Prune the roses it is a delicate operation that requires some basic rules in order not to damage the plant, such as eliminating the wrong branches. In this regard, we will illustrate below chow to prune roses following some very useful indications.
When to prune roses, the right period
The right time to prune roses falls in February but also in summer. Let's see the different cases immediately.
Rose, winter pruning
In February therose they end their vegetative period to give space to the first buds. Precisely in this period of the year it is necessary to carry out the pruning of roses to encourage the production of new branches and consequently an abundant flowering.
Summer pruning of non-flowering roses
Non-remontant roses needsummer pruningwhich is carried out at the end of flowering. Therepruningof thenon-flowering rosesit is performed in order to prevent the plants from investing too much energy in the production of fruits.
Summer pruning of non-flowering plants does not have to be intense because the plant is in full vegetation and needs the leaves to perform the chlorophyll photosynthesis and sustain itself.
Roses for the production of rosehips
Theresummer pruning of roses It should NOT be done onnon-flowering roses chosen for the production of fruits, rose hips, very decorative! These fruits appear on the plants in early autumn and last until mid-winter, enlivening even the coldest season of the year.
Generally, who to choosenon-flowering rosesto take advantage of the decorative effect ofrose hipsmakes use of the cultivation of hybrids of different species of roses:
- Wrinkled rose
- Rosa hugonis

Summer pruning of remontant roses
After the firstflowering, remontant roses can be pruned in the short rest period which coincides with the hottest months of the year.
The re-flowering roses, in fact, after the first flowering, perform a short pause to bloom again when the temperatures start to get cooler.
Pruning is done to stimulate and reinvigorate the recovery: the tips that have already bloomed are cut. Go down until you find the second or third leaf of the apex already in bloom and cut just above a bud developed in the armpit.
Choose a bud facing outwards so that the new branch will develop outwards and the shrub will be able to maintain a more open and therefore more advantageous shape (better aeration of the plant mass, more light ..).
How to prune roses, winter pruning
The winter pruning sees a more drastic intervention than the summer one which focuses only on the flowering branches. Here are which branches to cut.
- Remove all weak or damaged branches.
- Shorten the stems of the new plants purchased in the nursery by about 30 cm.
- Eliminate the buds facing outwards, so that there are no intertwined branches.
- Make the cuts clearly about one cm from the gem.
- Cut the oldest branches at the base or at the point where they intersect with more vigorous jets, preferring instead the young ones, capable of holding a greater number of buds.
- Pruning in proportion to the size and age of the plant: 4-8 stems are left, a lower number in the more vigorous plants. However, with regard to climbing roses, the more vigorous the pruning, the more abundant the flowering will be.
Pruning of roses according to the plant
Each type of plant has its basic rules for pruning.
There pruning of climbing roses it must be done keeping the longer branches and cutting the weaker ones instead. It will also be necessary to remove all the leaves, on which pathogenic fungi often overwinter. It will then be necessary to fix the plant to a support favoring an arched development.
Old roses should be pruned only slightly. Better to avoid drastic interventions. On the contrary, bush roses need a little more drastic cuts.
Regarding the pruning / flowering ratio, remember the general rule:
- more pruning = larger flowers.
- Less pruning = more flowers but smaller.
The right scissors for pruning roses
The tools that are used for prune the roses are the garden shears for thin branches. The use of a saw is only necessary to cut any very double branches.
It is good to get a pair of gardening gloves when pruning. Another recommendation is to always have the tools clean and disinfected.
Apart from these recommendations, in reality, no special scissors are needed for the pruning of roses, just use sterilized and well-maintained scissors. Old scissors that are unable to provide clean cuts or that crush the branches of the shrub should be avoided.
If you really want to use a pair of scissors more suitable for the pruning of roses, all shrub and ornamental plants can be cut with ratchet scissors.
The ratchet system allows you to distribute the cutting effort: depending on the diameter of the branch, it is possible to activate the ratchet system and perform a clean cut with minimal effort.
A good pair of ratchet scissors (excellent value for money) can be found on Amazon for 8.05 euros and with free shipping. These are the Brüder ratchet scissors, they have an aluminum body to ensure maximum handling. Guarantees clean cuts without crushing.
