Not everyone has the benefit of a plot of land where they can create a garden. In fact, almost 25% of city homeowners lack the yard space needed to cultivate and grow a decent sized garden (according to Seattle Lawn and Garden) meaning more and more people interested in harvesting flowers, vegetables, and herbs are turning to containers. The options provided by containers are plentiful, from bringing your tomato plants inside during the winter to being able to rearrange them if you are doing construction or playing a game outside. But, getting crops to grow effectively in containers is another matter entirely.
