Abstract
Vegetable gardening, which can be enjoyed all the way through to harvesting, has become increasingly popular
in urban areas in recent years. However, in urban areas where there is no farmland nearby, it is necessary to use
planters of a certain size and depth to secure the soil necessary for vegetable cultivation. For this reason, we have
designed and produced original planters made of cedar wood and have used them for vegetable cultivation. However,
this planter design had several drawbacks, including the need to communicate the specifications to a lumber store
and have the parts made each time they were produced, the complicated structure requiring many screws for
assembly, and the tendency for the solid cedar wood to decay and deteriorate due to soil moisture in the planter. In
order to solve these problems, a new prototype planter using plywood with a simple structure was developed, and its
ease of assembly and durability against soil moisture were verified. As a result, we confirmed that the planter greatly
reduces assembly labor, and its durability against moisture is the same as that of conventional planters.
