The couple that plants together stays together? Who knows if that's true, but the sun is out and the birds are chirping -- unless you're here in New York, where it's dreary, but we're hopeful -- so it's high time to get outside and do something fun and useful. Some easy plants to start with, especially if you have limited outdoor space -- hello, New York again -- are tomatoes and basil. Of course, if you can eat the fruits of your labor, that's an added bonus. And, growing your own fruit and vegetables is a sustainable practice that is great for the environment.
