PLANTING and AFTERCARE GUIDE
Best Planting Time
The best time to plant Delphinium grandiflorum ‘Ocean Cheer Blue’ is in spring or early autumn, allowing the roots to establish while the soil is moist and workable. This helps plants settle quickly and produce strong growth before the main flowering season.
Site Selection
Sunlight: A sunny position is best for healthy growth and abundant flowers. Delphinium performs best when it receives plenty of light throughout the day.
Soil: Fertile, moist, well-drained soil is ideal. Incorporating compost or well-rotted organic matter will improve soil structure, drainage, and moisture retention, creating ideal growing conditions.
Planting Instructions
Dig a hole twice the width and the same depth as the root ball.
Mix compost or organic matter into the soil before planting.
Position your Delphinium so the top of the root ball is level with the surrounding soil.
Backfill gently, firm lightly, and water thoroughly after planting to help the roots settle.
Watering Requirements
Keep the soil evenly moist during the growing season, especially during dry periods. Delphinium prefers consistent moisture but should not sit in waterlogged soil.
Feeding
Apply a balanced fertiliser in spring to encourage healthy foliage and strong flowering. An additional light feed during the growing season can help maintain vigour and flowering performance.
Pruning
Remove faded flowers regularly to encourage more blooms and extend the flowering period. Cutting back spent stems will help Delphinium grandiflorum ‘Ocean Cheer Blue’ maintain a neat and compact shape.
Mulching
Apply organic mulch around the base in spring to retain moisture, suppress weeds, and improve soil quality. This also helps maintain consistent soil conditions.
Final Tips
With full sun, fertile soil, regular watering, and occasional feeding, Delphinium grandiflorum ‘Ocean Cheer Blue’ will reward gardeners with a long-lasting display of bright blue flowers and reliable garden performance year after year.
