getting iris to bloom

Asked April 9, 2020, 2:48 PM EDT

Salem area: our yard iris are not setting blooms. Is there anything organic we can do to produce blooms? Would bone meal, epsom salt, or fish emulsion be of use?

Thank you for contacting Extension about your iris. I'm attaching a link to an article that may help you. It indicates: Poor flowering is normally due to planting in excessive shade, using too much fertilizer, planting the rhizomes too deep, or plants that have become too crowded and need dividing.

Poor flowering can also be caused by very immature or damaged rhizomes. Through the process of elimination, you should be able to narrow down the possible causes.

Hello again, I found one more resource that addresses the flowering issue. It is much the same as the first, but I wanted to pass it on.

Thank you for your help on the iris flowering, Lynne Marie. It is so cool to have such quality advice so easily obtained. It sounds like more sun is needed. Thanks again to OSU Extension and to you. Susan Mankins
