These low-maintenance trees rarely require any pruning and don't have pest problems serious enough to need chemical control methods. Fruits are fleshy, with a yellow, waxy edible peel; the seeds are edible as well. [6] They remain common in those areas and in East Asia and throughout Oceania and the Pacific Islands. [1][2] The flesh is translucent and light yellow to yellow in color. In Jamaica they are sometimes dried. Avoid overwatering your tree because standing water often causes root rot diseases and foliage health problems. Each fruit can have 10 to 12 flat light brown seeds about 6 to 13 mm (0.25 to 0.5 in) in width and enclosed in gelatinous aril. The carambola is a tropical and subtropical fruit which can be grown at elevations up to 1,200 metres (4,000 feet). ‹ › ×. [1][2], The entire fruit is edible, including the slightly waxy skin. In India, the juice is bottled for drinking.[1]. [1][3][4][5] It was introduced to the Indian Subcontinent and Sri Lanka by Austronesian traders, along with ancient Austronesian cultigens like coconuts, langsat, noni, and santol. In Southeast Asia, they are usually stewed in cloves and sugar, sometimes with apples. [1] Heavy rains may inhibit fruit production. The 'Arkin' variety represented 98% of the acreage in South Florida in the early 21st century. The carambola tree flowers throughout the year, with main fruiting seasons from April to June and October to December in Malaysia,[20] for example, but fruiting also occurs at other times in some other locales, such as South Florida. [15][16][17] Caramboxin is a neurotoxin which is structurally similar to phenylalanine, and is a glutamatergic agonist.[13]. Iron deficiency (chlorosis) on peach leaves A number of nutritional deficiencies can cause yellow leaves as one of their symptoms, including iron (as you can see above), manganese and zinc. The sour varieties have a higher oxalic acid content than the sweet type. [12] In Thailand, they are cooked together with shrimp. [20] Due to concerns over pests and pathogens, however, whole star fruits cannot yet be imported to the US from Malaysia under current United States Department of Agriculture regulations. Spread a 2- to 6-inch layer of mulch around the tree, keeping the mulching material about 12 inches away from the tree's trunk. Some of the sour varieties like "Golden Star" can become sweet if allowed to ripen. Unripe star fruits are firmer and sour, and taste like green apples. [1], Carambola trees are planted at least 6 m (20 ft) from each other and typically are fertilized three times a year. Like the grapefruit, carambola is considered to be a potent inhibitor of seven cytochrome P450 isoforms. Sometimes the fertilizers used in trees also contain herbicides that cause foliage to yellow and thicken. [7][11], Ripe carambolas may also be used in cooking. The fourth reason for yellow leaves is because of a virus disease, such as apple mosaic virus as you can see in this leaf. Plant star fruit trees at least 30 feet from other trees and structures to give the roots plenty of room to spread and allow the tree to receive ample sunlight. Harvest the star fruit when the green skin turns completely yellow, typically anywhere from 60 to 75 days after the fruit sets, depending on the cultivar. [1] Its deciduous leaves are 6–10 inches (15–25 cm) long, with 5 to 11 ovate leaflets medium-green in color. The leaves are yellowing in a weird way, it looks like a deficiency to me but I'm not sure! It prefers full sun exposure, but requires enough humidity and annual rainfall of at least 1,800 mm (70 in). [1] Moderate irrigation supports its growth during dry seasons. Water your star fruit tree regularly from bloom through harvest. Deficiency of iron, manganese and magnesium in fruit trees causes foliage to turn yellow. [1], Unripe and sour type carambolas can be mixed with other chopped spices to make relishes in Australia. [14] Consumption by those with kidney failure can produce hiccups, vomiting, nausea, mental confusion, and sometimes death. They are soft, medium green and smooth on the top with a mildly hairy underside. They may also be used as a mordant in dyeing. I'm using the miracle fruit bush to protect the yangmei, leaves touching. [1][2] They are cultivated commercially in India, Southeast Asia, southern China, Taiwan, and the southern United States. [7][8][9], Like the closely related bilimbi, there are two main types of carambola: the small sour (or tart) type and the larger sweet type. Apple mosaic virus on leaf These trees need consistently moist soils for best performance and have limited drought tolerance. Harvest the star fruit when the green skin turns completely yellow, typically anywhere from 60 to 75 days after the fruit sets, depending on the cultivar. Check with your physician about eating star fruit if you have kidney problems.

[8][10], Ripe sweet type carambolas are sweet without being overwhelming as they rarely have more than 4% sugar content. Harvested fruit stores for up to three weeks when bagged and placed in your refrigerator. The tree is cultivated throughout tropical areas of the world.
