australian bush cherry
I have repotted and cut back hard the roots on a brush cherry about 2-3 weeks ago. It seems to start pushing new leaves so it is apparently ok. I am on a frost free area.Does not look like any of the Aussie species but there are a number of South American Myrtacea species - Eugenias and probably others. New ones still being described and named.
The leaves on this one appear to be much more narrow than any of ours.
I normally repot myrtacea species in summer when possible. I am told that in frost free area they can be root pruned any time of year.
