If you decide to not trim it forever, and a hurricane doesn't do it for you, It can get massive 30-40 feet in a few decades. But that's unlikely. There are easier to clean jackfruit hybrids, Cenna for example, which is a jackfruit x champadek hybrid (champajack). They seem to be smaller, smaller fruit, and less latex, better tasting i've heard as well. I have a two other champajack varieties coming from southeast asia soon. I haven't seen anyone with them in South Florida. Send me a PM if interested.
