1、 Soil

Fertile and moist soil is the most suitable for the growth of carambola. Generally, sandy loam is the best red soil on the surface. This soil is very helpful to the growth demand of carambola

2、 Illumination

Carambola is a light loving plant, but it also has a certain shade tolerance. Sufficient sunlight can make its growth and development better, but we should also avoid strong direct sunlight, which will damage its branches and leaves, so we should shade when the sun is strong

3、 Moisture

Sufficient water absorption can make the plant grow strong and powerful, and the fruit is also huge and full. When watering, it shall be subject to thorough watering, but there shall be no ponding storage. It shall be drained and waterlogged in rainy days

4、 Temperature

The temperature for normal growth of carambola is about 22-26 ℃, and the temperature should be maintained at about 2-7 ℃ in winter. Too high or too low temperature will affect the normal development of carambola, so the temperature should be controlled during breeding to make it grow better
