PLANTING and AFTERCARE GUIDE
Best Planting Time
  • Spring: Plant Delphinium elatum ‘Blue Nile’ in spring as the soil begins to warm. This allows the roots to establish firmly before the flowering season, ensuring strong growth and vibrant blooms.
  • Autumn: Alternatively, early autumn planting allows Delphinium elatum ‘Blue Nile’ to settle in before dormancy, promoting robust growth in the following season.
Site Selection
  • Sunlight: Delphinium elatum ‘Blue Nile’ performs best in full sun. Choose a location that receives at least 6 hours of direct sunlight per day to encourage optimal flowering and sturdy stems.
  • Soil: Well-drained, fertile soil is essential for Delphinium elatum ‘Blue Nile’. Incorporate organic matter, such as compost, to improve drainage and soil quality, preventing root rot.
Planting Instructions
  1. Prepare the Hole: Dig a hole twice the width and equal to the depth of the root ball to give Delphinium elatum ‘Blue Nile’ plenty of room for root growth.
  2. Soil Preparation: Mix in compost or organic matter to enhance soil fertility and drainage, supporting vigorous growth and abundant flowering.
  3. Planting: Position the plant in the hole with the top of the root ball level with the soil surface. Gently backfill, firming the soil to remove air pockets.
  4. Watering After Planting: Water thoroughly to help the roots settle and establish. Ensure the area drains well to avoid waterlogging.
Watering Requirements
  • Growing Season: Once established, Delphinium prefers consistently moist soil. Water during dry spells but allow the soil to dry slightly between watering to prevent root issues.
  • Dormant Season: Reduce watering during dormancy. Only water if the soil becomes excessively dry, as minimal moisture is required.
Feeding
  • Spring: Apply a balanced fertiliser in early spring to give Delphinium elatum ‘Blue Nile’ a strong start to the season, supporting healthy stems and vibrant flowers.
  • Mid-Summer: A light feeding mid-season encourages continuous flowering and maintains the plant’s vigour.
Pruning
  • Deadheading: Regularly remove spent blooms to prolong flowering, maintain a tidy appearance, and encourage new flower production.
  • Autumn Pruning: Cut back to ground level after the last flowers fade, preparing the plant for dormancy and promoting healthier growth next season.
Mulching
  • Spring: Apply a layer of mulch around the base to retain moisture, suppress weeds, and regulate soil temperature. Use organic materials like compost or bark chips.
  • Winter: Additional mulch protects roots from cold temperatures and prevents frost heaving, helping your Delphinium survive through winter.
Supporting the Plant

Delphinium elatum ‘Blue Nile’ grows tall with upright stems that may require staking in windy locations. Secure the stems with garden supports to prevent damage and ensure optimal presentation in borders.

Final Tips

Delphinium elatum ‘Blue Nile’ is a striking, bee-attracting perennial perfect for the back of sunny borders. Plant it in fertile, well-drained soil with full sun, follow this care routine, and it will reward you with stunning azure blue blooms from May to July.

    I believe these are the real perennial delphinium, rather than a hybrid between an annual and perennial, so we will see if they will last for more than two years if they do I will be buying more as excellent plants
