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.
The iris flower bulbs should be dug from the bed just before the first frosts and then left to dry for a few days in a frost free location. Once the bulbs are dry, any remaining leaves and excess soil can be removed and they are then ready to be taken to their winter storage quarters.
