I posted this under tropical plants and then thought I might have better luck with opinions of folks closer to me. So thanks everyone!

Things are popping up out of the ground here, and I checked on my elephant ear today. I've had it for a few years, cut off all the leaves after the first frost, and leave the stumps, overwinter it in the ground. I was looking forward to dividing it this year. I've never had any problems with it - so far it's been a super easy plant.But... Today I poked around a bit an pulled off the loose pieces of last years "stumps." It was white inside, and the texture of thick cake frosting. It's never looked like that before in the spring, and it doesn't seem right. Also picked out a few little white things that looked maybe like some kind of egg, but I'm not sure and I only found a few. Maybe leaf borer eggs. I seem to get leaf borers every spring, though I don't know what they look like. I just see the holes in the leaves after they open up in my cannas :(A few feet away from the center of the plant it looks like the plant is sending up a shoot.What could be wrong? Should I try to dig it up? What should I look for if I do? Should I destroy it all except the new little shoot on the side and start over? Or can the rest be saved?
