Transplanting & Establishment
2-4 weeksYoung plants develop a rosette of heart-shaped, lobed leaves; root system establishes in the new location
Water regularly after planting. Keep soil consistently moist but not soggy. Mulch lightly around base, keeping crown clear. Protect from direct hot afternoon sun in first season.
Vegetative Growth
4-8 weeksFoliage expands and deepens in color; the plant develops multiple crowns and fills out its mature form
Continue regular watering. Apply balanced, slow-release fertilizer in spring. Remove any damaged or dead leaves. Monitor for slugs and spider mites.
Flowering
6-10 weeks (late spring through early summer)Tall, slender flower spikes emerge above the foliage, bearing numerous delicate white bell-shaped flowers arranged in loose panicles
Continue regular watering; consistent moisture supports prolonged blooming. Deadhead spent flowers to encourage additional blooms. Stake tall flower spikes if needed in windy locations.
Post-Bloom & Summer
8-12 weeksFlowers fade; foliage remains ornamental and may exhibit deepening color tones; plant may produce additional smaller flower spikes
Remove dead flower spikes. Continue watering during dry periods. Apply a balanced fertilizer in early summer if desired. Ensure good drainage to prevent rot.
Dormancy & Winter
October-March (varies by zone)Growth slows; foliage persists (evergreen) but may darken or take on reddish tones in cold climates; plant enters semi-dormant state
Reduce watering; allow soil to dry slightly between waterings. Do not fertilize. Provide winter mulch in zones 3-5 if temperatures drop below -15°F. Remove excessive snow/ice weight from foliage.

Harvest Tips
Coral Bells are ornamental flowers; harvest cut flowers by cutting flower spikes at the base when several flowers have opened along the spike. Cut in early morning for longest vase life (7-10 days). Remove lower foliage from cut stems. For foliage displays, cut entire leaves as needed throughout the season. Plants can be divided in spring for propagation.
