Pear trees represent some of the finest varieties in our finest heritage fruit collection. Pears are grafted onto Calleryana D6 rootstocks, which yield a standard sized pear tree if trained as a vase or central leader tree. In our own orchard, we also grow our espaliered pears on these rootstocks, and while they require a bit more care to train and keep down low as an espalier, they are more hardy than the fully dwarf pears, and do better in more difficult soils and drought conditions.
