We have a five-year old lemon tree in a pot which has always done well gainst a south facing wall. We bring it in in winter. This winter we brought it in and put it in a place where I suspect there wasn't enough light. It had grown too large for its previous over-wintering site.

It has now lost half its leaves and does not look happy. I have moved it into a ligther spot. I am wondering whether cutting it back would help or hinder.

Any suggestions welcome.
