This year we had a great crop of cherries. They did well up until they began to become fully ripe, then most of them rotted. So we picked most of them when they were lighter red but just before they became fully ripe to avoid the rot. What can we do to prevent this from happening again next year? Thanks, Randy
Is there any evidence of insect infestation? Spotted Wing Drosophila has been detected in the Willamette Valley and could be affecting your cherry crop. Her is a link from OSU Extension on SWD to help you determine this: http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/19525/em9021.pdf
Also, unseasonably warm weather this year has created early harvest cycles in many fruit crops. If SWD is not the cause of your cherries rotting early, then please respond to this email and I will put the question out to another Question Wrangler.
