Growing and Maintenance Tips for Allium Giant 'Universe'

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.
