Want to neglect fruit/nut trees and get results-what species?
Hi, I'm in zone 7 semi-inland hills of northern California. There is a bit of fog, and redwoods down in the river bottoms but I'm at about 2,000 feet, so it's dry and hot all summer. I'm looking for a genus(and species) of fruit/nut trees that can be planted and left without water(once established) and still produce. The soil varies, some acidic, some rich, some rocky, and clay.
I've seen a walnut tree planted in rocky soil at the neighbors that produces great walnuts without being watered, but most of the fruit trees I've seen in the area don't do well without water.
How about apricots?, Jujubees?, olives would be nice but I'm not sure if it gets hot enough, like inland 20 miles to the eats does. Can anybody point me in the right direction of some plants that will be at home here?
