Jades are tough, so it can be revived, but it's hurting bad if it dropped as many leaves as you say. I and other jade aficionados here use a "gritty mix" for our plants. The term can be used loosely when speaking about A gritty mix, verses THE gritty mix, if ya smell what I'm cookin'. If not, search this forum with the term "gritty mix" and you'll find details on Al's (Tapla) recipe for it. People have had great success with his recipe. I, as well as others, have altered that recipe over time with different ingredients, but the principle of the mix is what is most important. What do I use you ask? Well, my mix until this summer, was an equal mix of turface (screened at 1/16") and #2 cherry stone chicken grit. This year, I've altered it into 2 parts chicken grit, 1 part screened turface, and 1 part red lava pebbles (screened at 1/16" and 1/4"). This mix is not only providing good drainage and aeration, but it looks good too. I'll post a pic of it in a bit, so I don't lose all the jibba-jabba I just wrote. Joe

I find jade roots to be generally fibrous and brownish too. Here's a good article, despite it's boring appearance: http://www.botgard.ucla.edu/html/botanytextbooks/generalbotany/typesofroots/

In case root ball has any dead-dry, damaged-broken or mushy-rotting roots, they should be cut off. It isn't traumatic for plant, it actually helps. Trimming roots is often suggested, if needed. May I ask how do you know it is already growing new roots? Or are you saying it was growing them before you re-potted? How much lower did you potted plant comparing to before? Some 'lifting' of plant is usually no problem. If any of my plant has nice, thick and almost woody root very close to surface, I often keep them exposed. Sometimes, too much of trunk could be under soil, and potting plant little higher should be no problem. But nothing should be overdone. Any pot should work, in general, as long as potting mix drains well and there is a drainage hole in it. I just re-potted my Skinny fingers from small terracotta (it was in it for more than 4 years!) into plastic of better size. Please, post photo again, we like to see what is talked about. Karen already suggested how to do it, photo icon (try Photo or Houzz Photo) is just below text box.

From both photos, the leaves doesn't look like it needs water. When you start to see small wrinkles on the leaves, then you can water. Some of the leaves will turn yellow and fall off which is normal if it was exposed to the cold for a period of time. The ones that are slight yellow will not turn back to green, just wait for it to fall off. You should be able to see some new growth in a few weeks. Your plant looks healthy. Cheers
