This category of roses is extremely heterogeneous and contains all those types of roses that by development do not fall within climbing plants, bushes with large flowers, bunched roses, miniatures, creeping and ramblers .
By shrub we therefore mean a richly growing rose bush , which requires its own specific space in the garden comparable to a Philadelphus, Spiraea and Viburnum. All ancient roses have a typical shrub growth , but there are also modern roses with developments attributable to this category.
What follows is an example of pruning on a modern shrub rose bush :
- Eliminate dry, weak, too old and unproductive branches
- Shorten all side branches that have bloomed the previous year to 2-3 buds
- Eliminate old branches (twisted, too branched and weakened) in the vicinity of new vigorous jets capable of replacing them by arrangement and size
- At the end of the pruning, shorten the long new shoots to 2/3 of the total length trying to maintain the harmonious appearance of the plant
- To have higher quality blooms, with large flowers and compound shrubs, even more than 50% of the vegetation can be eliminated during the pruning phase
- In order to have a softer plant, no more than 35% of the vegetation can be removed from the early flowering in the pruning phase
