I find that some of my tropicals slow down in growth as the seasons change, especially transitioning from summer going towards and during the colder months, even if they are indoors. So I just water them to keep those roots alive, but not too wet. I do not give them fertilizer either at this time, I wait for mid to late Spring to do that. They will perk up once more by then, and grow newer leaves. It has taught me to remember that these plants are after all tropicals, and cold season is not their cup of tea. So keep that plant suitably warm and moist, in bright light but not direct sun, and it should hang on till the warmer weather returns.
