Make sure you are not overwatering. Soil should be slightly dry before watering again. And they need plenty of sun. Do you have it inside or outside? They prefer to be outside, except when the temp drops below freezing. Their natural habitat is tropical areas of intense heat and low rainfall.
They are heavy feeders so either use a balanced (10-10-10) water soluble fertilizer regularly or a slow-release fertilizer twice a season.
