Q: When to sow delphinium seeds?

Indoors: Delphinium seeds can be sown indoors 8-10 weeks before the last expected frost in your area. This generally means sowing in late winter or early spring. Sowing seeds indoors allows them to germinate in a controlled environment, providing a head start for the growing season. Outdoors: You can also sow delphinium seeds directly outdoors in early spring after the danger of frost has passed or in late summer to early autumn, allowing them to establish before winter. For best results, plant them in a well-draining, sunny spot with rich soil.

Q: When to plant delphiniums?

Spring Planting: If you’re planting young delphinium plants or those started indoors, transplant them into the garden in spring, after the risk of frost has passed. This allows them to establish roots before the warmer summer months. Autumn Planting: In milder climates, delphiniums can also be planted in autumn. Planting around that time helps the plants develop a strong root system before the winter sets in, leading to vigorous growth and blooms the following spring. Location and Soil Requirements: Choose a location that gets full sun or partial shade, and ensure the soil is rich, well-drained, and slightly alkaline for optimal growth.

Q: When does delphinium bloom?

Blooming Season: Delphiniums typically bloom in early to mid-summer, usually from June to July. In some regions or with proper care, they may also produce a second bloom later in the summer or early autumn, especially if the spent flower spikes are cut back. Bloom Duration: The flowering period lasts for several weeks, with tall spikes covered in flowers ranging from blue, purple, pink, and white, creating a stunning display in gardens. Encouraging Re-blooming: To extend the blooming period or encourage a second bloom, it’s important to deadhead the flowers after the first blooming phase and maintain adequate watering and fertilisation.
