Cascade Spice Japanese Iris – Planting & Care Guide

How to Plant

• Location: Choose a site with full sun and consistently moist, acidic soil (pH 5.0–6.5).
• Soil Preparation: Work in compost or peat moss to improve moisture retention. Japanese irises do not tolerate alkaline or dry soil.
• Planting Depth: Set rhizomes just below the soil surface (1 inch deep), with the top slightly exposed in heavy soil.
• Spacing: Space plants 12–24 inches apart for good air circulation.
• Watering: Keep soil consistently moist, especially in the first growing season. Ideal for planting near ponds or in rain gardens.

Care & Maintenance

• Watering: Needs consistently moist soil; never allow to dry out. Mulch helps retain moisture.
• Fertilization: Apply a balanced, slow-release fertilizer in early spring and after blooming.
• Deadheading: Remove spent flowers to encourage new growth.
• Dividing: Divide clumps every 3–4 years in late summer to maintain vigor.
• Winter Care: Cut back foliage after the first frost. In colder zones, apply mulch for winter protection.

Container Planting

• Use a large container (at least 12 inches deep) with drainage holes.
• Use rich, acidic potting soil with added peat moss.
• Water frequently to keep soil consistently moist.
• Overwinter by moving containers to a protected area or burying them in the ground.
