I have a meyer lemon which i got in the beginning of the summer. Since I got it it has doubled in size. I has several leoms on it, and lots of new growth. I live in NJ and I have just moved the tree from full sun, to partial shade in preperation to bring it inside for the winter. Prior to moving the tree, i began to notice some of the lower leaves begining to yeallow and drop. The tree is still blooming, and otherwise seems healthy. I have been told as new growth forms, some leaves will drop. Is this normal?
