Heuchera, also known as Coral Bells or Alumroot, is a versatile and vibrant perennial that adds colour and texture to gardens. Follow this comprehensive planting guide to ensure the successful establishment and continuous beauty of your Heuchera plants.
Site Selection
Sunlight Requirements: Plant Heuchera in locations with filtered sunlight to partial shade. Some varieties tolerate more sun, but protection from intense afternoon sun is generally beneficial.
Soil Quality: Choose well-draining, humus-rich soil. Heuchera prefers slightly acidic to neutral soil pH.
Planting Time
Spring or Autumn: Plant Heuchera in the spring or autumn for optimal root establishment. Avoid planting during extreme weather conditions.
Planting Process
Planting Depth: Dig a hole slightly larger than the root ball of the Heuchera plant. Plant at the same depth as it was in the container. Ensure the crown is just above the soil surface.
Spacing: Space Heuchera plants according to the specific variety, generally around 12 to 18 inches apart.
Watering
Regular Watering: Keep the soil consistently moist, especially during the first growing season. Once established, Heuchera is relatively drought-tolerant, but consistent moisture is beneficial.
Mulching
Mulch Application: Apply a layer of organic mulch around the base of Heuchera plants. Mulch helps retain soil moisture, suppress weeds, and insulate the roots.
Fertilisation
Spring Feeding: Apply a balanced, slow-release fertiliser in the spring as new growth emerges. Avoid excessive fertilisation to prevent overly lush growth.
Pruning
Trimming Spent Flowers: Remove spent flowers regularly to encourage continuous blooming. Trim back any damaged or unsightly foliage throughout the growing season.
Winter Care
Mulch Protection: In colder climates, apply a thicker layer of mulch around Heuchera plants in late autumn to protect the roots from freezing temperatures.
Division
Every Few Years: Heuchera benefits from division every few years to maintain vigour. Divide clumps in the spring or autumn.
Pest and Disease Management
Pest Inspection: Keep an eye out for pests like aphids or spider mites. Treat promptly if detected.
Good Air Circulation: Ensure good air circulation around plants to reduce the risk of fungal diseases.
Container Planting
Well-Draining Containers: If planting in containers, use a well-draining potting mix. Ensure the container has drainage holes to prevent waterlogged soil.
Enjoy the Foliage
Foliage Appreciation: Heuchera is prized for its colourful and unique foliage. Enjoy the array of colours and textures it adds to your garden.
