Hi Spokane, I believe a dip in Daconil would do well and then allow them to dry inside. Steve in Baltimore

This is not an uncommon concern. If one leaves them out to dry, they will indeed dry, and in doing so will start to shrivel. Hence the saran wrap method.

If one puts them away too soon, and they are not clean and dry they will indeed tend to form mold / mildew. This is precisely why I strongly recommend that the tubers be given a dusting with a fungicide or bulb dusting. Mine don't go moldy at all with the dusting.

If they get a little mildew on them, give them a spray with Lysol- works great.

Thanks everyone for your input. Does "dollar store" spray work as well?

I also use a strong bleach water for a short time to remove the mildew. Then i cut wherever it looks rotten and do the sulfur thing.

then its vermiculite, or sawdust depending on my mood.

Thanks!

Tc, I would do your cutting first- definitely get rid of anything soft or rotten, then bleach water dip or Lysol spray (I've used that too on fresh cuts and it DOES work great.) That way you've got potential rot hopefully cut out and can add further protection to that fresh cut tissue with the bleach or lysol.

I don't know why you're having such trouble with mildew on your clumps, are they getting enough air circulation while drying? I have just dug, divided, labelled, treated, dried overnight and wrapped mine in as little as 24 hours, or 48, and no problem with mildew.

I hope you have some luck halting the mildew. Am not familiar with dollar store spray. Is it similar to lysol?
