Regarding the chicken manure: Is manure okay for fruit trees and blackberries as well? I have a free source for it very near to me, and hauled off quite a bit of it. I added ~1" to the soil surrounding my fig and sweet persimmon trees (leaving about 6" bare directly around the trunk) as well as leaves topped with wood chips. I'm not suffocating my trees am I?!
Not to worry, what you are doing sounds fine. There are some adjustments you have to make if you want to apply 'Lasagna Gardening' to our hot and humid Georgia climate. First off, that peat is going to completely decompose once the weather warms up in April. It just doesn't last as long as it does in places that have winters where the ground freezes and stops decomposition. It never gets cold enough here to shut down the soil life during the winter, so things like peat and manure just keep feeding a lively soil food web, although it may be running a little slower.
In working with wood chips, I have found that even during the 3 months of winter, you can get enough fungal growth in a pile of wood chips that they are quite well broken down to the point that they are feeding the soil. With your chicken manure/wood chip combination, your trees should do quite well in the coming spring. The blackberries too, mine get a couple inches of wood chips and lots of chicken manure tea in the winter.
P.S. You might want to look at an
updated climate zone map. Zone 7 has moved out of Georgia and south of the fall line is pretty much all zone 9.
