Hello Sunny,
Indeed, after the harvest you can leave some leaves to try regeneration and start a new growth. Last season, without meaning to, and thanks to a super mild winter, I have a Lemon plant that has come back. The first layers of leaves were a bit strange. And the recovery was a bit slow otherwise. I had a nice surprise.
It's up to you to try; you can find some articles on this topic online.
I wish the best for your plant.
Happy growing!
