Guarana (Paullinia Cupana) is a climbing shrub in the maple family that is native to the Amazon regions of Venezuela and Brazil. It forms a berry that contains the same chemical constituents as caffeine. Guarana is made into a popular soft drink said to increase energy and promote weight loss. Some guarana products are mixed with ephedra, also known as ma huang–studies have implicated this plant in health problems such as increased blood pressure. If you want to try guarana in its purest form, you can grow your own if your climate is warm and humid year-round, never dropping below 65 degrees Fahrenheit.
Soak guarana seeds in tepid water for 24 hours before you plant them.
Fill small nursery pots with standard potting soil, water them well and then poke two or three holes (half-inch deep) into the soil of each pot. Drop one of your soaked seeds into each hole and cover with more potting soil.
Keep your pots in a warm, sunny area and water them every day until you see germination beginning to occur.
Transplant your guarana seedlings to their outdoor location when they are 2 to 3 inches tall. Test your soil with an inexpensive soil test kit to determine the pH–guarana needs an acidic soil with a pH of 4.0 to 6.0. To raise pH, add hydrated lime; to lower it, add organic sulfur.
Fertilize your guarana every other month with hydrochloric acid to keep the soil acidic.
Provide a trellis to support your guarana because it will grow into a sprawling vine. Prune damaged or broken limbs when your plant gets larger.
