I have read through the specific care guid for the ficus microcarpa retusa but I still haven't managed to find the help I think I need. The tree has lasted really well for just over a month and now all of a sudden a large amount of the inner leaves are turning yellow and falling off. I am really worried because this happened to a smaller version of the same plant and now I think it's dead (the smaller one), this was a gift and I'm sure it was fairly expensive and I just want to make sure it survives. I spray it with water almost every day and I think I water it pretty regularly (maybe not enough, not too sure. Please help me save my baby:(
