Thanks in advance for your time in answering my question, I appreciate it. This bonsai is probably two years old, and I've had it a month. I've been pinching for shape, but I've not fertilized yet and I know I should be. The needles on the inside of the plant are turning brown. Not all of them, but I can see the pattern. I was thinking I might be over watering. I'm in GA where it is very hot and the tree lives outside and gets plenty of sunlight outside around a pool deck on a spread of thyme. I wanted to get some advice before too much damage has occurred. Thanks again.
