I bought two gorgeous Hibiscuses at the SF Garden Show today and I am not sure how to prune them. The first is a tall one and I was wondering if I should just prune all 3 braches back to help it branch or maybe train it into a tree?? I just don't like all the bare spots on the bottom(unless I go the small tree route). The other one is much shorter but the branches are at weird angels. I would like to maybe keep it on the smaller bushier side. I am not shy about pruning but don't want to mess them up. Also, I would love to root some. Do they root easily from cuttings?
