Wow. Just........wow. I’m only on 1.2 acres and in the South, so I just opted for those three trees which were self-pollinating but were good cross-pollinators with each other. We also have a dwarf Elberta peach, nectarine, and late red peach that are of the same aspects, and a Keiffer pear tree. The peach and nectarine trees are beginning to fruit, but between the tree rats and the occasional late frost, we’ve only gotten morsels s far. We did plant four Northland blueberry bushes between a row of roses along the side of the house. We’re keeping an eye on them because they actually produced about a pint of berries while still potted last year, and we noticed a good growth spurt from them this spring.
I've thought about getting a multi-variety grafted tree, and/or grafts of a few old varieties I miss (Spie, Transparent, maybe Fameuse) for the old fashioned delicious which came up years ago when my parents ordered a grafted something or other (bare root) and only the stock survived. :^).
Keiffer pear! Just noticed that. Yeah, that's the old frontier prairie variety because it's so darned tough. The fruit stores well. Around here it isn't really ready to pick until deep in October. There's an old Keiffer in the yard as well, not lookin' great, but it's from the 19th century.
I too am in the south, around Wilmington. 4 of 5 blueberry bushes are covered in berries. 1 of 3 peach trees produced about 80 peaches. This is year 3 for 6 grapevines and they have quite a few grapes this year. Trying Chayote soon. I need a bigger yard.
