Oh gosh Mary that is mudding the water. LOL. But I understand what you are saying. Not sure what my basement temps are. Have never checked. Somewhere in the 40s probably. No heat down there. And sometimes when there's been a lot of rain I'll get some water on the floor.Makes for a lot of humidity so I keep a dehumidifier running. I have been down in the storage rooms at Swan Island. They are big basements with dirt floors. I didn't notice but they probably have fans down there.There are buildings up top- probably where they cut and sort the dahlias. Last year my tubers were starting to wrinkle up by the time I got them cut up and packed away and they didn't store well. This year they are going into the sawdust (which is damp) while they are still plump. I will be watching them closely for any rot.
