Thanks for the heads up on that. I'll share a close up of the soil when it arrives. I do have a soil mix for a desert rose I have, which is a succulent. It's composed of peat, graded sand, grit and loam. I also put a bit of gravel like stones at the bottom of the pot. It's got pretty good drainage as that is what it's designed for. Maybe the Jade would like the same(?)Make sure to share photos of the soil it comes in because if it looks like potting soil, we might need to recommend some triage Portulacaria is a succulent and really prefers free-draining non-organic soil mixes.
I also use a fertiliser for succulents on my desert rose; I think it's a bit more phosphorous-rich than the fertiliser I use on the bonsai. Do you think that the Jade might prefer that as well?
