They're extremely hard to grow inside. The humidity is a pain to try to control, they need a lot of light, and many of them need winter cold time for dormancy. They're fairly easy to keep alive outside, though. Only real general tip I have is to deadhead the flowers as soon as they dry up and don't let it start to fruit. Unless you want rosehips for your own use it takes up a lot of energy which could go into making the plant stronger.
