Heuchera, commonly known as coral bells, are a shade-loving perennial that throws long-stemmed, bell-shaped blooms in May, June and July. Heuchera come in dozens of varieties and vivid colours, including lime green, rich coral, deep oxblood red and sometimes a combination. They prefer rich, organic humus that is moist but well drained, and their flowers attract hummingbirds. Coral bells are a compact plant, growing to approximately 8 inches high. Prune away old growth once a year in the early spring.
Put on a pair of garden gloves and use clean, sharp secateurs to cut away any damaged stalks or leaves. Prune any growth that appears diseased.
Discard cuts in the trash, bypassing your compost pile to prevent the spread of disease.
Thin the outer edges and body of the plant by cutting away all of the old growth. Be extremely careful not to cut new growth, which would inhibit bloom later in the season.
Cut down to the base of each stalk and pull the cuttings outward. Work your way around the plant evenly so that you maintain a consistent, but natural, shape.
Use isopropyl alcohol and a sterile cotton pad to clean your secateurs' cutting blades before pruning your plants to prevent the spread of disease or bacteria.
