#ProPlantTips for Care:
Be sure you provide your Java Blue Iris with well-drained soil and partial shade (afternoon shade) to full sun. Like other Iris varieties, you'll want to plant them with their roots straddling a mound of soil and covering them two-thirds of the way up the rhizome. Provide a regular supply of moisture their first year and during extended drought, applying 3-4 inches of arborist mulch around their root systems; Bearded Iris are actually drought tolerant once established!
Divide every few years and it's recommended you deadhead after the flowers fade. Trim all the foliage back in the autumn once it yellows and cover the rhizomes loosely with compost, mulch, or evergreen boughs for the winter. Deer, Rabbits, and Squirrels seldom eat these perennials or their rhizomes.
Information About Bare Root Iris
Bare root Iris are shipped as nice fresh-cut divisions with two to three fans of green tops. Keep in mind each Iris variety can have slightly different-sized roots.
Be sure to set your Iris up for success by planting it in the fall in a shallow hole with a hill of soil at its center. Place the rhizome on the mound and bury it two-thirds of the way up, leaving the top of the rhizome exposed. Note, that it's best to cover the rhizome with a thin layer of mulch or leaves to protect it during the coldest months but make sure to uncover it in the spring.
