Need help to ID this tree/shrub
I need help in identifying this rescued tree/shrub. About 2 months ago I dug it out from the old lot there the small plant nursery used to be just a few years ago. It looks like it is recovering from the transplanting shock as is pushing a new growth. So, now I have two questions: what is it and what needs to be done to get it back in to the shape and fruit bearing condition. Upon transplanting, it had one small green fruit of the plum type, about 0.5 inch. Unfortunately, my camera doesn't catch a more red/purplish color on the new foliage. Please, advise, as I'm a newbie. Thank you.
