As needed
  • water dropWater

    Coral Bells should be watered thoroughly when the top inch of soil feels dry to the touch, which typically amounts to once or twice a week depending on weather conditions. The goal is to maintain evenly moist soil without waterlogging the plant, as Coral Bells prefer a consistent level of moisture. During periods of drought or extreme heat, additional watering may be necessary. Apply water directly to the soil to avoid wetting the foliage, which can lead to fungal diseases. An average watering might involve giving the plant approximately 1 gallon of water every 7 to 10 days, adjusting as necessary for climate and soil drainage.

  • sunLight

    Coral Bells thrive in conditions where they can receive partial shade to full shade, particularly avoiding the harsh afternoon sun. The ideal spot for them is one where they can benefit from morning sun and dappled light throughout the day, which encourages vibrant foliage colors. While they can tolerate some level of direct sunlight, too much will scorch their leaves, so a location under the canopy of taller plants or trees is often perfect.

  • thermometerTemperature

    Coral Bells are hardy in a wide temperature range and can survive in temperatures as low as 0°F and as high as 85°F. They prefer to be grown in an environment where the temperature hovers between 60°F and 70°F for optimal growth. They can tolerate brief periods of hotter or colder weather, but prolonged exposure to extremes outside of their survivable range can damage or kill the plant.

  • scissorsPruning

    Pruning Coral Bells involves removing any dead or damaged foliage to maintain plant health and encourage new growth. They should be pruned in early spring before new growth begins, which will also help to shape the plant and enhance its appearance. If desired, spent flower stalks can be cut back after blooming to tidy up the plant. Pruning is not often required, but an annual check to remove old, unsightly leaves can keep Coral Bells looking their best.

  • circleLife cycle

    Heuchera 'Delta Dawn', commonly known as Coral Bells, begins its life cycle as a seed which, when sown, will germinate given the right conditions of warmth and moisture. The seedling stage follows germination, where the plant establishes its root system and produces its first true leaves. Juvenile Coral Bells then enter a vegetative growth phase, where foliage matures, exhibiting the plant's characteristic round, lobed leaves that often boast a blend of colors, including green, yellow, and red hues. Upon reaching maturity, Heuchera 'Delta Dawn' will start producing flowering stalks, typically in late spring to early summer, with small bell-shaped flowers that attract pollinators such as bees and butterflies. After pollination, seeds will develop and once mature, can be dispersed for propagation. Throughout its life, Heuchera 'Delta Dawn' may experience dormancy during colder months, followed by a revival of growth in the spring.

      Spring-Early Summer

    • Heuchera 'Delta Dawn', commonly known as Coral Bells, is typically propagated by division. The best time to propagate Heuchera 'Delta Dawn' by division is in the spring or early fall, when the plant is not in active bloom. To do this, carefully dig up the entire plant, making sure to keep the root ball intact. Using a sharp knife or spade, divide the plant into smaller sections, each with several shoots and a healthy portion of roots. Replant the divisions immediately, spacing them about 12 to 18 inches (roughly 30 to 45 centimeters) apart to allow room for growth. Water the new divisions thoroughly to help establish them. This method helps maintain the vigor of the plant and allows gardeners to increase their stock of Heuchera 'Delta Dawn'.
