PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The optimal time to plant Delphinium ‘Delgenius Neva’ is in early spring when the soil begins to warm. This allows roots to establish before the growing season, resulting in robust stems and abundant flower spikes.
• Autumn: Early autumn planting also works well, giving Delphinium ‘Delgenius Neva’ time to settle before dormancy and encouraging strong growth in spring.

Site Selection

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

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to give the roots space to spread comfortably.
2. Soil Preparation: Mix compost or organic matter into the soil to boost fertility and drainage.
3. Planting: Place the plant in the hole with the top of the root ball level with 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 during dry periods, but avoid waterlogging. Delphinium ‘Delgenius Neva’ thrives with even moisture.
• Dormant Season: Reduce watering significantly, providing moisture only if the soil becomes very dry.

Feeding

• Spring: Apply a balanced fertiliser in early spring to promote strong growth and vibrant flower spikes.
• Mid-Summer: A light feed can support Delphiniums to maintain healthy stems and encourage continued flowering.

Pruning and Deadheading

• Deadheading: Remove spent flowers to prolong blooming and maintain a tidy appearance.
• Autumn Pruning: After flowering ends, cut stems back to ground level to prepare your Delphinium for dormancy and encourage healthy growth next season.

Mulching

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

Supporting the Plant

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