Calamondin can be grown in a wide range of climatic conditions where temperature exceeds 20 °C and the humidity is high. In the highlands it can be grown up to 1200 m above sea level. At this height, the sunshine hours are shorter and the temperature is cooler with marked differences between day and night temperature. This temperature fluctuation results in the fruits developing a strong orange colour as compared to those grown in the lowlands.

Rainfall can be a limiting factor in growing citrus. Too much continuous rainfall can cause the tree to be vegetative and produce less fruits. When pommelo is grown on heavy soil, rainfall can predispose the plant to root diseases such as Phytophthora collar rot. In areas where rubber was grown prior to citrus the trees can be prone to white root disease and Pythium disease. The best soil for citrus is a medium texture soil of alluvial origin, uniform, reasonably deep and fertile, good drainage and free from injurious salts.

The planting for calamondin is rectangular or square with planting distance ranging from 2 to 5 metres in each direction. The planting distance varies with the soil type and terrain. In fertile soil the planting distance should be wider to accommodate vigorous tree growth and machinery movement during cultural and harvesting operations. This distance also encourages adequate sunlight for the trees. Row direction is preferably north-south to take the maximum advantage of sunlight.

Before the actual planting is carried out, planting holes measuring 60cm x 60cm x 60cm are prepared with an auger or manually. A mixture of organic fertiliser (5kg), GML (ground magnesium limestone) (0.25kg), and phosphate fertiliser, for root enhancement, (0.25 kg) is put in the hole prior to planting the calamondin plant.
