In an effort to stop the spread of what is called “X-Disease” in cherry trees, Oregon State University Extension is offering Mid-Columbia homeowners free testing for backyard cherry trees.  Western X Phytoplasma is a bacteria that can live in the vascular system of the tree and clogs its system, leading to irregular fruit ripening.  It spreads through leaf-hopper insects and root grafting.  OSU Extension Horticulturalist Ashley Thompson says trees that have “X-Disease” need to be removed to prevent that spread, and it’s important homeowners with cherry trees watch for the signs as well, which is why the free testing is being offered.  For information on having a backyard fruit tree tested for “X-Disease,” contact Thompson at 541-296-5494, extension 38255 or email Ashley.Thompson@oregonstate.edu.
