This roses category is extremely heterogeneous and contains all types of roses that for their growth can not be included with large flowers, floribunda roses, miniatures, creeping and ramblers.
By shrub, therefore, we mean a richly growing rosebush, which requires a precise space in the garden comparable to a Philadelphus, Spiraea and Viburnum.
All the Historical roses have a typical shrub growth, but there are also modern roses with developments attributable to this category.
What is shown below is an example of pruning on a modern shrub:
- eliminate dry, weak, too old and unproductive branches
- shorten all the side branches that bloomed the previous year at 2-3 buds
- eliminate old branches (twisted, too ramified and weakened) near new vigorous jets that can replace them by arrangement and size
- at the end of the pruninm, shorten the long new jets to 2/3 of the total length trying to maintain the harmonious appearance of the plant
- in order to have higher quality blooms with large flowers and compound shrubs, over 50% of the vegetation can be eliminated during the pruning phase
- in order to have a softer plant, not more than 35% of the vegetation can be eliminated from the blooming during the pruning phase
