I am not a fan of GROWING the Portulacara, however I greatly appreciate them when they are done well as Bonsai. I don’t think there is anyone better than Jim Smith at this and his trees are legendary. That is one tree that looks fake when done as a bonsai just because they are so perfect. I have tried a number of times to grow them but on my watering system everything gets watered the same. Dwarf jade don’t like a lot of water and the last tree I had developed root rot.
So I sent my Dwarf Jade to Roger’s Nursery for a ”vacation” and while it was there Mike took the liberty to cut my tree into two halves (top and bottom). Although the bottom was rather rotted out, the top was a great tree. I’ve been growing it for a while now and keeping it off the direct water spray and it seems happy. I’m trying to find some “before” pictures, but here is a current view.
