Troubleshooting
Fragrant Agrimony problems — and how to fix them
Fragrant Agrimony (Agrimonia procera) 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.
Powdery mildew in dry conditions
White, powdery coating may appear on leaves during hot, dry spells, especially in confined spaces with poor airflow. Improve air circulation, avoid water stress, and apply potassium bicarbonate spray if needed.
Slug damage to young growth
Emerging spring shoots are vulnerable to slug and snail feeding. Apply organic pellets or use copper-tape barriers around pots. Damage is rarely severe once plants reach 20 cm height.
Hooked burr attachment
Seed burrs cling to animal fur and clothing and can spread the plant well beyond its intended planting area. Deadhead promptly after flowering to prevent unwanted self-seeding in adjacent borders.
