How worried should I be? And how much should I doom prep?

If you have land it wouldn’t hurt to have some survival crops. Something like sunchokes (a.k.a. jerusalem artichokes, bad name because they’re not an artichoke and more like a sunflower) can grow well in a sectioned off space where they can’t spread. In an emergency the tubers can be dug up and cooked, though they’ll probably give you a lot of gas from the high incline.

Personally I love raspberries and black raspberries, which are easy to grow just don’t plant them where they can spread and run wild. It’s nice to have fresh berries!

We do have small hut with few apple trees and some blackberries that we cook from when they grow(we get plenty of apples). Planning to plant something this year but didn’t decide yet, probably tomatoes. Not sure what could grow well in soil that has clay and with low maintenance.
