Dieback on Asian Pear

Asked May 29, 2019, 5:45 PM EDT

Just noticed that top of Asian Pear and one side branch have died back. It seemed to flower normally this spring, and buds (now dead) are visible on twigs. Bottom part of tree is forming small fruits. Don't see any sign of infestation or other possible causes of dieback although this is my first fruit tree. Top 6' of tree is dead. No obvious problem observed on several other small trees in the vicinity, including another Asian pear.

Hi- it is not possible for us to pinpoint the cause(es) of the decline shown in the photos. The scenario of full bloom and normal leaf-out followed by rapid leaf browning and leaf drop often indicates a severely stressed tree that has insufficient food reserves stored from last year. This could have been caused by root injury before or after planting, diseases like fireblight, and environmental factors related to water, soil, light, and temperature.

Prune out all dead and dying wood, irrigate during extended dry periods, and monitor for signs and symptoms of problems.
