|
Planting Instructions
|
- Best Time to Plant: Early spring or fall is ideal, allowing the plant to establish roots before summer heat or winter cold.
Planting Instructions: - Soil Requirements: Prefers well-drained, organically rich soil. While adaptable to various soil types, slightly acidic to neutral soils produce the best results.
- Spacing: Space plants 5-6 feet apart to allow for mature growth and good air circulation.
- Depth: Plant at the same depth as the root ball, ensuring the crown is level with the soil surface.
|
Pruning & Maintenance
|
- Pruning Needs: Prune in late winter or early spring to remove dead or damaged branches. Minimal pruning is needed, as it blooms on old wood.
- Deadheading: Remove spent flowers after blooming to keep the plant tidy and encourage healthy growth.
- Winter Care: Apply mulch around the base in colder climates to protect the roots from freezing temperatures. The exfoliating bark also adds winter interest.
|
Water Needs
|
- Watering Frequency: Water regularly, especially during the first growing season. Keep the soil consistently moist, particularly during hot, dry spells.
- Drought Tolerance: Somewhat drought-tolerant once established, but performs best with consistent moisture.
|
Light Needs
|
- Preferred Light: Partial shade to full shade. It thrives in dappled sunlight, making it ideal for woodland gardens or shady borders.
- Tolerates: Some morning sun, but it prefers to avoid the harsh midday sun, especially in hotter climates.
|
Harvesting
|
💐 For Fresh Cut ArrangementsBest Time to Harvest:
- When flower heads are fully developed but still firm, typically early to mid-summer (June–July).
How to Harvest:
Use clean, sharp pruners.
Cut stems early in the morning, just above a node.
Remove lower leaves and place stems in cool water immediately.
- Vase Life:
- Large panicle blooms last 5–7 days in fresh arrangements if conditioned properly.
🌾 For Drying- Best Time:
- When blooms begin to dry naturally on the shrub and shift to pink or tan shades—usually late summer to early fall.
- Drying Method:
- Strip foliage.
- Hang stems upside down in a dark, dry place, or let them air dry upright in a vase.
- Takes 1–2 weeks to dry fully, preserving their cone shape and muted color.
|
Fertilizing
|
- When to Fertilize: Fertilize in early spring with a balanced, slow-release fertilizer to support healthy growth and abundant blooms. An additional feeding after the first bloom can prolong flowering.
- Type of Fertilizer: Use a general-purpose fertilizer or one formulated for flowering shrubs.
|
Additional Care Tips
|
- Mulching: Apply 2-3 inches of mulch around the base to help retain moisture, regulate soil temperature, and suppress weeds.
- Pests: Generally pest-free, though aphids or spider mites may occasionally be present. Treat as needed with insecticidal soap or neem oil.
- Disease: Ensure good air circulation to prevent fungal diseases such as powdery mildew. Avoid overhead watering.
