Mouldy dahlias

This is the first year I’ve lifted dahlia tubors . I’ve followed advice and cleaned and dried them and stored them into some plastic containers with air vents. But now some have furry mould. I’ve heard about yellow sulphur powder......any tips using or any other tips why they have mould .?

    Take them out of the plastic box and wrap in newspaper then store in cardboard box.  Dry them of again first of course.

    I agree with lyn , sounds like they got a bit damp hence the mold, I stored mine in old compost with a wooden/cardboard box to absorb excess moister, I have to many dahlias now so they go in the Veg/tomato border in the greenhouse.

    Thankyou Lyn and Perki.... I went straight out of the plastic boxes and cut off the furry ends . Will wrap them in paper as suggested . I’ve also ordered some yellow sulphar so might sprinkle that on them too.

    The plastic boxes would have been the issue Helen. Encourages moisture, which you don't want for them.
    Hopefully they'll be fine now  :)

    Thankyou Fairygirl.....I was thinking the plastic boxes it might keep out mice as I have a couple occasionally in my shed. But prefer to take the chance with a cardboard box now.
