PLANTING and AFTERCARE GUIDE

Best Planting Time

The best times to plant Eurybia is spring or early autumn. Both seasons allow the plant to establish strong roots before its summer flowering period. Planting during these times encourages healthier growth and longer-lasting displays of its signature airy blooms

Site Selection

Sunlight

Eurybia divaricatus ‘Beth Chatto’ performs beautifully in partial shade but will also tolerate brighter positions if the soil retains moisture. It is particularly effective in dappled shade under trees or alongside taller perennials.

Soil

For best results, grow Eurybia divaricatus ‘Beth Chatto’ in well-drained but moisture-retentive soil enriched with organic matter. Avoid very dry or nutrient-poor sites, as consistent moisture supports abundant flowering.

Planting Instructions

1. Prepare the Hole: Dig a hole twice as wide as the rootball and equal in depth. This gives Eurybia room to establish freely.
2. Soil Preparation: Incorporate compost or organic matter to improve soil texture and fertility—ideal conditions for Eurybia divaricatus ‘Beth Chatto’ to thrive.
3. Planting: Position the plant so the top of the rootball sits level with the soil surface. Backfill gently and firm lightly to eliminate air pockets.
4. Watering After Planting: Water thoroughly to settle the soil and help Eurybia divaricatus ‘Beth Chatto’ begin establishing strong roots.

Watering Requirements

During the growing season, keep the soil moderately moist, especially during prolonged dry spells. Although tolerant of some dryness, Eurybia flowers best when the soil does not completely dry out.

Reduce watering sharply during winter when the plant is dormant, providing only occasional moisture if conditions become unusually dry.

Feeding

Apply a balanced fertiliser in spring to support new shoots and flowering. A light midsummer feed can further extend the blooming period and maintain vigour in Eurybia divaricatus ‘Beth Chatto’.

Pruning

• Deadheading: Remove spent flowers regularly to encourage additional blooms and maintain a tidy appearance.
• Autumn Pruning: After flowering ends in autumn, cut back stems to ground level. This clears old material and supports healthy growth the following year.

Mulching

A spring mulch of compost or fine bark helps conserve moisture, suppress weeds, and enrich the soil—ideal conditions for Eurybia divaricatus ‘Beth Chatto’.
A winter mulch provides added root protection and ensures stability in colder months.

Supporting the Plant

Staking is rarely required, as Eurybia has wiry but resilient stems. In more exposed areas, light support may help maintain its natural, airy shape.
