Jackfruit
The world's largest tree fruit. And it grows here.
Artocarpus heterophyllus
The giant of the food forest, growing the largest fruit of any tree on earth.
Why it works here
Jackfruit is the showstopper of a tropical edible landscape, a fast, handsome shade tree that hangs enormous fruit right off its trunk and main limbs. The fruit ranges from a few pounds to sixty or more, and it is versatile: ripe and sweet, or young and cooked like a meat substitute. It is the most cold-sensitive tree on this list though, so on the Treasure Coast it belongs in the warmest, most sheltered corner you have.
Care
Give it space, full sun, and rich, well-drained soil, then water consistently through the first couple of years to push growth. Feed with compost and balanced organic fertilizer through the warm months, and mulch widely. It is a heavy feeder and a fast grower, so keep the organic matter coming. Prune while young to set a strong framework and to hold the height, because the fruit is heavy and you want reachable, well-attached limbs.
Common problems
Cold damage: leaves are hurt around 32°F and a tree can die near 28°F. This is the honest limitation on the Treasure Coast. Site it warm, keep it small and coverable while young, and be ready to protect it on a hard freeze night.
Fruit rots (Rhizopus fruit rot, gray mold): in our humidity, especially on damaged or overripe fruit. Harvest promptly, clean up dropped fruit, and keep the canopy open for airflow.
Boring insects, scales, mealybugs: on stems and fruit. Encourage beneficial insects, hand-remove what you can, and keep the tree vigorous so it shrugs off minor pressure.
Common questions
Is a whole jackfruit really going to be 50 pounds?
It can be. Fruit size depends hugely on variety, from small few-pound types to monsters over 50 pounds. If a giant hanging off your tree worries you, choose a small-fruited grafted variety.
Will it survive a Treasure Coast winter?
In a warm, protected microclimate, usually yes once it has some size. But it is genuinely tender, and a hard freeze can set it back or kill a young one. Plant it in your warmest spot and plan to cover it the first few winters.
What does it taste like?
Ripe, it is sweet and tropical, often compared to a mix of banana, mango, and bubblegum. Unripe and cooked, it is mild and stringy and takes on whatever you season it with, which is why it turns up as pulled-pork-style dishes.
