Hi can you please tell me how to grow bearded irises ? I have been growing them for along time but some are more difficult for me , like the white immortality reblooming one ... Only blooms in late summer for me ..What is the best fertilizer? Soil ? And the best way to devide them ? Are they all really different in growing and deviding them too ?? I have a real dark purple someone gave me and it grows a lot each year., a dark beautiful yellow was doing great 1 year I got from "plant sale garden club"& it bloomed that spring /early summer too and it's doing great at daughters right now but mine it like getting smaller . they are all in raised bed together But might be too windy in winter here and I read not to mulch too much because of being wet ,so I don't know what to do about cover for winter either .i just put some leaves on them . Thank you so much ...sorry it's so long Melissa
