Growing directions
Sow seeds 1/4 in deep in warm starting mix and keep consistently warm at 70–80°F until germination; transplant after last frost into sandy or loamy, well-drained soil. Ashwagandha thrives in hot, dry conditions similar to its native Indian range — avoid overwatering and boggy soil. The fleshy taproot is the primary medicinal part and is harvested after the plant's first autumn, when the small lantern-like berries begin to turn red. Wash, slice, and dry the roots for use in adaptogenic powders and decoctions; yields improve substantially if plants are grown through a full growing season.
