Dahlia tuber care for storage

Asked November 12, 2019, 8:50 PM EST

I washed throughly to remove all dirt, separated clumps, Put in 1 gal. Ziplock packed in spagnum moss . It was a brand new bag. Left bag open 3” packed in heavy cardboarc box with lid . Storing them at 45-50 degrees. Did I need to do anything else to them? Someone suggested dipping the tubers in a solution of bleach and water or some kind of anti bacterial powder that you have to wear a mask and gloves. I did not do either of those 2 things. Is there anything else I should have done?
