There are three different tree types, female plants, male plants and bisexual plants. The female and bisexual plants are the only ones that produce fruit.

The best place to plant a papaya is on the south or southeast side of a house with some protection from wind and cold weather. Papayas also grow best in full sun. Papayas like well-drained soil, and because of shallow roots, growing papaya trees will not tolerate wet conditions. Care of Papaya Fruit Trees In addition to proper papaya growing conditions, suitable care of papaya fruit trees is also important. In order for papaya trees to thrive, they require some fertilizer. Provide young plants fertilizer every 14 days using ¼ pound of complete fertilizer. Fertilize older trees with 1 to 2 pounds of fertilizer once a month. Also, be sure to take a soil sample and amend as necessary. Water trees frequently for best fruit production. Mulch trees with 4 inches of wood chips to help retain moisture, taking care to keep the mulch 8 to 12 inches from the trunk. Protect developing fruit from pests by placing a paper bag over them until they are ripe.
