So this is the first bonsai tree I bought back in late November. Really wanted to keep it inside but everything I read said NOOOOOO so I made a cold frame, insulated with pine needles and it made it through Winter. In regards to my research amongst different bonsai trees in regards to care, pruning etc I know very little in regards to this tree. The tree is still outside and it's grown a bit over the last month the foliage mostly being very fluffy. My question is down the middle the foliage is different it's almost crisp? Difficult to explain but u can see the difference in the pictures. Is this just blocked and not getting enough light? I've also read that in regards to pruning you should pinch and something about if you prune wrong it could kill the whole shoot? I just want the tree to grow so any recommendations in regards to pruning, growth, watering etc I'd appreciate.
