Roses need to be protected from the cold and the winter sun
Prepare roses for the winter
Roses are plagued in the winter mainly by frost, sun and wind, with most types of roses with permanent frost itself have no problem - this is problematic only when the winter sun on mild days stimulates the sap flow and then drop the temperatures again sharply. As a result, the plant cells burst and there are sometimes serious damage, which can be seen especially in blackened shoots.
Preparation for the winter takes place already in midsummer
Although no one thinks of winter at 30 degrees in the shade, this is the right time to start preparing for the cold season. For this, however, you must first stop something, namely the fertilization of the heavy-eating roses. The plants should be fertilized for the last time at the end of June / latest in the middle of July. Subsequent fertilization only results in further shoots being formed, which, however, can no longer mature in time for winter and therefore are likely to freeze to death. Instead, between the middle and the end of August - but no later than - a final fertilization with a good potash fertilizer.
Especially important: protect roses from the winter sun
Roses become the sun in the winter far more dangerous than frost. On clear, sunny days in January or February, when the ground is frozen, water evaporates from the aboveground parts of the plant, but it can not be replaced by the roots in the frozen soil. Roses usually do not freeze in winter, but simply dry up. This phenomenon is also known as freeze-drying. A remedy is to cover the plants with fir or spruce, to protect the shoots from the strong sunlight.
Pile roses
By piling you protect your roses from both frost and the dehydrating winter sun. By this term, the gardener understands covering the plants with a 15 to 20 centimeters high mound, for which existing garden soil can be used as well as deposited compost. By the way, roses should not be cut in the fall!
Tips
In particular, high trunks are endangered in winter and therefore need special protection. Use fir or spruce, jute sacks and other breathable materials, but do not use plastic bags or bubble wrap, as they will only form condensation and cause mildew. Climbing roses, on the other hand, are effectively protected from the winter sun and cold winds with reed mats.
