**Gardeners Urged to Take Swift Action to Protect Roses Amid Warm Spring Temperatures**
As unseasonably warm weather settles over the UK, gardening experts are urging rose enthusiasts to take key maintenance steps in their gardens this week if they want to ensure a stunning display of blooms this summer. The warning comes amidst growing concerns about an anticipated surge in common pests and diseases affecting these beloved plants.
The higher-than-average spring temperatures may be enjoyable for many, but they have also created near-ideal conditions for blackfly and greenfly—types of aphids notorious for targeting roses. Hayden Salt, a horticultural specialist with over 25 years’ experience and a representative from Jacksons Nurseries, highlighted the heightened risk during this period. He explained that robust preventive measures are needed now, rather than waiting for visible damage to occur.
“Roses are quite prone to pests and diseases, so it’s really important people take steps to protect them,” Salt advised. “But the good news is, with proper care and attention, they can continue to bloom well year after year.” He warned that this spring’s warmer conditions could see aphid numbers—especially blackfly and greenfly—reach levels significantly higher than usual.
Aphids, of which there are roughly 500 different species in the UK, are expert reproducers capable of forming dense colonies in a short space of time. Their presence is most commonly identified on the soft, young growth of roses, and they often leave a tell-tale sticky residue known as honeydew. These pests sap vital nutrients from the plants, potentially causing stunted growth, distorted new leaves, and—in severe cases—the death of the rose itself.
Hayden Salt recommends adopting a thorough approach, saying, “Aphids are usually quite obvious as you can see them on the plant, as well as the sticky substance they secrete. I would recommend using a three-in-one spray every fortnight to tackle this issue, as well as that of fungal diseases.” These sprays not only help to combat insect pests but also provide protection against diseases.
Fungal diseases, particularly black spot, powdery mildew, and rose rust, also tend to thrive during periods of humid, warm weather. These infections can cause unsightly marks on leaves, premature leaf drop, and, in extreme cases, complete plant dieback. “Sprays can be used on a preventative basis so you don’t need to wait for signs of disease or aphid problems to take action,” Salt continued.
Aside from pest and disease control, regular feeding of roses at this time of year is equally important for their overall health and vigour. Hayden Salt suggests applying a slow-release, balanced feed now to ensure the plants receive the nutrients necessary for robust root development and strong flowering. “A rose feed will provide key nutrients that will support healthy root growth and encourage abundant flowering,” he said. “Slow-release versions will allow the feed to be absorbed through the roots over time.”
Looking ahead to the peak flowering months of June and July, Salt advises gardeners to switch to a liquid feed high in potassium—such as a tomato food or liquid seaweed. “Roses expend a lot of energy during the flowering period,” he remarked. “Applying a liquid feed every two weeks whilst they’re flowering helps restore and maintain their energy levels, resulting in continued healthy bud and flower growth throughout the flowering season.”
With roses being a staple feature in many UK gardens, both novice and seasoned gardeners alike are encouraged to act swiftly. By undertaking these few crucial steps—addressing pests, preventing diseases, and providing targeted feeding—gardeners can safeguard the beauty and vitality of their roses through the coming months.
Ultimately, while the British weather is often unpredictable, proactive and informed care can ensure your roses are ready to put on the best display possible, regardless of what the season throws at them.
