Seasonal Fertilization Schedule for Healthy Coral Bells

by

Coral Bells, also known as Heuchera, are popular perennial plants loved for their vibrant foliage and delicate flowers. To keep them healthy and thriving, it is essential to follow a proper fertilization schedule throughout the year. This guide provides a seasonal fertilization plan tailored for Coral Bells to ensure lush growth and vibrant color.

Spring Fertilization

Spring is the beginning of the active growing season for Coral Bells. During this time, they need a boost of nutrients to promote healthy growth and new foliage.

  • Apply a balanced, slow-release fertilizer (such as 10-10-10) in early spring.
  • Use about 1 to 2 pounds per 100 square feet, following package instructions.
  • Supplement with a liquid fertilizer every 4-6 weeks if growth appears slow.
  • Avoid over-fertilizing, which can lead to weak, floppy plants.

Summer Care

During summer, Coral Bells are actively growing and flowering. Proper fertilization helps maintain vibrant foliage and supports flower production.

  • Apply a balanced liquid fertilizer every 4-6 weeks during the growing season.
  • Use a fertilizer with micronutrients like iron and magnesium to enhance leaf color.
  • Reduce fertilization if the plant shows signs of stress or if the foliage becomes too lush and floppy.

Fall Fertilization

In fall, Coral Bells prepare for dormancy. Proper fertilization can help the plant store nutrients for the winter months.

  • Apply a low-nitrogen, slow-release fertilizer in early fall.
  • Avoid high nitrogen fertilizers to prevent excessive top growth that could be damaged by frost.
  • Mulch around the base to protect roots during winter.

Winter Considerations

Coral Bells generally go dormant in winter, especially in colder climates. Fertilization is usually not necessary during this period.

If you live in a mild climate, apply a light, balanced fertilizer in late winter to prepare for spring growth.

Additional Tips for Healthy Coral Bells

  • Ensure well-draining soil to prevent root rot.
  • Water consistently, keeping the soil moist but not waterlogged.
  • Remove dead or damaged leaves to encourage healthy new growth.
  • Divide clumps every 3-4 years to maintain vigor.

By following this seasonal fertilization schedule, your Coral Bells will remain healthy, colorful, and vigorous year-round. Proper care and timely feeding are key to enjoying their beauty for many seasons to come.
