Thanks for bringing this up Carrie. I have same problem and was thinking to replace my two multi Grafted Peach Nectarine on Citation. Both grew fine and produced about dozen fruits each. But now they look very sick. These planted March 2017. I am thinking to replace these with Lovell rootstock and kind of confused to wait or do it next year. I would love to hear from people who have older multi grafted peach Nectarine on Citation. I took these pictures today.
