Parker Pear Tree
Thank you for the question. Parker pear is somewhat self fertile but will produce a larger, more reliable crop with another pear tree close by. Options for pollination are Summercrisp or Patten, with Summercrisp being preferred due to its resistance to fireblight. Here is our publication on growing pears in the home garden: http://www.extension.umn.edu/garden/yard-garden/fruit/pears-in-home-garden/
