I am willing to devote my entire yard to this. Trees are A-OK. I already have a Coconut tree, an orange tree, a mango tree and a Sugar-apple tree. So far, I'm thinking I will grow more Citrus, Pomegranate, tomatoes, eggplant, peppers, papaya, and banana. Any other suggestions? Any reason why I should not grow any of these? Please back up any comments or criticism with facts and references.
