PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ is in the spring when the soil has warmed. This timing allows the plant to establish strong roots before the growing season, ensuring robust growth and an impressive flowering display.
• Autumn: Alternatively, you can plant in early autumn. This gives the plant time to settle in before the colder months, encouraging healthier growth in the spring.

Site Selection

• Sunlight: Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ thrives in both full sun and partial shade. Choose a location where the plant can receive at least 6 hours of direct sunlight daily to promote strong growth and abundant blooms.
• Soil: Ensure that the soil is well-drained, as Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ does not tolerate waterlogged conditions. Enrich the soil with organic matter, such as compost, to improve drainage and fertility, which will support healthy growth and vibrant flowers.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice the width and the same depth as the root ball of the plant. This provides ample space for the roots to spread out and establish themselves.
2. Soil Preparation: Mix compost or other organic matter into the soil before planting to improve its structure and nutrient content. Asters thrive in nutrient-rich soil that supports vigorous growth.
3. Planting: Place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil surface. Gently backfill with soil, firming it down lightly to remove air pockets.
4. Watering After Planting: Water thoroughly after planting to help settle the soil and promote root establishment. Ensure that the area drains well to avoid any waterlogging.

Watering Requirements

• Growing Season: Once established, Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ is moderately drought-tolerant. Water during dry spells, allowing the soil to dry out slightly between sessions. Avoid overwatering, as excessive moisture can lead to root issues.
• Dormant Season: During the dormant season, reduce watering significantly. Only water if the soil becomes excessively dry, as the plant requires minimal moisture during this period.

Feeding

• Spring: In early spring, apply a balanced fertiliser to give Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ a strong start to the growing season. This will promote healthy growth and ensure that your plant produces abundant blooms.
• Mid-Summer: A light feeding in mid-summer will help support continued flowering and maintain the vigour of your Aster throughout the growing season.

Pruning

• Deadheading: Regularly deadhead your Aster by removing spent flowers. This will encourage new blooms, prolong the flowering period, and help keep the plant looking tidy.
• Autumn Pruning: After the last flowers have faded in autumn, cut back the plant to ground level. This helps prepare the plant for winter dormancy and encourages healthier growth in the next season.

Mulching

• Spring: Apply a layer of mulch around the base of your Aster to retain moisture, suppress weeds, and regulate soil temperature. Organic materials like bark chips or compost are ideal for mulching.
• Winter: Add a layer of mulch in winter to protect the roots from cold temperatures and prevent frost heaving. This will help ensure your plant survives and thrives into the next growing season.

Supporting the Plant

• Staking: Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ is a taller, clump-forming perennial, and while its sturdy stems usually support the plant well, staking may be needed in particularly windy or exposed locations. Staking will help prevent damage and keep the plant upright.

Final Tips

Symphyotrichum (Aster) novi-belgii ‘Crimson Brocade’ is a hardy, low-maintenance perennial that rewards gardeners with continuous blooms from mid-June to October. By planting it in a sunny or partially shaded spot with well-drained, fertile soil, and by following the simple care tips outlined above, your Aster will thrive year after year. Its beautiful white, semi-double flowers with blue backs will add a touch of elegance to your garden, enhancing your outdoor space from early summer until the end of autumn.
