Troubleshooting
Aquilegia 'Nora Barlow' problems — and how to fix them
Aquilegia 'Nora Barlow' (Aquilegia vulgaris 'Nora Barlow') 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.
Leaf miner
Columbine leaf miners leave white winding trails in the foliage. The harm is cosmetic; cut the leaves back hard after flowering and fresh, clean growth follows.
Powdery mildew
White mildew can coat stressed plants in dry, crowded conditions. Shear spent foliage after bloom, water at soil level, and give plants room for air movement.
Aphids on buds
Aphids sometimes cluster on flower stems and buds, distorting opening blooms. Dislodge them with a jet of water or encourage natural predators before colonies build up.
Self-seeding spread
It seeds prolifically and seedlings vary, sometimes reverting to simpler flowers. Deadhead before pods ripen to control spread and preserve the distinctive double form.
