Gorgeous roses bloom and blossom - and only for this reason they have been planted. Thus, they do so diligently, they must be continuously cut in the summer. The execution of the maintenance-cut for grafted roses is just as simple as its reason. But it should be noted that there are many other kinds of roses. Climbing roses, shrub roses, wild roses and so on. These have partly different properties. But recognizing the basic principles is the most important, because a clever gardener not only sharpens his shears, but mainly his mind.
All plants have a common aim - they want to reproduce themselves. Most of them do this by forming a flower that produces a fruit, and in the fruit new seeds. Even for the grafted rose is a rose hip, but it is good for nothing. If you bring to germinate their seeds, you would obtain a wild specimen, which shows no resemblance to the original plant. Neither in color, nor flower shape nor in the number of flowers and leaves is a match to be expected.
However, the formation of a fruit consumes a lot of energy that reduces the flowering strength. Therefore, old flowers have to be cut off immediately, before any fruit can arise. And the measurable effect is that the rose plant is forced to grow new flowers elsewhere. Thus they can be kept on blooming until late fall.
The right cutting position is below the old flower just above the next five-leaved shoot. Should this point not be so low that still a long stem comes out of the rose bush, cut at a lower level until the juice balance is reached. That new buds exceed the juice balance, often can not be avoided. But that is not bad, because these exposed shoots will therefore present in their full beauty.
There are other reasons for the "nursing cut" at roses. Some varieties bring out too heavy flower nest, which could cause the breaking of the stem by its own weight. Before the next wind or rain comes up, you should therefore cut out the old flowers on it.
The other reason is illness or infection. If not treated with chemical agents, these shoots must be removed immediately. They should be cut generously, so that only healthy parts of the branch is remaining. The infected cuts should not be put to the compost, because particularly fungal deseases might spread again. The scissors must be disinfected to prevent the infection of other roses at the next cut.
Finally all wild shoots are removed, as soon as they occur in the summer. Wild rose shoots can be easily recognized because they have at least 7-9 leaves, instead of (mostly) 5 at a grafted rose. This is the most important identifying feature. In addition, the wild drives usually have smaller leaves than the parent plant and are usually somewhat lighter colored. These wild shoots sprout always below the bud union or from the upper part of the root. Cut them radically back as deep as possible, otherwise they will come back.
Garten trick :
Grafted roses generally have five unpaired pinnate leaves (ie, the last leaf sits alone at the top ). Directly below a flower it can be just 3 leaves.
Wild shoots have at least 7 leaves and sprout from the base of a rose, which usually has only five-leaved shoots. Wild or ground-cover roses can also have shoots with more than 7 leaves!
