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.
Step 1. Plant iris bulbs in the fall into rich well drained soil that receives a full sun to a half day of sun exposure year round. Half days of sun are tolerated in warmer climates, but iris bloom most profusely when they receive day long sun.Bury the bulb 5 inches deep leaving the top of the rhizome exposed above the soil.eed your iris with a good quality granular bulb fertilizer in the spring to boost bloom. Follow dosing directions on the package. Water in the fertilizer well after application to drive the nutrients down to the bulb and roots.
