Plant Iris siberica in full sun to partially shaded locations. Plant in the spring after all danger of frost has passed. Soil preparation: The ideal soil is porous and drains well and yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments (peat moss or ground bark). Spread a 3-4" layer of soil amendment, add fertilizer and incorporate together into the soil to a depth of 10". To plant: Dig a hole 4-6" deep in a well drained location. Place the roots 12-24" apart. Cover with soil and water. Mulch in extreme climates. Mass planting: When planting a large quantity of roots in one bed, excavate the entire area to 4-6" deep, work fertilizer into the bottom of the trench, set out the roots and then cover them all at once.
After flowering, cut out the flower stalk, leaving the foliage.
