As more gardeners grow flowers, edibles and even perennials in containers, we've become more invested in their success. Unlike in a large garden where losing a few plants isn't a disaster, there's a smaller margin for error when growing in a small raised bed or container. Charlie will show you how to grow your container plants successfully, use fertilizer appropriately, extend the flowering and harvest season, and protect them from pests and the elements.
