So I am in the Marine Corps and it is kinda hard to take care of a bonsai tree giving it proper sunlight and all while living in the barracks. I would put it up on the railing and eventually, as murphy's law suggests, it fell. I re-potted it, gave it some potting soil, and in a matter of two days the leaves are almost completely brown, where they used to be a rich vibrant green. I give it shaded sun during the day, it is pretty cool temperatures and I bring it inside when it gets dark. What do I do? How can I save this little guy?
