Quince rootstock is used for both quince and selected varieties of European pear.
Pears grafted on to the Quince A rootstock produce trees with a height after 5-10 years of approx. 3m-4m. This is larger than the same variety on Quince C but not dramatically so.
Quinces grafted on Quince A would reach 3.5m - 4m.
Quince A does best in good soils.
