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 require minimal care beyond occasional cutting back. The plants grow well in dry soil and only require watering when the top 2 to 4 inches of soil feels dry.They flower best in areas that receive full, all-day sunlight.asic Care.
