I am not saying they are not respectable but are soft, can be generous with latex and I have seen trees that would make a lumberjack's heart skip a beat.
Thanks for confirming that they are soft! I really want soft jackfruit that taste intensely sweet with bubble gum aroma. Well, that as close as I can get to chempedak.
Does chempedak grow well in your climate, Mike? If i can grow one here then I would not bother with jackfruit.
As for the tree size, I grew up in Indonesia, and I went to the villages in Java a lot. We ran around picking up rambutan, ketjapi, and sometimes mangoes too off the ground. Those trees were never trimmed, so they are huge. But I recall the jacfruit and durian trees were relatively on the small side, about 5-7 meters, rarely reach 10 meters. Back then, they did not have dwarf jackfruit or dwarf durian. These are all generic trees.
So the villagers keep trimming jackfruit and durian trees, because if they let the trees grow huge, it would be dangerous when the fruits drop. A ripe regular size jackfruit or durian would easily kill a pedestrian if it falls off. Also for the purpose of easier harvest, I guess.
As for trees with small and harmless fruits, they let those grow huge and just picking the ripe fruits off the ground.
