How to grow Parijat indoors in winter

Q: I purchased Parijat plant last year spring. It had good growth in Summer, after that I kept the plant inside the house in winter. A couple of weeks it was ok, after that the plant lost leaves. What is a better idea for growing Parijat plant indoors in Winter?

A: Nyctanthes arbor-tristis, Parijat - is a semi-deciduous plant, which means, it may lose its leaves during unfavorable conditions such as drought, cold, low light and/or humidity. In your case, the plant dropped leaves because of the stress of moving indoors that includes reducing light and humidity levels. When a tropical plant loses leaves during winter, this means it goes into a dormant stage. If this happens, you need to reduce watering and keep the plant on a dry side, water in only when the top level of the soil feels dry to touch. Do not fertilize.
Try to place the plant in a well-lit spot such as a windowsill. If the windowsill and the window glass feel too cold for touch during wintertime, you may place a sheet of a Styrofoam underneath the pot, and a sheet of a bubble-wrap between the plant and the window glass, to create an extra barrier from cold. The plant may re-leaf during wintertime; if not, it may wait until spring, be patient.
Bring it back into outdoor light when minimum temperatures rise above 65F and resume fertilizing.
