In summers pomegranate plants are irrigated at an interval of 8 to 10 days while during winters plants are irrigated at an interval of 20 to 25 days. Keeping in mind the climatic conditions, irrigation schedule can be adjusted. Irrigation is stopped from flowering stage till fruiting. At this time if water is applied then the flowers shed and hence the fruit production reduces. As compared to large plants, small plants require frequent watering and irrigation interval is kept less and they are given water from time to time.
Pomegranates grow in locations with tropical and temperate climates. They grow best in areas with hot, dry summers and cool winters. Cold weather and hot dry weather is necessary for the development of high quality fruits. Plant grown under hot climate produces light colored, less juicy and small sized fruits. While the plants of cold humid climate plants produces good colored, large sized and more juicy fruits. Pomegranate plants can bear quite cold and severe heat. But temperature fluctuations and rainfall results in fruit cracking.
