The more rain you have the more prevalent it becomes. An acid soil is preferred, but Japanese irises are the only beardless irises that require an acid soil. Everyone has their own methods for trying to eliminate moles. The ideal pH for irises is 6.8 (slightly acidic) but irises are quite tolerant of less-than-perfect soils. This retards weeds and allows the roots to remain cooler. Japanese should be planted a little deeper, about two inches, as they make new roots on top of old roots.

If you want to divide and keep all of the irises, you must make the bed bigger. Place fertilizer around rhizomes, not directly on them.
