Hello everyone. Today I bought a bonsai tree at Whole Foods. I've always adored bonsai trees, but never owned one before. My younger sister had one when she was little, but it ended up dying since she didn't know entirely how to take care of it.
Since I bought my bonsai this afternoon I've been reading as much as possible about proper care for it. I originally wanted a plant for indoors. However, after some research I believe I have a Juniper bonsai, which means it needs to go outdoors as I found out. I live in a row home on the third floor in a dirty city, but I do have a decent sized deck where I've got some petunias growing in long boxes.
I've watered my bonsai, even the leaves, and put it out on the deck. My deck is west facing so in the evening hours it'll be sure to get a lot of direct sunlight. I can also leave it on the deck in winter for the dormancy period.
Some general advice I'd like to know is when should I repot it? Since it's from a general store there are stones that are glued down. I read a little about removing the stones and changing soils, but any advice as to when to do so would be greatly helpful. I can pick at the stones and loosen them or take them off entirely. The pot is black plastic. Not the best I know, but for now that is all I can afford to keep. I'll try looking around for a different pot soon though.
Also, when should I prune it? From looking at several photos I've noticed that Junipers can go either bushy or minimalist with the foliage and look amazing.
I took a couple photos to show, and please correct me if I'm wrong about the type.
