PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The ideal time to plant Symphyotrichum (Aster) ageratoides ‘Stardust’ is in spring, allowing roots to establish well before the blooming season.
• Autumn: Planting in early autumn gives the plant time to settle before winter, ensuring robust growth when spring arrives.

Site Selection

• Sunlight: Symphyotrichum (Aster) ageratoides ‘Stardust’ performs best in full sun or partial shade. Ensure the plant receives at least 4-6 hours of sunlight daily to maximize flower production.
• Soil: This perennial prefers well-drained soil. While it adapts to different soil types, incorporating compost or organic matter will improve drainage and nutrient availability.

Planting Instructions

1. Prepare the Planting Area: Dig a hole twice the width and the same depth as the root ball. This allows ample space for root growth.
2. Enhance the Soil: Mix organic matter or compost into the soil to improve its structure and fertility.
3. Planting: Position the root ball so that the top is level with the soil surface. Backfill the hole, pressing the soil gently to remove air pockets.
4. Watering After Planting: Water thoroughly after planting Symphyotrichum (Aster) ageratoides ‘Stardust’ to help the soil settle and support root establishment.

Watering Requirements

• Active Growth Period: Water regularly during dry periods but allow the soil to dry slightly between watering sessions. Overwatering should be avoided to prevent root rot.
• Dormant Season: Reduce watering in winter, only providing moisture if the soil becomes excessively dry.

Feeding

• Spring Feeding: Apply a balanced, slow-release fertiliser in early spring to support healthy growth and vibrant blooms.
• Mid-Season Boost: A light feeding during midsummer can sustain blooming and strengthen the plant’s overall health.

Pruning and Maintenance

• Deadheading: Regularly remove spent flowers from Symphyotrichum (Aster) ageratoides ‘Stardust’ to encourage prolonged flowering and maintain a tidy appearance.
• End-of-Season Care: Cut back the plant to ground level in late autumn or early winter after flowering has finished. This promotes healthy regrowth in the spring.

Mulching

• Spring Mulch: Apply a layer of organic mulch, such as bark or compost, around the base of the plant in spring. This helps to retain soil moisture, regulate temperature, and suppress weeds.
• Winter Mulch: Add extra mulch in winter to protect the plant’s roots from freezing temperatures and prevent frost heaving.

Plant Support

• Staking: Symphyotrichum (Aster) ageratoides ‘Stardust’ generally has strong stems but may benefit from staking in particularly windy areas to prevent bending or breakage.
