Troubleshooting
Bob Gordon Elderberry problems — and how to fix them
Bob Gordon Elderberry (Sambucus nigra 'Bob Gordon') 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.
Bird predation
Although the drooping heads deter some birds, ripe clusters still attract them; net the bushes as berries colour if you want a full harvest.
Powdery mildew
Crowded, poorly ventilated canes develop white mildew in humid summers; thin old wood and space plants to improve airflow.
Aphid infestation
Soft new shoots and flower heads draw aphids that distort growth; tolerate light numbers for beneficial insects or wash off heavy colonies.
Uneven ripening
Large clusters ripen over time and unripe green berries are higher in toxins, so harvest only fully dark fruit and always cook before eating.
