PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Delphinium ‘Purple Surprise’ in spring when the soil is workable and beginning to warm, helping roots establish before active growth.
• Early Autumn: Early autumn planting also suits Delphinium, allowing time for root development before dormancy.

Site Selection

• Sunlight: Choose a position in full sun for the best flowering performance. Delphinium thrives in bright, open locations.
• Soil: Fertile, moist, well-drained soil is essential. Improve soil with compost or well-rotted organic matter before planting.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and the same depth so roots have room to spread.
2. Soil Preparation: Mix compost or organic matter into the soil to enrich it and improve moisture retention.
3. Planting: Position your Delphinium so the root ball is level with the surrounding soil, then backfill and firm gently.
4. Watering After Planting: Water thoroughly after planting to help Delphinium ‘Purple Surprise’ establish quickly.

Watering Requirements

• Growing Season: Keep the soil evenly moist during active growth to support healthy foliage and flower spikes.
• Dry Periods: Water regularly during dry spells to keep your Delphinium healthy and flowering well.

Feeding

• Spring: Apply a balanced fertiliser in early spring to encourage strong growth and flowering.
• Mid-Season: A light supplementary feed can help maintain vigour and encourage continued flowering.

Pruning

• Deadheading: Remove faded flower spikes to encourage additional blooms and keep Delphinium ‘Purple Surprise’ tidy.
• Seasonal Care: Cut back stems after flowering to encourage fresh growth and possible repeat blooms.

Mulching

• Spring: Apply organic mulch around the base to retain moisture and suppress weeds.
• Seasonal Care: Mulching helps maintain soil fertility and supports the long-term health of Delphinium ‘Purple Surprise’.

Supporting the Plant

• Staking: Tall flower spikes may need support, especially in exposed areas. Supporting Delphinium ‘Purple Surprise’ helps prevent stems from bending or breaking.
