Hi I just joined, so if I spary the bleach mixture on my dialhias and let them dry again they should be good or OK to plant next spring? Please help. My mother in law grew these flowers til the day she passed away. My father in law gave me some of hers to grow. I planted them last spring and they grew. I dug them up last fall,when I went to plant them this spring they were covered in white fuzzy's. So I still have them in a cool dry place. Please help. Thanks
