Catnip Seeds
Catnip can be started indoors about 6-8 weeks prior to your last frost date. Can also be direct-seeded after risk of frost has passed.
Seeds should be cold stratified to improve germination. Place seeds in the freezer for at least 24 hours, followed by soaking for an additional 24 hours prior to seeding.
Press seeds into soil and cover only lightly. Keep moist until germination in ~10-20 days (may be longer with cooler temperatures).
Transplant after your last frost date into a sunny or part sun location, with plants 12-18 inches (30-45 cm) apart.
