Papaya (Carica papaya) Profile
The papaya tree (Carica papaya) is a tropical fruit native to Mexico and South America. It is now found throughout tropical North America and other tropical parts of the world. There are many varieties of papaya, but the main varieties grown in the United States are Red Lady, Maradol, and various Solo types. To grow papaya successfully, you need a frost-free climate, plenty of sun, plenty of water and good soil. If you give your plants all these conditions, then you can grow papayas from seeds, which usually bear fruit within six to 12 months.

Papaya (Carica papaya) Distribution Area

Papaya is a soft tropical fruit with a yellowish-orange color. This species of fruit — which belongs to the Caricaceae family — is round and plump and comes in larger and smaller sizes.
It's believed that papaya is native to tropical America, with early origins in Mexico and South America. The fruit was brought into the Caribbean by indigenous people, and eventually made its way to Europe and the Pacific Islands before being introduced to Hawaii in the 1800s. Today, Hawaii is the only U.S. state to commercially produce papaya. Most papayas are from either Hawaii or Mexico. Mexican papayas can weigh up to 10 pounds (lb) and grow more than 15 inches long. Hawaiian papayas are smaller, averaging about 1 lb.

How to Grow and Care for Papaya (Carica papaya)

How to Grow Papaya (Carica papaya)

  • With Seeds
Most papayas are grown from seed because of the impracticality of vegetative propagation methods in nursery production. Seeds are extracted from fully ripe fruit, washed to remove gelatinous material and planted several per pot of soil or potting medium. Seed can be obtained from papaya fruit purchased at the local supermarket. If the fruit is from Hawaii, the chances are good that the resulting seedlings will be mostly bisexual. Germination is accomplished in approximately two weeks under full sunlight.
Steps for Papaya (Carica papaya) Propagation with Grafting
Pawpaws can generally be grafted with success using multiple grafting and budding techniques. Take scions in the winter from dormant trees that are 2 to 3 years old and graft them onto other pawpaw rootstocks.
  • With Cuttings
Propagating pawpaw trees through cuttings is possible, but it does not have a particularly high success rate. If you want to attempt it, take softwood cuttings of 6 to 8 inches (15-20 cm.) in late summer. Dip the cuttings in rooting hormone and sink them in rich, moist growing medium. It’s best to take several cuttings, as the success rate of rooting is usually very low.

How to Care for Papaya (Carica papaya)

  • Light
Full sun. Give your papaya tree as much direct sunlight as you can year-round. Moving it outdoors for the summer will help the fruits to ripen. Turn the plant a quarter turn every week because it will tend to grow toward the light source.
  • Soil
Papaya plants grow and fruit well in many well drained soil types. Plants will do well with care in sands, loams, and rocky soils with a pH of 4.5 to 8.0.
  • Water
Watering is the most critical aspect in raising papayas. The plants should be kept on to the dry side to avoid root rot, but also need enough water to support their large leaves.
Temperature and Humidity
Papaya thrives best under warm, humid conditions. It is generally intolerant of strong winds and cold weather.
  • Fertilizer 
Feed monthly and adjust according to the plant's response. They can take fairly hot organic fertilizing such as chicken manure if used with deep irrigation after warm weather has started.
  • Pruning
Papaya plants are not pruned because their main growing point is terminal, and branched trees may not produce as well.

Papaya (Carica papaya) Harvest and Storage

Papaya fruit may be harvested green for use as a vegetable and ripe when full yellow to orange color develops on the peel. Generally, fruit may be picked when yellow color covers 1/10th to 1/3rd of the surface peel, however, greater color development of the fruit while on the tree increases fruit sugar content. After picking, fruit should be placed at room temperature to fully ripen before being stored in the refrigerator. Ripe fruit will keep up to 4 to 7 days.

Uses of Papaya (Carica papaya)

Culinary. Grown throughout the tropics for the edible fruit.
  • Medicinal
In some areas, papaya leaves are made into tea as a treatment for malaria but it is not proven to be effective.
  • Edible
The fruit, flower buds, seeds, and leaves are edible. The ripe fruit can be eaten raw, without the skin or seeds. The unripe fruit can be eaten cooked, usually in curries, salads, and stews.

Papaya (Carica papaya) Common Pests/Diseases

Root rots can cause rapid death of papaya plants. The only solution is to set new plants in a better location with better drainage or use raised beds. Watering must be done with care.
Virus diseases are quite common and uncontrollable. They normally cause vein-clearing and yellow mottling of the leaves. Other symptoms include distortion of leaf growth accompanied by stunting, poor set and the presence of various greasy-appearing or yellow rings on leaves and fruit. Infected plants should be removed and destroyed.
Anthracnose appears on the fruit as irregular, water-soaked spots that later enlarge, darken and become sunken in the rind. Copper sprays have been of limited effect in severe situations, but would not be expected to be of much use under normal conditions in Texas.
Common whitefly is about the only insect pest which has affected papaya in Texas, leading to sooty mold on the foliage and fruit. Sweetpotato whitefly also is reported to favor papaya. The safest control is through spraying with a soapy water solution.
Tip burn and marginal necrosis (browning) of the leaves is caused by saline soil and water conditions common in much of Texas. Symptoms are usually more severe on older leaves and during the summer.
