If you read this article: https://www.lowtechmagazine.com/2020/04/fruit-trenches-cultivating-subtropical-plants-in-freezing-temperatures.html
Scroll down and you see a tree that just a foot or two tall, with the branches splayed out to keep it low for frost protection. Putting flat rocks as mulch under it would help reflect up daytime heat in the evening.
I've got 4 baby lemons I started from seed with the intention of trying this system. I'm on Vancouver Island, BC, and there are people that grow lemons here with protection, but I'm not sure how many survived this past winter. At least if it's low to the ground, putting something over it when the weather is outside of the norms is possible.
