1. Understanding the Growth Cycle of Irises
Irises have a distinct growth cycle that influences when they should be divided. Typically, irises bloom in late spring to early summer, depending on the variety and climate. After blooming, the plants enter a period of dormancy during the hot summer months. This dormancy is crucial as it allows the plant to conserve energy and prepare for the next growing season.
During the dormancy period, the rhizomes (the thickened underground stems of the iris) continue to grow and expand. This growth can lead to overcrowding if not managed properly. Understanding this cycle is essential for timing the division process correctly, ensuring that the plants have enough time to establish themselves before the next blooming season.
