I don't know anything about rabbit droppings but I am sure they are high in some nutrients for plants. That could have made those particular irises more susceptible to mold.... and being fresh may have made a difference. Interesting, Tom. From the posts so far, leaving fallen leaves on irises overwinter seems to be a good practice. The winters here, with only a few exceptions, are mild and we usually get a single snow every other year so clearing the leaves off gives me a jump on spring. I think I will leave them on the beds this year. I did lose six nice Lantana plants, most of the tuberoses and a few other plants. Several other plants came back but they are tiny..... like a new start. Perhaps the leaves will protect them too. Thanks for posting your gardening practices in regards to the winter ground cover.
