here’s some exaples of cherry rootstocks.
Cherry
Mahaleb
The most winter hardy of the commonly used cherry rootstocks. Sweet cherries slightly dwarfed, no dwarfing effect on sour types. Induces early, heavy bearing. Resists crown gall, bacterial canker, some nematodes. Not tolerant of wet soils.
Mazzard
Standard rootstock for sweet cherries. Vigorous, more tolerant of wet soils than Mahaleb (but good drainage still required). Resistant to root-knot nematodes and oak-root fungus.
Colt
For sweet cherries. In heavy soils, trees are dwarfed to 70-80% of standard. Lesser dwarfing effect in other soils. Apparently resistant to bacterial canker. Relatively tolerant of wet soils (but good drainage still required). Trees begin bearing at young age.
GM61/1
Standard cherry varieties dwarfed to half-size, or about 15-20 ft. if not pruned. Relatively tolerant of wet soil. Trees begin bearing at young age. Trees on GM61/1 may be held to any desired height by summer pruning.
Zee Stem on Citation
Advantages: Allows cherry growers to use appropriate peach/plum/almond rootstocks for the planting location, precocious and dwarfing when used with Citation rootstock. Improves fruit quality.
Disadvantages: Crop managment may be needed on precocious varieties during early years. Not drought tolerant.
