Plant Care Tips
To get the most out of your Japanese Iris, make sure that you keep the plant well-watered, particularly in spring, while it is setting its blooms. The Canadian Iris Society suggests "wet in spring, moist in summer" for best results during the present season and the next year. Japanese Irises grow best in rich soil that has a lot of organic material and is slightly acidic. Mulch heavily to conserve moisture and keep the soil cooler. Remove old foliage after the first frost. Apply fertilizer once during spring and again after the blooming period is over. Divide every 3-4 years or when the bloom size or plant height decline. You can transplant Japanese Irises anytime between spring and fall as long as you keep the new plants watered.
