Hibiscus Won't Bloom

My hibiscus hasn't bloomed in the 5 years I've had it. I bring it indoors for winter and take it back outside in the summer. What's wrong?

Melinda: You might want to try using a flowering plant fertilizer beginning in spring through late summer. These fertilizers contain high levels of phosphorous that help promote blooming. Also make sure your hibiscus is growing in full sun or another bright location outdoors. Limit pruning to fall through late winter. Pruning it at other times can delay or even prevent blossoming.
