Troubleshooting
Julia Child Rose problems — and how to fix them
Julia Child Rose (Rosa 'Julia Child') 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.
Aphids
Gather on buds and soft growth; remove with a water jet or insecticidal soap before they distort flowers.
Occasional blackspot
Largely resistant but may spot in very wet seasons; clear fallen leaves and keep foliage dry.
Reduced bloom in shade
Flowering and colour fade in too little light; site in full sun for best performance.
Spider mites in heat
Dry, hot conditions can bring stippled leaves; rinse foliage undersides and monitor during heatwaves.
