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.
When to Transplant Iris. The best time when to transplant iris is in the summer, after the iris have finished blooming, up until fall. Steps for Dividing Iris Plants. To divide your iris, start by lifting the clump of iris plants out of the ground with a spade or fork.
