While it's not one of the main nuts grown in the United States, it's a fascinating plant with unusual fruits. Of the many imposing trees in the rainforest, Brazil's walnut (Bertholletia excelsa) is one of the most intriguing. The tree is best cultivated in the United States. UU.
Department of Agriculture Plant Hardiness Zone 11 and above. Known for requiring very specific conditions for growth, flowering and fruiting, Brazil nuts are generally harvested directly from wild trees. Brazil's nut trees are approximately 160 feet tall and, when properly cultivated, produce creamy white flowers and massive segmented fruits filled with edible nuts. Growing these trees is difficult, even if you live in a walnut growing area in Brazil, but it's also a very rewarding task.
Once you have a raw Brazil nut, you can plant it in a jar with nutrient-rich soil. Once the seeds have germinated, you can move them to a larger container. Most nuts from Brazil imported to the U.S. Undergo processing involving soaking and boiling.
Boiling kills the seed, making it impossible for it to sprout. Adequate seed stock can be purchased through online nurseries, harvested directly from rainforest trees, or obtained at specialty markets. Do your research and ask lots of questions to make sure you're getting healthy, raw nuts to plant. Soaking allows the outer shell of the seed to soften to peel it and allows the nut time to sprout.
Fill a large glass jar to one-third full with unshelled nuts and cover it for twenty-four hours. Pour in the water and rinse the nuts. Continue the process, reducing the soaking time to eight-hour increments until you see it sprouting. Once you see it sprouting, carefully remove the outer shell of the nut.
Brazil nuts require a number of very specific conditions in order to sprout. The best way to achieve most of these conditions is to prepare an environment similar to that of the rainforest. Fill an oversized canning jar two-thirds full with moist, nutrient-rich potting soil. Keep a piece of cheesecloth and a rubber band handy to cover the jar once the sprout has been planted.
It creates a depression in the soil deep enough to cover the entire seed. Cover the seed with soil and water moderately without making the soil swampy. Cover the jar with gauze and secure it with a rubber band. Place the bottle in a location with low or indirect sunlight.
Check the seed frequently for signs of germination or failed germination. A germinated seed will show signs of sprouting, while a failed germination will show mold in the jar. If the seed has germinated, move the jar to a sunny location. Remove the cheesecloth for about three to four hours a day to provide the plant with fresh air.
Once the tree develops a set of true leaves, move it to a larger covered pot so it has room to grow. Pickers harvest walnuts from Brazil during the wet season (January-March), when most of the tree fruits have fallen to the forest floor. While some specialty grocery stores sell walnuts from Brazil, there's nothing better than the convenience of having them delivered to your door. Brazil nuts are commonly eaten raw or blanched and are high in protein, dietary fiber, thiamine, selenium, copper and magnesium.
At first glance, the Brazilian nut looks like little more than an oversized, expensive nut that is overlooked in the supermarket. With some brands and types of Brazil nuts that aren't as fresh, they'll be darker, with an unpleasant taste or smell. Brazil nuts are related to other tropical trees appreciated for their fruits and nuts, such as the cannonball tree (Couroupita guianensis), the anchovy pear (Grias cauliflora) and the monkey pot (Lecythis species). Brazil nuts are mostly sold unshelled, not only for ease of consumption, but also due to safety regulations in many countries.
Brazil nut (Bertholletia excelsa), also called Pará nut, edible seed of a large South American tree (Lecythidaceae family) found in the Amazonian forests of Brazil, Peru, Colombia and Ecuador. A typical 15 cm (6 in) pod can weigh up to 2.3 kg (5 pounds) and contains 12 to 24 nuts or seeds that are arranged like sections of an orange. . .
