    Although it can survive short periods of drought and frost, young trees are more susceptible, so they must be protected. This is because they are highly susceptible to sudden drops in temperature.
    Because it is a perennial fruit tree, it does not need to be planted at a specific time in tropical areas . However, in subtropical areas where it can be exposed to frost, it is recommended that it be sown after the winter season has passed, so that it can grow in a more favorable temperature and environment.
    Another tip on how to plant star fruit is that it should be planted in an area that can receive sunlight, but is also protected from the wind.

    Seed propagation or germination
    In case you want to extract the seeds from the fruit, you must cut the fruit until you find its seeds. You should choose those carambola seeds that are thick and in good condition . Remember that not all carambola fruits have seeds. Later you must clean the pulp of the seeds and let them dry .
    When the seeds are dry they become hard, so it is appropriate to soak them so that the outer layer softens and the germination process can begin . After they have been soaked for 8 to 12 hours, you should place them in a hotbed with damp moss and cover them lightly. 
    It may take 7-15 days for the seedling to sprout under favorable environmental conditions, and it may even take several months in winter. This container should be in a warm place, but away from sunlight.

    Star fruit sow in pots

    Carambola is planted in pots temporarily once it has several branches. This usually takes a month under favorable environmental conditions. 
    This should be kept in a pot for about a year and it may even take longer. It will have to be transplanted to the ground when it is of the appropriate size and strength to withstand inclement weather.
    The first thing you should do is prepare the pot to suit the carambola plant. A tip on how to plant carambola in a pot is that the container should be at least 20 centimeters long and we must make sure that it has drainage holes in the bottom.

    The pots are placed in a small greenhouse. The germination time for each seed is individual, it usually takes from one week to a month. Young borings are provided with illumination so that the daylight hours are 13 hours.

    If you have planted seeds in a common box, then when the third leaf appears, the seedlings must be planted in individual containers. Later planting injures the root system and reduces the percentage of plant survival.

    Young plants need to be sprayed with heated water to ensure high humidity.


    Advice. The fruits of star fruit contain oxalic acid. Therefore, people with gastrointestinal problems should eat star fruit in small quantities so as not to exacerbate the disease. Excessive consumption of fruits can disrupt salt metabolism in the body and lead to renal pathologies.

    Star fruit ground transplant

    This plant should be transplanted onto the tree after 1 year or until it reaches optimal conditions to withstand the local climate.
    The day before transplanting the shrub, it must be watered abundantly with water so that it resists the change of soil and does not wilt. 
    It should be noted that it should be planted in an area where it receives sunlight during the day and where it is protected from gusts of wind , either behind a wall or protected by other trees.
    You should also prepare the ground in advance to improve its drainage. To know if it has good drainage you must dig a hole of 30 cm and see if the water drains in less than 2 hours. Use sand if the soil retains a lot of moisture.
    The planting distance depends on climatic factors and the soil, but generally a 9 meter space is left between each tree. When transplanting the tree , a guide tube should be placed to protect its branches and guide its growth.

    Care, fertilization and feeding

    star fruit needs minimal maintenance. Since the plant is able to bloom and set fruits all year round, it needs a lot of nutrients. Top dressing is carried out once a quarter. Complex fertilizers are used for plants. With a lack of iron, the plant may develop chlorosis.

    The plant practically does not need pruning. Basically, pruning is done in order to form the crown.

    star fruit needs to be transplanted into a larger pot annually. The soil mixture should have a slightly acidic reaction, in no case alkaline. A drainage layer is required at the bottom of the tank to drain excess water.

    With a lack of moisture in the soil, the seedling can completely discard the entire leaf apparatus. When watering, it is important to maintain a balance, since excess moisture impairs the respiration of the roots and contributes to the formation of putrefactive diseases. The plant may die.

    The optimum growing temperature for a tree in the summer is from 20 ° C. In winter, it should not fall below 15 ° C.

    Star fruit irrigation

    Being a tropical and subtropical tree, it requires a sufficient supply of water in a range of 3 to 4 times a week . In winter, depending on the amount of rain or humidity of the land, it may not be necessary to water it. However, special care must be taken with young carambola trees in the dry season , providing irrigation that keeps the soil moist and conducive to the plant.


    Star fruit reproduction

    The plant is propagated in several ways:

    • vaccination;
    • seeds.

    Vaccination allows you to get a tree with fruits that have certain flavor characteristics. In our conditions, this is practically unrealistic. For our climatic zone, only seed reproduction is available. 

    Growing star fruit from seeds, it is impossible to predict what taste the seedling will have. Sweet or sour. The skin color can also vary from yellow-green to apricot and brown.

     Therefore, several seedlings are grown at once, and when the plant begins to bear fruit, a specimen with sweet fruits is left.

    Recent research has identified caramboxin as a neurotoxin that is structurally similar to phenylalanine, and is a glutamatergic agonist. While the levels of oxalic acid and caramboxin in star fruit are low enough to be processed safely by most of the general population, some researchers warn that the fruit and juice sometimes cause kidney damage or, rarely, failure. kidney in people with normal kidney function.
