Seeing so many of them in Ireland, I remembered my mother has one in a pot at home, but it's not doing too well because she doesn't know how to take care if it. I noticed that they grow in bushes or on fences, but I would really like to know how to plant it, how often to water it, where it grows best (outside or inside?). Can you plant them in pots? Do they need something like a fence for support?

I would appreciate your answers!

Thank you!
