Q.Old ( 20 Years ) Jackfruit Tree Is Not Bearing Fruit
We bought a new house and there is an old jackfruit tree that’s around 20 years. According to the neighbors, it used to bear good fruit many years back, but it was left abandoned for many years and it is not bearing any fruit now. After we bought the house, we see many new leaves growing on the tree, so I don’t think it’s dead. But its barks outer layer is dark and flaky and can be peeled off quite easily in some places. I’m not sure what’s wrong with the tree. Can someone help?
