if lifting Dahlia before the frost, let them dry/ wilt before?

Hello there,
as I want to avoid a mad rush of harvest/work after the first frost I pondered lifting some potted Dahlias of mine earlier.
I know that a light frost is supposed to help the tubers to ripen or go dormant. So if I lift some tubers soon, should I stopp watering them for a week or two? So far the days get still very warm, with cool nights. Some have mildew already and dont look great anymore (neglected them slightly).

Thanks for your advice, cheers

I often bring mine in before the frost. It really doesn't matter whether you water or not, because you will be cleaning them off, dusting them with a fungicide / bulb dust, letting them dry on the surface, and then storing them in a way that you like.

I have some with powdery mildew this fall also. That will all be cut off and discarded.

Hope that helps.
