Troubleshooting
The Generous Gardener Rose problems — and how to fix them
The Generous Gardener Rose (Rosa 'The Generous Gardener') 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
Less prone than older varieties but still possible in wet seasons. Maintain airflow on supports, clear infected leaves and use preventative sprays if pressure is high.
Dry root zone on walls
Wall-trained plants dry out in the rain-shadow. Plant 40-45cm out from the wall, water deeply and mulch to keep roots cool and moist.
Poor flowering low down
Vertical stems bloom mainly at the top. Train main canes horizontally along wires to trigger flowering side-shoots along their length.
Aphids
Soft new climbing growth attracts aphids. Hose off, encourage predators, or treat with insecticidal soap when colonies build up.
