Growing Tips

Cold-stratify seeds for 4-6 weeks before spring sowing to break dormancy and improve germination rates significantly.

Harvest roots in the fall of the second or third year for maximum concentration of active compounds (alkylamides, polysaccharides).

Allow some plants to flower and set seed for field re-establishment; Echinacea also has ornamental appeal that can add value.
