@don is it possible too damp? Rooted cuttings are rather cranky about that and citrus in cold weather even more so. If you can keep it alive until spring, you can graft some scions onto a good root stock. You might have better luck after that.We were getting a ton of rain earlier this fall/winter and some of my yuzus were yellowing and dropping leaves so I moved them into the greenhouse (only watered once since then) and they’re doing better.
