Planting Siberian Iris

Upon receipt, soak your rhizomes in water overnight. Plant your Siberian Iris deeper than other Iris, covering the rhizomes with one or two inches of soil. Space your plants two feet apart. Siberian Iris prefer acidic soil (pH 5.5 to 6.9). Peat moss, compost, and humus all work as soil enhancers. Plant your Siberian Iris where they will receive full sun. Good drainage is essential, as Siberians thrive in moist but not soggy conditions.
