Jubilee Celebration Rose problems — and how to fix them

Jubilee Celebration Rose (Rosa 'Jubilee Celebration') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Blackspot

Dark leaf spots and defoliation in wet seasons. Improve airflow, water at the base, remove affected leaves and spray preventatively when disease pressure is high.

Powdery mildew

White film on young shoots when roots are dry. Keep soil evenly moist, mulch well and avoid overcrowding to improve ventilation.

Heavy blooms nodding

Large domed flowers can weigh stems down. Feed for strong growth and site in a sheltered spot; this nodding habit is partly natural to the variety.

Aphids

Colonise bud tips and new growth. Hose off, encourage natural predators, or use insecticidal soap on persistent infestations.
