NOVELTY - A single tiered planter casing comprises removable and interchangeable shelves or soil retainers (A) of different designs that allow the planter to be used in different ways.    USE - As single tiered planter casing for growing potatoes and as container for producing compost (claimed).    ADVANTAGE - The basic or standard removable and interchangeable soil retainers create the growing shelves of a tiered planter and can be used individually to completely block off or cover the growing area of a shelf that is not being used on the planter. The basic or standard removable and interchangeable soil retainer gives easy access for emptying, refilling and harvesting when using a tiered planter; allows the distance between the used growing shelves of a tiered planter to be regulated and the ability to give the required space needed for growing large leaf plants without directly hindering the growth of any plants in the tiers above or below. The basic or standard removable and interchangeable soil retainer covers any growing shelf of a tiered planter that is not being used and hinders any weeds from growing in that growing shelf. The basic or standard removable and interchangeable soil retainer allows a tiered planter to be transformed into a large container which is then be used for growing potatoes. The basic or standard removable and interchangeable soil retainer blocks off or covers all of the growing shelves of a tiered planter and transforms a tiered planter into an easily accessible closed in container for producing compost. The modified removable and interchangeable soil retainers hinder the germination of weeds on any of the growing shelves where the soil retainers are used. The container makes it possible to grow plants (when the container is filled with soil or earth), with differing soil depth needs such as salads or potatoes. The retainers have at least one longitudinal slot to allow rows of plants to grow through thereby minimizing weed growth. The shelves or soil retainers of different designs allow a single tiered planter casing to be used in different ways. By using the soil retainers in different ways it is possible to change the layout of a tiered planter and give the user the ability to grow different kinds of vegetables and to be able to remove the soil retainers gives easy access for harvesting, emptying and refilling. When using the different soil retainers designs in different ways the tiered planter can be used more efficiently in different environments.
