Growing Licorice Root

Licorice is a deep-rooted perennial herb that prefers warmth, sun, and a long growing season.

Prefers full sun and loose, deep, well-drained soil
Benefits from regular moisture during establishment but dislikes waterlogged conditions
Generally suited to USDA zones 7-10, with best growth in warmer parts of the United States
Can be grown in sunny garden beds where roots have room to develop over time

Individuals with high blood pressure, kidney disease, or heart conditions should use caution and seek professional guidance.
Licorice root may interact with certain blood pressure medications, diuretics, corticosteroids, and other prescription drugs.
Pregnant individuals are generally advised to avoid high intake of licorice root.
Products labeled deglycyrrhizinated licorice are different from whole licorice root and should not be assumed to have the same safety profile.
