Each time we peruse the farmers' market, we dream about growing those gleaming heirloom tomatoes and fresh greens ourselves. Unfortunately, the only plant we've ever managed to keep alive was a cactus.
All you need to get planting is a zip code. We plugged ours into the sign-up section and received a list of late-summer crops like arugula, kale and radishes that will thrive in our region--the Northeast--by fall.
Specify where you want to grow your greens--a windowsill, a rooftop, a backyard--and you'll get a digital layout plan and customized calendar that tells you when to pot and water. You can purchase all of your supplies and seeds through the site (it has more than 700 varieties) and sign up to receive to-dos, like watering times and weeding tips, on your mobile.
