Oh honey - that poor thing! Look how tall it is and how short the pot is. The tap roots must be coiled up in the bottom of that pot. I would put it in the ground as soon as you can, seeing as you are in CA. I would dig the biggest deepest hole I could and make sure the soil had good drainage and some fertilizer. It might go through a shock and lose some leaves but it should survive nicely and flourish. Posting a picture is the best. I’m sure Diana or others would have an opinion too.
