Dutch iris bulbs are easy to plant and the irises will make attractive additions to most flower gardens. They can also be used in other landscaping projects where gardens do not already exist. They can be planted in the ground or in containers successfully, making it possible to plant them in wider range of locations.
The iris will grow anywhere from 18 to 24 inches high in planting zones 5 to 9. Allowing a full day of sun to the planted area will be helpful but they should also grow well in partially shaded areas. The iris comes in a variety of colors and will bloom mid to late season. This iris is surprisingly easy to plant.
Step One: Preparations
Choose bulbs for the colors that are desired for the garden. Purchase the number of bulbs that will be needed as well as some compost if it is not readily available at the garden site. Bonemeal will also be required.
Decide where the bulbs will be planted and gather all of the necessary tools and materials in that area to allow for easier working. Irises like well-drained soil and will not do as well in extremely wet conditions.
Iris plants make great cut plants for cutting. The cut flowers can be added to flower arrangements.
Step Two: Work the Soil
Working the soil is important. Dig about 5 inches into the ground and remove any twigs and rocks from the dirt by hand. Mix the dirt with some compost and fill the hole with this mixture.
Step Three: Planting the Bulbs
During the autumn months, a trench can be dug 4 inches deep into the soil. Alternatively, holes can be dug 4 inches deep and 3 inches across for individual bulbs. Plant the bulbs at least 6 inches apart so that they are not overly crowded.
Plant the bulbs with the pointed ends facing up and cover them gently with the soil. Water the area well. Bonemeal can be used to fertilize the area at this particular point.
Step Four: Finishing Up
Take care of the tools and materials, ensuring they are properly cleaned before putting away. Leftover compost can be saved for future projects or added to the garden in the spring. The remaining bonemeal can also be saved for later use.
Step Five: Proper Care and Winter Prep
Iris plants are easy to care for. They do not have to be watered after the initial watering has taken place unless there are drought conditions in the area. Bonemeal is a good fertilizer to use with this type of flower. Fertilization has to take place once during the blooming period.
In the fall, beginning a year after planting, it will be necessary to take steps to ensure new growth. Let the flowers die back before performing this task. The stem of each flower should be pulled from the bulb. They should separate easily. The Dutch iris will add visual appeal to landscaping efforts.
