I have one jaboticaba tree that I bought about 10 years ago in Key West. I think it's a seedling and it has never fruited. I just put it in a large pot and never tended much to it. Now, I'm looking for some kind of potted kiddy pool with no drainage, then I plan to fill it with water, then put my potted jabo in it, and I plan to keep the lower one fourth of potted jabo always filled with water. All of this to see if I can get it to fruit. If this jabo is a seedling, I wonder how long it will take to fruit, if at all.
After researching the ten pages of this thread, and noticing the success some of you jabo masters have had, I've decided on a plan of action.
Because of the dissappointment had with my suspected jabo seedling, I need instant gratification. I've decided to purchase a fruiting potted jabo tree. I saw it once at a nearby nursery. It was very expensive and who knows, maybe it's more expensive now, although I hope not.
After that, I plan to purchase a grafted joboticaba of a different variety and plant it in the ground. This method is much cheaper and, two to five years for it to fruit is not bad at all. Then, when the grafted jabo does fruit, God willing, I'll then plant in the ground, the jaboticaba that was fruiting when purchased.
This plan seems to me to be a sure-proof way to finally get some jaboticabas growing in my yard. By the way, the two varieties that have so far piqued my attention are Sabara, and the blue colored one that ASaffron has mentioned that they grow almost in an everbearing fashion, from April to January.
