|My Irises have not bloomed for the past two years. The leaves come up faithfully each spring. Should I cut them back now that it is fall and will that help them bloom next spring?

|Irises will fail to bloom if they are overcrowded or if they are not getting adequate sunshine. I'd cut them back now and dig them up. Divide the rhizomes by snapping off the dead centers and replanting the rhizome ends. Plant the rhizomes just barely beneath the soil surface, then water them in well. They should bloom well for you next year.
