Most of the roses need to be pruned, a little trick of horyzon.
Bush roses with large flowers, grouped flowers or stem roses
March is the best time to prune your bush roses. You should leave 5 to 7 branches well distributed around the base. Give preference to young shoots and aerate the center of the rosebush by cutting off the oldest ones.
You must then cut these branches at about 15 cm from the ground in a bevel (the bevel oriented so that the water does not flow on the bud) just above an eye which goes towards the outside of the plant (5 mm above). Preferably leave three or five eyes, but if it is misdirected, cut to less. In general, three eyes are cut for young roses or bedding roses (Polyanthas and Floribundas) and five eyes for large flowered varieties (tea hybrids).
Remove weak or dead branches and cut back the others to 3 or 5 eyes. This will rejuvenate your plant. The cut should be clean, angled and about 1 cm away from the bud. The bud should be facing away from the plant.
For large flowered varieties and more vigorous roses, prune to four/five eyes.
In the fall, prune your roses at about 40 cm from the ground. This is simply an aesthetic pruning, to avoid seeing them without foliage all winter long.
Climbing and shrub roses
Also in March, you will cut back the branches by about a quarter of their length, above an outward facing eye. You will remove the dead and unhealthy branches, keeping only the vigorous wood. You can also remove older branches that are replaced by new growth.
For non-climbing roses, you should prune after they have flowered, in the fall.
Ground Cover Roses
Prune your ground cover roses according to the space available.
Miniature roses
Cut back miniature roses by one fifth and give them an elegant silhouette. Remove the small stems.
