Pollination – Pear Trees

Question

I intend planting 3 bear root pear trees in the planting season. the varieties are (1)Pear Concorde, (2) pear Williams’ Bon Chretien. (3)Pear Doyenne du Comice. Are these three capable of pollinating each other for me to hopefully get positive fruit results from all 3 trees in the future? I have been told that if I plant a John Downie crab apple tree nearby it will pollinate all the pear trees – should all or any of them prove to be self sterile.

Answer 1

Let's address the most important thing, first. Apples are in the genus, Malus. Pears are in the genus, Pyrus. Cross pollination between the two genera are impossible. Everyone has a partner, except for Concorde. The good news is that these are, partially, self fertile.

Here are some articles that will help:
