Heuchera 'Grape Expectations' problems — and how to fix them
Heuchera 'Grape Expectations' (Heuchera 'Grape Expectations') 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 most common cause of loss; ensure the crown is never buried and soil drains freely after rain.
Silver overlay fade
Metallic patterning fades on over-rich soils or in deep shade; a lean, well-drained soil and dappled light restore the effect.
Vine weevil
A persistent pest of all Heucheras in containers; apply nematode drenches in late summer as a standard preventative.
Frost heaving
Hard frost pushes the crown out of soil; press back in spring and mulch around (not over) the crown each autumn.
Rust
Orange spore pustules on leaf undersides in warm, wet conditions; remove affected leaves and avoid overhead watering.
