Mike, I have a lot of Iris in my yard and I have a problem with them. The stalks grow tall and then fall over. I notice in your picture that your stalks are significantly thicker and stronger looking and I am interested in any fertilizer regimen you use. I believe Nitrogen does so and I think I will give it a shot. Do you use anything special? I also have the same problem with my Peonies, which are planted in about the same area.
Thanks.
You want the nitrogen number lower and the phosphorous and potassium higher, like 5-10-10. Love irises!
