PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Delphinium is in spring when the soil begins to warm. Planting now allows roots to settle before flowering, resulting in a strong, healthy plant.
Autumn: Alternatively, plant in early autumn so it can establish before dormancy, ensuring vigorous growth in the next season.
Site Selection
Sunlight: Delphinium thrives in full sun but will tolerate partial shade. Select a site with at least 6 hours of direct light daily for best flower production.
Soil: Well-drained, fertile, and moist soil is ideal. Enrich the soil with organic matter or compost to give your Delphinium grandiflorum ‘Hunky Dory White’ the nutrients it needs for strong growth and prolific blooms.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the root ball, allowing Delphinium grandiflorum ‘Hunky Dory White’ to spread its roots comfortably.
Soil Preparation: Work in compost or well-rotted manure to boost fertility and drainage.
Planting: Place the plant in the hole so the top of the root ball is level with the surrounding soil. Backfill gently, pressing down to remove air pockets.
Watering After Planting: Water thoroughly to help roots establish quickly.
Watering Requirements
Growing Season: Keep soil evenly moist during the active growing season. Water regularly, avoiding waterlogging by letting the surface dry slightly between waterings.
Dormant Season: During dormancy, reduce watering significantly and only water if the soil becomes very dry.
Feeding
Spring: Apply a balanced fertiliser in early spring to fuel fresh growth and prepare Delphinium grandiflorum ‘Hunky Dory White’ for flowering.
Mid-Summer: Provide a light feed mid-summer to prolong blooming and maintain vitality.
Pruning
Deadheading: Remove spent blooms promptly to encourage more flowers and keep Delphinium grandiflorum ‘Hunky Dory White’ neat.
Autumn Pruning: After flowering, cut back the stems to ground level. This readies the plant for dormancy and promotes healthier growth next season.
Mulching
Spring: Apply a 5–10 cm mulch layer around the base to retain moisture, suppress weeds, and regulate soil temperature.
Winter: Mulch again to protect the roots of your Delphinium and prevent frost damage.
Supporting the Plant
Staking: Thanks to its compact growth, Delphinium usually requires no staking. In windy or exposed gardens, light support may help protect delicate stems.
Final Tips
Delphinium grandiflorum ‘Hunky Dory White’ is a low-maintenance perennial that delivers dazzling white blooms and supports pollinators. Plant in a sunny spot with fertile, well-drained soil, water consistently, and feed during the season to enjoy abundant flowers. With the right care, your Delphinium will reward you with elegance and charm throughout the summer.
