Anyone have any experience growing citrus? I'm in the northeast so my dwarf lemon tree is potted and indoors. It has several baby lemons starting and was doing great. All of a sudden the leaves are starting to turn yellow and drop. I picked up lots of buds and a few lemons that had started today while I was cleaning. This is my third year with this tree (Roberta's) and it has done this in the past during the winter but not this severely. I've found that the instructions given by the grower didn't do well by this tree, infact the exact opposite of what they instructed has gotten me through the last two winters. I really love this tree and don't want to see it die. Thanks for any help.
