bed designs

Doug says that raised beds take up more water but are easier to weed and manage if you have an older back. They are easier to control on soil management as well but if you're starting out - an in-ground garden is far more forgiving and easier to grow in than raised beds. Hope that's what you wanted to know. There's a bunch of articles here on general vegetable gardening and a search on the site will bring up raised beds and other vegetable articles all written over the past few years.
Good luck! with your new adventure and welcome to the wonderful world of gardening
