Heuchera, commonly known as coral bells, is best known for richly colored foliage that presents seemingly endless varieties of variegated and two-toned shade combinations. Shade- and sun-loving varieties sport flower spikes sprinkled with tiny blooms, adding extra interest to this popular perennial. Learn how to divide crowns to keep your heuchera blooming and happy.
Organic material mixed with planting soil will provide the best medium for successful growth of coral bells. Plant in well drained, rich soil with the crown of the shoots at soil level. Most varieties prefer part shade, although some can tolerate part to full sun with extra attention to watering. Allow adequate space between heuchera and other plants to ensure air circulation, a disease-preventative measure.
As the heuchera grows, the crown of shoots will create taller, woody stems. Encourage growth by mounding organic matter up around the crown, or dig and replant the whole crown deeper to ensure crown contact with the soil.
Coral bells will begin to look spindly and form a dead-looking area in the center of the plant over time. Dividing the them will provide new shoots for planting and create a healthier mother plant. Dig up the heuchera and shake excess soil from the roots, then divide each shoot or clump of shoots with roots intact. Replant, allowing for up to two feet of growth for each new plant. Pushing the soil back with a shovel, slip the cutting in and pack with soil, then water.
