Hi Judith, nice plan. Plus you have a silo! If I'm reading your satellite view correctly, the belly of the crescent is to the South so the silo will shade a lot of the garden at sunrise?
I'd be thinking about using that silo's micro climates. The south side
should be protected and warmer which could allow for some USDA zone 5 plants. Arctic kiwis may climb up the silo if there's something for them to twine around. I think I heard that they fruit better in our climate if they are tricked into thinking spring is delayed. So maybe planting them on the West side? Just a thought.
Apricots can sometimes bloom too early up here so if you can locate them in a spot that gets shade in March/April to hold snowpack around them, you can delay their flowering a bit to protect from frost. I looked around my homestead 3 weeks ago and planned peach and apricot plantings for the spots that still had snow due to shadows from some spruce trees. In summer they're full sun but now they're still a bit shaded.
Lettuce can handle some shade so that bed could be tucked to the NW of the silo to get half a day of sun and not bolt in the heat of summer.
Hopefully others chime in with more input. Looking good and have fun with it!
