Also consider, these fruit may be growing off a rootstock sucker. The stems and foliage visible in the photo appear to be non-Meyer. Client's photo does not adequately show branching near the the graft union - a second closer photo might assist. If this is the issue, it could be due to dieback of the scion and gradual overtaking by the rootstock sucker. This might have happened due to pruning technique (if any was used) or drought/frost dieback of the scion 2 years ago.

thanks for input and the reminder of potentially another problem...While this wasn't part of the question, the condition of branches sprouting out of the root stock below the (almost always) graft can potentially lead to such a situation... in this casenow maybe the whole tree. Wasn't mentioned and/or considered in this request and response but from personal experience this can be a problem if the tree isn't protected from frosts and especially freezes... and the resulting branch can be quite vigorous... and in my case thorny.... if you suspect such a situation you can usually identify the leaf from such a rogue growth... and eliminate it from the tree... this is usually obvious from growth below the graft..on the other hand Meyer lemon are often grown on their own rootstock ... for a potted plant it is usually good practice to secure it in a protected environment for the winter (e.g. next to the house under overhang... just remember to water..) growing in the open, review the various recommendations of frost/freeze protection with covers

I have a dwarf Meyer lemon tree. For years was in a pot - got some fruit. This year I put it in the ground.i a large hole, new soil some amendment, little old soil. Took out almost all the rocks. Very dry rocky soil. So far it looks worse than ever. Don't know if I can take a pic. Some leaves on one side . The rest dry branches -tho bendable. Frtilized when put in ground - water once a week -ffry to depth of one finger deep. Is it practically dead? Any help? Not wet enough? Help

Thanks for responding to the blog post on "big" Meyer Lemons. Without knowing where you are located and the sun/shade situation, I'd initially venture that you are not giving it enough water, ideally penetration of the water should be to about 8", and ideally deeper but ess frequent... and placing a several inch plus mulch over the root zone (clear the trunk by several inches, but covering at least out to the tip of the farthest branches) might help. Also, all those years in the pot may have deformed the roots. Might be time for a "new" Meyer Lemon. Finally, I'd suggest reading the blog again, and especially the linked UC references given near the bottom of the blog. on the growing and care of Lemons.  
Hopefully, that helps. Please do not hesitate to comment and/or send questions again.
