Description

Symphyotrichum (Aster) novi-belgii ‘White Ladies’ is a beautiful perennial that adds elegance to any garden with its clusters of pure white, double flowers. This upright, clump-forming plant thrives in full sun to partial shade and attracts pollinators such as bees. To ensure your Symphyotrichum (Aster) novi-belgii ‘White Ladies’ thrives and blooms beautifully from summer into autumn, follow this comprehensive planting and care guide.

Best Planting Time

• Spring: The best time to plant Symphyotrichum (Aster) novi-belgii ‘White Ladies’ is in the spring when the soil has warmed. Planting in spring allows the roots to establish before the blooming season begins, ensuring a robust and healthy plant.
• Autumn: Alternatively, you can plant in early autumn. This gives the plant time to settle in before the colder months, promoting stronger growth for the following year.

Site Selection

• Sunlight: Symphyotrichum (Aster) novi-belgii ‘White Ladies’ thrives in full sun or partial shade. Choose a spot where the plant can receive at least 6 hours of sunlight per day. While it can tolerate some shade, full sun will encourage the best flowering performance.
• Soil: Ensure that the soil is well-drained, as Symphyotrichum (Aster) novi-belgii ‘White Ladies’ does not tolerate waterlogged conditions. The plant benefits from fertile, slightly acidic to neutral soil. Enhance soil quality by adding organic matter like compost, which will improve drainage and nutrient availability.

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 will give the roots ample space to spread out and establish firmly.
2. Soil Preparation: Mix compost or organic matter into the soil to improve its texture, fertility, and drainage. This will help ensure the healthy growth of your Aster throughout the season.
3. Planting: Place the plant into the hole, ensuring that the top of the root ball is level with the surrounding soil. Gently backfill with soil and firm it down lightly to eliminate air pockets.
4. Watering After Planting: Water thoroughly after planting to settle the soil around the roots. Ensure that the planting area drains well to avoid standing water, which can cause root rot.

Watering Requirements

• Growing Season: Once established, Symphyotrichum (Aster) novi-belgii ‘White Ladies’ is moderately drought-tolerant. Water the plant during dry periods, allowing the soil to dry slightly between waterings. Avoid overwatering, as excess moisture can lead to root rot.
• Dormant Season: In winter, reduce watering. Asters require minimal moisture during the dormant period. Only water if the soil becomes extremely dry.

Feeding

• Spring: Apply a balanced, slow-release fertiliser in early spring to support strong growth and encourage vibrant blooms. This will help your Symphyotrichum (Aster) novi-belgii ‘White Ladies’ start the growing season on the right foot.
• Mid-Summer: A light feeding in mid-summer can help maintain the plant’s vigour and encourage continuous flowering. Avoid heavy fertilisation, as this can lead to excess foliage growth at the expense of blooms.

Pruning

• Deadheading: Regularly remove spent flowers from your Aster to prolong the blooming period. Deadheading will encourage new flower production, keep the plant tidy, and improve its overall appearance.
• Autumn Pruning: After the last flowers have faded in autumn, cut the plant back to ground level. This will help the plant prepare for winter dormancy and encourage healthier growth the following year.

Mulching

• Spring: Apply a layer of mulch around the base of your Aster to help retain soil moisture, regulate temperature, and suppress weeds. Use organic materials such as bark chips or compost for the best results.
• Winter: In colder months, mulch around the plant to protect the roots from freezing temperatures. A thick layer of mulch will help insulate the plant and prevent frost damage.

Supporting the Plant

• Staking: Although Symphyotrichum (Aster) novi-belgii ‘White Ladies’ has a strong, upright growth habit, staking may be necessary in particularly windy or exposed locations. Use plant supports or stakes to prevent the stems from falling over, especially as the plant reaches its full height of 120 cm.
