Troubleshooting
Columbine 'Nora Barlow' problems — and how to fix them
Columbine 'Nora Barlow' (Aquilegia vulgaris) 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
Grey-white coating on leaves after flowering, especially in dry conditions. Usually cosmetic; remove affected foliage.
Leaf miner
Pale tunnels or blotches in leaves caused by aquilegia leaf miner. Cut back affected foliage; new growth is usually clean.
Aphids
Clusters on young growth and flower stems in spring. Encourage predators or use organic insecticidal soap.
Short lifespan
Individual plants often last only 3–4 years. Allow self-seeding to maintain the display — seedlings may not come true to type.
Sawfly larvae
Caterpillar-like larvae strip foliage quickly. Remove by hand or apply pyrethrin-based spray early.
