I am looking for a website/design tool to design a garden and landscaping before I actually plant. Any ideas?

It's better to use multiple websites and make your own decisions on the problem. I think it will help you more. http://www.aerogardenkit.com

There is a good free online tutorial at www.bewaterwise.com on how to plan a landscape, that includes some good tools like a landscape goals assessment, how to find suitable plants, and how to develop a plot plan. The downside is that you still develop the plot plan on paper, but it walks you through the steps in an easy to follow way. There is also a great list of 1,000 plants that you can search by color, size or sun/shade needs, and much more.

If your outdoor inspiration needs a little help, here is the tool you need. Use Lowe's Landscape and Garden Planner to help build the yard of your dreams. With our design tool, garden and landscape planning are as easy as clicking and dragging. http://www.lowes.com/lowes/lkn?action=pg&p=Down_to_Earth/GardenPlanner/gardenplansplash.html All you have to do to use it is to sign up for their weekly ads.
