I shoveled out the iris's but saw no sign of any creatures in or around the area. I am just wondering if its not more rot from too much water. I had felt pads down because of the lava rock. I took it all out and am hoping that's all it was. I took the bulbs out and checked thru them, am letting them dry and will work more on them tomorrow. I also found aphids on my butterfly bush, so we cut it all down and sprayed all around what was left and the ground around it...I'm so upset! I have never had that much problem with flower beds and such. I started clearing out all of the junk out of my other flower beds. Not sure if I'm uprooting flowers or not since I can't remember what all is planted there...
