Plants need deadleafing if they get too
dry over the summer. Evergreen
foliage usually holds well over the
winter; deadleaf or shear off tattered
leaves, if needed, in the spring.
other maintenance Prefers rich,
organic, alkaline, moist soil for best
performance. Moist soil conditions
help to keep plants blooming, though
well-draining soil is essential for
overwintering. Fluctuating winter
temperatures causes frost heaving.
Plant coralbells in spring to allow
them to establish themselves before
winter, and mulch them after the
ground freezes to moderate winter soil
temperatures. Division often is needed
every 3 years in the spring. Plants may
get woody at the base, lifting the
crowns up; top-dress with organic
matter to keep crowns in contact with
the soil. Provide afternoon shade in
hot regions and avoid drought.

deadheading isn’t needed. Deadleaf or
shear off any damaged leaves or old
flower stalks in early spring.

prevent frost heaving. It may also

spring. This species is considerably
