I live in Massachusetts. Years ago, I went to Florida and picked up one of those ornamental orange trees at the airport. I brought it home, and for 10 years had pretty little oranges on the tree, until it died. Five years ago, I did the same thing. I went to Florida, and brought home two ornamental orange trees. The trees are pretty good size, and I trimmed them as the instructions said. In the summer I leave them on the deck, and bring them in for the fall and winter. They get pleanty of sun, Miracle Grow, and a big pot. Why don't I have any blossoms or oranges? I have nothing but green leafy trees! They are over five years old! Am I missing something, any of you "green thumbs" know about?
