PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Aster alpinus ‘White’ in early spring as the soil begins to warm. This timing encourages strong root development and prepares the plant for vibrant spring blooms.
Autumn: For an alternative, plant in early autumn to allow the roots to establish before dormancy, ensuring a head start for the following growing season.
Site Selection
Sunlight: Aster alpinus ‘White’ flourishes in full sun, making it ideal for sunny garden spots. Ensure your planting area receives at least 6 hours of direct sunlight daily.
Soil: Choose well-draining soil to prevent waterlogging. Adding organic matter, like compost, will enhance fertility and structure, promoting robust growth.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the plant’s root ball. This provides ample space for root expansion.
Soil Preparation: Mix compost or well-rotted organic matter into the soil to improve drainage and nutrient content.
Planting: Place Aster alpinus ‘White’ in the hole with the top of the root ball level with the ground. Backfill gently, firming the soil to remove air pockets.
Watering: After planting, water thoroughly to help the soil settle and promote root establishment. Ensure the area is well-draining.
Watering Requirements
Active Growth: Water Aster alpinus ‘White’ regularly during dry periods, allowing the soil to dry slightly between sessions. Avoid overwatering.
Dormant Season: Reduce watering during dormancy, providing moisture only if the soil becomes extremely dry.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to encourage healthy foliage and abundant flowering.
Mid-Summer: A second, light feeding in mid-summer can sustain blooming and maintain the plant’s vigour.
Pruning
Deadheading: Remove spent flowers regularly to prolong the blooming period and keep Aster alpinus ‘White’ tidy.
Autumn Cutback: Trim back the plant after flowering in autumn to encourage fresh, healthy growth the next spring.
Mulching
Spring Mulch: Apply organic mulch around the base of Aster alpinus ‘White’ in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
Winter Protection: In colder seasons, a layer of mulch can insulate the roots, protecting them from frost and ensuring the plant’s survival through winter.
Supporting the Plant
Aster alpinus ‘White’ has a naturally compact growth habit and rarely needs support. However, in exposed areas, consider adding stakes to protect against strong winds.
