Hello Paul!
Thanks for your reply. The tropical trees I have in mind are mango, papaya, jack fruit, banana, coconut, neem. The climate of the place I have in mind, in south India, is hot and humid. I have read that this place used to be the home of a rain forest 300 years ago; now it is either barren land or concrete jungle
My husband and I plan to work in this area on a reforestation project.
