I forgot to post a picture.......is that what this REALLY is? A baby jade? I know they're are different types but it doesn't really look like my other jades.

This is indeed a jade; there are forms that are tubular like this. I believe it is called 'Gollum' jade. That rot you can see at the bottom of the plant is a concern; those stalks that obviously have rot will continue to deteriorate as it spreads. It can be tricky to keep it from spreading throughout the roots to the rest of the plant. Personally, if I spot rot, I like to remove whatever part of the plant is healthy, re-root it and start over.

In terms of watering, you definitely want to hold off. It doesn't matter what kind of mix you have replanted into; the issue is that roots (especially small ones you don't really notice) tend to break during repotting, no matter how careful you are. If they are not able to callous before being exposed to water, rot can set in, and eventually spread throughout the root system and onto the plant. I always wait a minimum of a week. If the plants came from an over saturated mix, I wait longer. Since plants should be sheltered from direct sun and heat during this readjustment stage immediately after re-potting, there's not a lot of risk of the plant becoming desiccated from lack of water.

Hope that helps!

Thank you! I appreciate the advice!
