The southern beauty of the climbing rose is heat-loving and capricious. Growing it in temperate latitudes is not an easy task. But few plants can compete with it for the beauty of flowers and the elegance of the leaves. Gardeners are ready for much, if only to see the waterfalls of magnificent flowers, flowing from the walls, arches and arbours, which delight the look of climbing roses. Preparation for winter is a responsible exercise, without which these plants will freeze at the first serious frosts.
Prepare a sled in the summer
In a state of natural rest, roses do not enter as a result of a long selection of varieties. They meet the winter with leafy, which does not add to them frost resistance. They can easily withstand a short-term drop in temperature to -5 ...- 7 о С, but if a thaw occurs in winter, even at zero degrees they start to grow. This feature has both ordinary and climbing roses. Preparation for the winter for them should begin long before it occurs.
The right fertilizer
To shoots are well ripe and sufficiently strong, the plant is fertilized several times per season. The latest nitrogen fertilizing must be received no later than July. Since August they can not be introduced to prevent the growth of new foliage. What from late summer to fertilize the climbing roses? Preparation for the winter with the help of trace elements consists in the introduction of phosphorus and potassium.
Strengthening top dressing apply since the beginning of August. For the first time, a solution is introduced in which 20 g of superphosphate, 3 g of boric acid and 10 g of potassium sulfate are added to a bucket of water . Consumption - 10 liters per 4 m 2 .
The second feeding is done in a month. It can be root or be added to a sheet. 15 g of potassium sulfate and superphosphate are added to a bucket of water.
For foliar top dressing the concentration should be three times lower.
With the advent of autumn, excavations around the bushes stop: loosening, digging and watering. This is done in order not to awaken the sleeping buds in the fall, not to weaken the already delicate climbing roses.
Preparation for winter includes the complete removal of leaves before shelter. During the wintering period they decay and decay, which can lead to the development of diseases.
How to clip a clinging rose
The overwhelming number of varieties of flower buds are laid on the wintering shoots of last year. If you cut them in the fall, then there will be no flowering. However, during the season, the plant produces many powerful shoots up to 2-3 m in length, and putting them under cover is an impossible task. So it is absolutely necessary to remove a part of the weaves in autumn.
Major corrective works are carried out in the spring. In the autumn, the whips are cut out minimally, since it is not known how much the frosty rose and frost will suffer from the frost and obstruction . Pruning for the winter should be carried out taking into account the characteristics of the variety and thickening of the bush.
Cut out too young, weak and unseen shoots. Old retarded branches and unripe tops are removed. Shortened lateral shoots, departing from the main stems, and some conductors.
If the bush is heavily thickened, you can leave 11-12 perspective shoots, the rest cut. If the plant formed less than 10 shoots, they can not be removed.
Scrofulous roses include many species, and the degree of autumn pruning varies depending on the variety. It is better to leave the whip in the fall with a reserve in case of obstruction or freezing in the cold.
