Many of you have irises I know.. Has anyone ever encountered a kind of worm that ate up the corm of your iris. My beloved bearded iris was attacked this year and I didn't realize it until the fronds started to yellow up and fall off. I had managed to rescue some of them and transplanted them elsewhere but by then I noticed a secondary attack and this time by earth worms. I was astounded and didn't know earth worms can behave in this way. Does anyone else have a similar experience? What can we do to prevent a recurrence?
