The rose shown above, is a fairly tall shrub. I will like to prune it to a round short bush . How best can I do this? Are you able to advise me on these problems?
Hello @Gardenhelp
It sounds like your rose plant is dealing with multiple issues, including fungal infections like black spot and rust, as well as possible insect damage. While Yates Scale Insect Killer can help manage scale insects, it won't address fungal diseases, which might be causing the discoloration and leaf drop.
To manage and prevent fungal infections, start by removing any affected leaves and stems to reduce the spread of the disease. Dispose of these in the bin rather than composting them to avoid reinfection. Next, apply a fungicide specifically designed for roses, such as Yates Rose Gun Advanced, which targets black spot, powdery mildew, and rust. Ensure you spray the plant thoroughly, covering both the upper and lower surfaces of the leaves.
To prevent future occurrences, practice good garden hygiene by clearing fallen leaves regularly, and consider applying a preventative fungicide during the growing season. Improving air circulation around the plant by spacing it appropriately and avoiding overhead watering can also help reduce fungal growth.
For pruning your rose into a round, short bush, it's best to wait until the late winter or early spring. Use clean, sharp secateurs to cut back the plant. Start by removing any dead or diseased wood, then cut back the remaining stems by about one-third to one-half of their height. Make your cuts just above an outward-facing bud to encourage growth in that direction. Aim to shape the plant evenly, maintaining a balanced, rounded form.
Regular pruning will not only shape your rose but also promote healthy growth and encourage a more robust bloom in the coming season. Consistent care, proper treatment, and pruning will help keep your rose plant healthy and attractive.
