Cinda, that does sound like my shed also. I don't pick up everything but I do most. This last year I put a lot of potted Iris in it set up on card tables to try to over winter them. I am terribly afraid that some of them did not make it through the winter. I was hoping they would be protected enough inside the shed from the bitter cold but when I checked on them last month, many of the rhizomes were soft and looked dead. I can only hope that some of them made it through the winter.
