I was repotting a jade plant and found mold all in the bottom of the pot and on the outside of thr root ball. I know how this is caused, I just don't know what to do. Can I save my plant without using any chemicals?

Sounds like mealybugs. Try a google search. I dont know a cue without harmful chemicals, mealies are tough to get rid of. If you go with the chemical route, take the plant outside and give it a drench of orthene insecticde, available at HD.

Good Luck
