• If you're growing catnip from seeds, you'll first need to prepare the seeds. Catnip seeds need to be properly stratified before they can sprout.
  • Place the seeds in the freezer overnight and then place them in a bowl of water for 24 hours.
  • After the 24 hours have elapsed, you may plant the seeds outdoors or in pots.
  • Thin them to one plant per 20 inches after the sprout.
  • Each plant should be spaced between 18-20 inches apart.
  • Plant in well draining soil and in full sun.
  • Catnip does not need to be fertilized, just as long as it gets watered on a regular basis.
  • Be sure to remove the flowers before they go to seed, otherwise catnip can become invasive in your garden.


  • Catnip doesn't require much care.
  • Be sure that the soil is well draining and the plants receive full sun.
  • If it doesn't rain, water the cat nip plants once a week.


  • You can harvest catnip once it has reached an appropriate height, about 18 inches.
  • Harvest by cutting the stem from the bottom and do so in the mid-mornings.
  • Remember that the more catnip you cut, the more the plant will grow. Eventually, your catnip plant will have a high output and it's also an invasive plant. Keep away from other plants to prevent spreading.
  • Dry out the catnip leaves on a paper towel. Dried leaves make excellent tea or alternatively, you can stuff them in sachets to make a catnip toy for your fur baby.

So now that you know how to grow catnip, it's time to roll up your sleeves and get to planting!
