Mangosteen (Garcinia mangostana) is a tropical fruit tree from Malaysia that produces an interesting fruit, which contains nutrients and antioxidants that might be beneficial for the heart, arthritis and other ailments. Two main types of mangosteens exist: purple and yellow. Purple mangosteens are very slow-growing and do not produce fruit until they are about 10 years old. However, yellow mangosteens grow faster and are easier to grow. If you can find seeds or a young plant of the yellow variety, you will be more likely to see fruit within just a few years of planting a mangosteen tree. If you live below 5,000 feet in elevation where winter temperatures never dip below 40 degrees Fahrenheit, you can grow mangosteen.
Prepare your planting area a few weeks before you plan to plant your mangosteen tree. Choose a shady area with rich, well-draining soil that has a slightly acidic pH.
Dig a hole about 2 feet deep by 2 feet around and then fill it with topsoil, chicken manure and compost. Then allow it to sit for up to four weeks and then plant your young tree.
Provide shade for your mangosteen tree for its first 2-3 years in the ground. You can accomplish this by building a simple A-frame that you cover with 50 percent shade cloth. You could also plant your tree near another tree that will shade it and then remove the other tree when your mangosteen is larger.
Spread mulch under your tree in order to provide nutrition, control weeds and help keep the soil moist.
Water your tree well two or three times each week. Check the soil moisture to make sure it is draining well and not making your tree live in constantly soggy soil.
Fertilize your mangosteen every three to four months with a diluted solution of balanced plant food, such as one having an N-P-K ratio of 16-16-16 or an organic fertilizer such as fish emulsion. Continue with this regimen until your tree is three years old, and then fertilize only once or twice each year.
Control insect pests such as thrips as soon as you see them. Insect pests and diseases of mangosteen are not common. You can control diseases such as blight and stem canker by providing sun protection and windbreaks when trees are small. You can also control these diseases with copper oxychloride spray.
