General notes;can be harvested mechanically, although some fruit damage may occur. Pits are longer than average, so pitting machines may have to be adjusted. Not recommended for peach or Citation rootstock as the scion and stock do not bond properly. We recommend that you use Marianna rootstock for this prune.
