3. Cultivating the Purple Iris: A Guide to Success
Growing healthy and vibrant purple irises requires careful attention to their specific needs.
Planting:
The best time to plant irises is in late summer or early fall, allowing them to establish roots before winter.
Choose a sunny location with well-drained soil. Irises prefer at least six hours of direct sunlight per day.
Prepare the soil by loosening it and adding compost or other organic matter.
Plant rhizomes (for bearded irises) horizontally, with the top slightly exposed. Space them about 12-24 inches apart.
Plant bulb type iris at the depth indicated on the packaging.
Soil and Drainage:
Irises prefer slightly acidic to neutral soil (pH 6.0-7.0).
Good drainage is crucial, as irises are susceptible to root rot in waterlogged soil.
Amend heavy clay soil with sand or compost to improve drainage.
Watering:
Water irises deeply after planting and during dry periods.
Avoid overwatering, as this can lead to root rot.
Once established, bearded irises prefer less water. Siberian and Japanese irises prefer more moisture.
Fertilizing:
Fertilize irises in early spring and again after blooming.
Use a balanced fertilizer, such as 10-10-10, or a fertilizer specifically formulated for irises.
Avoid high-nitrogen fertilizers, as they can promote foliage growth at the expense of blooms.
Deadheading and Dividing:
Remove spent blooms (deadheading) to encourage more flowers and prevent seed pod formation.
Divide bearded irises every 3-5 years to prevent overcrowding and rejuvenate the plants.
Siberian and Japanese irises can be divided less frequently.
Division is done after the flowering season.
Pest and Disease Control:
Irises can be susceptible to various pests, including iris borers, slugs, and aphids.
Inspect plants regularly for signs of pests and take appropriate measures to control them.
Common diseases include bacterial soft rot and leaf spot.
Ensure good air circulation and avoid overwatering to prevent fungal diseases.
