Coral Bells 'Electra' problems — and how to fix them
Coral Bells 'Electra' (Heuchera 'Electra') 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.
Summer colour fade
The vivid spring colouring naturally fades to lime-green in summer heat; this is normal, not a deficiency.
Crown rot
Water sitting against the crown is the primary disease risk; improve drainage and keep mulch away from the crown itself.
Vine weevil
Root larvae cause plants to wilt and collapse; apply nematode biocontrols in late summer.
Leaf scorch
Caused by too much direct sun in warm months; site in partial shade with afternoon protection.
Frost heaving
Crown lift by freeze-thaw cycles; re-firm in spring and mulch around (not over) the crown in autumn.
