Garden Guide Iris Basics

Several basic dos and don'ts apply to most of the rhizomatous Iris. Exceptions are noted in each variety description.

• Plant Iris in full sun.
• Plant Iris in well-drained soil.
• Plant the rhizomes horizontally; leaves go up, roots go down. Fertilize lightly in the early spring.
• Never plant rhizomes more than 1" deep.
• Do not mulch over the rhizomes.
• Do not apply fertilizer directly to the rhizome.
