PLANTIING and AFTERCARE GUIDEE

Best Planting Time

• Spring: Plant Symphyotrichum (Aster) divaricatus ‘Eastern Star’ in spring when the soil begins to warm. This gives the roots time to establish for the upcoming growing season.
• Autumn: Planting in early autumn ensures the plant settles in before dormancy, setting the stage for vibrant growth the following year.

Site Selection

• Sunlight: Asters flourish in partial to full shade, making it perfect for less sunny spots in the garden.
• Soil: This plant prefers well-drained soil. For best results, amend heavy or compacted soil with organic matter such as compost or leaf mould to improve drainage and fertility.

Planting Instructions

1. Prepare the Site: Clear the planting area of weeds and loosen the soil.
2. Dig the Hole: Dig a hole twice the width and the same depth as the root ball.
3. Soil Preparation: Mix compost into the soil to enhance fertility and improve drainage.
4. Planting: Position the plant in the hole with the top of the root ball level with the ground. Gently backfill the hole, firming the soil to eliminate air pockets.
5. Watering: Water thoroughly after planting to help the roots establish.

Watering Requirements

• Growing Season: Water your Aster during dry periods, ensuring the soil stays moist but not waterlogged.
• Dormant Season: Reduce watering during dormancy, providing moisture only when the soil becomes overly dry.

Feeding

• Spring Feeding: Apply a balanced, slow-release fertiliser in early spring to support new growth and abundant flowering.
• Summer Boost: A light feed in mid-summer encourages prolonged blooming and maintains the plant’s vigour.

Pruning

• Deadheading: Remove spent blooms regularly to prolong flowering and keep Symphyotrichum (Aster) divaricatus ‘Eastern Star’ looking tidy.
• Autumn Pruning: After the final blooms fade, cut the plant back to ground level to prepare it for winter dormancy.

Mulching

• Spring Mulch: Add a layer of organic mulch around the base in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
• Winter Protection: Apply mulch in late autumn to protect the roots from harsh temperatures and prevent frost heaving.
