In this study, we aimed to select the optimum media for pottery pot plant growth of Ilex cornuta Lindl., Ardisia pusilla “Variegata,” Dendrobium moniliforme Sw., and Crassula portulacea, which were plant commercial medium, a hydro ball, kanumatsuchi, decomposed granite, and sphagnum m oss. T he s urvival rate o f Ilex cornuta in the hydro ball, sphagnum moss, and kanumatsuchi was 100%. The increass inplant height growth and in the number of leaves were 26.7% and 26.8% in sphagnum moss and 20.6% and 23.7% in kanumatsuchi, respectively; the increase was low when grown in decomposed granite (6.7% and 14.1%, respectively). The number of leaves per plant height was 10.0 in kanumatsuchi and 8.0 in decomposed granite. T /R r atio w hen grown in k anumatsuchi and sphagnum moss was balanced at 1.0 or 1.1. The survival rate of Ardisiapusilla “Variegata” in all media was 100%. The increas plant height growth and in the number of leaves was 27.3% and 60.8% in kanumatsuchi and 30.7% and 50.5% in sphagnum moss, respectively, which was higher than that in the other potting media. The number of leaves per plant height was 2.5 in kanumatsuchi and 2.2 in sphagnum moss, which was higher than that in the other media. The survival rate of Dendrobiummoniliforme Sw. was also 100% in all media. T he i ncreas p lant h eight growth a nd n umber of leaves was 17.6% and 12.6% in a commercial medi 16.0% and 24.6% in ahydro ball, respectively, the increase was low when grown in decomposed granite (8.5% and 7.2%, respectively). The number of leaves per plant height was 3.4 in ahydro ball and 1.9 in decomposed granite. T/R ratio was 2.5 in ahydro ball and 2.0 in kanumatsuchi. The survival rate of Crassula portulacea was also 100% in all media. The increas plant height growth rate and in the number of leaves was 62.6% and 50.9% in a commercial medium and 69.7% and 53.1% in kanumatsuchi, respectively, which was higher than that in the other media. However, the increase was low when grown in hydro ball (28.0% and 27.7%, respectively). The number of leaves per plant height was all media, except for the hydro ball. The T/R ratios of sphagnum moss and the commercial medium was 10.8 and 10.7, in which top growth was higher than root growth. Therefore, for commercial export purpose, it is preferable to plant Ilex cornuta Lindl., Ardisiapusilla “Variegata,” and Crassula portulacea in sphagnum moss and kanumatsuchi and Dendrobium moniliforme Sw. in hydro ball.
