The appropriate soil depth for each species should be determined by taking into account the visual quality of the plant, including the growth conditions of the trees and total photosynthesis. The purpose of this study was to investigate the growth characteristics -height, root collar diameter, dry weight- and quality index according to soil depth. Therefore this study proposed suitable plants according to container size (soil depth) when creating a container garden. The result are as follows; Pinus densiflora, Pinus parviflora and Nandina domestica have poor growth and low ornamental value at 15 cm depth. Therefore, theu will be available at a minimum depth of 20c m. Thuja occidentalis grew in 15 cm of soil depth and had a normal visual value, but it was desirable to plant 20 cm of soil depth. Ilex serrata grew at least 20 cm above depth but it was not suitable for container garden because of its low value of ornamental value. Syringa vulgaris had little difference in growth depending on soil depth. Considering the visual quality, it will be possible to plant for container gardening at a soil depth of 20 cm or more. Container gardens are an alternative to forming green spaces in places where planting is difficult in the city. Therefore, appropriate containers and plants should be selected.
