Heuchera 'Citronelle' problems — and how to fix them
Heuchera 'Citronelle' (Heuchera 'Citronelle') 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
More susceptible to crown rot if planted deeply; always keep the crown at soil level and ensure excellent drainage.
Vine weevil
Check roots of pot-grown plants regularly; apply nematode biological controls in late summer.
Bleaching in sun
Yellow foliage is particularly sensitive; even indirect bright sun can bleach the leaves in summer — provide consistent dappled shade.
Large leaf scorch
Wind scorch can affect the larger leaves; shelter from cold, drying winds in exposed gardens.
Slug damage
Tender new growth and large leaf area are attractive to slugs; protect with organic pellets or copper barriers.
