I recently found this neat website called the Gardeners Supply Company that provides help with planning your garden layout; and best of all, it’s free. The site gives you an option to plan your own garden, or you can use one of their preplanned gardens already setup.
This site also provides advice about indoor and outdoor gardening, pests, composting, landscaping, and backyard habitat.
There is also several reference directories and encyclopedias to assist with your garden needs.
Check it out; I think you’ll enjoy using it as a reference to better assist you with your gardening.
