My Northstar has terrible bacterial diseases, but they look different than yours. Mine does have the clear ooze, which I believe is bacterial. Maybe the Teenage Mutant Ninja Turtles will know the Secret of the OOze? John S PDX OR

Gary, I would say the tree is in shock from its sudden change. The only concrete thing you can do at this point is to erect a shade barrier and keep it up for a few weeks while the roots adapt. Just put a sheet on the southern side with some poles to block the direct sunlight for those few weeks. Cherries are northern climate trees genetically and can have difficulty with strong sun. Scott

its dying... time to get rid of it.. and plant another ... its time to invest and divest.. and though your inclination is to invest.. i say but nay.. divest ... the best decision i made at my first house.. was the day i got rid of the last nightmare the prior owners left ... unfortunately it was 5 years later.. and i wasted a lot of time trying to save history.. i say pshaw on history.. get rid of it.. and create your own nightmares.. lol ken

crikey ... it didnt bear fruit because of the intense cold winter .. the buds were all killed.. just like every fruit tree in my yard just south of ann arbor ... of all the leaves in the pic.. is see two that are not perfect.. your tree is not dying ... and frankly.. if by august.. i didnt see a few yellow leaves on a prunus.. i would begin to suspect its not a prunus ... lets see a pic of the whole.. to decide if there is enough leaves affected to merit a discussion of a problem.. BTW.. i just had 4 weeks of drought and high heat.. my cheery tree is leafless... with that in mind.. your looks pretty fat and happy .... give us some more facts.. than just this pic.. and emotion ... drought.. heat.. etc ken
