Noble flower, cultivated for centuries in the whole area of the Mediterranean and in Asia, now present in gardens and parks around the world, the rose is one of the favorite shrubs by gardening enthusiasts, thanks to the ease of cultivation and the beautiful flowers . In fact the cultivation of the rose in Europe is ancient; already in the past centuries the native species were cultivated for the beauty of the flowers, but also used to obtain the rich oil, with which ointments and perfumes were produced.
The species of European origin are a few dozen, they are of medium-sized shrubs, with very branched stems, which produce small white or pink flowers, with five petals, sometimes semi-double or double; these botanical species of rose bloom only in spring, for the rest of the vegetative season they do not bring flowers, or sometimes they produce only some. Although they have a certain grace, botanical roses of European origin are quite different from the varieties that are grown for cut flowers; first of all they lack the revival, and moreover these roses are not particularly colored or scented; a typical example is the delicate and soft dog rose.
Over the course of decades of cultivation, botanists have been able to meet other species of rose, with unique characteristics at the time: in India and China the first hybridisers have found species of highly re-flowering rose, with yellow flowers, with straddle flowers or swirled shape.
The crosses between the European and Asian species, which began in the eighteenth century, gave rise first to ancient roses: varieties with large flowers, very fragrant and with warm colors, often not very re-flowering; later on to modern roses: vigorous shrubs, with abundant blooms that go on throughout the vegetative season, repeating itself continuously or renewing itself every 30-35 days.
Modern roses are divided into several groups, which distinguish the type of flowering, bearing of the shrub, or arrangement of flowers; among the most appreciated we remember the hybrids of tea, or the most sold roses as cut flowers, with turbinate flowers, which often bloom single on long erect stems; also very appreciated are the floribunde roses, which produce large flowers gathered in small bunches; among the newest roses we remember the English roses, hybridized by David Austin in our days, which combine the revival and the robustness of the modern plant, with the charm of the shapes of ancient roses.
Most of the species and varieties of roses grown are rustic and easy to grow; they need few tricks to get healthy and luxuriant plants and abundant blooms.
The first rule to follow for those who intend to grow a rose is to place the plant in a sunny place, in fact only a few species (such as wrinkled roses or banksiae) can flower even in the shade, all the others must enjoy at least a few hours of direct sun; if it were not so we would get small dull shrubs that produce few or no flowers.
We place our roses in the ground if possible, so that the root system has the space to expand as desired, using a good universal soil and at least 5-10 liters of mature manure, to be mixed with the soil in the garden on the bottom of the hole.
If, on the other hand, we intend to grow our roses in pots, remember to use a large container, otherwise we will be forced to water our plant too often in August.
Grow Rose - Rose: Watering roses
Watering is given when the soil is dry, from March to October; therefore if the climate is rainy the roses do not need excessively regular watering, while during the summer months it is good to be careful, avoiding to leave the plant thirsty for prolonged periods of time. In general, roses easily tolerate drought and heat, even if very long periods without water cause the absence of flowering, and in extreme cases the defoliation of the plant.
To obtain abundant blooms it is then essential to supply the fertilizing plant, possibly in the form of manure, but if desired it is possible to replace the manure with a slow release granular fertilizer, to be supplied every 4.6 months; in addition to fertilizing, pruning is very important.
