Yes, but a tree bearing fruit is not proof of suitability for long-term handling. Check the source, growing cycle, harvesting and actual shell and surface condition. Hetaobiaomei retains selected naturally formed walnuts from large old grafted trees after inspection. The separate wild-versus-grafted guide covers the broader comparison.
