Can apples be cultivated in West Bengal, red & lateritic areas

Question

Temperature in winter ranges from 7 – 28 degrees celcious.

Answer 1

Special warm climate varieties of apple trees may be okay. The big issue is getting enough "chill hours" to set fruit adequately to make it worthwhile. You are in a borderline climate even for those varieties. If the temperature stays at 7C range for a long enough time frame it may work. But there may be some years when you won't get much fruit.
