  • Planting Instructions

    Plant Dutch Iris bulbs in the mid to late fall, when soil in your area has started to cool. Most iris bulbs can be planted right up until the soil freezes in cold regions.

    Choose a site with full sun to ¾ day sun with well-draining soil. In warmer zones, some protection from afternoon sun will help your iris to bloom longer. Irises thrive in average garden soil, but good drainage is critical to ensure that the bulbs don’t rot.

    Dig holes 4-5” deep and add a handful or two of compost to the soil you removed. Irises have a wide base and tapered top, so plant your irises so the bulb base is about 4” below the soil line with the pointed end facing up. When planted, water the site well. Dutch iris look best grouped in clusters of about 10 per square foot.

    After spring flowering has finished, you’ll want to remove flower heads to prevent the plants from going to seed. This helps ensure all of the plant’s available energy will go into strengthening the bulbs for the following spring season. Don’t remove the foliage until it turns yellow, as the leaves are helping produce energy for the bulb.
