Hi! I purchased a Meyer Lemon Tree last spring to be grown on my deck in a large half wine barrel container. It had small flowers and a few leaves when I re-planted it and it gave me about a dozen lemons through the fall. I live in the Atlanta area and I am now covering it when there is a stretch of below freezing temps. Currently, it has no leaves and I wanted to inquire if this is normal for my area and the time of year? Am I doing the right thing by covering it to avoid frost? It gets plenty of sunshine on above freezing days. Would love anyone's thoughts. Thanks!
