Troubleshooting
Olympiad Rose problems — and how to fix them
Olympiad Rose (Rosa 'Olympiad') 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
Can develop fungal leaf spotting in wet seasons despite good overall vigour; clear fallen leaves, mulch, improve airflow, and spray preventively where pressure is high.
Light fragrance
Bred for colour and form rather than scent, so its perfume is mild; pair with fragrant companions if strong fragrance matters in the bed.
Aphids
Greenfly colonise tender shoots and buds; hose off, encourage ladybirds, or use insecticidal soap for larger infestations.
Powdery mildew
White coating on young leaves when roots are dry and air humid; keep soil evenly moist and prune to keep the bush open and airy.
