Coral Bells Growing and Maintenance Tips

Grows best in an average to moist, well-drained soil, in partial sun. Newer cultivars are bred to tolerate more extreme growing conditions such as drought, heat, humidity, and exposure levels. Heuchera are very versatile and create an excellent, colour, contrast option, in mass or as an individual, accent perennial. Remove spent flowers from taller cultivars to keep a uniform appearance. When planting, it is important to note that the crown should remain slightly above the soil level to prevent stem rot. Root weevils are a common problem for coral bells.
