Sowing and Growing

Sow catnip seeds just after the last frost of spring outdoors or sow inside. Stratification prior to sowing can help germination. Catnip loves full sun, but in places of extreme heat, plant in an area that receives at least five to 6 hours of direct sunlight. Catnip needs space to branch out, so give plants plenty of room. Pinch off flower buds to encourage more leaf growth and prevent self sowing.


To dry catnip, cut about 4 inches above the base of the plant. This can be done multiple times during the growing season ensuring a good supply. Hang upside down to air dry. If you have a cat, make sure you dry them in a place your cat doesn’t have access to. Cats also love the fresh growing herb. Place a small pot of catnip in the window sill and watch your cat visit it several times a day.
