|
Planting Instructions
|
- Site selection: Choose a location with part shade to full shade and rich, moist, well-draining soil.
- Soil preparation: Enrich the soil with organic matter (compost, peat moss) to retain moisture and improve drainage.
- Planting depth: Set the crown of the plant just at or slightly below soil level.
- Spacing: Space plants 18–24 inches apart to allow for air circulation and mature spread.
- Best time to plant: Spring or fall, when soil is moist and temperatures are cooler.
|
Pruning & Maintenance
|
- Deadhead spent blooms to maintain tidiness, though it’s not necessary for continued flowering.
- In late fall or early spring, cut back old foliage to the ground to make way for new growth.
- Astilbe dies back naturally in winter and regrows in spring.
|
Water Needs
|
- Requires consistent moisture, especially during dry periods.
- Soil should be evenly moist but not waterlogged.
- Mulch helps retain soil moisture and keep roots cool.
|
Light Needs
|
- Part shade to full shade is ideal.
- Can tolerate , but avoid hot afternoon sun, especially in warmer zones, as it may scorch the foliage or dry out the plant.
|
Harvesting
|
- Cut flowers are suitable for fresh arrangements.
- Can also be dried for use in floral crafts.
- Harvest stems when blooms are fully open for best appearance.
|
Fertilizing
|
- Apply a balanced, slow-release fertilizer in early spring as new growth begins.
- For richer flowering, consider a phosphorus-boosted formula (e.g., 10-20-10).
- Mulch with compost annually to improve soil fertility and moisture retention.
|
Pollination
|
- Pollinated by insects, particularly bees and butterflies.
- While not grown for seed production, it is capable of producing seed when pollinated by another astilbe of compatible type.
|
Companion Plants
|
Pairs well with other shade- and moisture-loving plants: - Hostas
- Ferns
- Heuchera (Coral Bells)
- Brunnera
- Ligularia
- Tiarella
- Japanese Forest Grass (Hakonechloa)
These plants provide varied foliage textures and colors to complement Astilbe’s upright blooms.
