Differentiating Leaf Drop
Recently I transplanted my MG-soil Meyer lemon into gritty mix, and the shock caused leaf drop. I noticed that there were two different kinds of leaf drop. The initial drop was at the end of (if my college botany memory is correct) at the end of the petiole. The short stem that connects the leaf itself stayed on, but the leaf itself fell off. Now a few leaves are falling, but the entire leaf, with the petiole(?) fall off. It's clearly the plant's reaction to conditions, but the fact that the leaf drop is different makes me believe that there are two different causes.
Thanks in advance for any help!
