It is still time to prune your shrubs, but you should not delay and carry out this essential operation for their good flowering in the coming days.
In any case, you must:
1- Cut back the stems in height
2- Remove dead wood and thin out the centre
3- Add manure or a rose fertiliser to nourish the bush
However, there is a crucial difference between old roses – varieties developed before the Second World War – and modern roses.
Modern roses, with long and often repeat flowering, bloom on the wood of the year; they should be pruned every year from November to March, outside of frost periods, to three buds.
Old roses bloom on aged wood; their flowering is shorter but very dense. They are pruned less frequently, every two to three years, at the end of winter.
