I enjoy container garden for so many reasons. I have several of various sizes sitting around the garden waiting to transfer inside when necessary. It is the opportunity to keep the fresh produce growing year round. Several years ago someone decided it would be unique to create an upside down container and called it Topsy Turvy. It's a useful idea for various reasons. You can hang the planter from the patio and watch you crops grow right from the back door. If you intend on moving the harvest indoors when the weather turns cool they are easy to transport. They require no weeding and take up little space. Gravitating downward promotes quicker growth and often a larger harvest.
