Learning Download: How to Grow Catnip
Catnip has more benefits than satisfying cats. The perennial herb is a member of the mint family and can attract beneficial insects to the garden while keeping pests away. Catnip is an easy-to-care-for herb that spreads quickly and does best along garden beds or as a border. It can also be grown in containers or in hydroponic systems. In addition to its foliage, catnip grows white and lavender flowers and can reach four feet in height.
Before Planting: Catnip can be planted from seed or transplanted into the herb bed, but if planting from seed there are certain steps to take to ensure germination. Catnip seeds are tough and need to be stratified, which means they need to be slightly damaged before they will sprout. To stratify a catnip seed, freeze the seeds overnight and then leave the seeds to soak in water for 24 hours.
Planting: After you have stratified the seeds, you can plant them indoors or outdoors. If planting outdoors, plant in rows after the last chance of frost. Catnip seeds can be planted in the spring or in the fall.
Watering: Water every other week unless in a drought, water once every week.
Fertilizer: Catnip grows very quickly and does not require fertilizer. Fertilizing catnip can actually damage the potency of its smell and flavor.
Days to Maturity: Catnip leaves can be plucked at any point during their growing season and flowers should be picked just after they open. (See variety for days to maturity)
Harvesting: Pinch off individual leaves and flower blooms or cut entire stems depending on usage. Collect seeds from the flowers to replant if desired, but the catnip will reseed itself in the same spot and return each year.
Tips: Catnip can become invasive, and to prevent it from reseeding itself, remove the flowers prior to them going to seed.
Our Seed Promise
"Agriculture and seeds" provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants.
The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats. We feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to further assess the potential risks of genetically engineered seeds. Further, we wish to support agricultural progress that leads to healthier soils, to genetically diverse agricultural ecosystems, and ultimately to healthy people and communities.
