What is Red Jackfruit?

Red jackfruit (Artocarpus hypargyreus) is a variety of jackfruit separate from the more familiar green jackfruit (Artocarpus heterophyllus). Both are tropical evergreen trees in the fig family that can reach towering heights of 30-80 feet.

But what sets red jackfruit apart is its massive fruits that turn a brilliant crimson-red when ripe. These oval to oblong fruits can easily reach 10-25 lbs, sometimes much larger!

Inside the tough, knobby rind is a dense cluster of hundreds of fleshy arils or bulbs. As the fruit ripens, these arils shift from pale yellow to bright red, orange or pinkish hues with a soft, custard-like texture.

The aroma is often compared to fragrant pineapples with sweet, fruity notes of banana, mango and pineapple. Fans of durian may also detect hints of that unique tropical flavor too.

Ripe red jackfruit only has a brief shelf life of 2-4 days after harvesting before quickly becoming overripe. But the fruits, seeds, and even the trees themselves offer some remarkable uses.

Red jackfruit is cherished across Southeast Asia for both its culinary uses and cultural significance. The trees provide generous yields of 100-200 fruits annually once mature.

While the massive fruits can take some getting used to, red jackfruit delivers big tropical flavors perfect for juices, jams, ice creams and other treats. Locals even enjoy the seeds as a nut substitute.

Growing Red Jackfruit Trees

With their ultimate heights reaching 80 feet or more, red jackfruit trees require a good bit of space and sunlight in the landscape. Here are some key tips for growing them:

Climate and Location

Red jackfruit is best suited for USDA Hardiness Zones 11 and above. It cannot tolerate any freezing temperatures and needs consistently warm conditions year-round to produce fruit.

The ideal climate is hot and humid, similar to the native rainforest environments of Southeast Asia. Areas with cool winter months are simply too cold for these strictly tropical trees.

Full sun exposure is also required, with at least 6-8 hours of direct sunlight daily. Plant them in an open area free from shade or competition from other trees.

Well-drained yet moisture-retentive soil is preferred. Work plenty of compost or manure into planting holes to improve fertility and drainage.

Planting and Spacing

Plant young red jackfruit trees in early spring after danger of frost has passed. Space trees 30-50 feet apart from other plants and structures to accommodate their massive size.

When planting, dig a hole 2-3 times as wide as the root ball but no deeper. Set the root ball at the same level as the surrounding soil and backfill, firming gently.

Water thoroughly and maintain consistent soil moisture without oversaturating until the tree is well-established after 1-2 years.

Care and Maintenance

Once settled in, red jackfruit is remarkably low-maintenance, only requiring basic care:

  • Deep water monthly during the dry season
  • Fertilize with a balanced fertilizer formula 2-3 times per year
  • Apply 4-6 inches of mulch around the base to retain moisture and suppress weeds
  • Prune off any dead, rubbing or crowded interior branches annually
  • Stake young trees for the first 2-3 years to develop a strong trunk

Mature trees will begin producing fruits 3-8 years after planting depending on variety. The heavy 10-20+ lb fruits often require bagging or catch frames to prevent injury from dropped fruits.

Red jackfruit is generally unbothered by pests or diseases when grown in suitable climates with good cultural practices.

There are only a handful of named cultivars available, with many local seedling types grown across Southeast Asia too. Here are some of the most flavorful red jackfruit varieties:

Seminyo or Singapore Red – Large fruits up to 25 lbs with sweet, juicy red arils

Madu or Honey Sweet – A compact tree with elongated fruits and delicious, fragrant pulp

JF Gading – Early ripening red jackfruit variety with purple highlights

Tekam/Bangkok Red – Classic red jackfruit from Thailand with delightful aroma

Siding/Malaysian Red – An heirloom variety from Malaysia noted for soft, cottony flesh

DID Pandan – This dwarf variety only reaches 12-15 feet tall when mature

No matter which specific cultivar you’re able to source, growing red jackfruit is sure to be a memorable and delicious experience! Just be prepared to share your bountiful harvests with friends and neighbors.

With some patience and the right climate, these spectacular trees will produce unique fruits like little else in the world of gardening. Red jackfruit deserves a chance in any tropical fruit orchard or backyard food forest.
