Pear trees are fruiting trees that produce sweet, firm fruit annually. Pear blossoms only remain on the tree for a short time and they do not produce very much nectar, making them less attractive to wild bees. Pear trees are partially self pollinated, but should be cross pollinated in order to produce a better harvest.
Make note of when the pear blossoms are beginning to open. In order for the trees to successfully pollinate, at least two pear trees are necessary.
Rent some honey bees when the trees are blooming 1/3 of the way. Bees are available from a vendor.
Place the bee hives equidistant from the trees and keep them there until the tree's blossoms are beginning to fall from the tree.
