Help my iris are dying
I have over 100 colors and we have had a wet spring. I noticed some were looking pretty sick so I began digging them. I am not sure what I am dealing with. I am finding rot, empty rhizomes and some very small grubs 1/2" that look like maggots some white and some orange. Not many grubs just hit and miss, mainly rot. No sign above of borer damage. What am I dealing with and how do I treat it. I am just sick!
