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.
Can I trim irises after they've bloomed? Q: My bearded irises have finished blooming. Can I cut the flower stalk back? A: After your irises have bloomed, you can indeed cut down the flower stalk; this process is known as deadheading. You can use a clean knife or pair of utility scissors for this process, if they are too thick to snap off by hand.
