A well-done preparation is the best way to prevent any winter damages. The roses should be planted deep enough and should be fed appropriately for the time of the year. Minor pruning helps to avoid dehydration.
In order to protect the roses against frost, the plants should be covered with soil (no peat, no mulch) during the grafting point at the end of November / beginning of December, when temperatures fall below zero. You may cover the mound with conifer branches.
Potted roses
Can be treated in the same way. The buckets should be protected additionally with special collars out of jute, liner, perforated bubble wrap or coconut mats. Choose a well-protected place. Potted roses should be watered during winter once in a while and please ensure sufficient drainage.Rose stems
Need special care against frost damages, due to their grafting point being
exposed at the end of the pile. Preferably fill the leafless top with wood-shavings or straw. Please pay special attention to protect the grafting point. Then wrap the top with jute, liner or intertwined conifer twigs. The pile itself only needs to be wrapped in very cold areas. Young rose stems can alternatively be bound to the ground to endure the winter in the soil.
