I really don't know what to do , this is a rare variety ( ssp ) of the aureana , has been doing great for so many years . Surrounded by 5 other varieties in the same part of the garden , all doing great , just this one is now loosing it's leaves and I don't have a good feeling about it .....I've been thinking of digging it out , look at the roots and maybe replanted in a large pot . I do some times over-water but I don't think this will affect a Jaboticaba ....
So far I have never lost a Jab. and I do have quite a few ...actually I can say they are tough and hard to kill ...
