PLANTING AND AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Echinops ritro in spring as the soil begins to warm. This allows Echinops to develop a strong root system before the main growing season.
• Early Autumn: You can also plant Echinops ritro in early autumn. This gives the plant time to settle before its dormant period and encourages robust growth the following year.

Site Selection

• Sunlight: Choose a location in full sun, where Echinops ritro can receive at least 6 hours of bright light daily. Sun exposure encourages strong stems and vibrant, globular blooms.
• Soil: Echinops thrives in well-drained soil. Avoid waterlogged areas and, if necessary, amend the soil with grit or organic matter to improve drainage and structure.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and equal in depth. This gives Echinops ritro plenty of room for root expansion.
2. Soil Preparation: Mix compost or organic matter into the soil to enhance drainage and provide nutrients.
3. Planting: Place your Echinops in the hole so the top of the root ball is level with the surrounding soil. Gently backfill, firming the soil to eliminate air pockets.
4. Watering After Planting: Water thoroughly to settle the roots, ensuring the soil drains freely.

Watering Requirements

• Growing Season: Once established, Echinops is drought-tolerant. Water only during extended dry spells, allowing the soil to dry slightly between waterings.
• Dormant Season: Reduce watering significantly. Echinops ritro requires very little moisture during dormancy.

Feeding

• Spring: Apply a balanced fertiliser in early spring to support new growth and healthy flower production.
• Mid-Summer: A light summer feed can help Echinops ritro maintain vigour and sustain flowering.

Pruning

• Deadheading: Remove spent blooms regularly to maintain a tidy appearance and encourage continuous flowering.
• Late Autumn: After flowering finishes, cut back to ground level to prepare it for winter and stimulate strong growth the following year.

Mulching

• Spring: Apply a light mulch of compost or bark around the base of Echinops ritro to maintain soil moisture and suppress weeds.
• Winter: A winter mulch can help protect the roots from temperature fluctuations and maintain stable soil conditions.

Supporting the Plant

• Staking: Echinops ritro generally has sturdy stems that do not require staking. However, in particularly windy areas, light support can help prevent stem damage.

Final Tips

Echinops ritro is a low-maintenance perennial that offers bold structure, pollinator appeal, and long-lasting colour from mid- to late summer. By planting in full sun and well-drained soil, and following this simple care routine, you’ll enjoy striking blue globe flowers that enhance your garden year after year.
