Howdy! Now that I know I'm dealing with rot and not borers, what is the advise for planting irises where the rhizomes grow "vertically"? Pic attached of a few examples.
I actually received quite a few this week that look like this. I'm tempting to plant them as-is. My instinct is telling me the rot would be worse if I try and clean them up. Thoughts?
Side note from the borer string...
As I was cleaning the rot from the irises, I noticed the ones ordered last year were showing no signs of rot. They were planted using only the soilless mix, no soil conditioner was added. (Probably because I ran out.) So I went through all containers and adjusted so the top 3" is soilless mix only. We've had rain almost every day this week and so far so good. I only found one soft spot and cut it out and treated with bleach.
