Choosing the Right Delphinium Varieties
The first step in your delphinium journey is selecting the perfect varieties for your garden. With a wide range of colors, heights, and bloom times available, you’re sure to find the perfect match for your preferences.
Consider these factors:
- Height: Delphiniums come in various heights, from compact varieties reaching just a few feet to towering giants exceeding six feet. Choose varieties that suit your garden space and design.

Planting Delphiniums: A Step-by-Step Guide
Once you’ve chosen your delphinium varieties, it’s time to plant them. Here’s a step-by-step guide to ensure a successful planting process:
1. Prepare the Soil: Delphiniums thrive in well-drained, fertile soil with a slightly acidic pH (6.0-6.5). Amend heavy clay soil with compost or peat moss to improve drainage.
2. Choose the Right Location: Delphiniums prefer full sun to partial shade, with at least six hours of direct sunlight daily. Select a location sheltered from strong winds to prevent damage to their tall stems.
3. Dig Planting Holes: Dig planting holes twice as wide and as deep as the root ball.
4. Space the Plants: Space delphiniums 18-24 inches apart to allow for adequate air circulation and prevent overcrowding.
5. Plant the Delphiniums: Gently remove the plant from its container, loosen the roots, and place it in the planting hole. Backfill the hole with soil, firming it gently around the roots.
6. Water Thoroughly: Water deeply after planting to settle the soil around the roots.
Providing Essential Care for Your Delphiniums
Once planted, delphiniums require consistent care to thrive. Here’s a guide to providing the essential care they need:
- Watering: Water your delphiniums regularly, especially during dry periods. Aim for deep watering, ensuring the soil is moist but not soggy.
- Fertilizing: Delphiniums are heavy feeders and benefit from regular fertilization. Apply a balanced fertilizer every 4-6 weeks during the growing season.
- Staking: The tall stems of delphiniums can easily be damaged by wind or heavy rain. Stake your plants with sturdy stakes and twine to prevent them from flopping over.
- Deadheading: Deadheading spent flowers encourages continued blooming. Remove the flower stalks after they’ve finished blooming to promote new growth.
- Winter Protection: In colder climates, delphiniums may require winter protection. Mulch around the base of the plants to insulate the roots and prevent frost damage.
Troubleshooting Common Delphinium Problems
While delphiniums are generally hardy plants, they can be susceptible to certain pests and diseases. Here’s what to do if you encounter any issues:
- Powdery Mildew: Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves. To prevent powdery mildew, provide good air circulation and avoid overhead watering.
- Aphids: Aphids are small insects that suck sap from the plants, causing stunted growth and leaf discoloration. Control aphids with insecticidal soap or a strong blast of water.
- Slugs and Snails: Slugs and snails can damage delphiniums by feeding on the leaves and stems. Control these pests with slug bait or by hand-picking them at night.
Propagating Delphiniums: Expanding Your Collection
Once you’ve experienced the joy of growing delphiniums, you may want to expand your collection. Delphiniums can be propagated through several methods:
- Seed Starting: Delphiniums can be grown from seed, but it can be a bit more challenging than other methods. Sow seeds indoors in late winter or early spring.
- Division: Divide established delphinium plants in early spring or fall. Carefully separate the clumps and replant them in new locations.
- Cuttings: Take stem cuttings in late spring or early summer. Root the cuttings in a mixture of peat moss and perlite.
Enjoying the Beauty of Your Delphiniums
