This study was carried out to investigate proper planting density and depth of tissue-cultured oriental lily bulblets for bulb production. Planting densities of bulblets were 200, 400, 600, 800, 1,000 bulblets/ $m^2$, and planting depths were 1, 3, 6, 9, 12 cm. Proper planting density of tissue-cultured 'Siberia' bulblets was 400 bulblets/ $m^2$ with 87.3% of survival rate, 6.4 cm of bulb circumference, and 8.3 g of bulb weight. For 'Sorbonne', it was thought to be 400 bulbs/ $m^2$ with 88.8% of survival rate, 5.0 cm of bulb circumference, and 7.1 g of bulb weight. Proper planting depth of tissue-cultured 'Siberia' bulbs was 3 cm with 77.8% of survival rate, 5.9 cm of bulb circumference, and 7.9 g of bulb weight. For 'Sorbonne' bulbs, it was 3 cm with 87.1% of survival rate, 5.1 cm of bulb circumference, and 6.5 g of bulb weight.
