PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The optimal time to plant Delphinium ‘Delgenius Juliette’ is in early spring when the soil begins to warm. This allows roots to establish before the growing season, resulting in sturdy stems and abundant flowers.
• Autumn: Planting in early autumn is also effective, giving your Delphinium time to settle before dormancy and promoting strong growth in spring.

Site Selection

• Sunlight: Choose a location with full sun. Delphinium ‘Delgenius Juliette’ requires at least six hours of direct sunlight daily for optimal flowering.
• Soil: Well-drained, fertile soil is essential. Delphinium does not tolerate waterlogged conditions, so amend soil with compost or organic matter to improve structure and drainage.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball, giving the roots of Delphinium ‘Delgenius Juliette’ room to spread comfortably.
2. Soil Preparation: Mix compost or organic matter into the soil to enhance fertility and drainage.
3. Planting: Place the plant in the prepared hole with the top of the root ball level with the surrounding soil. Backfill gently and firm to remove air pockets.
4. Watering After Planting: Water thoroughly to help your Delphinium establish roots, ensuring the area drains well.

Watering Requirements

• Growing Season: Keep the soil consistently moist, especially during dry periods, but avoid waterlogging. Delphinium thrives with even moisture.
• Dormant Season: Reduce watering during dormancy, providing moisture only if the soil becomes very dry.

Feeding

• Spring: Apply a balanced fertiliser in early spring to encourage strong growth and vibrant flowers.
• Mid-Summer: A light feed in mid-summer supports continued flowering and keeps your Delphinium healthy and vigorous.

Pruning and Deadheading

• Deadheading: Remove spent flowers to encourage further blooms and maintain a tidy appearance.
• Autumn Pruning: After flowering ends, cut stems back to ground level to prepare Delphinium ‘Delgenius Juliette’ for dormancy and encourage strong growth next season.

Mulching

• Spring: Apply a layer of mulch around the base to retain soil moisture, suppress weeds, and regulate temperature.
• Winter: Mulching protects the roots of Delphinium ‘Delgenius Juliette’ from frost and temperature fluctuations.

Supporting the Plant

• Staking: Tall flower spikes may need support in windy areas. Use bamboo canes or plant supports to prevent Delphinium ‘Delgenius Juliette’ stems from bending or breaking.
