PLANTING and AFTERCARE GUIDE
Best Planting Time
- Spring: The best time to plant Delphinium is in spring, when the soil is warming. This allows roots to establish before flowering.
- Autumn: Planting in early autumn is also suitable, giving the plant time to settle in before its next growing season.
Site Selection
- Sunlight: Delphinium x cultorum ‘Jupiter F1 Sky Blue’ performs best in full sun, receiving at least 6 hours of direct light daily.
- Soil: Choose fertile, moist but well-drained soil. Add compost or organic matter to improve structure and ensure good drainage.
Planting Instructions
- Prepare the Hole: Dig a hole twice the width of the root ball and the same depth.
- Soil Preparation: Mix organic compost into the backfill soil for fertility.
- Planting: Place your Delphinium in the hole so the crown is level with the soil surface. Backfill and firm gently.
- Watering: Water thoroughly after planting to settle the soil and establish roots.
Watering Requirements
- Growing Season: Keep the soil consistently moist but not waterlogged. Deep watering encourages strong root growth.
- Dormant Season: Reduce watering significantly when the plant is not actively growing.
Feeding
- Spring: Apply a balanced, slow-release fertiliser in early spring to promote healthy stems and flowers.
- After Flowering: Feed lightly after flowering to support continued vigour.
Pruning
- Deadheading: Regularly remove spent flowers from your Delphinium to encourage fresh blooms.
- Cutting Back: After flowering ends in summer, cut stems back to the ground to tidy the plant and prepare for regrowth.
Mulching
- Spring Mulch: Apply an organic mulch around the plant base in spring to retain moisture, suppress weeds, and regulate soil temperature.
- Winter Mulch: Add a protective layer in winter to shield the crown and roots from harsh conditions.
Supporting the Plant
- Staking: The strong stems of Delphinium x cultorum ‘Jupiter F1 Sky Blue’ usually remain upright, but staking may be required in exposed spots to protect blooms.
Final Tips
Delphinium x cultorum ‘Jupiter F1 Sky Blue’ is a compact, low-maintenance perennial that brightens borders with its sky-blue flowers. Plant in full sun, feed and water regularly, and enjoy its elegant blooms in early summer. With the right care, this hardy variety will return year after year, attracting bees and adding structure and colour to your garden.
