You’re in Shasta county, right? I used to live there! I’ll try to list some of the things that worked well…
We had blackberries, apple, pear, loquat and apricot.
Blackberries were the Himalayan thorny types that grow all over the area- I like them a lot- I don’t care about the thorns- I still like them!
The loquat grew like mad in a kind of part shade damp area near me. They were pretty huge and untended. I really liked those too. I think they’ve got a great flavor.
The Apple were some sort of older varieties and the trees were grown tall enough the deer couldn’t get them. We used a pole with a basket to pick them. They didn’t get much treatment but were pruned a bit. Pretty bomb proof.
Here in VA, I have 3 different neighbors who have a “bomb proof” apple tree. Large, old, maybe not the top taste- but pretty good- and seem to thrive on neglect. All three slightly different.
Pear (also grown tall) I had were referred to as “yellow pear”, a summer pear, and “frost pear” a fall pear. If you ask around, I bet some local people would give you Scionwood from varieties that work there. Pears are really easy to graft. The yellow pear was mostly green or maybe I just never waited till they ripened properly.
I don’t remember seeing any peach trees in my area- but I think if you check that you are getting enough chill hours for the variety - they should work. Spray copper for leaf curl. Also, I think you’d have to irrigate peaches. Same with apricot. I don’t think either is bomb proof- but they’re worth the effort.
I think pawpaw will be tough in Shasta County. mine really like humidity (I’m now on the east coast). But it’s worth a try.
Nearly every thing else I grew had to be in a fenced in and also watered at times.
I never managed to actually grow raspberries or strawberries there, though they should grow pretty well. Again- they don’t like to be dry.
Looking forward to hearing how some of the stuff you’re trying works out!
