ʻUlu, also known as breadfruit, is a member of the Artocarpus family. This remarkable tree thrives in tropical environments and has been cultivated for over 4,000 years. In Hawaii, ʻulu holds significant cultural and nutritional value, as it was one of the original crops brought by Polynesian voyagers on their canoes. Remarkably, just 1-2 ʻulu trees can produce enough calories to sustain an adult for an entire year.
Beyond its impressive yield, ʻulu is a versatile food source, rich in vitamins, minerals, and fiber. It can be enjoyed in various ways—baked, boiled, or even made into flour. As interest in sustainable agriculture grows, the importance of ʻulu is being recognized not only for its historical significance but also for its potential to contribute to food security in modern times.

ʻUlu, or breadfruit, is not only a staple in Hawaiian cuisine but also an emerging player in sustainable agriculture. For those considering cultivation, the investment returns are promising. With an Internal Rate of Return (IRR) ranging from 7-9% for a 5-acre plot, you could see an annual net income of around $14,000 once your trees reach maturity. Most productive sites break even at approximately 15 years, and with proper care, they can remain fruitful for over 30 years.
When planting ʻulu, a spacing of 30 feet by 30 feet allows for a remarkable yield of about 14,000 pounds per acre. This substantial output positions ʻulu as a viable option for agroforestry, where it can be integrated with other crops or livestock, creating diverse revenue streams. In fact, agroforestry practices can elevate your investment potential, with an IRR of up to 22% over a 30-year period, allowing you to break even in just 6 years.
Investing in ʻulu not only enhances your financial portfolio but also contributes to sustainable land use and biodiversity. As the global demand for eco-friendly crops increases, now is the perfect time to embrace the many benefits of cultivating this incredible tree. Explore how you can become a part of the growing ʻulu movement and enjoy both financial rewards and a positive environmental impact.

The tree can handle a wide range of temperatures but does best between 70-90 degrees. Nighttime temperatures should not drop below 55 degrees. Studies suggest ʻulu does best at elevations below 1500 feet with an optimal pH of 5-6.5. ʻUlu, or breadfruit, is a resilient tree that thrives in diversified soil, making it an excellent choice for future planting in sustainable agriculture. Ideally, ʻulu flourishes with an annual rainfall of 60 to 157 inches. While the tree can withstand periods of drought, it’s important to note that prolonged dry spells can lead to increased fruit drop, which may affect overall yields.
As an overstory crop in agroforestry landscapes, ʻulu performs best in full sun, allowing it to reach its full potential. This adaptability extends to a wide range of temperatures; however, it thrives most between 70 and 90 degrees Fahrenheit. Nighttime temperatures should ideally not drop below 55 degrees to ensure optimal growth.
Research indicates that ʻulu is best suited for elevations below 1,500 feet, with an optimal soil pH of 5 to 6.5. These conditions contribute to the tree’s health and productivity, making it a promising option for farmers looking to enhance their agroforestry systems. By choosing to plant ʻulu, you’re not only investing in a nutritious and sustainable crop but also contributing to the health of your ecosystem.
