To find out how local experts dig, clean, divide, and replant their iris, come to the program on Sunday, September 21 2025 at 1:00 pm.
Greater St. Louis Iris Society members will show how to identify iris rhizomes in need of division. Crowded iris do not bloom–learn how to give you iris the space they need! You will see what part of the plant to trim and replant, and which parts to discard and why.
This part of iris culture is essential to keeping your iris plants healthy and beautiful. Most iris needed dividing every 3 years.
This meeting is held on the campus of the Missouri Botanical Gardens in the Commerce Bank Education Center at 4651 Shaw Ave., St. Louis, MO 63110.
