Arborist Thoughts

  • Cherished for its white flowering show in the Spring but dreaded for its poor structure, weak stem attachment and susceptibility to fireblight (a lethal bacterial disease) and lecanium scale (a challenging insect pest to manage).

  • This tree has reached epidemic proportions through over planting and by the high volume of escaped seedlings along highways, abandoned fields and unmanaged areas. 

  • Ohio added Callery pear to the Invasive species list in 2016.

  • One of the most likely tree species to fail under wind or ice load.

  • DO NOT PLANT
