Lemon Tree Indoors, leaf drop
I am wondering if anyone knows what is going on with my lemon tree. I have it indoor in winter. It 'lives' during this season in a North facing bathroom. Last year I had no problems at all but lately it has been dropping leaves..some had turned brown and curled at the bottom before dropping. I watered and fed it and moved it to a sunnier position which seems to have stemmed the loss for now, but I would like to know what is causing it and if there is anything else I can do.
