They bloom on new growth so once it slows down the growth, it will eventually stop blooming. If you can encourage new growth on it, eventually that growth will mature and bloom. The ones that appear to flower year round are continually making new growth through the year, although they do take some time to rest at some point.

any suggestions on encouraging new growth? I am new to growing the hibiscus plant.

Thanks!

Well... you can give it some fertilizer - maybe a little bloom booster formula. If you can get it in a very warm spot and give it alot of light, it should suddenly take off.
