Coral Bells Homeowner Growing & Maintenance Tips:
Heucheras and have the stongest colors when grown in partial shade, preferably afternoon shade. They can be grown in full shade but their growth rate will be slower. Some varieties can withstand full sun in northern climates if they have consistant moisture, but their colors tend to fade with the intensity of the sun. The soil should be amended with organic matter prior to planting, have good drainage and a neutral pH. If the heuchera looks tattered by early spring, shear off any damaged leaves to make room for new foliage which will fill in quickly. Heucheras are salt tolerant, which makes them useful in the north along pathways which are salted in winter or for people gardening in coastal regions. Occasionally in northern regions, heucheras have a tendancy to heave out of the ground because of the freeze/thaw cycle. To combat heaving, add an extra layer of compost around the plant's roots in the fall. In the spring, if the plants have heaved at all, the new roots will grow into the fresh new layer of compost.
Interesting Notes:
Heucheras can be grown under Black Walnut trees because they are resistant to the toxin Juglone which the trees emit from their roots.
