Pruning climbing roses

The benefits of pruning

Roses are among the most fascinating flowers and, not surprisingly, among the most loved all over the world. Their charm, however, is accompanied by the delicacy of these flowers, which require careful and regular care. Pruning is one of the needs of roses and, contrary to what one might think, it is a very important need and not to be underestimated, even in the case of climbing roses. Climbing roses have a wide development which, however, must be controlled in some way: not only to give a graceful and orderly shape to the plant, but also as an attention to the state of health. Pruning, in fact, allows climbing roses to develop branches with successive blooms thin enough to allow the filtering of air and sunlight: in this way the internal branches will not be suffocated by others and the best natural conditions will not be created for the proliferation of pests, which could kill the plant. Furthermore, eliminating the branches that are no longer productive and now dry is a way to preserve the plant and ensure that the new branches have all the nutrients they may need.

When to prune

Pruning has a beneficial effect on the plant only if it actually meets its needs: it is therefore necessary to take into account the needs of climbing roses, whose characteristics may vary depending on the species. In general, pruning will be carried out when the plant is preparing to resume its vegetative cycle, before flowering (or single flowering) of the summer. The best period, therefore, is that of early spring, at least for the most decisive pruning, which can be followed by small interventions to contain and control the shape of climbing roses. The type of intervention will also vary depending on the development and age of the plant: the most decisive pruning will be reserved for roses still in the growth phase, while older roses, which have already reached a good level of development, will have a slower growth and consequently less frequent and less invasive pruning will be necessary. Pruning can also be done in late winter: the important thing is to avoid pruning the plant during the vegetative awakening and flowering period, precisely in order not to compromise this phase of the rose’s life cycle, which can last until late autumn.

Pruning of climbing roses

To prune climbing rosesit is always necessary to keep in mind the reasons for which we are intervening: on the one hand to impose the desired shape on the climber, on the other hand to guarantee it maximum health and luxuriant flowering. It is therefore important to make cuts that have real benefits for the squad. First of all, pruning will allow you to eliminate the oldest and no longer productive branches, which take away energy from the plant. The branches will then be made less dense to allow air and light to pass even between the innermost ones, avoiding the creation of a microenvironment suitable for the proliferation of pests and parasites. Pruning can also be useful in case of localized presence of parasites, as long as it is sufficient to eradicate any organism present. In autumn the withered flowers can be cut, while in spring the intervention will be more decisive, cutting the suckers of the previous year, without intervening on the stems. The dead suckers and the tips of the stems compromised by the cold of the winter just passed will also have to be eliminated, which could no longer give life to any flowering or continue to develop.

Pruning climbing roses: Pruning of sarmentose roses

When it comes to pruning roses, it should be remembered that the generic indications must then be declined according to the specific needs of the individual species and varieties: there are many types of climbing plants and the different species of climbing roses, all characterized by different needs to know and indulge. Climbing roses but with slightly different characteristics are those defined as sarmentose, which differ in the presence of large bunches composed of small flowers, which create suggestive splashes of color. Unlike climbing roses, sarmental roses only bloom once a year. Since the characteristics of the plant vary, even the most suitable pruning conditions must be slightly different to meet the specific needs of the plant. Unlike climbing roses, sarmentose roses do not have perennial shoots and their development is more luxuriant: pruning will therefore be more radical to contain the growing foliage. Pruning takes place in autumn and all the shoots of the previous year must be removed. After flowering, even the suckers of the previous year will be eliminated, while the new ones will be able to develop by drawing all the necessary nourishment from the roots, to grow strong and resistant to parasitic attacks.
