All roses benefit from pruning which gives you the opportunity to remove diseased wood and leaves resulting in better blooming and a healthier plant.
In most areas in gauteng this can be done at the end of July, Keep in mind that a light pruning after every flush will also invigorate the bush and promote flowering.
Hybrid teas, floribundas, Fairy Tale, Panarosa, Antico Moderno, spire and miniature roses can all be pruned using the method demonstrated. The same principle applies to standard roses where it’s also important to remove suckers growing from the foot of the main stem.
The exceptions are listed below:
•Colourscape roses can be topped with hedge shears.
•Climbing roses should be untied and unwound from their supports. One should then thin the old wood and cut out at the base before stripping the leaves off. Wind the canes around the structure and retie them.
•Heritage roses don’t like excessive pruning. Just cut out the old, dead wood, shape lightly and retie to the supports, if necessary.
General rules for winter pruning.
-Use clean sharp secateurs to get the cleanest cuts possible.
-Avoid tearing and splitting branches which creates open wounds susceptible to fungus.
-Wash secateurs with soap and water after use and sterilise them in a solution of water and bleach.
-Dry thoroughly to prevent the blades from rusting.
-Protect your arms with long sleeves and garden gloves and wear trousers to cover your legs.
-You can prune even if your rose bush is still flowering. Cut the last flowers for the vase.
-Don’t put diseased leaves on the compost heap; burn them or dispose with municipal refuse.
-If you want to move a rose bush, do this right after pruning.
One very common question asked is, how much should be cut off. The general rule is half to two-thirds. If you want the rose to be slightly taller, leave more. Roses tend to grow longer and develop more stems the older they get. Even if your rose is very tall in its mature state, don’t be afraid to cut it back severely – it will grow back quickly.
Feeding should take place at least a month after pruning for the first time. A good organic granular plant food should do wonders like flower power from protek is what we recommend, and mulch with compost.
One should also look at Aerating the soil around the rose by making small deep holes with a fork to encourage air to flow to the roots.
