As for most fruit trees, a pear tree of a certain variety generally needs another pear variety to act as a pollinator. In general terms, it is best to choose a variety that blossoms at the same time, so in the same flowering group in the table below, or in the group immediately before or after. So, for example, if you wish to plant the pear variety Winter Nelis (group C), you could choose Invincible (group B), or any one of the various group C pears such as Beth, Conference, Packham’s Triumph etc., or a group D pear such as Beurré Hardy or Doyenne du Comice.
Conference and Concorde are genuinely self-fertile, while partially self-fertile trees perform better with a pollinator. If you don’t have room in your garden for two pear trees, take a look in the surrounding area: as long as there is a compatible pear variety in the immediate area, the bees will be able to pollinate your tree.
Pears are particularly sensitive to frost because they bloom fairly early in spring, when bees are less active and blossom is vulnerable to spring frosts.
The mechanisms of pear blossom pollination are similar to those in our apple pollination section.
