In Australia, seashore mangosteen, yellow mangosteen, Cambogia and madrano are grown alongside the more common purple mangosteen, however they are part of a niche market. Growth and harvest Trees are slow growing and can take up to 10 years to bear fruit. Mangosteens are typically grown from seed and flourish in wet, tropical, humid climates.
Rich, deep soil with solid water-holding capacity is a must, with trees also doing well on deep river loams. Peak season in Australia is between November and March. Look for moist, firm seeds that have a tan perimeter with a white to off-white center.
Moisten paper towels with refrigerated purified water and wrap them around the seeds to prevent them from drying. Keep the paper towels moist with refrigerated purified water when in storage. Remove the mangosteen seeds from the bag and place the seeds in purified water. Allow the seeds to soak for 24 hours prior to planting. Due to increased pest and disease pressure and production costs, citrus growers are beginning to look into alternative crops to diversify and find new markets.
Some of these alternative crops might work, while others will not because of lack of adaptability to local climate or lack of market for that specific crop.
When selecting any crop, it is necessary to choose a crop that is native to a similar climate or is already adapted to local conditions. Mangosteen Garcinia mangostana is a tropical tree, native to the equator An equator is an imaginary line around the middle of a planet or other celestial body. The place of origin of the mangosteen is unknown but is believed to be the Sunda Islands and the Moluccas in Malaysia.
It is much cultivated in Thailand where it has been suggested that the tree may have been first domesticated. Because the tree is truly tropical and cold-sensitive, the best region to grow mangosteen is south Florida especially Miami Dade USDA 11a. Mangosteens can only grow in specific tropical locales that are able to provide the narrow temperature range and climatic conditions they need to survive. Known as an ultra-tropical tree, they cannot survive temperatures below 45 degrees or above degrees.
They also require high humidity and lots of water to thrive. Some commercial cultivation of mangosteens is currently in progress at lower elevations on the Hilo side. With careful attention to their needs they can be grown successfully in West Hawaii, as well. A tropical evergreen, the mangosteen has attractive thick, leathery dark green leaves that are glossy on the surface. When they first appear, however, they are rose colored; changing to dark green as they mature.
The leaves are supported on a trunk and branches with dark brown, nearly black, flaking bark with an inner bark that contains latex. After many years, the tree will support a dense pyramidal crown. Flowers, which may appear after about five years, are nearly 3 inches across and a lovely pink color with cream centers. Though the tree grows very slowly, it can get quite tall in ideal conditions. Here in Hawaii, it usually reaches about 30 feet, but that may take as many years.
Growing at about a foot a year, a two-year-old seedling may only be a little more than 12 inches tall. The trees are sensitive to salt spray and strong winds. They will grow best planted near streams or ponds or bodies of fresh water that keep at least portions of their roots moist year round.
Though they prefer locations that get more than 50 inches of rain annually, they can be maintained in west Hawaii between and 1, feet elevation in a partial shade location with frequent irrigation and a good mulch layer to retain moisture in the roots.
At maturity usually well beyond 10 years fruit may develop that forms from the center of the flower and is light green as it ripens. When ripe it becomes deep reddish purple and measures about 3 inches around.
