Pruning is done during dormancy, when plants are inactive, prior to ‘budding’ and ‘shooting’. The best time to prune varies in different parts of the country and our Plantland staff at each branch will advise on the best time for your specific region.
Tackle your rose garden with enthusiasm and the understanding that you are giving each individual plant a ‘fresh start’.
Traditional pruning of roses
Pruning roses in winter ensures that they flower magnificently in
Roses are pruned to encourage better blooms. Pruning is done during their dormant, leafless season. The time varies with each climatic zone. In warm, subtropical areas, prune from the middle of June. In temperate areas, prune in the middle of July.
In cold areas with late frosts, wait until August. In winter rainfall areas, prune from the end of July into August as the rainy season comes to an end.
Prune floribunda roses before hybrid teas as they take longer to come into bloom. Delay pruning heritage roses that only flower once until after they have bloomed in spring.
How to prune
• Remove all dead, diseased and damaged wood.
• Remove all growth that is thinner than a pencil.
• Thin out all crowded or badly placed branches. Branches that rub against each other or cross close to each other must be removed. Always give preference to younger, more vigorous shoots.
• Remove old wood which looks grey and rough, taking this out right down to ground level.
• Where a strong shoot from the base has branched at the top into a candelabra formation, remove the central shoot, leaving
two or three side-shoots. Never cut these strong basal shoots right back.
• Shorten the remaining canes by a third. Shorten to a prominent outwards facing bud.
After pruning Care
• Immediately after pruning, seal cuts with STERISEAL, a sealant that contains a fungicide. Shake well and apply.
• Spray the plants and the surrounding soil with LIME SULPHUR diluted to winter strength (1 part LIME SULPHUR to 10 parts water). If you have had severe black spot, rust or scale infestation, use a stronger solution of 1 to 8. Repeat the application after 10-14 days. Always use fresh LIME SULPHUR.
• Then fertilize with WONDER VITALISER ROSE & FLOWER 8:1:5 (17) + C (8) SR*. Apply 25g for smaller plants and 50g for big plants, water in well, and repeat every four weeks. Alternatively, you may prefer WONDER ORGANIC FERTILISER ROSE & FLOWER + C (8), enriched composted chicken manure with a high organic content. 25g for smaller plants and 50g for big plants, water in well, and repeat every four weeks. Always apply fertilizer to damp soil and scatter it over the entire root area.
• Mulch with a 5cm layer of compost.
• Water regularly.
