Growing Hibiscus Outside In Upstate New York
I am interested in growing hibiscus outside in Seneca Lake area of New York State. The plants would be outside year round. Would this kill the bushes or would they survive the winter weather. Also, during the summer do the plants need full sun?

A hardy hibiscus plant will survive there but a tropical hibiscus will not. Hardy hibiscus plants need little care over winter and are hardy to zone 5 with no protection outdoors, though you may add mulch if you like. The tropical varieties are the ones that require growth indoors over winter. So look for a perennial, hardy hibiscus variety. Your local garden center or nursery should be able to help with this....and yes, they enjoy full sun outdoors.
