PLANTING AND AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Echinops ‘Platinum Blue’ in spring when the soil begins to warm. This allows the roots to establish before the main growing season and encourages strong flowering.
• Early Autumn: You can also plant in early autumn. This gives the plant time to settle before its dormant period, supporting better growth the following year.

Site Selection

• Sunlight: Echinops ‘Platinum Blue’ thrives in full sun. Choose a location with several hours of direct sunlight daily to promote strong stems and abundant blooms.
• Soil: Ensure well-drained soil. Incorporate compost or organic matter to improve soil structure and prevent waterlogging.

Planting Instructions

• Prepare the Hole: Dig a hole twice the width of the root ball and the same depth to allow Echinops ‘Platinum Blue’ to establish comfortably.
• Soil Preparation: Mix compost or organic matter into the soil to boost drainage and fertility.
• Planting: Position the plant so the top of the root ball is level with the soil surface. Backfill gently, firming to remove air pockets.

Watering Requirements

• Mid-Summer: A light summer feed helps maintain vigour and supports continued blooming.

Pruning

• Deadheading: Remove faded blooms regularly to keep Echinops ‘Platinum Blue’ looking tidy and to encourage ongoing flowering. Seedheads may be left for winter interest if desired.
• Autumn Pruning: After flowering, cut stems back to ground level to prepare the plant for dormancy and promote vigorous growth the following year.

Mulching

• Spring: Apply mulch around the base of Echinops ‘Platinum Blue’ to retain moisture, suppress weeds, and regulate soil temperature.
• Winter: Add mulch in winter to protect the root system and stabilise soil temperatures during the colder months.

Supporting the Plant

• Staking: Echinops ‘Platinum Blue’ usually stands firmly on its own, but light staking may be useful in very exposed or windy positions.
