Troubleshooting
Heuchera 'Galaxy' problems — and how to fix them
Heuchera 'Galaxy' (Heuchera 'Galaxy') 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.
Crown rot
The No.1 killer of Heuchera; always plant with the crown at or above soil level and prioritise good drainage.
Silver speckle fade
The overlay fades in heavy shade or on very fertile soils; a leaner soil mix and brighter ambient light restore the effect.
Vine weevil
Grubs hollow out roots invisibly; apply biological nematode controls in late summer annually.
Botrytis on lower leaves
Dense mounding habit traps moisture; remove dead lower leaves regularly and improve airflow.
Frost lifting
Shallow root system vulnerable to heaving in hard frosts; press back in and mulch lightly around the crown each autumn.
