Answer: You may have given them too much fertilizer - often plants that are overfertilized will put out lots of leaves and no bloom. Don't fertilize them this fall or next spring, and when you resume next year, make sure you're using a low-nitrogen fertilizer - blood meal actually supplies more nitrogen than other nutrients, so you're better off using a black rock phosphate/greensand mixture. Also, bearded iris bloom best in full sun. Hope this helps!
