The roses

Noble flower, cultivated for centuries throughout the Mediterranean area and in Asia, now present in gardens and parks all over the world, the rose is one of the favorite shrubs of gardening enthusiasts, thanks to the ease of cultivation and the beautiful flowers . In fact, the cultivation of roses in Europe is an ancient thing; in the past centuries the native species were cultivated for the beauty of the flowers, but also used to obtain the repzioso oil, with which ointments and perfumes were produced.

There are several dozen species of European origin, they are 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 growing season they do not bear flowers, or sometimes produce only a few. Although they have a certain gracefulness, botanical roses of European origin are quite different from the varieties that are grown for cut flowers; first of all they lack the re-flowering, and furthermore these roses are not particularly colored or perfumed; a typical example is the dog rose, delicate and soft.

Modern roses

Over decades of cultivation, botanists were able to encounter other rose species, with unique characteristics for the time: in India and China, the first hybridizers found very re-flowering rose species, with yellow flowers, with very double flowers or with swirled shape.

The crossings between European and Asian species, which took place from the 18th century onwards, first gave rise to ancient roses: varieties with large flowers, very fragrant and warm colors, often not very re-flowering; following modern roses: vigorous shrubs, with abundant blooms that last throughout the growing season, repeating continuously or renewing themselves every 30-35 days.

Modern roses are divided into some groupings, which distinguish the type of flowering, bearing of the shrub, or arrangement of the flowers; among the most appreciated we remember the hybrids of tea, that is the roses best sold as cut flowers, with turbinated flowers, which often bloom single on long erect stems; Floribunde roses are also very popular, producing large flowers gathered in small clusters; among the newest roses we remember the English roses, hybridized by David Austin in our days, which combine the re-flowering and robustness of the modern plant, with the charm of the shapes of ancient roses.

Grow roses

Most of the species and varieties of roses grown are rustic and easy to grow; they need a few tricks to obtain 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 bloom even in the shade, all the others must enjoy at least a few hours. of direct sun; if this were not the case we would obtain small, dull shrubs that produce little or no flowers.

We plant our roses possibly in the ground, so that the root system has the space to expand at will, using a good universal soil and at least 5-10 liters of mature manure, to be mixed with the soil of 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.

Cultivating the Rose - Rosa: Watering roses

Waterings are given when the soil is dry, from March to October; therefore, if the climate is rainy, roses do not need excessively regular watering, while during the summer months it is good to be vigilant, avoiding leaving the plant thirsty for prolonged periods of time. In general, roses tolerate drought and heat without problems, 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 fertilizer 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 fertilization, pruning is very important.
