I live in Ohio zone 5 and bought a yellow tropical hibiscus last year while in bloom. I repotted it into a larger pot and brought it inside over the winter. Eventually it lost it leaves and looked like a bunch of sticks...but began growing leaves quite nice in late winter/early spring. When the weather warmed up I put it outside and it has turned out to be a 3-3 1/2 foot very lush foilage plant. No flowers or anything showing that it is setting any buds. I have used bloom booster fertilizer on it once a month or so. It is in a mostly sunny place in the yard (potted). Decided not to put it in direct sun since it is in a pot and was't sure if I could keep it sufficently waterd. Any advice as to why it has not bloomed? What should I have done differently?
