Have you heard of Smart Gardener? I just discovered it from Pinterest, and let me tell you, it's the best thing to happen to gardening in a long long time.
There are so many great features on this website, and it literally holds the beginning gardener's hands the entire journey of starting your garden. To sign up, you enter in your email then your zip code so they can tell you what planting zone you are in, when your first and last frosts are, and what plants are recommended for your area.
Once you've created your profile, you can map out in detail the layout of your garden. Choose in ground plots, raised beds, and containers in any size to completely customize your yard.
After you've mapped out your space, you can then choose which plants you want to grow, from vegetables to herbs to fruit to flowers. Smart Gardener will show you what to plant where, give you a calendar and to do lists to make all the stress and uncertainty of sowing, growing, and harvesting disappear.
They also have a fabulous community where you can tour other people's garden plans, find recipes for the edibles you are growing, and they even have a marketplace where they sell the seeds for you to plant in your garden!
This is a dream come true for a planner outer like me, I've spent all day on the site and can't wait to waste away weeks designing my dream garden!
