Growing Tips for Spuria Irises

Site and Soil Preparation

Choose a full-sun location and amend soil generously with compost or organic matter. If soil is acidic, add lime to neutralize.

Planting Rhizomes

• Plant immediately—rhizomes cannot tolerate drying out.
• Depth: 1 inch in heavy soil, 2 inches in sandy soil.
• Spacing: At least 2 feet apart.
• Water consistently from planting through bloom period.

Fertilizing for More Blooms

Feed spuria irises consistently for maximum flowering. One effective strategy: apply a balanced, controlled-release fertilizer in early spring and again in early autumn.
