WaterCoral Bells should be watered thoroughly when the top inch of soil feels dry to the touch. This often equates to watering once a week, but may increase during hot, dry periods or decrease during cooler, wetter spells. Generally, applying about 1 inch of water to replenish the moisture levels is sufficient. Consistency is key to avoid stressing the plant, so try to establish a regular watering schedule. Over-watering can lead to root rot, so ensure that the soil drains well and that the plant is not sitting in water.
LightCoral Bells thrive in part shade to full shade conditions. They should be placed where they will receive morning sunlight and protection from the intense heat of the afternoon sun. An ideal spot would be under the dappled light of a tree canopy or on the north side of a building where they can enjoy bright but indirect light. In too much direct sun, their leaves may scorch, while too little light can lead to poor growth and diminished foliage color.
TemperatureCoral Bells are hardy in a range of temperatures but perform best in conditions between 60 and 70 degrees Fahrenheit. They can generally survive winter temperatures down to 20 degrees Fahrenheit, but should be protected from harsh winter winds. During the summer, they prefer cooler conditions and should be sheltered from extreme heat above 80 degrees Fahrenheit.
PruningPruning Coral Bells is mainly done to remove any dead or damaged leaves and to maintain a tidy appearance. Prune in the spring to remove any winter-damaged foliage and to make way for new growth. During the growing season, trim off any spent flower stalks to encourage additional blooming. Pruning is typically needed once at the beginning of the growing season and occasionally throughout to remove spent flowers.
CleaningAs needed
SoilCoral Bells, commonly known as Heuchera 'Fire Alarm', thrives in well-draining soil rich in organic matter. A suitable mix can be made with equal parts garden loam, peat moss, and perlite or coarse sand to ensure good drainage. The ideal soil pH for Coral Bells is slightly acidic to neutral, ranging from 6.0 to 7.0.
RepottingCoral Bells generally require repotting every 3-4 years as they prefer not to be disturbed too often. It’s best to repot in the spring before new growth begins, carefully dividing the plant if necessary to rejuvenate its vigor.
Humidity & MistingCoral Bells are adaptable to a range of humidity levels but prefer moderate humidity. They can thrive in typical outdoor ambient humidity, so no special humidity adjustments are usually needed when grown in garden settings.

Life cycleHeuchera 'Fire Alarm', commonly known as Coral Bells, begins its life as a seed, germinating in favorable conditions of moisture and light. The plant then develops into a seedling, with the first set of true leaves emerging, distinct from the initial cotyledons. As a young plant, it forms a rosette of colorful leaves close to the ground, and over time, it matures and establishes a robust root system. During its active growth, Coral Bells produce tall flowering stalks bearing small bell-shaped flowers in spring or early summer, attracting pollinators. After pollination, seeds are produced, which can be dispersed to start new plants. Coral Bells are perennial, with their foliage often persisting through winter, and they enter a period of dormancy before resuming growth in the spring.
PropogationPropogation time
Spring-Summer
Heuchera 'Fire Alarm', commonly known as Coral Bells, is best propagated through division, which is the most popular method for this perennial plant. The ideal time for this is either in the spring or early fall when temperatures are cool, which reduces stress on the plant. To propagate by division, carefully dig up the entire clump of Coral Bells, ensuring to preserve as much of the root system as possible. Using your hands or a sharp knife, gently separate the clump into smaller sections, each with a portion of the root system and several shoots. Replant these divisions immediately at the same soil depth as they were previously growing, spacing them about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow room for growth. Water the newly planted divisions thoroughly to help establish them. This method not only helps to propagate new plants but also invigorates older clumps that might have started to die out in the center.
