Description Stockton Morello is a more dwarfing rootstock than either Mahaleb or Mazzard. Cherry cultivars grown on this rootstock generally are somewhat smaller than when grown on Mahaleb, however, trees on Stockton Morello can still be quite large. Cultivars generally have the poorest union and greatest over-growth on this rootstock although the unions are normally satisfactory. This is the preferred rootstock for heavy or wet soils, although trees on Stockton Morello will not do as well under these conditions as when planted on good soils.
