Planting Dutch Iris
Growing Dutch Iris
Dutch Iris are one the most graceful flowers to bloom early in the spring. The flowers range from light blue, yellow, white and shades of purple. Dutch Iris are grown from small bulbs unlike Bearded Iris which are grown from rhizomes. Dutch Iris are easy to grow, perform well in rock gardens, great for naturalizing and make rather lovely cut flowers for your favorite vase. For the best display of color and fragrance plant in large numbers, you can plant one solid color variety for a large color affect, or mix up varieties for a more natural look. Dutch Iris blooms are simplistic in nature yet have amazing details; many having intricate marks and coloring on the falls which contrast quite nicely with the standards.
Planting Dutch Iris Outdoors
1. Dutch Iris are planted in fall. They will form roots in fall and will bloom in early to mid-spring.
2. Choose a planting location that has well drained soil* and receives full to part sun.
3. Dutch Iris bulbs should be planted at a space of 3-6”
4. Plant the Dutch Iris bulbs “pointed side up” at a depth of 2-3” plant one bulb per hole or create a bouquet affect**.
5. After planting water the planting area thoroughly to ensure the bulbs settle in the soil and have enough moisture to get their roots established. Water as needed during bloom and growth period in spring.
6. Enjoy the lovely blooms in spring
7. Allow the foliage to yellow and dry after the flowers are spent. This will allow the foliage to gather sunlight and make food for the following spring.
8. Once the foliage has yellow and dried you may now remove it by gently pulling the leaves out of the soil. If the leaves do not pull easily they are not ready to be removed.
9. Your Dutch Iris are now dormant and prepared to rest until the following spring!
*How do I tell if my soil is Well Drained?
To tell whether or not your soil is well drained monitor the planting location after it rains. After several hours of a rain shower, all precipitation should soak into the soil. If this does not happen a different location should be chosen, or your soil should be amended with additional organic material such as peat humus, composted manure or compost from your home compost bin…If you are still unsure of your soil content you can send a soil sample to your states extension office for testing. If you soil is high in clay content, do not add sand to it, it will turn your soil into concrete. If your soil is sandy and the water drains a bit too well, you will want to add peat moss or humus to enrich the soil, and increase its water and nutrient holding capacity, which will therefore provide a happy home for your bulbs.
**How do I attain the “bouquet” affect when planting bulbs?
Dig a slightly wider hole than you would for one bulb and place a larger odd number of bulbs in that same hole.
