Dutch Iris is among the earliest of the spring blooming bulbs, often emerging through the snows of late winter. The striking colors of Dutch Iris are a sure sign spring is on its way. Fall is the best time to plant Dutch Iris and right now, you'll find these bulbs in convenient packages, ready to take home and plant. Dutch Iris will do best when planted in full sun and in well-drained soils. To improve your soil, plan to add 2" or 3" of compost or peat moss to the soil in the existing bed and mix it in thoroughly. Your bulbs will start rooting right away. As the temperatures cool down, Dutch Iris will go dormant. When the soil warms up in the spring, your bulbs will wake up and begin to grow and bloom. Another way to enjoy Dutch Iris is to force them indoors. Forcing bulbs is a way to accelerate the blooms by cooling the bulb off indoors. Like most fall bulbs, Dutch Iris need a "cooling off" period before they will bloom. In this case, the cooling period is about eight weeks. You can use any container to plant your bulbs as long as it has drainage. Dutch Iris bulbs are a great choice to add color to your garden in from early spring on and these hardy bulbs will multiply and spread naturally, giving you spring color for many seasons to come.
