|We planted our irises 2 years ago and some bloomed last spring but none this spring so far. Why is this?

|Irises will stop blooming if they overcrowded and competing for moisture and nutrients or if they are not getting adequate sunshine. You might try digging and replanting them. While you have them out of the ground, amend the soil with compost or other organic matter to loosen it and help it drain well. When you replant, set the rhizomes just barely beneath the soil surface. Hope this helps!
