The mangosteen, Garcinia mangostana L., is a tropical tree native to Indonesia. A slow-growing tree, the mangosteen eventually reaches heights of 20 to 80 feet. Mangosteen is a challenge to grow because it requires high humidity, lots of moisture and temperatures no colder than 45 degrees Fahrenheit and no warmer than 100 degrees Fahrenheit. Mangosteen has failed to thrive in Hawaii, California and Florida. The seed should be planted directly in its permanent location no later than five days after removal from the fruit.
Place the seed in a bowl of water and allow it to soak for 24 hours.
Choose a shady location in which to plant the mangosteen seed.
Add 3 inches of compost and 3 inches of peat moss to the planting area. The soil should be 3 feet deep, so add topsoil, if necessary, to bring the planting area to the required depth. Mix all of the amendments into the existing soil.
Place the mangosteen seed on top of the soil and sprinkle soil over it so that it is lightly covered.
Water the seed with the fine-mist setting on your hose, being careful to not wash it away. Keep the soil moist until the seed sprouts, which should occur within three weeks.
