Indoor Orange Tree Losing Leaves

Question

I have an orange tree that loses its leaves without being replaced by new leaves. Did not bear fruit this year and looks healthy with no sign of insects or diseases. The plant looks naked with only a few leaves remaining that are falling gradually. Please let me know what is the solution.

Answer 1

This is either caused by uneven watering or a lack of nutrients. Make sure to keep the soil moist at all times and add some fertilizer to the soil.
