I have just emptied a pot of dahlias after 2 -3 yrs of blooms. Most of the pot was corms, I now think it was pot bound. Can I separate them and replant or are they no good?

    Many gardeners do not separate the tubers until spring.
    Follow the clean knife and dusting with fungicide practice.

    Even with the new sprouting, you can break those off and new growth will form from the eyes.
    In my research I found that you can plant those long straggly sprouts and tubers can form at the leaf joints.
