Troubleshooting
Brunnera macrophylla 'Looking Glass' problems — and how to fix them
Brunnera macrophylla 'Looking Glass' (Brunnera macrophylla 'Looking Glass') 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.
Sun scorch
The near-white leaves brown badly in sun or dry soil — more so than greener cultivars. Site in full or dappled shade and keep moist; remove scorched leaves to flush new growth.
Wilting in dry heat
Pale foliage loses moisture fast and wilts. Maintain steady soil moisture and mulch heavily.
Slug and snail damage
Slugs and snails graze tender new leaves in damp shade. Use barriers or wildlife-safe controls.
Crown rot
Waterlogged soil rots the crown over winter. Plant in free-draining, humus-rich ground.
