Hi! I don't really know much about bonsai at all, although I've been doing a bit of research about it lately. This is because I bought a little giant sequoia seedling (from the Jonsteen company). For now, I don't plan on doing much with it because it's still really young (it's about 3 inches tall). I'm just wondering, how do I start? Is there a certain type of soil that it would live better in? And also, do pot sizes and shapes matter? I still haven't repotted it yet from the pot it came in, so I just want to make sure I start everything right the first time. I currently live in Southern California where it gets pretty hot and dry during the summers.
