I loves me Papa Pepper.

Citrus is going to get harder going forward, as the temperature will drop everywhere by like 10°, and if you freeze your citrus, it drops all its fruit.

Have you looked into "food forests". In nature, you have canopy trees, and beneath it smaller trees growin, and the vines and shrubs. And, you can choose plants that give you food. Like blueberry bushes instead of some thistle. After you get these things growing, they will often continue with little maintenance.
