You might consider Hugelkultur. After reading and researching these links, if you have any questions, post them here. Jerry has a really successful Hugelkultur bed and can offer a good deal of insight. The biggest plus is that once it's set up, you rarely if ever have to irrigate. http://www.richsoil.com/hugelkultur/ http://awaytogarden.com/hugelkultur-raised-garden-beds/ http://www.permaculture.co.uk/articles/many-benefits-hugelkultur
