Squirrels here like to dig up the iris right after I plant them. We think they are just curious about what has disturbed the soil, and want to see if another squirrel has maybe buried a nut. they don't eat them, but sometimes, I find a pecan tree growing by an iris label. Maybe they are using my work to dig, kind of like a cowbird relies on some other bird to build a nest and take care of babies for them.
Sneaky squirrels. But i do appreciate how much entertainment and exercise they give my two labradors!
