Here in Phoenix Citation is a dud on peaches. They massively lack vigor, im lucky to get 2-4" of growth a year when other peaches see 12-36" of growth a season. Many here have issues with Citation’s lack of drought tollerance on Apricots and Plums…I dont personally have any problems on that due to the way we deep irrigate. Its a excellent root for me on Plums and Apricots, just not Peaches.
