PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The optimal time to plant your Delphinium is in spring, allowing the roots to establish before the flowering season begins.
• Autumn: Early autumn planting is also suitable, giving the plant time to settle before dormancy and encouraging vigorous growth the following year.

Site Selection

• Sunlight: Delphinium x cultorum ‘Jupiter F1 Pink’ thrives in full sun, which supports sturdy stems and abundant flower spikes.
• Soil: The plant prefers fertile, moist, but well-drained soil. Adding compost or organic matter will improve soil structure and fertility.

Planting Instructions

1. Prepare the Hole: Dig a hole twice as wide as the root ball and the same depth.
2. Soil Preparation: Mix compost or organic matter into the soil to enhance fertility and drainage.
3. Planting: Place your Delphinium in the hole, keeping the crown level with the surrounding soil. Firm gently to remove air pockets.
4. Watering: Water thoroughly after planting to help the roots establish.

Watering Requirements

• Growing Season: Keep soil evenly moist, especially during dry periods. Delphinium performs best with consistent moisture.
• Dormant Season: Reduce watering significantly once the plant has died back, only providing water if soil becomes very dry.

Feeding

• Spring: Apply a balanced fertiliser to support strong new growth and healthy flower spikes.
• Mid-Summer: Feed again to encourage continued flowering and maintain the vigour of Delphinium x cultorum ‘Jupiter F1 Pink’.

Pruning

• Deadheading: Remove spent flower spikes to encourage secondary blooms and keep the plant tidy.
• Autumn Cutback: After flowering, cut stems back to ground level to prepare your Delphinium for winter dormancy.

Mulching

• Spring: Apply mulch around the base to retain moisture, suppress weeds, and improve soil fertility.
• Winter: A protective mulch layer also helps shield roots from frost and supports strong regrowth the following season.

Supporting the Plant

• Staking: While Delphinium x cultorum ‘Jupiter F1 Pink’ has stable stems, staking may be beneficial for supporting tall flower spikes and preventing wind damage. Place supports early in the season for best results.
