Aster novi-belgii Mix – Planting & Care Guide

About Aster novi-belgii Mix

Aster novi-belgii Mix, commonly known as Michaelmas Daisy, is a beautiful collection of late-flowering herbaceous perennials that produce masses of colourful daisy-like blooms in shades of pink, purple, violet, blue and white. Flowering from late summer through autumn, these reliable plants provide valuable colour when many other garden flowers are beginning to fade.

Growing to approximately 60–90cm tall with a spread of 45–60cm, Aster novi-belgii forms upright clumps of leafy stems topped with vibrant flowers surrounding bright yellow centres. These nectar-rich blooms are highly attractive to bees, butterflies and other beneficial pollinating insects, making them an excellent choice for wildlife-friendly gardens. Their long-lasting flowers are also ideal for cutting and adding to late-season floral arrangements.

Planting Guide

• Plant in full sun for the best flowering display.
• Will tolerate light partial shade, although flowering may be reduced.
• Prefers fertile, moisture-retentive but well-drained soil.
• Suitable for loam, sandy and clay soils with good drainage.
• Improve poor soils by incorporating compost or well-rotted organic matter before planting.
• Dig a planting hole twice the width of the root ball and the same depth.
• Carefully remove the plant from its container and gently loosen the roots.
• Position the crown level with the surrounding soil surface.
• Backfill with soil, firm gently and water thoroughly.
• Apply a 5–8cm layer of organic mulch around the base to conserve moisture and suppress weeds.
• Space plants approximately 45–60cm apart to allow for good air circulation.

Care & Maintenance

Aster novi-belgii Mix is an easy-to-grow perennial that provides reliable late-season colour.

• Water regularly during the first growing season.
• Keep the soil evenly moist during dry periods.
• Once established, water during prolonged drought.
• Feed in spring with a balanced slow-release fertiliser.
• Apply a high-potash feed during the flowering season to encourage abundant blooms.
• Refresh mulch annually to improve soil quality and conserve moisture.
• Remove weeds regularly from around the base.
• Taller varieties may benefit from support in exposed or windy gardens.
• Divide mature clumps every 3–4 years to maintain healthy growth and flowering.

Pruning

Regular pruning helps encourage healthy plants and prolonged flowering.

• Pinch out the growing tips in late spring to encourage bushier growth and more flowers.
• Deadhead faded flowers regularly to extend the flowering season.
• Remove spent flower stems once flowering has finished.
• Cut the plant back to ground level in late autumn or early spring.
• Divide overcrowded clumps every few years to rejuvenate the plant.
