Help----
My Irises are blooming and for the third year some of the stalks are falling over rather than standing straight up. I have them planted in the sun, next to a wall. I have devided them and they are not near as full as many I see that do not have this problem. They have plenty of blooms and appear to be healthy in every other way. Does anyone know whats happening to my beauties? Any advice on Irises would be appreciated. Thanks.
