Hi Linda,
It seems to me that you have thought about it enough to get started. Planting and trials have to start to obtain results. If results are bad, you have learned something and do better next time.
People that have responded, have given good advice. It is up to you to use it or not. You know best what you want and what you can handle. I am not familiar with your climate. I am in 7b, which should be warmer,
If it were my place, i would plant my grapes on the south side of the shop, thornless blackberry would do great on east side of it. I would try my luck with raspberries on the west side. I would make some structure on the side of the shop, to tie them onto. I would probably spread my hashkaps around the white shop as well, because I don't know too much about them. As an alternative, I might plant the hashkaps where you intendend the fence.
The south side of the white shop should be a good place for a future greenhouse as well,
if you can level the ground. Extra runoff ftom the roof, would be a great opportunity to irrigate the greenhouse.
The zones that you have no use for now, I would definitely use to plant trees from seeds. Planting trees from seeds is easy, and it takes them a long time to produce. I can imagine zone E for nut trees. They will be on the shady side of your house, but will grow tall, probably taller than your house, so they will catch enough sun anyway. I would first create a visible line. Sticks or poles with a wire will do, but maybe you don't even need that. I would create a compost row (not heap), to prepaire the soil. Every (other) day, I would walk up there and slide aside some of the compost to plant my apple cores and fruit kernals, and dump my kitchen waste on the other end of the row. I would plant the seeds/cores every 10cm. If I could get my hands on something special, like chestnuts, or hazels or another nut, I would plant them on the on the north side of this row, or intermingled. If I had only a few, I would space them wider and mark them with a stick. I would not bother much with it all and let nature do the work. By the time you have more time on your hands, you will have so much more experience and confidence and recipes. If the line gets you nice fruit, you can cut away what does not. If there is nothing nice, you have firewood, or your kids have a nice spot to play wild. In the mean time your nut trees are still growing in a healthy eco system.
Good luck with your dreams and plans, don't forget to have fun doing it all. Keep us posted.
