I have a small yuzu citrus tree which I bought this spring. It's planted in a container and seems quite healthy, but I'm starting to wonder how I should overwinter it. I know they are semi-hardy and can stand some freezing temperatures, but I'm not sure how well they do during winter in a container. Should I wrap the container? Use lights to keep it warm? Bury the container? Or just bring it inside.. any advice would be appreciated.
