Cherry Rootstocks

Gisela® 12

(195-2 cv.) U.S.P.P. #9631

A precocious, semi-dwarf cherry rootstock, yielding a tree about 60% of one grown on Mazzard. Produces a tree that is spreading and open. Resists suckering, is well anchored but may require support.

Gisela® 6

(148-1 cv.) U.S.P.P. #8954

A semi-dwarf rootstock that produces a tree slightly smaller than Mazzard, roughly 80 to 90 percent. A good substitute for Mazzard, Gisela® 6 is well suited for heavy soil types. The tree structure is very open and round. Very precocious despite its vigor. It appears tolerant to many cherry viruses and is not prone to suckering. Anchors well, but may need support, especially in the first fruiting years because of its precocious nature.

Mahaleb

Performs in deep soils with good drainage. This rootstock is somewhat dwarfing, cold hardy and precocious. Deep rooted. Not recommended for heavy soils or areas with high water tables.

Mazzard

(P. avium)

Fibrous root system makes Mazzard a good choice for wet and heavy soils. Mazzard is the most popular cherry rootstock grown in North America. It is generally more vigorous than Mahaleb, especially in poorer soils.
