Best Planting Time
Spring: The ideal time to plant Delphinium ‘Mystery Sensation’ is in spring when the soil begins to warm. This allows the roots to establish firmly before the blooming season, ensuring strong, vibrant spires.
Autumn: You can also plant Delphinium in early autumn. This gives the plant time to settle in before winter dormancy, promoting healthier growth and abundant flowers the following season.
Site Selection
Sunlight: Delphinium ‘Mystery Sensation’ thrives in full sun. Select a location that receives at least six hours of direct sunlight daily to support tall, well-branched stems and prolific flowering.
Soil: Plant in fertile, moist, well-drained soil. Avoid waterlogged areas, as the plant prefers soil that drains freely. Enrich the soil with compost or organic matter to boost growth and flower production.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and equal depth to the root ball. This allows space to establish a strong root system.
Soil Preparation: Mix compost into the soil for improved fertility and drainage.
Planting: Position the plant so the top of the root ball is level with the surrounding soil. Gently backfill and firm the soil to remove air pockets.
Watering After Planting: Water thoroughly to help roots settle. Ensure proper drainage to prevent waterlogging.
Watering Requirements
Growing Season: Water Delphinium ‘Mystery Sensation’ regularly during dry periods, allowing soil to dry slightly between sessions. Overwatering can cause root problems.
Dormant Season: Reduce watering during dormancy. Only provide moisture if the soil becomes very dry, as the plant needs minimal water at this time.
Feeding
Spring: Apply a balanced fertiliser in early spring to give Delphinium ‘Mystery Sensation’ a strong start. This promotes healthy stems and abundant flowers.
Mid-Summer: Light feeding in mid-summer encourages continuous flowering and maintains the vigour throughout its bloom period.
Pruning
Deadheading: Remove spent blooms to prolong flowering and keep Delphinium ‘Mystery Sensation’ tidy. This encourages new flowers to develop.
Autumn Pruning: Cut back the stems to ground level after the last flowers fade. This prepares your Delphinium for the dormant season and supports strong growth next year.
Mulching
Spring: Apply organic mulch around the base to retain moisture, suppress weeds, and regulate soil temperature.
Winter: Mulching during colder months protects roots from frost and helps Delphinium ‘Mystery Sensation’ survive through winter.
Supporting the Plant
Staking: Delphinium ‘Mystery Sensation’ has strong stems but may benefit from staking in windy areas to prevent damage to its tall spires.
Final Tips
Delphinium ‘Mystery Sensation’ is a hardy, low-maintenance perennial that attracts bees and brightens any garden with its stunning double lilac-pink flowers. By planting in full sun with fertile, well-drained soil and following this care routine, this Delphinium will reward you with spectacular blooms from June to September.
