Heucherella ‘Sweet Tea’ is a resilient and adaptable perennial that delivers vibrant color and lush texture with minimal effort. Follow these care tips to ensure your plant thrives:
1. Choosing the Right Location Heucherella ‘Sweet Tea’ thrives in partial to full shade, making it ideal for shaded areas of your garden.
- Partial Shade: Promotes vibrant foliage colors and optimal growth.
- Full Shade: Suitable for warmer climates, though blooms may be less prolific.
- Avoid Direct Sunlight: Intense sunlight can fade or scorch the leaves.
2. Soil Requirements Well-draining, nutrient-rich soil is essential for healthy growth.
- Soil Type: Amend soil with compost or organic matter to improve fertility and drainage.
- pH Level: Slightly acidic to neutral soil (pH 6.0-7.0) is ideal.
- Avoid Waterlogged Soil: Poor drainage can lead to root rot; consider raised beds or amend heavy clay soil with sand or compost.
3. Planting
- Timing: Plant in spring or early fall when temperatures are moderate.
- Spacing: Space plants 24-30 inches apart to allow for natural spreading and airflow.
- Depth: Plant so the crown is level with the soil surface to prevent rot.
4. Watering Consistent moisture is important, especially during establishment.
- Newly Planted: Water regularly to keep the soil evenly moist but not soggy.
- Established Plants: Reduce watering frequency, allowing the topsoil to dry slightly between waterings.
- Drought Tolerance: Once mature, ‘Sweet Tea’ can withstand short periods of dryness.
5. Light Requirements Filtered or indirect light ensures optimal health and foliage vibrancy.

- Shade: Protects foliage in warmer climates, ensuring its vibrant colors.
6. Temperature and Hardiness
- Hardiness Zones: Suitable for USDA zones 4-9.
- Temperature Tolerance: Endures cold winters and warm summers with proper care.
7. Fertilizing Feed sparingly to encourage healthy growth and vibrant foliage.
- Type: Use a balanced, slow-release fertilizer or compost.
- Frequency: Apply once in early spring and again in midsummer for best results.
- Avoid Over-Fertilizing: Excess nutrients can weaken the plant and reduce foliage vibrancy.
8. Mulching Mulch around the plant base to retain moisture and regulate soil temperature.
- Material: Organic mulch such as shredded bark or compost is recommended.
- Depth: Apply a 2-inch layer, ensuring mulch does not touch the crown to prevent rot.
9. Pruning and Maintenance
- Deadheading: Remove spent flower stems to maintain a tidy appearance and encourage continuous blooming.
- Trimming: Cut back damaged or dead foliage in late winter or early spring before new growth emerges.
- Dividing: Divide and replant every 3-4 years to prevent overcrowding and rejuvenate the plant.
