I'm sure I read that leaves should be left alone for six weeks to strengthen the iris and create more offsets. They can be cut back, lifted and moved after six weeks. So if you can pot up the annuals and wait the six weeks, then move enough irises to plant your annuals at that time. Thanks Good ideas. Think I will wait 8 weeks, then lift some Iris and move thus freeing up space for annuals.
Iris plants are dependable perennials that will bloom year after year to add beauty and color to any sunny flower garden. With minimal care, irises will return each spring with long thin leaves and tall stems sporting colorful blossoms. After the irises finish blooming for the summer, cut the blooms from the plants.
