Cultivation

It grows in moist areas in woodland on low hills or mountains at an elevation of 200–1600 m. The plant grows best in light and medium-well drained soils with plenty of moisture with a neutral to acidic pH and in full sun to semi-shade.[3]

The leaves and roots of the plant are edible raw or cooked. The plant has many medical uses and is used to treat lung abscesses, milk-flow obstruction and inflamed boils, among many others.

Slugs and snails eat young shoots.

The plant is propagated by seed that are surface-sown onto ericaceous compost. Division is also possible, although great care must be taken as the plant is intolerant of root disturbance.

The plant is grown commercially in Hoengseong County, Gangwon Province, South Korea, where it is an important part of the local agriculture. However, many South Koreans grow a small amount in personal gardens.

Uses

Korea

The roots of deodeok (더덕), are used in Korean cuisine. They are eaten both fresh and cooked. Grilled marinated deodeok, called deodeok-gui, is often served as a vegetarian main dish. Deodeok can be pan-fried as jeon, pickled as kimchi, or used in fusion dishes such as salads.
