We have a HUGE (taller than the 3-story house!) Maple in the house yard, before you get to the garden beds.
My garden area gets full sun from about 11am until sundown due to that tree, but nothing seems to suffer at all from a shady morning. It’s PERFECT for morning watering in the high heat of summer, that’s for sure!
Got a true White Oak 30-40 foot to the Northeast side of where the high tunnel's going. Will make for some morning shade on one end of the tunnel about like your maple does. Got trees to the West that will cut off sun at 3-4pm in mid Summer. Other than that, going for 8-10am morning sun for growing things but will have plenty of shady spots.
I had to cut enough trees down right off the bat when we moved here to get the solar panels to work. I'm still cutting towards the East and South and leaving a few nice ones dappled in. The South will eventually be a view of a ridge 1/4 mile away that's got mixed pine and deciduous trees on it. Always has some green and has decent Fall foliage.
Something like this but with nicer shaped trees.(and a house and garden)
The pic is typical MO Ozarks and I probably have that much land but flatter and as much land that's heavily sloped and rocky land with a wet weather creek.
