Planting Giant Delphinium Cultorum Seeds

• Soil Requirements: Delphiniums thrive in well-drained, rich, and slightly alkaline soil. Amend the soil with organic compost to improve fertility and drainage. They prefer soil that is not too dry, but also not prone to waterlogging.
• Planting Depth: Plant the seeds at a shallow depth of about 1/4 inch (0.6 cm). Lightly press the seeds into the soil to ensure good contact but avoid covering them too deeply as they require light to germinate.
