Here is a picture of some of the unhappy leaves.

Stop moving it.... The Meyer is particularly sensitive to significant light changes; when you subject it to that, it will drop many/most/all of its leaves to later replace them with new leaves better suited to the new light conditions. Treat it well and it should recover.

If you can get that tree into a plastic pot with a very good porous mix, it will take off!@

Ys, my meyer lemon has the same kind of leaf problem. Leaves were fine when i bought it and it has been inside the flower store. But when i brought it to home. It was very sunny day when it in my window then it was cloudy sky for almost whole week and then suddenly a lot of sun light. This type changes can stress the plant initially. I think gradually change in plants position will make difference.

Thanks for the suggestions! I will be sure not to move it again until it gets too cold to keep it outside next winter.

Four winds had said to use a ceramic pot, but after reading through all the great advice and stories on this site it certainly sounds like plastic is the way to go.

Would it be bad to try to prune this tree now so it's not so leggy? Or is it best to wait until it's less stressed? I've read not to prune in late summer or fall, so I feel like I don't have much of a window of time to do it unless I want to wait until next spring.

Four winds actually took a lot of our advice and applied it in their website, although the ceramic they did not.

Plastic will keep your roots warmer which lemon Meyer like but will not allow the kind of drainage that clay does. I would watch your watering practices and make sure not to over water more than anything. Clay is more forgiving on that end, unless of course you are using a fast drainage very porous mix.

Pruning it now will do no harm , if anything encourage new growth.
