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® 5

(148-2 cv.) U.S.P.P. #9622

A popular introduction in Germany, this rootstock produces a very precocious tree approximately half the size of trees grown on Mazzard rootstock. It produces an open, spreading tree with wide angles. It is quite virus tolerant and does well in heavy soil. Trees grown on Gisela® 5 may need to be supported. Some suckering may occur depending on growing conditions. It is very hardy and produces well. It is compatible with most varieties. It has shown good results in Washington State.

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.
