Troubleshooting
Brunnera macrophylla problems — and how to fix them
Brunnera macrophylla (Brunnera macrophylla) 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 scorch
Too much sun or dry soil browns leaf edges. Provide shade and moisture; shear scorched foliage to encourage fresh leaves.
Self-seeding spread
The species self-seeds and can naturalise. Remove spent flower stems if you want to limit seedlings; seedlings come green, not variegated.
Slug and snail grazing
Tender new growth in damp shade is grazed by slugs and snails. Use barriers or wildlife-safe controls.
Crown rot in wet soil
Waterlogged winter soil rots the crown. Plant in humus-rich, free-draining ground.
