Williams' Bon Chrétien

The classic tinned pear, and one that must be eaten within days of ripening — it goes from hard to over-ripe quickly and will not keep. Known worldwide as Bartlett. This is also the cultivar that makes rootstock notes necessary: it will not form a durable union with quince on its own.

A cultivar of Pear. Everything on this page is about the cultivar; how to grow the species is on the plant page, and how big the tree gets is on the rootstock page.

On each rootstock

The size of the tree comes from the rootstock. What the cultivar contributes is a direction, in words — GrowingHQ does not multiply the range by a vigour factor, because no source supports the multiplier and the resulting number would look far more precise than the inputs are.

Williams' Bon Chrétien is of average vigour, so the rootstock's range applies as published.The same incompatibility as Quince A, and for the same reason: both are quince, and the failure is between the species rather than between the rootstock clones.

Williams' Bon Chrétien is of average vigour, so the rootstock's range applies as published.Graft-incompatible with quince: the union fails over time unless an interstem of a compatible cultivar — 'Beurré Hardy' is the usual one — is grafted between rootstock and cultivar. Trees sold as Williams on quince are normally already double-worked, but it is worth asking.

Full profiles for each of these are on the rootstock page.
