Setup, Compatibility & Care
Sowing: Sow seeds thinly from April to May or August to October. Use a moist seed compost, lightly covering the seeds. Maintain a warm position of 10–15°C and keep the compost consistently moist.
Growing On: Once seedlings are large enough to handle, transplant them 5 cm apart into trays of potting compost or individually into 8 cm pots. Keep them in a light area, but out of direct sunlight.
Planting Out: Gradually acclimate young plants to outdoor conditions over 2–3 weeks. Plant them out once all danger of frost has passed, ensuring a spacing of 45 cm between plants.
Location & Soil: Delphiniums thrive in a sunny, sheltered spot with fertile, well-drained soil. Avoid exposed, windy locations.
Care: Water and feed well during spring and early summer. Staking is recommended for the tall stems. Deadhead spent flower spikes to encourage a potential second flowering.
Caution: These plants are harmful if eaten. Keep out of reach of children and pets.
