Origin

No one really knows the Jackfruit's place of origin but it is believed to be indigenous to the rain forests of the Western Ghats, India. 2

Description
The jackfruit is the world's largest tree-borne fruit. The fruit can take on the proportions of a large watermelon and can weigh more than 80 pounds. Oblong, spiky, oddly reticulated, the fruit dangle from the trunk and major branches on stout cords. A fruiting tree presents a sensational visual impact. The fruit possesses a fine tropical flavor. The tree is stately and handsome and serves as a beautiful shade tree when it reaches maturity. It deserves to be planted on a broad scale and its popularity as a dooryard tree in Florida is soaring. 8

Leaves
The jackfruit leaves are evergreen, alternate, glossy, somewhat leathery to 9 in (22.5 cm) long, oval on mature wood, sometimes oblong or deeply lobed on young shoots. All parts contain a sticky, white latex. 1

Flowers
Male and female flowers are borne in separate flower-heads. Male flower-heads are on new wood among the leaves or above the female. They are swollen, oblong, from an inch to four inches long and up to an inch wide at the widest part. They are pale green at first, then darken. When mature the head is covered with yellow pollen that falls rapidly after flowering. The female heads appear on short, stout twigs that emerge from the trunk and large branches, or even from the soil-covered base of very old trees. They look like the male heads but without pollen, and soon begins to swell. 11
Flowers are attached externally to the male and the female fruit.

Pollination
Jackfruit are wind and insect pollinated, and generally fruit set and fruit quality is enhanced by cross pollination among different cultivars (or seedlings). 1

Male fruits emerge first and the female fruits are pollinated after emergence Pollination Hand pollination ensures development of female fruits.

Craig, in the above video, mentions that contrary to other fruit trees propagated from seed, taking 7-10 years to bear any fruit, jackfruit will produce fruit in three years.

Fruit
The jackfruit is a multiple fruit i.e., composed of the coherence of multiple flowers (Fig. 15,16). Fruit is moderately large to very large, weighing from 10 to 60 pounds (4.5–27.3 kg). A few cultivars are small fruited, weighing 3 to 10 pounds (1.4–4.5 kg) each. The skin is extremely rough and thick. Fruit skin color is green when immature and green, greenish-yellow to brownish-yellow when ripe. The inside of the fruit contains the edible, sweet, aromatic, crispy, soft, or melting pulp that surrounds each seed. Between the seeds and edible pulp is the inedible “rag". Pulp color varies from amber to yellow, dark yellow, or orange. Seeds are 3/4 to 1 1/4 inches (2 to 3 cm) long, oval; the number per fruit varies from 30 to 500. The time from flowering to fruit maturity ranges from 150 to 180 days. 1

Harvesting
The main fruiting season is in summer and fall. Some fruit may ripen at other times, but usually not in winter and early spring. 1
Mature jackfruit trees may produce from 40 to over 250 pounds (18–114 kg) per tree, depending on the cultivar, weather, and cultural practices. Trees that average 150 pounds (68 kg) per tree or more are considered good producers. 1
Harvest fruit with clippers or loppers. The cut stem will immediately exude white, sticky latex; this latex will permanently stain clothing. Place fruit in the shade until the latex stops exuding from the cut stem. 1

Culture
The jackfruit is well adapted to the hot humid tropics. Jackfruit grows well in the humid subtropical climate of south Florida along the coastal areas where there are only occasional freezes. Optimum growth and production occurs in continuously warm areas. 1

Cultural Calendar, University of Florida
A Guide to Jackfruit Cultivation, Archives of the Rare Fruit Council of Australia

Pruning
Young jackfruit trees do not need pruning during their first year. Shoot tip pruning once or twice during spring and summer will force lateral bud break and make the tree more compact. Non-pruned trees usually develop a strong central leader. During the second season, trees should be pruned to the first lateral branch, which will slow upward growth and enhance spreading of the canopy. As trees mature, upright vigorous shoots should be removed and the inner canopy thinned out at the end of the harvest season. 1
Dr. Campbell recommends to prune during the warm and humid season, i.e. Aug., Sept. and Oct., as pruning in the cold dry months will result in die-back and dead wood.
The best place for the fruit to grow is on the lower trunk. It will fruit anywhere on the tree trunk but will be difficult to harvest higher up. Remove the lower limbs to expose the trunk, you will soon see new fruiting shoots around these cuts. Last summer fruiting spurs as well as the thin, wispy spurs that have not fruited should be also be removed, they will not fruit again.

