Understanding Catnip: More Than Just a Kitty Treat

Before we delve into the art of growing catnip indoors, it’s important to understand what catnip is. Catnip, scientifically known as Nepeta cataria, is a member of the mint family (Lamiaceae). While it’s famous for its effects on cats, catnip is a versatile herb with several uses. It can be used to make calming tea and adds a unique flavor to salads and savory dishes. This herb is not just for your feline friends; it can benefit you too!

Catnip is a hardy perennial plant that thrives in USDA hardiness zones 3-9. It’s also well-suited for container gardening. The growing season for catnip is during the spring and summer, with the plant going dormant in the winter. This herb produces inconspicuous white flowers and boasts rapid growth under the right conditions.

Why Do Cats Go Crazy For Catnip?

Clematis-4 How to Grow Catnip Indoors: A Guide for Cat Lovers

One of the most intriguing aspects of catnip is its effect on cats. Cats go wild for catnip because of a compound called nepetalactone found in the plant’s foliage. When cats rub or crush catnip leaves, they release the essential oil, which acts as a potent attractant. This triggers a unique response in cats, commonly known as “catnip fever.”

Inhaling the aroma of catnip makes cats behave erratically, often resulting in bouts of playful energy. However, when cats consume catnip, the reaction is quite the opposite. It tends to mellow them out. Keep in mind that not all cats are affected by catnip; it’s hereditary, and only about 50-60% of cats respond to it.

Clematis-6 How to Grow Catnip Indoors: A Guide for Cat Lovers

Growing catnip indoors is a rewarding endeavor that requires minimal effort. Here’s a comprehensive guide to get you started:

1. Stratify the Catnip Seeds

Catnip seeds grow best if they are stratified before planting. This process involves placing them in the freezer overnight, followed by soaking them in water for 12-24 hours. Stratification helps break down the seed’s protective coating, promoting quicker and more successful germination.

2. Choose the Right Container

Select a container that is at least 8 inches deep and 8 inches wide with drainage holes. Avoid breakable containers, as cats may get curious and knock them over.

3. Prepare the Soil

Moisten potting soil until it’s damp but not soggy. Fill the container with the soil, gently pressing it down.

4. Plant the Stratified Seeds

Sprinkle the stratified catnip seeds on top of the soil and lightly cover them. Place the container in a sunny location with ample light.

5. Maintain Moisture

Mist the soil daily to keep it moist but not waterlogged. The seeds will sprout within 8-15 days.

6. Adjust Watering as They Grow

Reduce watering to every 4-7 days once the seedlings reach 1-2 inches in height. Afterward, water every 7-12 days or when the top inch of soil is slightly dry.

7. Harvest Leaves

When the catnip plant reaches 6-8 inches in height, you can start harvesting leaves for your cat. Removing flower buds encourages leaf growth.

8. Prune and Rest

During the winter, reduce watering to allow the plant to rest. Prune the plant when it becomes scraggly or cut it down after it flowers, leaving about 3 inches in the pot. New growth will emerge in a few weeks.

Sharing Catnip With Your Feline Friends

Cats love both fresh and dried catnip. You can pluck leaves directly from the plant and crush them between your fingers to release the enticing aroma. Dried catnip is also a hit among cats. You can use a dehydrator or dry it naturally in the sun. Be prepared for neighborhood cats to visit if you opt for the outdoor drying method. Store dried catnip in an airtight container or the freezer to maintain its potency.

Catnip Plant Care Tips

Growing catnip indoors comes with its own set of challenges, primarily related to light and water. Here are some care tips to ensure your catnip plants thrive:

  • Provide Adequate Light: Catnip plants need at least 6 hours of full sunlight per day. If natural light is insufficient, consider using grow lights, like T5 fluorescent plant grow lights or energy-efficient LED lights.
  • Pinch Off Flowers: When you spot flowers on the plant, remove them. This encourages more foliage growth, which your cats will appreciate.
  • Consistent Watering: Water the plant at least once a week, but check the top layer of soil for dryness before watering. Avoid overwatering, as it can lead to root rot.
  • Pruning: When the plant becomes scraggly or has flowered, prune it. Alternatively, cut the entire plant down after flowering, leaving about 3 inches in the pot. New growth will emerge in a few weeks.

Propagating Catnip Plants

If you want to share the joy of catnip with fellow cat owners or expand your catnip garden, you can easily propagate catnip plants. Here’s how:

  • Take Stem Cuttings: Remove a piece of new growth early in the season using scissors. Lightly bury the cutting in a pot filled with moistened potting soil.
  • Provide Light and Regular Watering: Like growing from seeds, propagated plants need ample light and a regular watering routine. Avoid overwatering.

Once new growth appears, your catnip plants are established and can be integrated into your regular watering schedule.

Humans Can Enjoy Catnip Too

Catnip isn’t just for cats; humans can also benefit from it. You can use catnip in various ways:

  • Tea: Brew catnip leaves in a teapot to make a calming and aromatic tea.
  • Salad: Add fresh catnip leaves to your green salad for a unique and refreshing flavor.
  • Pesto: Incorporate catnip leaves into your pesto recipes to add a delightful twist.
  • Roasted Vegetables: Finely dice catnip leaves and use them in a marinade for roasted vegetables.


Incorporating catnip into your indoor garden is a wonderful way to provide your feline friends with a source of delight and entertainment. It’s an herb that offers benefits for both cats and humans, making it a must-have for every cat owner. Growing catnip indoors is a straightforward process that doesn’t require a green thumb. With the right care, you’ll have a bountiful supply of catnip to keep your cats happy and content.
