Pruning rose: which branches to cut and when to prune roses. Useful tips to stimulate the plant to push back new vegetation and produce more abundant flowering.
How are roses pruned? We will find out together. There pruning of roses it must be performed with special attention that differ according to the different types of membership. In this article we will explain in detail how prune the roses and what are the precautions to consider in the case of particular rose bushes.
When pruning roses, the best time
Central-Southern Italy: from the end of November until the end of January.
Central-Northern Italy: from mid-February to the end of March.
This first pruning is done to keep the shrub plant healthy and tidy. By eliminating the weakest parts of the plant, you will protect it from mold, fungal diseases and parasites. A rose plant that carries with it fragile and weak parts, in fact, is more prone to suffer attacks from parasites.
Forprune the roses you have to act twice. The secondpink pruningit is performed in summer. It acts differently depending on the type ofrose plant(re-flowering or non-re-flowering).
Pink pruning: the first intervention
Before proceeding to pruning real (summer), in order to facilitate this important work, it is recommended to provide a thorough cleaning. The "cleaning" consists in removing dead branches, the weak ones and the branches that intersect each other, therefore, to begin:
- Remove dead, broken, sick and too old branches; cut them at the height of a bud facing the outside of the shrub or near healthy wood.
- Remove weak or too thin branches. To favor a few main and lush branches, it is better to sacrifice small excess branches.
- Remove the branches that intersect each other giving the rose bush a messy appearance. When several branches intersect, eliminate the one that seems weaker to you and those that are growing facing the center of the shrub: the foliage must receive light and air, so it must not be suffocated by a tangle of branches.
Climbing rose pruning
This phase must not be performed by those who are about to prune a climbing or sarmentose rose bush, for these roses it will be sufficient to tie the branches to the supports so that they do not get damaged by colliding with each other.
How to prune roses in the summer
For thenon-flowering roses it acts at the end of flowering. On non-remontant roses, a second pruning should be performed for shorten the brancheswho produced the flowers. It cuts just above a new jet. During what remains of the warm season, the plant will produce new branches thatthey will produce roseswith the flowering of the following year.
For theremontant roses, we act by eliminating only thewithered flowers: the stem is cut to 3-4 buds from the starting point of the year. By shortening the stem, the plant will produce new shoots floriferous.
How to practice rose pruning cut
The pruning cut must be made within 6-8 mm above a bud facing the outside of the bush and must be tilted downwards on the side opposite the bud.
When cutting a main branch, take care to cut the branch directly flush with the branch from which it originates, then clean the cutting surface with a sharp knife so as not to leave "burrs".
If the branch to be cut is large (with a diameter of at least 3-4 cm), use a clipper or a pruning saw; after cutting, brush the surface with healing putty.
Rose pruning: period
We recommend reading the in-depth study: When and how to prune roses.
In the article just reported, we saw the best time to prune certain types of roses; in particular we explained how to prune botanical roses, the pruning of roses from the park, the Floribunda rose, the tea hybrids and how to prune the rosebushes.
When to prune roses? The first pruning should be done in winter or at the end of winter. The second pruning is done in summer. In fact, summer pruning is essential for bothremontant rosesboth fornon-flowering roses.
Pruning of liana roses
Liana roses should almost never be pruned since their nature leads them to form very long branches that lean against those of trees or shrubs specially cultivated to support them, liana roses form beautiful flower garlands. On these shrubs we only intervene to contain them, should they develop excessively and become intrusive.
Pruning of miniature roses
For miniature rosebushes, pruning involves removing a few cm of the branch that brought flowers.
After seeinghow roses are prunedit is important to dedicate a brief parenthesis to fertilization. The reason? At the end of flowering, after pruning, the rose plants will have to push back new vegetation. Following summer pruning, it is advisable to administer fertilizer, preferably after abundant irrigation (with very moist soil).
When distributing the fertilizer, be generous. Generosity must not concern the quantity (always follow the instructions on the label) but the surface treated. The roots of roses, in fact, tend to grow much more than the foliage, they extend horizontally under the surface of the soil. The area that absorbs the most nutrients of a root (of any plant) is the newest one, therefore the most external ... take this factor into account when distributing the post-pruning fertilizer!
