Replanting iris plants is the process of dividing and replanting iris rhizomes to propagate new plants or improve the health of existing ones. Irises are popular garden plants known for their showy flowers and ease of care. However, over time, iris clumps can become overcrowded, leading to reduced flowering and increased susceptibility to pests and diseases. Replanting irises every 3-4 years helps prevent these issues and promotes healthy growth.
The best time to replant irises is in late summer or early fall, when the weather is cool and the plants are dormant. To replant irises, dig up the entire clump and divide the rhizomes into individual pieces, each with a fan of leaves and a section of root. Replant the rhizomes shallowly in well-drained soil, spacing them about 12 inches apart. Water the plants deeply after replanting and keep the soil moist until new growth appears.
