Caring for Roses: Pruning, Feeding & Disease Prevention
Roses are among the most rewarding garden plants, but they do require consistent attention. With the right care, they will reward you with months of beautiful blooms and fragrance.
Pruning
Prune hybrid tea and floribunda roses in late winter or early spring — typically February to March in the UK — just as the buds begin to swell. Cut to an outward-facing bud at a 45-degree angle, slanting away from the bud. Remove dead, diseased and crossing stems first, then reduce the remaining healthy stems by about a third to a half. Climbing roses are pruned differently: remove one or two of the oldest stems at the base each year and tie in new growth horizontally to encourage flowering along the full length of the cane.
Feeding
Roses are hungry plants. Apply a balanced rose fertiliser in early spring as growth begins, and again after the first flush of flowers in June. A high-potassium feed in late summer will harden the growth and improve disease resistance. Avoid feeding after August — late, soft growth is vulnerable to frost damage.
Watering
Water deeply at the base of the plant rather than overhead — wet foliage encourages fungal disease. In dry spells, water once or twice a week, giving the soil a thorough soaking rather than a light sprinkle. Mulching around the base with well-rotted compost or bark will help retain moisture and suppress weeds.
Disease Prevention
The three most common rose diseases are blackspot, powdery mildew and rose rust. All are fungal and spread most readily in warm, humid conditions with poor air circulation. Choose disease-resistant varieties where possible. Remove and dispose of affected leaves promptly — do not compost them. A preventative spray with a copper-based fungicide in spring can help, but good cultural practice is the most effective long-term defence.
