One must know the plant’s species to be able to maintain it properly, because there is no standard “one size fits all” treatment in gardening.

On this page, we’ll see how to successively carry out the anti-freezing treatment or flower protection from the cold, first for rose bushes, then for perennials and for shrubs, and finally for some types of very fragile flowers. Each flower having its own specificities, we must distinguish the type and the family while simultaneously determining the environment where it is located. Protecting them is relevant in order to be able to see them bloom again the following spring, or even during the winter for hardy flowers. This protection does not occur at the beginning of winter. This is very important since the flowers need to be given the opportunity to prepare naturally for the coming cold. Another precaution consists of never watering the plant during frost, because not only does the plant not need water during these periods, but the ice would “burn” it. As a final remark: dark protective plastics should be avoided.

Protecting roses and very fragile flowers

The easiest available way is the traditional method which is the mounding: the earth located around the base of the rose bush is gathered into a mound, to which leaves or potting soil are added. One can also proceed to mulching, that is to say, spreading straw or bark around the base of the plant. This allows the roots to retain heat better. However, do not forget to turn over the mulch from time to time to prevent the plant’s roots from rotting, especially when the rain is persistent. You can also resort to winter protection by simply covering the rose bush with a veil that will serve as a screen between the plant and frost, but that will however allow air and water to pass through. Bubble wrap and canvas are used to cover the pot in which the fragile flowers were planted. The container should be completely covered, with the flowering branches left free.

Protecting perennials and flowers in pots or on terraces

If flowers were planted in terra cotta pots, protect them from the winter cold winter by spreading a layer of polystyrene chips on the soil above the roots and cover the pot with a canvas or bubble wrap. You can buy these polystyrene chips in DIY and gardening stores. If they can be transported, it is preferable to bring the flowers in containers inside during the winter rather than leaving them outside. Otherwise, they can be covered up with a tarp or canvas. In regard to perennials, they only need a spring cleaning. For flowers, we can make a sort of small greenhouse with a flipped clay pot which will cover the plant and be used as its roof. Just let the plant breathe through small holes drilled in the pot cover. Mulching also helps to protect perennials well. When perennials burrow during the winter, remove all dead plants that are at the surface, and then lay down straw or leaves that are covered by a wire netting to let air and water pass through.

For bulbous plants, hardy plants and shrubs

The bulbs can be dug up and stored in a cool dry place, like a cellar for example, and remain there during the winter. They will be replanted in the spring, and will be even more reinvigorated. The same goes for tuberous plants. Not so hardy flowers can be mulched during winter to ensure their protection. When the winter looks like it’s going to be tough, a winter cover, which is very effective for this type of plant, is used right away. Regarding shrubs shake the snow that accumulates on branches from time to time; this prevents them from breaking under the weight of accumulated snow. Be careful to do so gently. Then we can mulch the base of the plant or, even better, use bark, leaves or wood chips.
