One of the problems that urban and suburban gardeners is lack of bee activity. I plant lemon basil at the edge of my garden and the heart of my garden and draw all kinds of bee activity in my veggie patch. And when the wind blows it smells like lemons on the air. If you are lacking bees in your garden consider planting these in and around your garden.
