How to Grow Asafetida Spice

Asafoetida is widely used in India as a medicinal herb and as a spice in cooking. The spice is derived from the gum collected from the roots of a giant fennel plant (Ferula assa-foetida L.). The plant frequently is referred to as the devil's dung because of its pungent odor. Asafoetida is hardy to United States Department of Agriculture plant hardiness zone 8 and, in general, is not a common herb to grow in the home garden. Start asafoetida from seed indoors in the fall and transplant the young plants outdoors in the spring.

Instructions

    • 1

      Plant asafoetida seeds in seed trays using rich, well-draining soil. Plant two or three seeds per compartment and cover with a thin layer of soil. Keep the soil moist and in a sunny location indoors or in a greenhouse.

      Transplant healthy asafoetida seedlings when they are approximately 3 to 6 inches tall into their own 4- to 6-inch planting pot. Plant the seedlings the same depth as before. Continue to keep the soil moist and in a sunny location indoors until spring.

      Transplant the asafoetida seedlings outdoors in the spring when the danger of frost has passed. Plant them about 24 inches apart in a sunny location. Asafoetida tolerates most soil types provided it has good drainage. Allow the soil to dry out before watering the plants again.

      Apply a 2- to 3-inch layer of mulch in the fall before the first frost. Mulch protects the roots, especially during the first winter. When new growth commences in the spring, begin to water it again. It will take at least four years of similar care before the roots can be harvested to make the asafoetida spice.
