Water
- Moderate Moisture: Coral bells prefer consistently moist but well-drained soil. Ensure that the soil does not become waterlogged, as it can lead to root rot.
- Mulching: Application of mulch around the base of the plant helps retain soil moisture, particularly during hot and dry periods.
Sunlight
- Partial Shade: While they can tolerate full sun, coral bells generally thrive in partial shade, especially in regions with intense heat.
- Morning Sun, Afternoon Shade: Providing a balance of morning sun and afternoon shade is often ideal for ensuring vibrant foliage and prolific blooms.
Fertilizer
- Balanced Fertilizer: Use a balanced, slow-release fertilizer to promote healthy foliage and robust flowering. Application in early spring and midsummer is beneficial.
- Organic Amendments: Incorporating organic matter into the soil during planting and periodically thereafter can enhance the overall soil fertility and structure.
Soil
- Well-Drained: Coral bells thrive in well-drained soil with good aeration, preventing the risk of water stagnation around the root zone.
- Neutral to Slightly Acidic pH: Aim for a soil pH range of 6.0 to 7.0, as coral bells typically prefer slightly acidic to neutral soil conditions.
- Amendment: Adding organic compost or peat moss during planting can improve soil structure and moisture retention capabilities.
Pruning
Proper pruning practices play a crucial role in maintaining the health, shape, and vigor of Heuchera sanguinea ‘Ruby Bells’:
- Deadheading: Removing spent flower spikes not only enhances the plant’s appearance but also encourages the production of new blooms.
- Trimming Foliage: If the foliage becomes tattered or leggy, a gentle trim to remove damaged leaves can revitalize the plant’s overall appearance.
- Division: Every 3-4 years, consider dividing mature clumps to rejuvenate the plant and prevent overcrowding.
Propagation
For those eager to propagate their beloved coral bells, several methods can be employed to achieve successful offspring:
- Division: Dividing mature clumps during the early spring or fall allows for the creation of new plants while rejuvenating the parent plant.
- Leaf Cuttings: Propagate new plants by taking leaf cuttings, ensuring that each cutting has a portion of the stem attached for optimal success.
