I give my 15 gallon Vexators less water than any other Jabo, and that is what I have figured out keeps them alive for me , but also growing in the summer months and looking good.
Alot of the confusion in jabo tips and tricks comes from 9b Florida and 9b California being completely different but labeled the same.
One is humid, one generally arid. The low temperatures recovery in Florida is generally much faster.
The daily temperature swing is often much greater in California , it can swing 40-50 degree’s in 24 hours, that can be alot for some subtropicals and tropicals.
I love growing Jabo’s in Airpots because they dry out faster and grow faster.
If I was in FL that technique would not work.
Even inland CA in some of the hotter area’s the airpots dry out too fast and growers I talked to do not like them but for me the results are what they are and I like my Jabo’a to grow as swiftly as possible , pushing growth through as much of the year as I can.
Jabo’s have taught me alot .
I remember Adam Shafran talking about this in some of his videos. He said that jaboticabas like to be kept wet, especially when fruiting, and especially his Grimals. But, they cannot be kept wet indefinitely, or they will get root rot. I have never heard anyone recommending keeping them waterlogged continuously. The only jaboticaba that might be able to handle that is the blue jaboticaba; I believe there is a grower here on the forum who has some growing just fine next to a canal. Even that may be misleading, though, if those blue jabos are on the bank a few feet above the canal's water level, then the entire root system is not continuously waterlogged; it just has feeder roots going down to access water in the canal.
