The Q&A Archives: bearded irises

Question: I have these little "scoop out" spots on my rhizomes of my irises. Is this from grubs or iris borers? If so, what do you recommend to get rid of them? I heard you can use Grub X granules. I wanted to get your opinion first before trying anything. The scoop out thing happened last summer so I am trying to prevent further damage of the rhizomes. Thanks, Nancy
