Climbing rose — ‘Compassion’. Pruning of existing roses is generally done from mid-November to the end of January, which used to be very complicated as different pruning instructions were advocated. Some people advocate digging up the poor plants and exposing their roots to daylight for two to three weeks but this completely unnatural practice is, thankfully, no longer recommended and I, for one, have never done it. Pruning, need not be complicated: simply cut out, using very sharp secateurs, any dead, damaged or diseased stems and dispose of them sensibly. If you feel that the rest of the plant is a bit out of hand then, by all means, prune back any excessive growth to a height you — not the books or foreign television programmes — are comfortable with and that, dear readers, is that!
Healthy prunings can be made into cuttings and propagated: select strong stems only, cut them into lengths between six to eight inches long, remove all but the top four leaves and then, instead of using chemical rooting powder / solution, simply dip the lower end of the stem in pure honey and plant in pots of good quality, well draining compost, water lightly, keep in light shade and you should, in time, have lots of new rose plants to find homes for.
It could also be that you like your existing rose plants exactly as they are and, in which case, forget all about pruning and just leave them be, but do pay attention to their ‘food’ of course.
In general, roses enjoy at least six hours a day of direct sunshine although some varieties — the Floribunda rose called ‘iceberg’ for example — will still bloom with four hours, not less, of sunshine each day.
The subject of roses is too vast to include everything here but, I hope, this information has simplified at least some rose lore for you.
