Wow that is one curled meyer!!! What is the potting mix like? I would check that as a matter of urgency, and check the roots while you are at it. The soil can be wet, but if the roots are damaged they will not uptake water, and that tree looks thirsty! Check the roots, let us know what they look like. Check the soil, let us know what it is like. Mist the leaves or put it on a gravel tray. Do not fertilize. Get back to us when you have checked whats going on beneath the surface.

The plant didn't come bare root, it came in the pot with the soil it was grown in. The soil is still damp. The roots appear to be light brown and not balled up.

Here's what I've done with a meyer lemon plant before. But I would wait to hear someone else say this is a good idea before you should try this, maybe I got lucky. I thought mine was about dead and I just figured what do I have to lose.

I got rid of all the old soil. Pruned the roots lightly. Cut off about 2 inches off the end of each growing point then put it in some fresh soil and just wet it enough to allow the soil to set up. I kept it out of light for 2 weeks then I set it out in light. After about a month I saw some new growth. Once I saw new growth I fertilized and let it grow. It's doing good now and hopefully next season I'll get some good fruiting. Last year I only had one lemon but it was large and tasted good as fresh lemonade. I have a little one on it now but I don't know it's chances since it's in the garage at nights and days that don't warm up past 50. So the lemon hasn't grown much this past month, it's about the size of an egg now.
