Why Bearded Iris Won't Bloom: Depth, Sun, and Fertilizer

Bearded iris often fail to bloom due to:

• Recent transplanting: They sulk for years after moving. Leave undisturbed.
• Insufficient sun: Need 6+ hours daily.
• Planted too deep: Rhizomes must be at or just below soil surface.
• Wrong fertilizer: Avoid high nitrogen. Use low-N, high-P (5-10-5) around clumps, water in.

Amend clay soil with compost to unlock nutrients. For vole/rabbit protection, interplant daffodils (toxic to rodents)—especially miniature 'WP Milner' with fine foliage that disappears quickly.
