I bought a hardy hibiscus in late July and it hasn't had any new growth and all the old growth is changing colors like trees do in the fall. They turn yellow, get crispy and fall off. I live in a zone 5 and my soil is mostly clay/sand. My hibiscus doesn't get as much full sun as it should. Would it be ok to move it now before winter? Somewhere with more sun and better soil or leave it and move it in the spring?
