Hi, New to the forums and I just wanted to give a hardy shout out to all you successful and working to be successful Bonsai growers out there. I received this Juniper Bonsai plant on Fathers day 2014 and it has been sitting at my desk in the office under florescent lighting since then. I water it as needed, touching the soil for dryness, I also put some fertilizer pebbles at the base of the tree. I spay the tree with water daily to keep the leaves moist and also have a pebble base that helps as well as it retains any excess water. it has been browning for that last couple of weeks from the inside out and I have been removing the loose leaves casually just by brushing my finger past them to see what falls. Also, from one of the images I am posting you can see a root springing up from the soil which im not sure what that means. I am really putting in best effort on this plant but its probably not the best first Bonsai plant to start with. If you could look at the image and give me a prognoses that would be appreciated.
