How to Grow Catnip?

Home and Garden

Growing catnip, also known as catmint, is a delightful and rewarding experience for both cats and their owners. Catnip is a member of the mint family, and its leaves and stems contain a chemical compound called nepetalactone, which can have a stimulating effect on cats. In this comprehensive guide, we will explore the step-by-step process of growing catnip, from selecting the right variety to harvesting and preserving the plant. So let’s get started!

1. Choosing the Right Catnip Variety

Before you start growing catnip, it’s important to choose the right variety that suits your needs. Here are some popular catnip varieties you can consider:

  • Nepeta cataria: This is the most common variety of catnip, known for its strong aroma and attractive white flowers.
  • Nepeta faassenii: Also known as dwarf catnip, this variety is smaller in size and has lavender-blue flowers.
  • Nepeta mussinii: This type of catnip is ideal for rock gardens or borders, with its compact form and bright blue flowers.

Choose a variety that suits your space, climate, and aesthetic preferences.

2. Preparing the Soil

Once you have chosen the catnip variety, it’s time to prepare the soil for planting. Catnip thrives in well-draining soil with a pH level between 6.1 and 7.8. Follow these steps to prepare the soil:

  1. Choose a sunny location: Catnip requires at least six hours of direct sunlight per day, so select a spot in your garden that receives ample sunlight.
  2. Clear the area: Remove any weeds or debris from the chosen location to give your catnip a clean start.
  3. Loosen the soil: Use a garden fork or tiller to loosen the soil to a depth of 12-15 inches. This will improve drainage and allow the roots to grow freely.
  4. Amend the soil: If your soil is heavy clay or sandy, consider adding organic matter like compost or well-rotted manure to improve its texture and fertility.
  5. Level the soil: Rake the soil surface to create a smooth and even bed for planting.

With the soil prepared, you are now ready to plant your catnip seeds or seedlings.

3. Planting Catnip Seeds or Seedlings

Catnip can be grown from seeds or purchased as young seedlings from a nursery. Follow these steps to plant catnip:

  1. Direct sowing: If you choose to sow catnip seeds directly in the garden, do so after the last frost date in your area. Scatter the seeds on the soil surface and lightly press them into the soil.
  2. Transplanting seedlings: If you opt for seedlings, plant them in pre-dug holes with a spacing of 12-18 inches between each plant. Gently firm the soil around the seedlings to secure them in place.
  3. Water thoroughly: After planting, water the soil thoroughly to settle it around the seeds or seedlings. Avoid overwatering, as catnip prefers slightly dry conditions.

Now that your catnip is planted, proper care and maintenance are crucial for its growth and development.

4. Providing Adequate Care and Maintenance

Like any plant, catnip requires regular care and maintenance to thrive. Here are some important aspects to consider:

4.1 Watering

While catnip is relatively drought-tolerant, it still requires regular watering, especially during dry periods. Water the plants deeply once a week, allowing the soil to dry slightly between waterings. Avoid overhead watering, as wet foliage can lead to fungal diseases.

4.2 Mulching

Applying a layer of organic mulch around your catnip plants can help conserve moisture, suppress weeds, and regulate soil temperature. Use materials like straw, wood chips, or compost, and spread a 2-3 inch layer around the base of the plants, keeping it away from the stems.

4.3 Fertilizing

Although catnip is not a heavy feeder, you can give your plants a boost by applying a balanced organic fertilizer once in early spring. Follow the instructions on the fertilizer package to determine the appropriate amount and method of application.

4.4 Pruning

To promote bushier growth and prevent catnip from becoming leggy, it’s important to prune the plants regularly. Pinch off the top one-third of the stems every few weeks, starting from when the plant reaches a height of 6-8 inches. This will encourage branching and result in a fuller plant.

4.5 Controlling Pests and Diseases

Catnip is generally resistant to pests and diseases. However, occasional problems like aphids, spider mites, or powdery mildew may occur. Monitor your plants regularly and take appropriate measures, such as using organic insecticidal soap or neem oil for pest control and ensuring good air circulation to prevent fungal diseases.

5. Harvesting and Preserving Catnip

Once your catnip plants reach the flowering stage, it’s time to harvest the leaves and flowers for your feline friend’s enjoyment. Follow these steps to harvest and preserve catnip:

  1. Choose the right time: Harvest catnip in the morning, after the dew has dried but before the sun is too hot. This is when the volatile oils responsible for the plant’s aroma and effects are at their peak.
  2. Harvesting leaves: Use sharp scissors or pruning shears to cut the stems just above a set of leaves. This will encourage new growth and ensure a continuous supply of fresh leaves.
  3. Harvesting flowers: Cut the flower clusters just as they start to open. Flowers can be dried and used for making catnip sachets or toys.
  4. Drying: Tie small bunches of catnip stems together and hang them upside down in a cool, well-ventilated area. Once fully dry, remove the leaves from the stems and store them in an airtight container.

Catnip leaves can be used fresh or dried to stimulate your cat’s senses. Avoid giving your cat excessive amounts of catnip, as it may lead to overstimulation.

FAQs (Frequently Asked Questions)

FAQ 1: Can I grow catnip indoors?

Yes, catnip can be successfully grown indoors. Select a sunny window or use grow lights to provide sufficient light. Follow the same planting and care instructions mentioned earlier, ensuring proper drainage and adequate airflow.

FAQ 2: How long does it take for catnip to grow?

Catnip typically takes 7-10 days to germinate from seeds, and seedlings can be transplanted outdoors after 2-3 weeks. With proper care, catnip plants reach maturity and start flowering within 8-12 weeks.

FAQ 3: Can I grow catnip from cuttings?

Yes, catnip can be propagated from stem cuttings. Take 4-6 inch cuttings from healthy, established plants and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and provide indirect light until roots develop.

FAQ 4: How often should I replace catnip plants?

Catnip plants are perennial and can last for several years with proper care. However, over time, the plants may lose their vigor and potency. It’s a good idea to replace catnip plants every 2-3 years to ensure a fresh and potent supply for your cat.

FAQ 5: Can catnip be harmful to cats?

Catnip is generally considered safe for cats and is non-addictive. However, some cats may exhibit aggressive behavior or excessive excitement when exposed to catnip. If you notice any unusual reactions, it’s best to limit your cat’s exposure to catnip.

FAQ 6: Can humans use catnip?

Catnip is primarily grown for cats, but it has various uses for humans as well. It can be brewed into a tea, which is known for its calming properties. Additionally, catnip leaves can be used in salads, herbal infusions, or as a natural insect repellent.


Growing catnip is a wonderful way to provide entertainment and stimulation for your feline companion. By selecting the right variety, preparing the soil, and providing proper care and maintenance, you can successfully grow catnip in your garden or indoors. Harvesting and preserving the leaves and flowers will ensure a continuous supply of catnip for your cat’s enjoyment. So why not embark on this rewarding journey and watch your cat go wild for the magical herb!
