Acai seeds come from the Acai Palm tree which originates from the Amazon. They must be grown only in fertile, hot weather. You can purchase these seeds either online or at a local, specialized garden store. The process for growing these seeds can be a bit tedious, but once the seed is planted the results will be well worth it. Your seeds need to be soaked in warm water for two days before planting it in warm, wet soil. Make sure you cover the pot with a lid to keep the moisture and heat in and place it either outside or next to something warm indoors. In about two weeks you’ll see a little red sprout. After about four months, the palm will bear fruit.
