PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ is in early spring when the soil begins to warm. This allows the plant to establish roots before the growing season, resulting in robust plants that are ready to bloom in late summer to autumn.
• Autumn: Alternatively, you can plant in autumn. Planting in early autumn allows the plant to settle in before winter, giving it a good head start for the next growing season.

Site Selection

• Sunlight: Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ thrives in full sun or partial shade. For optimal flowering, select a location where the plant will receive at least 6 hours of direct sunlight per day.
• Soil: Choose well-drained soil for your Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’. The plant does not tolerate waterlogged conditions, so ensure the soil has good drainage to prevent root rot. Adding organic matter, such as compost, can improve soil structure and drainage, helping the plant flourish.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice the width of the root ball and the same depth. This provides ample space for the roots to spread and grow comfortably.
2. Soil Preparation: Mix compost or organic matter into the soil to enrich its nutrients and enhance drainage. Aster benefits from fertile soil that promotes healthy growth.
3. Planting: Place your Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ plant into the prepared hole, ensuring the top of the root ball is level with the surrounding soil. Gently backfill the hole, firming the soil to remove any air pockets.
4. Watering After Planting: Water thoroughly after planting to help the roots settle in and establish. Make sure the area drains well to avoid waterlogging, which could damage the roots.

Watering Requirements

• Growing Season: Once established, Asters are moderately drought-tolerant. Water during dry spells, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so ensure that the soil drains well.
• Dormant Season: Reduce watering during the dormant season, only watering if the soil becomes excessively dry. Asters require minimal water in winter.

Feeding

• Spring: Apply a balanced fertiliser in early spring to support healthy new growth. This helps your Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ to develop a strong structure and produce vibrant blooms.
• Mid-Summer: Consider a light feeding in mid-summer to encourage continued flowering. This ensures that your plant remains vigorous and blooms profusely throughout the growing season.

Pruning

• Deadheading: Regular deadheading of your Aster is essential for prolonging its blooming period. By removing spent flowers, you encourage the plant to produce new blossoms and maintain its appearance.
• Autumn Pruning: After the last flowers have faded, cut the plant back to ground level. This prepares the plant for winter dormancy and encourages healthy growth in the spring.

Mulching

• Spring: Apply a layer of mulch around the base of your Aster to help retain moisture, suppress weeds, and regulate soil temperature. Organic materials like bark chips or compost work best for mulching.
• Winter: In winter, mulch around the plant’s base to protect the roots from freezing temperatures and prevent frost heaving. This will ensure your Aster survives and thrives in the following season.

Supporting the Plant

• Staking: While Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ generally has a sturdy stem, it may require staking in particularly windy areas. To avoid plant damage, consider staking taller varieties, especially when heavy blooms appear.

Final Tips

Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ is a low-maintenance perennial that adds colour and interest to the garden. By planting in full sun or partial shade with well-drained soil and following this care guide, your Symphyotrichum (Aster) novi-blegii ‘Winston Churchill’ will reward you with a beautiful display of blooms from late summer into autumn.
