The Large Coco Cream Champa had was one the removed from a customers home that was in the ground. The owner of Champa told me the lady did not like the fruit from the young CC tree so she wanted it removed. It was on Turpentine rootstock. Based on my own two-year experiment I would avoid turpentine root stock mango trees in California.
I purchased a number of Florida mango trees on turpentine root stock and thus far at my location there performance has been poor compared to the same trees grown on manila or ataulfo root stock.
The first picture is a Coconut Cream mango Tree I purchased from Florida two years ago. It is in a 20 gallon container and has grown modestly but last year I grafted a scion onto a manilla mango tree and it has taken off. On the second photo you can see the Coco Cream just flushed out and on the Florida Turpentine CC there has been no growth yet in 2017 as of the end of July.
The third and 4th photos show the Florida Sweet Tart with no growth yet while the grafted Sweet Tart on Manilla is flushing nicely now. I am only using the Florida Trees for grafting scions now and will likely sell them later when I am done with them.
