Troubleshooting
Variegata Brunnera problems — and how to fix them
Variegata Brunnera (Brunnera macrophylla 'Variegata') 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
Cream margins brown in sun, wind, or dry soil; site in cool shade with shelter and keep the soil consistently moist.
Reversion
Plants may throw all-green shoots that outcompete variegated growth; cut reverted sections out at the base promptly.
Powdery mildew
Grey-white coating appears in dry, stagnant air late in the season; improve airflow, water at the base, and remove affected leaves.
Slug and snail damage
Tender spring foliage is grazed by molluscs; use barriers or traps as new leaves emerge.
