Can you snap a picture?

Depending on the specifics of your plantings (types of plants, location and size of beds, etc), it sounds like raised beds or berms might be something to consider. A lot will also depend on drainage. If you are on rock, you may have very good drainage. If it's just hardpan soil, you may have poor drainage. There are just too many variables without more info and specifics.

I would pile up leaves this fall where you want your garden beds, as much as realistically possible, maybe next when they get wet with rain sprinkle some topsoil on them and sow winter rye or winter wheat. Turn it under in spring. This way you are actually making your own soil. If there is rock down there, it may be the only way. If it is hard-pan clay, can't hurt either, it will be easier to dig in spring. I had to do this in my yard and after a few years people admire the soil where I did it - where I didn't it is still red clay. My additional important reason was that my place is very steep - can't really dig for geometric and erosion reasons.
