WHEN TO PLANT
Posted by Bonnie Hadaway on
Plant iris so that they are well established before the first freezes of winter. You can dig and divide plants after they finished blooming in the spring. Another good time to divide and move your iris rhizomes is in the fall (September in Oklahoma) after they start coming out of their summer dormancy. If you buy plants in the summer and can’t plant them in your garden right away, you can place them in pots. Set them in the shade or semi-shade until you are ready to plant them in the garden this fall. Potted iris that are set in the shade will continue to grow, but will not be stressed by our 100*F plus temperatures. If you do decide to place them in the grown, shield them from the hot sun by placing a shingle or other shade protection next to the plant.
