I water it deeply once a week, it has a few cedar trees as a windbreak, I fertilize it in March,April,May, and September, The Landscaper thought it was a brilliant idea to plant it near some decomposed granite! I believe i use an organic mix bought locally, I also put some slow release nitrogen fertilizer, and due to my time i cannot send you a photo. it was not root-bound when i bought it. The original soil is clay, while it guts at least 8 hours of sun
EDIT: The variety is Hak Ip, or Taiwan Black leaf
