When I bought this tree, about 2 years prior to the beginning of this thread, it had just been dug from the field in California, and shipped bare root to Plant City in Georgia. There were 3 of them. I cut down three large pots, and potted each of them into 3 inch pans in Boon Mix. All lived. I didn’t cut many (if any) roots at that first potting, my goal was to get them healthy in pots. The other two were sold. I bought one.
I kept it in the cut down pan for three years until I potted it as described in this thread.
Pretty much anything I have in a pot will be in Boon’s Mix.
