PLANTING and AFTERCARE GUIDE

Best Planting Time

The best time to plant Delphinium grandiflorum ‘Ocean White’ is in spring or early autumn, allowing the roots to establish while the soil is moist and easy to work.

Site Selection

Sunlight: Delphinium thrives in full sun, where it will produce the best flowering display and strong, compact growth.

Soil: Fertile, moist, well-drained soil is ideal. Improving the soil with compost or well-rotted organic matter will help retain moisture and provide nutrients for healthy growth.

Planting Instructions

1. Dig a hole twice the width of the root ball and the same depth.
2. Mix compost or organic matter into the excavated soil.
3. Position your Delphinium so the top of the root ball is level with the surrounding soil.
4. Backfill gently, firm lightly, and water thoroughly after planting to help the plant establish.

Watering Requirements

Keep the soil evenly moist during the growing season, especially during dry periods. Delphinium grandiflorum ‘Ocean White’ prefers consistent moisture but should not sit in waterlogged soil.

Feeding

Apply a balanced fertiliser in spring to encourage healthy foliage and strong flowering. A light supplementary feed during the growing season will help maintain vigour and flowering performance.

Pruning

Remove faded flowers regularly to encourage more blooms and extend the flowering period. Cutting back spent stems will help your Delphinium maintain a neat shape.

Mulching

Apply organic mulch around the base in spring to retain moisture, suppress weeds, and improve soil quality, helping Delphinium grandiflorum ‘Ocean White’ grow well.

Final Tips

With full sun, fertile soil, and consistent moisture, Delphinium grandiflorum ‘Ocean White’ will produce a long-lasting display of white flowers and attract pollinators to the garden.
