Hello! I\'m new to the gardening world, for the past year I\'ve just been excited I\'ve kept things alive! LOL I\'ve had this dragon tree about a year and about 6 months ago the leaves dropped and now I feel like its not growing quite like it should. I\'m hoping someone can perhaps tell me what I might be doing wrong, if anything. I just haven\'t seen another look so bare and droopy like this. Also, the leaves seem really thin.
