Liz, you've already done a phenomenal amount of work in your new garden!
I'm not sure why some of your peonies are so far along! I wonder if you have a microclimate where they're growing?
I've not protected my 2 YUMI plants that put out leaves in the fall, and they've survived the entire winter despite temps below freezing, and multiple days with frost, including this morning!
Also, would a rain barrel or 2 be useful, to catch water for use, when your working in the garden? A small picnic tent, ( we got one from Dick's Sporting Good when we would chase our son playing soccer), with folding chairs or lounge chairs would be a great place to rest. Take a cheap cooler with ice, snacks and drinks for when you take a break.
I hope that they start building your cottage soon, so that you all will have a place to be comfortable when you're in AL!
