Years prior to now, after I divided my first bunch of irises, I was within the midst of overhauling my complete entrance yard.

To plant, dig a shallow hole and create a mound inside the middle the place the rhizome will sit. Place the rhizome on the mound with the roots in your hole. Cowl the roots after which place a thin layer of soil over the rhizome. You want the rhizome itself to be just below soil diploma, with the best of the rhizome evenly coated in soil. Push any errant roots beneath the soil collectively together with your finger (they’ve an inclination to pop up sometimes!).
Plant rhizomes about 12 to 24 inches apart. Do you have to plant them nearer collectively, you merely may find yourself dividing them sooner, nonetheless in the event you occur to’re okay with that, then plant them as you may!
As a result of the season progresses, the transplanted iris will put down further roots and be settled in its new dwelling for the winter.
