Heuchera 'Amber Waves' problems — and how to fix them
Heuchera 'Amber Waves' (Heuchera 'Amber Waves') 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
Plant with the crown at or slightly above soil level; deep planting combined with moisture promotes rapid crown rot.
Vine weevil
Both adult and larval stages are damaging; use biological nematode controls applied in late summer to target larvae in the root zone.
Scorch from afternoon sun
The ruffled foliage can trap heat; provide afternoon shade in warm regions.
Winter die-back
The semi-evergreen foliage may die back in cold winters; tidy in spring when new growth emerges.
Root competition
Aggressive neighbours can outcompete Heuchera; space plants 30-40 cm apart and mulch to define root zones.
