Question: Do you need to cut back africian iris?

Answer: African Iris remain green all year around and the clumps expand over the years. They do not require cutting back. The flowering stems of fortnight lily are perennial, so don't cut them back after flowering as you might for most other iris like plants. You can dig and divide the clumps if the bed is over-crowded. Divide the rhizomatous clumps after the plants have flowered. The new divisions may take several weeks to get established, so be patient and pamper them for a while. They will grow new flower stems as soon as they're established in their new homes.
