Aster

A brief introduction

Asters, with more than 180 species native to America, Asia, and Europe, have been cherished for centuries. Their fluffy, daisy-like flower heads and vibrant colors beautifully mark the transition into late summer and autumn gardens. Additionally, they attract bees, butterflies, and other insects, supporting pollinators while adding a splash of late-season color. Aster is a testament to nature's generosity.

Popular varieties

Symphyotrichum novae-angliae, known as New England ~ Tall, bushy plant with adorable purple or pink flowers.

Eurybia divaricata, known as Wood Aster ~ Ideal for shaded areas, with delicate white or light purple blooms.

Soil

Asters prefer well-draining, loamy soil enriched with organic matter. They thrive in soil with a neutral to slightly acidic pH 5.5-7.5. Good drainage is essential to prevent root rot and maintain healthy growth.

Light

Asters grow best in full sun, needing at least 6 hours of direct sunlight per day. While they can tolerate partial shade, full sun ensures more prolific blooming and a sturdier plant structure. Ideal temperature: Prefer 15 -21°C during the day, can endure to almost 0°C.

Watering

Asters need regular moisture, particularly in hot and dry spells. Water them thoroughly, but let the soil dry out a bit between waterings. Be careful not to overwater, as asters can develop root problems if they sit in overly wet soil.

Care

Regular deadheading of faded flowers encourages continued blooming. Thin out the plants every couple of years to maintain air circulation and prevent overcrowding, which can lead to powdery mildew. Apply a balanced, slow-release fertilizer in early spring to support their growth.
