Like a number of other people on this forum, I have observed that Jackfruit trees seem to be stunted by grafting. The only exception I ever observed to this was at the home of the late Wayne Clifton. He had a 2yr old grafted Jackfruit that was growing as well as any seedling. Being somewhat shocked by this, I asked him how he did it. He showed me that the tree had a double rootstock. Apparently, he had approach grafted a second rootstock to the tree shortly after it was planted and in doing so restored the tree's vigor. Has anyone else ever seen something like this? Is it really just that easy, or did I miss something?
