For the growing beds I think you will want something terrace-like so you have a level bed that doesn't wash away. You could sink in posts and then put in boards or whatever as sides to keep your bed in place. Veggies are not my specialty but my memory is that squash is easier to start than tomatoes. Corns, beans and squash could be a traditional "three sisters" combination. Most veggies like full sun and fertile soil. Can't go wrong with some compost. I have seen strawberries do o.k. on a hill like yours.

You definitely want to terrace. Build up a flat bed, then fill the bed with good quality soil and compost. If your bed is sloped, your topsoil will erode and the water will run off too quickly.

Tomatoes and summer squash are easy, but tomatoes do require more water. Both are sun and heat lovers. That's really not enough space to have a healthy stand of corn -- corn needs company. If you like beans, snap beans are steady and reliable producers in most conditions.

Your best bet is to look up your county extension office and see what varieties they recommend and the planting schedule for your area. The extension office has a wealth of information, and it's free.

i'm doing a hillside veggie garden this year. I didn't dig down but raised the beds instead. And as suggested I'm using a tier system. I'm a clutz so each tier is 5 feet wide and 10 feet long. I did this because I wanted 2 feet for growing and 3 feet for me to walk along behind each tier for watering, weeding and so on. I have 5 tiers and 8 tires for my start. The tires are for the tomatoes and peppers because they do love the heat. And the black tires help absorb heat into the soil. The materials I ended up using for my tiers were 6 to 8 inch logs that I got from select cutting my forested land. I select cut for winter heating and use the logs the right size for terracing. I also throw branches here and there as errosion breaks. It's all very natural and country. I love it but it isn't for everyone.
