g'day missinformation,

can't see why it wouldn't work, citrus do like a mediterannean climate that is hot and dry summer and cold winters, should be plenty of books at the library on espaliering fruit trees. did you do a google at all?

I don't know much if anything about the Mexican Lime. Meyer Lemon can be pretty hardy. The in-laws have one that grows like a bush. They live near Ocala, FL. The Meyer has been damaged by cold some years there but it has survived the damage without extra protection. I'm a couple hours further south and a Meyer Lemmon tree would have no problem outside here with the current climate. We also have grapefruit, Tangerine and another unknown tree. Keep in mind that hardiness zones fluctuate over time with climate change and other factors. If you can provide extra protection if hard freezes are forcasted to happen, then keeping them outside against that protect wall may be safe. If you are hoping that the wall will be enough, you might be risking your citrus. I don't know exactly where you are other than zone 8. Espaliering a tree doesn't change it's hardiness per-say. It is the protected location that can help. Most info I've seen about espaliering was to do with more northerly trees like apples, pears, etc.

Good luck, I'm sure after a few years such trees would become too heavy to happily move indoors for the cold snaps.

Miss I: Citrus are very hardy in the right environment. Google Just Fruits and Exotics and check out that nursery's inventory and growing advice. They're about 30 miles from my farm and are real experts on small-scale fruit production. Great folks.

Hey, drop me an email if you have a second. I have some pretty cool chickens I want to tell you about, and I want to send you a few free chicks for your subversive urban poultry experiment.