Pruning jackfruit v3

Fruit thinning
The number of fruit per tree or major limb should be limited to 1 on young trees, as heavy fruit loads have been observed to result in limb decline or death and tree stunting. On mature trees, limiting the number of fruit per major limb may enhance the quality and size of remaining fruit. 1

Fertilizing
For mature trees, fertilizer should be applied 2 to 3 times from bloom to right after harvesting and pruning. Iron applications are most effective from May to September, and foliar sprays from April to September. 1

Irrigation
A means of watering young trees should be available for newly planted and young trees. 
For mature trees watering is recommended during dry periods and is critical from bloom through fruit development. 1

Pest/Disease Page

Food Uses
Jackfruit may be eaten as a vegetable when picked at an immature stage or eaten fresh when picked at a mature stage and allowed to ripen. Immature fruit are usually 1 to 3 months old, are green and may be harvested for cooking. 1
Green, immature fruit may be used as a vegetable in cooking including soups, baked dishes, and fried. The pulp of ripe fruit may be eaten fresh, dried, or preserved in syrup or used for salads. The seeds can be boiled and roasted (eaten as a nut) and have a chestnut flavor. 1
Because unripe jackfruit has a meat-like taste, it is used in curry dishes with spices in Bihar, Jharkhand, Sri Lankan, Andhran, eastern Indian Bengali, Odisha and Keralan cuisines. The skin of unripe jackfruit must be peeled first; then the remaining whole jackfruit can be chopped into edible portions and cooked before serving. Young jackfruit has a mild flavor and distinctive meat-like texture and is compared to poultry. Meatless sandwiches have been suggested and are popular with both vegetarian and non vegetarian populations. 7
Arils can be fermented and distilled to produce an alcoholic beverage. 4

Medicinal Properties **
All parts of the plant have medicinal properties. The root is a remedy for skin diseases and asthma and the extract is taken in cases of fever and diarrhea.
The ashes of the leaves, burned together with corn and coconut shells are used alone or mixed with coconut oil to heal ulcers. Mixed with vinegar, the latex promotes healing of abscesses, snakebite and glandular swellings. Heated leaves alone are placed on wounds and the bark is made into poultices. The seed starch is given to relieve biliousness and the roasted seeds are regarded as aphrodisiac. In Chinese medicine the pulp and seeds are considered tonic and nutritious. 2

Other Uses
• The wood contains the yellow colorant, morin and the colorless cyanomaclurin. In 1955, workers in Bombay reported and a new yellow colorant called artocarpin. And the National Chemical Laboratory in Poona has isolated other six flavonoids.
• The bark is occasionally made into cordage or cloth.
• The 'rags' are very rich in pectin and are ideal material for jelly-making.
• The wood is beautiful, resembling mahogany and changing with age from orange or yellow to brown or dark-red. It is resistant to termite attack and fungal and bacterial decay and is easy to season. It takes polish beautifully. Though not as strong as teak, A. heterophyllus wood is considered superior to teak (Teclona grandis) for furniture, construction, turnery and inlay work, masts, oars, implements and musical instruments. The wood is widely used in India and Sri Lanka and is even exported to Europe.
• The latex yields 71.8% resin, consisting of 63.3% fluavilles (yellow) and 8.5% albanes (white). These resins may be valuable in varnishes.
• Roots are highly prized for carvings and picture framing. 2,4,9

Other Edibles in the Artocarpus genus:
Breadfruit, A. altilis
Chempedak, A. integer
Kwai Muk, A. hypargyraeus
Lakoocha, A. lacucha
Marang, A. odoratissimus

General
The generic name comes from the Greek words ‘artos’ (bread) and ‘karpos’ (fruit); the fruits are eaten and are commonly called breadfruit. The specific name, ‘heterophyllus’, is Latin for various leaves, or with leaves of different sizes and shapes; it is from the Greek word ‘heteros’ (different). 4
Never leave a decomposing jakfruit under the tree - nearly every seed will germinate, and having a tap root, are hard to pull up. So compost the fruit and seeds. There are other fruits that germinate under the tree if not picked up - yellow mangosteen and white sapote (Casimiroa edulis) are difficult to pull up when only a few inches tall. For hygiene, fallen fruit should always be gathered daily - eaten if O.K. and composted if not. 10
