I'm starting to think...maybe Grimal was smarter than we give him credit for?
I'm noticing the jaboticaba that he introduced is one of the most drought and heat tolerant varieties I have come across...perfectly suited for the Keys.
It can actually suffer if it's kept flooded too long, and it's one of the varieties that's most sensitive to rust (high humidity and rainfall) ...and if the tree is irrigated too much when the fruits are developing, they will split!
I strongly recommend the Grimal Jaboticaba for growers who are pushing the limits, in dry, hot areas, like CA, TX, AZ, and of course all of the other places in the world with similar climates.This year I figured out how to help the fruits achieve the best flavor....
when the flower buds start to emerge, you must water religiously, (not over watering, but not skimping either), keep this routine up, until the fruit is full size and fully colored...here comes the hard part...you must try to starve the tree for water, but do not let it dry out...the best way to do this, is by looking at the leaves...wait for them to slightly wilt...then water.
Keep doing this (for about 8-14 days, depending on your growing conditions, my trees in the greenhouse took about 14 days), until the fruits are finally like under-inflated basketballs...you will notice they have a very slightly wrinkled appearance, and they will be soft to the touch.
if you do this, the fruit will taste amazing...super sweet, totally different than a fruit that is picked improperly (even if they are fully colored, and sit on the tree for over 5 days, they still won't taste the same) I see so many people who have eaten a jaboticaba fruit, but didn't know how to pick them properly, or how to let them ripen.
it's a real challenge, because you are contending with all the animals...they will eat them long before the full flavor is achieved...and that is why they are uncivilized, and do not deserve to raid our trees!
