Collectible rosebushes are those varieties which have already been on the market for years and which have achieved acclaim especially for their qualities; the new varieties created in more recent years are called new rosebushes; among these roses many are patented, that is they are protected because the patent forbids their reproduction to protect the rights of those who created them. The hybridizations between different rosebeds in order to create new types of roses require decades of patient work, great effort and very high costs. Among the varieties of modern roses, many present flowers with petals with light shades in the central part, and a more lively and intense shade towards the outside. Sometimes the petals are of a contrasting color on the reverse: a feature appreciated by many rose lovers. The rose is a bushy plant with erect branches and odorous flowers of various colors, the leaves are generally composed of three to five oval or spear shaped and of an intense and bright green. The rose, especially the red one, has always been the symbol of love and is therefore equated to the flowers of the earthly paradise of Adam and Eve. The cultivation of roses has taken place since ancient times when the five-petal one was produced, that is, a type of rose that blooms only in spring with a dark red or white color that is slightly pinkish at the end.
How to plant roses
Roses are planted in autumn or spring. They have an enlarged base at the base of the stem below the branches. This is the graft, which must remain above ground. When the so-called wild suckers, clear and thorny green branches, develop under the knot of the graft, they must be eradicated to prevent them from taking energy from the grafted rose bush. The most suitable soil for planting a rose bush is clayey, but not too compact, which must be worked in depth, enriched with mature manure or with nitrogen fertilizers and above all well drained. The best exposure of the plant is the south-east one; the roses prefer open spaces, well ventilated, an intense brightness but nevertheless tolerate a full sun exposure for the whole day especially in the summer season. Fertilizations are necessary during the vegetative period and at the moment of bud formation. As for the watering, the first after planting must be abundant; also afterwards it is advisable to administer water in considerable quantities whenever the soil on the surface appears dry. Periodically it is important to weed the soil at the foot of the rose bush to remove the dried one and adding a small amount to replace the removed one. During the winter it is important to have a good quantity of manure and leaves near the foot of the rose bushes, or fertilized peat tablets. Pruning keeps the rosebeds young: during this phase, the woody branches must be eliminated, in addition to the dry ones, while the more vigorous green shoots are left which depart from the base of the bushes of the bushes or from the base of the stem. Pruning is done before the vegetative restart depending on the climatic situations. In regions with a harsh winter climate (February / March) while in regions with a mild winter climate, it is advisable to do it at the end of the autumn season. It is also preferable to cut the flowers as soon as they wilt to avoid that, by maturing and forming the seed-bearing capsule, they take away vigor from the buds and the plant.
