My name is Emily and I live in Philadelphia.Iam somewhat new to Bonsai. I have acuired some great books and have a dwarf brush cherry, pink snow rose, and bougenvilla, which I have had succesfully for a year now. I just orderes two mini three inch starters, an azalea chin san, and an Acer plumera maple. I would like to try root over rock with one of these varieties. Wold one be easier? Or look better than the other? I have read the basics on this and know I have to grow out the roots for at least one year. I was just wondering if anyone had any tips for me on the easiest way to do this. I also know these are outdoor variety but I live in an apartment and will keep them indoor year round. Any tips would be greatly appreciated. Thank you and I'm happy to join!
