Troubleshooting
Gertrude Jekyll Rose problems — and how to fix them
Gertrude Jekyll Rose (Rosa 'Gertrude Jekyll') 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
The most common rose disease in humid climates; black-fringed leaf spots cause yellowing and leaf drop. Remove and bin infected leaves, water at the base, and improve air circulation.
Lax, floppy stems
This cultivar is known for long, weak canes that flop under the weight of the heavy blooms. Provide a support, peg down canes, or grow it as a short climber for better display.
Aphids
Soft new growth and flower buds attract aphid clusters in spring. Blast off with water, squash by hand, or encourage ladybirds; avoid broad-spectrum sprays that harm pollinators.
Powdery mildew
White powdery coating on leaves and buds in dry conditions with poor airflow. Keep plants well-watered at the root, prune for airflow, and remove affected growth.
