Organic Catnip Seeds

Catnip seeds are easy to grow! This perennial herb gives your furry cat babies something to enjoy from the garden. Catnip is a favorite of our beloved cats, NaPali & Moana. We like to dry catnip and put it in their toys; they go crazy for it!

And did you know that humans like catnip, too? Grow catnip seeds for your furry cat babies, for harvesting leaves to make mint-like tea, or simply for enjoyment in your garden — bees love the white flowers!

Please note that catnip seeds are small and require light to germinate. Sow very close to the soil’s surface, covering only with the slightest dusting of finely sifted soil.

Planting by Zones

Zones 9-10

• Catnip seeds can be grown in both the cool and warm seasons of Zones 9 and 10.

Zones 2-8

• Sow seeds indoors 6-8 weeks before the last frost. Plants go dormant in cold winters; apply mulch if temperatures go below 0°F.

Planting Catnip Seeds

• Catnip is best transplanted out into the garden. Sprinkle seeds on the top of moist high-quality seed starting soil and gently press them into the soil. Do not cover with soil; catnip seeds require light for germination. Seeds must remain moist to germinate evenly and quickly.
• Plants can be transplanted into individual containers once the seedlings have four true leaves.
• Be sure to fertilize regularly with an organic liquid fertilizer once the seedlings have germinated and have their first set of true leaves.
• Plant your transplants out in the garden when they are 4-5″ tall, spacing them at least 12″ apart. 
• If you are direct sowing the seeds (not recommended), make sure you sow them in debris-free, well-worked soil that has been deeply watered. Follow the same directions as above.

Growing Catnip

• Keep your plants weed-free by pulling any weeds that may compete with your crop.

Growing Catnip in Containers

• This herb is an excellent container crop. As with other members of the mint family, it can quickly take over a garden area. Planting in containers helps contain the spread.
• Make sure your container is at least 10″ deep. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture.
• During hot, dry months, move your container into an area of part shade.

Harvesting Catnip

• The key to a happy herb is to use it! Harvest individual leaves or cut entire stems about 2″ above the base of the plant. For best flavor, harvest stems just before the plants form flowers. You can cut back established plants several times during the growing season.

Southern California Pro-tips

• In areas of Zones 9 and 10, lemon balm is an easy crop that will give you delicious foliage.
• Cut back before flowering (harvest) for repeated foliage.
• Mulch heavily around your plants to ensure the soil does not dry out or heat up too much. Compost added to the soil at planting time will help retain soil moisture during hot, dry weather.
• Does best in full sun. During our hottest months of August, September, and October, plants can suffer from the heat. Using shade cloth can help protect the plants from extreme heat.

Companion Flowers/Crops

• Planting catnip seeds will help attract bees and other beneficial insects once it goes to flower. 
• Grow in your garden along with other herbs having medicinal properties. We suggest holy basil, calendula, hyssop anise, and yarrow. Shop all medicinal herb seeds here!
