Garden roses do not survive harsh winters without shelter. In the middle lane, they begin to protect plantations from frost in mid-November. This should not be done in the past. The first November frosts will benefit the shrubs: they signal the plant to stop growing, and also have a tempering effect on the perennial
Preparatory work before sheltering shrubs
Before you start sheltering shrubs, you need to carry out sanitary work in your rose garden. Many causative agents of dangerous and infectious diseases hibernate on dry and fallen leaves or freeze until spring on non-lignified shoots in order to awaken again in the fall and continue their destructive activity. Therefore, it is imperative to remove the foliage in front of the shelter - not only those affected by white bloom, but also seemingly healthy greens.
Powdery mildew can winter not only on leaves but also on stems. Here she lives and develops in the form of a mycelium. All shoots affected by fungus, cancer must be removed. Cancer appears on the rose with light spots that surround the buds. The degree of the disease is determined by the color of the spot. When the stain darkens, acquires a red tint around the edge, nearby tissues begin to die off, forming deep wounds and capturing more and more healthy areas.
They also rake the fallen dry foliage from under the bushes. They can tell a lot about the health of a plant. So, downy mildew can be recognized by a gray bloom on the back of the leaf plate. If the fallen leaves are painted with dark, rounded spots, this is a symptom of black spot. In no case are such raw materials sent for composting. You should get rid of it. To protect your site from infection, it is better to burn these plant residues.
Roses hiding methods in the garden
The shelter of roses should not be over-the-top. Otherwise, this will lead to the creation of a microclimate favorable for the reproduction of pathogenic organisms. The materials must be breathable so that the bush does not overheat during thaws and on sunny days. For this, you can use earth, sand, spruce branches, sawdust. Polyethylene is not suitable for this purpose.
Frost protection technology for bush, climbing and standard roses has its own characteristics:
• Shrub plants should be covered with earth. The height of such a mound is about 20 cm. This is done in order to protect the base of the bush. And the tops of the shoots will be removed in the spring when pruning.
• Climbing perennials are removed from the supports for shelter. They, too, are thrown with earth only at the base. A non-woven insulating material is spread nearby, on which stems tied in sheaves are laid. This will prevent the plant from contacting the frozen ground, as well as the formation of additional roots on them with the arrival of spring heat. It is recommended to cover the stems with straw or spruce branches.
• Standard roses for shelter are also bent to the ground. It must be borne in mind that such varieties must always be inclined to the ground in one direction every year. Unlike other varieties, the crown of this perennial needs to be fixed to the ground so that it does not rise. It is pinned with pegs, and then covered with spruce branches, straw. The base must also be protected with a cover.
What difficulties arise when covering roses?
It is quite problematic to sprinkle bush roses that are grown in flower beds with earth. In this case, use other materials. Roses will be protected by a thick layer of mulch with sawdust and straw.
Climbing roses tend to grow strongly. And sometimes it is problematic to remove their tangled shoots from the supports. In order not to break branches, they resort to shelters directly on the trellises. To do this, use straw mats, spruce and pine branches.
The crowns of standard roses, which cannot be bent to the ground, are wrapped, maintaining their natural upright position. To do this, make a kind of sheaf of straw. It is recommended to additionally tie the stem and crown to the support if the shelter is too heavy.
