Heuchera, also known as coral bells, is a popular perennial plant admired for its vibrant foliage and delicate flowers. Growing stunning Heuchera in your garden can add color and texture year-round. Here are the top 10 tips to help you succeed.
1. Choose the Right Location
Heuchera thrives in partial shade to full sun, depending on the variety. Most prefer some protection from the intense afternoon sun, which can scorch their leaves. Select a spot with well-draining soil to prevent root rot.
2. Prepare the Soil Properly
Ensure the soil is rich in organic matter and has good drainage. Amend heavy clay soils with compost or sand to improve aeration. A slightly acidic to neutral pH (6.0-7.0) is ideal for Heuchera.
3. Plant at the Right Depth
Plant Heuchera so that the crown is level with the soil surface. Planting too deep can cause rot, while planting too shallow may expose roots. Space plants about 12-18 inches apart for good air circulation.
4. Water Adequately
Keep the soil consistently moist but not waterlogged. Deep watering encourages deep root growth. Mulching helps retain moisture and keeps roots cool during hot weather.
5. Fertilize Appropriately
Feed Heuchera with a balanced, slow-release fertilizer in early spring. Avoid over-fertilizing, which can lead to lush foliage but fewer flowers. Organic options like compost or fish emulsion work well.
6. Prune and Deadhead
Remove dead or damaged leaves throughout the growing season to maintain a tidy appearance. After flowering, deadhead spent flower stalks to encourage new growth and prevent self-seeding.
7. Protect from Pests and Diseases
Watch for pests like aphids, vine weevils, and spider mites. Use insecticidal soap or neem oil if needed. Ensure good air circulation to prevent fungal diseases such as powdery mildew and rust.
8. Mulch for Moisture and Temperature Control
A layer of mulch around the plants helps retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches like bark or leaf mold are ideal.
9. Divide and Propagate
Divide Heuchera every 3-4 years in early spring or fall to rejuvenate plants and promote healthy growth. Propagation can also be done through stem cuttings or by seed for new varieties.
10. Select the Right Varieties
Heuchera comes in a wide range of colors and leaf shapes. Choose varieties that suit your garden’s aesthetic and growing conditions. Popular options include ‘Palace Purple’, ‘Lime Rickey’, and ‘Caramel’.
