PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Aster ageratoides ‘Starshine’ in spring when the soil warms up. This gives the roots time to establish before the growing season begins.
Autumn: Early autumn planting also works well, allowing the plant to settle before winter dormancy, ensuring vigorous growth in the following spring.
Site Selection
Sunlight: Aster ageratoides ‘Starshine’ grows well in full sun to partial shade. Choose a location where it will receive at least 6 hours of sunlight per day for optimal flowering.
Soil: This perennial thrives in well-drained soil. Enhance poor soils by incorporating compost or organic matter to improve fertility and drainage. Avoid heavy, waterlogged areas, as these can lead to root issues.
Planting Instructions
Prepare the Site: Dig a hole twice the width and the same depth as the root ball to provide ample room for root expansion.
Enrich the Soil: Mix in compost or organic matter to improve the soil’s nutrient content and drainage.
Planting: Position Aster ageratoides ‘Starshine’ so the crown sits level with the surrounding soil. Backfill the hole, gently firming the soil to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to settle the soil and help the roots establish quickly.
Watering Requirements
During Active Growth: Water regularly during dry periods, ensuring the soil remains moist but not waterlogged. Allow the topsoil to dry slightly between waterings.
Dormant Season: Water sparingly during winter, only if the soil becomes excessively dry, as Aster ageratoides ‘Starshine’ requires minimal moisture when dormant.
Feeding
Spring Feeding: Apply a balanced, slow-release fertiliser in early spring to encourage healthy growth and abundant flowering.
Mid-Summer Feeding: A light application of fertiliser in midsummer can boost flowering and maintain plant vigor throughout the season.
Pruning and Maintenance
Deadheading: Remove spent blooms regularly to encourage continuous flowering and keep Aster ageratoides ‘Starshine’ looking tidy.
End-of-Season Care: After flowering ends in late autumn, cut back the stems to ground level. This helps the plant conserve energy for the next growing season.
Mulching
Spring Mulch: Apply a layer of organic mulch, such as bark or compost, around the base of Aster ageratoides ‘Starshine’ in spring to retain moisture, regulate soil temperature, and suppress weeds.
Winter Mulch: In colder months, add a thicker layer of mulch to protect the plant’s roots from freezing temperatures.
Plant Support
Staking: Aster ageratoides ‘Starshine’ can grow up to 80 cm tall, so provide support in windy areas to prevent stems from bending or breaking. Use discreet stakes or plant supports to maintain the plant’s natural appearance.
