Troubleshooting
Heuchera 'Saturn' problems — and how to fix them
Heuchera 'Saturn' (Heuchera 'Saturn') 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
Caused by overwatering or poorly drained soil; lift and replant with improved drainage if crown softens.
Vine weevil
Larvae eat roots leading to sudden wilting; treat with nematodes in late summer or use imidacloprid drench.
Powdery mildew
Appears as white coating on leaves in humid, still conditions; improve air circulation and apply a fungicide if severe.
Leaf scorch
Brown leaf edges from too much direct sun or drought stress; move to shadier position and water more consistently.
Heaving
Frost can push crowns out of ground; mulch well in autumn and firm back in spring.
