The property already had two gardens on it when I got there. Since it is steep and hilly, one of them is terraced into a hillside. This will make watering it easy. I will install a perforated drain pipe above it and disperse my waste water (gray water) into the garden. Must use biodegradable soap when washing hands or dishes.
The garden is mostly overgrown. Need to do some serious weeding. The soil is poor here, mostly clay. Need to add a lot of aged compost and sandy loam.
What is here right now?
8 kinds of berries: two species of blackberries, salmon berries, strawberries in the garden, raspberries, and huckleberries, among others.
Several fruit trees. Plum, apple, cherry. They are very small and not producing fruit for a few years yet.
Mushrooms! Morel mushrooms grow wild here. I will be inoculating logs with more mushroom starts. This is an ideal place to grow lots of mushrooms.
What's to come?
The obvious first choice is potatoes. Mark Watney did it in the Martian. You can grow potatoes basically anywhere on the planet, including unfarmable land. Potatoes are a complete food, with all the amino acids. Lots of calories in a little space.
Beans, corn, more fruit, and other stuff that can be preserved.
Aquaponics. This is hydroponics combined with fish farming. Being that we can't heat the system year round, we will be raising cold water fish. Probably trout. And it will be shut off and drained by the time the weather is freezing. We will have to harvest all the trout and preserve the meat. Anyone ever home canned fish before? It's amazing. We did smoked salmon one year and it was TO DIE FOR.
Aquaponics lends itself to "wet vegetables" such as lettuce and tomatoes. Lots of salads in the summer.
Maybe chickens, much later. Chickens need fences and guard dogs. We have coyotes, weasels, raccoons, and other critters that eat chickens and eggs.
