The achachairu plant is of Bolivian descent from the mangosteen family. It has a pyramid-shaped canopy and can grow up to 80 feet tall. In addition, it graces gardeners' yards with an orange pear-shaped fruit and creamy white blossoms. As a tropical tree, it should be grown in warmer climates in moist well-draining soil in order to thrive. Properly prepare your designated planting site in order to achieve success growing the achachairu.
Conduct a soil pH test on your designated planting site. Achachairu trees need to have a soil pH range of 4.7 to 6.6 to properly grow. Purchase a soil testing kit at your local nursery or county extension office. Dig a 6-inch hole and collect soil samples to mail off to the laboratory's address provided on the kit.
Add lime to your soil if the results indicate the soil is too acidic and add sulfur to alkaline soil. Spread either soil amendment in a 2-inch layer and till it into the soil.
Dig a hole twice the diameter and the same depth as the container your achachairu came in. These tree are extremely slow growing and take several years before producing fruit. It is best to purchase the plant either bare root or container grown to achieve achachairu harvests.
Place your achachairu plant in the hole and tightly pack the soil to reduce air pockets. Spread a layer of mulch around your tree to keep the soil moist.
Water your tree thoroughly and keep up a watering routine that keeps the soil moist. To establish healthy strong roots, slowly water around the base to direct the water deeply into the soil.
