Carambola is a tall bush trees, evergreen, woody, could reach 8 to 10 meters, much lower stems and branching. Carambola tree wood is very brittle, easily broken, so the folk have a saying “chicken bone fails, sa spike indenture”. Star fruit trees are planted by seed or transplants, there are up to 1.5 meters deep roots; the beam roots, root hairs are concentrated in 30 to 40 cm topsoil.
Star fruit trees bud several times during the year, particularly in the north are cold and windy winter drizzle contract but found fortune from 2-3 months, 4-5 months, but to the new young leaves out the most. After steady spring buds, begin to flower usually contract from June and lasted until late autumn, ie in October -11. During this period several waves flowers bloom contract: contract out flowers in clusters of 20 to 30 small flowers on stems and branches 1 year old; including the results of horizontal branches drooping trees arched tops, often with higher quality at all. Experience also shows carambola tree flowering period July to late autumn ripening usually the best quality.
Land suitable for tree type contract is loamy, easy drainage, porous because Khe perishable roots when flooded. Soil pH of 5.5 to 6.5 appropriate. Carambola needed water during feeding period results from June to the end of the year, because of drought will cause much loss results. So when raising fruit, star fruit gardens have enough moisture, if necessary, to irrigate. Star fruit trees to withstand wide temperature range. Large trees can withstand cold weather and sunlight damage. At a temperature of 22 to 25oC, handsome ripe fruit and tasty, so age is ripening in late autumn best. Carambola loathe direct sunlight, especially in the shade that fresh star fruit, star fruit, so intercropping with tall trees in the garden, shade from the sun is very good.
Until now it has been planted by seed, but recent Khe grafting (eye transplant, transplantation pressure, grafting) is widely applied.
Compared with the grafted planting by seed is relatively easy, but the longer the better carambola tree and fruit quality is not stable as a result pollinated seeds, which are subject to the type of flowers bisexual contract but could pollinate cross-generated particles dissociate, then planted with trees to other trees in many ways the mother contract. Star fruit tree nursery child care should be attentive spokes, always keeping enough moisture, hot sun. Monthly need watering when the plant reaches diluted stool height 50 to 60 cm, the pruning each tree shaped leaves 2 to 3 stems radiating sides, 1 to 2 months after the new planting.
Size hole: 0,6×0,6×0,6m. If poor soil 1,0×1,0x0,8m. 5x6m or 5x5m tree spacing. Deed in the shade should be intercropped in mango, jackfruit, longan …
Carambola tree care:
– Choose moist, colorful and shade: Note trimmed so that wide canopy frame, canopy branches are not evenly distributed in the sun shines on the main stem. When the big trees, the branches are too thick, you should prune the tree ventilated: Leave off old branches, branches that grow crowded, diseased branches, weak branches … proper pruning time is after fruit harvest, before flowering.
Tree big contract, itself vulnerable to radiation from sunshine cracked shells should pay attention to create enough leaf canopy cover for the trunk. Experience indicated that animal corpses buried under trees contract also gives better quality. During fruit tree farming contract, which should not be nitrogen fertilizer K, ash, lime to improve fruit quality. If fresh star fruit garden near the sour star fruit tree can occur cross-pollination makes fresh fruit decreased quality contract.
– Each year after the collection results (last year) for each of the original fertilizer 20-30kg of manure. When I was little fertilizer NPK 400-500g per plant (the ratio is 10: 12: 7 or 16: 16: 8). Fruit trees can begin to increase the dosage fertilizer 500-800g / tree (15:15:15). Note strengthening potash.
– With a large contract for more effective plant fertilizers NPK mixture 3-4kg / trees, divided 3-4 times a year. 3-4 months apart once applied.
Plant pest control contract:
No type of fungus, virus dangerous to the contract. The worm notably fruit flies, larvae of the lepidopteran, can bore into fruit and eat all the flowers and young fruits.
Harvesting fruits contract:

Deed is not nine additional categories after harvest, so do not pick green. Results easily crushed contract should only be harvested by hand, if the above is harvested by pole mounted at the top to pick muzzle.
