I’ve been purchasing bulbs from A.D.R. for many years. The quality is superior and the service fantastic. Chris and his family have always been prompt and accommodating. If you need it, Chris can find it! I wouldn’t shop anywhere else!

Growing and Maintenance Tips for Allium Miniature 'Azureum'

Timing: Plant in fall before the ground freezes to ensure proper root development. Ideal soil temperature for planting is 60°F or colder.
Location: Choose a sunny, well-drained spot—poor drainage can cause bulb rot.
Depth & Spacing: Bury bulbs two to three times their height and space them six to twelve inches apart for optimal growth.
Soil: Maintain a pH of 6 to 7 and enrich with organic matter for better drainage.
Watering: Keep soil moist but not soggy during initial growth; once established, alliums are drought-tolerant.
Foliage Management: Leaves yellow after blooming—plant among perennials to disguise fading foliage.
Deadheading: Remove spent flowers to prevent self-seeding unless you want naturalized clusters.
Fertilization: Apply a balanced fertilizer in early spring to support strong blooms.
Pest & Disease Resistance: Alliums are deer and rabbit resistant but avoid planting in areas with excessive moisture to prevent fungal issues.
Crop Rotation: Change planting locations yearly to prevent soil-borne diseases.
