Oh man, this website is GE-NIUS! It's called Smart Gardener and it will actually make you smart at gardening. You will learn about what elements to consider when planning your garden in a simple guide -- like soil testing, sun direction, and plot size. You are also led to some suggested plants based upon the historical weather patterns of your zip code. It will also conveniently lead you into their partner online shops where you can buy your chosen plants (tho' you could just head to your favorite local nursery).
The planning part of gardening is so important, but so is the follow up. How perfect to take our love of technology and need of an email to give us a kick-in-the-rear reminder to water, add amendments, transplant, or whatever you have going on in your garden.
