How Do You Grow & Harvest Horehound?
Horehound, marrubium vulgare, is a perennial member of the mint family. The herb has been used medicinally for centuries. The plant is hardy and can be grown and harvested by most home gardeners. According to Utah State University horehound has no known pests or diseases and can spread through a garden in an almost weed-like manner. Once harvested, it can be used to make candies, teas or cough drops. Plant horehound seeds in the early spring. Horehound seeds germinate slowly and should be planted about a 1/4 inch below the surface. Sow seeds up to three weeks before the last spring frost. Horehound can also be propagated from plant cuttings. Plants should be spaced about 10 inches apart. Water horehound plants sparingly. Horehound is drought tolerant and overwatering is more of a concern than too little water. Apply an all-purpose fertilizer in the spring of the year. Fertilizer encourages leafy growth, and it is the leaves of the horehound plant that are harvested. Harvest horehound w
