But how do you delphinium? This guide will walk you through the process of cultivating these majestic flowers, from choosing the right location to ensuring their continued success.
Choosing the Right Location for Delphiniums
Delphiniums thrive in cool, moist environments with ample sunlight. Here’s what to consider when choosing a location:
- Sunlight: Delphiniums need at least 6 hours of direct sunlight daily. They prefer morning sun and afternoon shade, especially in hot climates.
- Soil: Well-drained, fertile soil with a slightly acidic pH (6.0-7.0) is ideal. Avoid planting in heavy clay soil, as it can lead to root rot.
- Wind Protection: These tall plants are susceptible to wind damage. Choose a location sheltered from strong winds, especially in areas prone to gusts.
Planting Delphiniums
Once you’ve chosen the perfect spot, follow these steps for successful planting:
- Timing: Spring is the best time to plant delphiniums, after the last frost. You can also plant in fall in milder climates.
- Spacing: Allow 18-24 inches between plants to give them room to grow.
- Depth: Plant the crown of the plant at or just slightly below soil level.
- Watering: Water thoroughly after planting, ensuring the soil is moist but not waterlogged.
Caring for Your Delphiniums
With the right care, your delphiniums will thrive and reward you with stunning blooms year after year.
- Watering: Delphiniums need consistent moisture, especially during dry periods. Water deeply, allowing the soil to dry slightly between waterings.
- Fertilizing: Feed your delphiniums with a balanced fertilizer every 4-6 weeks during the growing season. Organic compost can also be added to the soil.
- Deadheading: Remove spent flower stalks to encourage new blooms and prevent the plant from going to seed.
- Staking: In areas with strong winds, support tall delphiniums with stakes to prevent them from bending or breaking.
Propagating Delphiniums
You can easily propagate delphiniums through division or from seed.
- Division: Divide established plants in spring or fall, separating them into individual crowns with roots.
- Seeds: Sow delphinium seeds indoors in late winter or early spring. Direct sowing can also be done in the garden after the last frost.
Common Problems and Solutions
While generally hardy, delphiniums can be susceptible to certain pests and diseases.
- Powdery Mildew: This fungal disease appears as a white powdery coating on leaves. Improve air circulation and use a fungicide if necessary.
- Aphids: These tiny insects can suck sap from plants, causing stunted growth. Use insecticidal soap or introduce beneficial insects like ladybugs.
- Slugs and Snails: These pests can damage foliage and flowers. Use slug bait or hand-pick them at night.

The beauty of delphiniums lies in their diverse range of colors. From classic blues and purples to vibrant pinks, reds, and whites, there’s a delphinium variety to suit every taste.
- Blue Delphiniums: Consider ‘Blue Lace,’ ‘Galahad,’ or ‘King Arthur’ for stunning blue blooms.
