Acai berries (Euterpe Oleracea) come from a palm tree that is native to Brazil and other parts of South America. They contain a powerful antioxidant that is more concentrated in the fresh fruit than in processed products made from it, according to studies by the USDA and several U.S. universities (see References). Because you probably won't be able to find fresh berries in even the most gourmet markets, you can grow your own to benefit from the health benefits. This tree can grow to 100 feet, so you'll need an appropriate environment if you plan to grow your own acai berries.
Growing Your Own Acai Berries
Start seeds in a well-drained potting soil. Plant seeds ½ inch deep in nursery pots or flats and keep the soil constantly moist. Expect germination within two months of planting. When seedlings are 4 to 6 inches tall, transplant them into 1-gallon nursery pots, using the same type of potting soil.
Plant your young acai palm into its permanent outdoor home when it is about 1 foot tall. Choose a wet, swampy area in full sun. Then dig in several shovelfuls of cow manure to provide drainage and nutrients to the soil.
Dig a planting hole at least twice as large as the root system of your young acai palm. Backfill with some of the topsoil-manure mixture you dug out to ensure that your palm will sit with its crown above the level of the soil. Fill in the hole and pat the soil-manure mix firmly.
Water your newly planted acai palm well and keep it wet.
Fertilize six weeks after planting with a balanced plant food, for example 10-10-10. After this initial feeding, give it the same food every other month.
Harvest your first acai berries three years after you plant your tree. Be sure to use acai berries within 24 hours of harvest because they are thought to begin losing some of their nutritional value very quickly.
