Cut all the roots off that are not healthy, let it sit out for a week then repot in almost dry soil, do not water until you see new growth. These plants can live on moisture that is stored in their leaves and stems. I don't know where zone 6 is, but it sounds pretty cold. These plants do not tolerate cold and wet. They get black mold, and pout, underpot the plant until it is actively growing, stick it in a semi - sunny spot and leave it alone, make sure it gets a lot of air circulation, gradually move it out into full sun, the less you fuss over it the better it will do. If out side, you may want to cover it with a blanket when you expect low temps and rain. If you expect rain cover the blanket with plactic. Take off coverings the first sunny days you have, it must have air circulation. Don't rush it, don't water it, don't look at it, don't fertilize it. If you still think you are having trouble contact us again. If you cut off some more roots be sure to also cut down some off the top stems as well, the roots will not be able to support a large top. if you cut 1/2 of the roots, cut off 1/2 half of the top as well.

Jeff if you see how I can expleain this in fewer words please let me know.

thank you norma.
yeah i live in denver which is zone5/6 so all my succulents spend the winter indoors.
i'll follow your advice and pull the plant out and remove the blackened roots. then let sit dry for a long time.
and yes, if i remove that much root i will need to hack a good portion of the top growth as it would tip over otherwise.
thanks again.
