Direct sow burdock seed outdoors in spring. Sow seeds 1" deep and 3-6" apart. Seeds will sprout in 6-12 days. Mature plants should be 6-12" apart.


Harvest burdock roots in the fall of its first year or the following spring.

Seed Saving

Burdock is a biennial, meaning it flowers, sets seed and dies during its second year of growth. Allow plants to overwinter in your garden and purple flowers will appear the following summer. Seeds mature in fall. Collect seeds when flowers have dried and turned brown. Store seeds in a cool dry place. Seeds will remain viable for 2 years.
