Florida Gardeners- zone 10. Hibiscus won't bloom?

I have had it for 3 years atleast. I repot it every year and that's about the only time it blooms.

It is in a large pot, outdoors, in direct sun. It gets watered almost daily (rain). I live in Northern/Central FL. It has tons of leaves, no buds, no flowers. How can I get it to bloom?

Reply:It could be quite possible that since the increase in the pot size..that it is busy generating it's energy on expanding it's roots, instead of flowering. Report It
Reply:it needs what is called a bloom booster and they have it at home depot or lowes . just ask a clerk in the garden dept they will be glad to direct you to it . good luck .
