Best Planting Time
Spring: Plant Delphinium ‘Royal Aspirations’ in spring when the soil begins to warm. This encourages strong root development and helps the plant establish well before flowering.
Early Autumn: Early autumn is also suitable for planting, allowing time for root growth before winter sets in.
Site Selection
Sunlight: Delphinium ‘Royal Aspirations’ flourishes in full sun. Choose a site that receives at least six hours of direct light daily for optimal flowering and sturdy growth.
Soil: This variety prefers fertile, moist, but well-drained soil. Enrich the planting site with organic matter like compost to support healthy roots and prevent waterlogging.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and the same depth as the root ball to give Delphinium ‘Royal Aspirations’ plenty of room to spread.
Soil Preparation: Improve soil structure and fertility by mixing in compost or well-rotted manure.
Positioning: Place the plant with the crown level with the soil surface. Backfill carefully, firming the soil to remove air pockets.
Water Thoroughly: Water well after planting to help settle the roots and eliminate dry pockets in the soil.
Watering Requirements
Active Growth: Keep the soil consistently moist but not soggy during the growing season. Delphinium benefits from deep, regular watering, particularly during dry spells.
Dormancy: Reduce watering in the dormant season, only moistening the soil if it becomes very dry.
Feeding
Spring Feeding: Apply a balanced, slow-release fertiliser in early spring to support vigorous foliage and flower production.
Mid-Summer Boost: Feed Delphinium ‘Royal Aspirations’ again as the flower spikes begin to form to encourage larger, more vivid blooms.
Pruning
Deadheading: Regularly remove spent blooms to promote repeat flowering and maintain a neat appearance.
End of Season Cutback: After flowering ends in midsummer or early autumn, cut your Delphinium back to just above ground level to prepare for dormancy.
Mulching
Spring Mulch: Apply a 5–7 cm layer of organic mulch around the base in spring. This helps conserve moisture, suppress weeds, and keep roots cool.
Winter Protection: A protective mulch in late autumn helps insulate the roots of Delphinium ‘Royal Aspirations’ through colder months.
Supporting the Plant
Staking: Tall stems of Delphinium ‘Royal Aspirations’ may need staking, especially in exposed or windy areas. Use bamboo canes or grow-through supports to prevent damage.
