What Is Catnip and Why Do Cats Love It?
Catnip is a perennial herb native to Europe and Asia but now grown worldwide. It’s known for its gray-green leaves, lavender flowers, and a strong, minty scent that drives many cats into a state of euphoria. The active compound responsible for this reaction is called nepetalactone, a natural oil found in the plant’s leaves, stems, and seeds. When cats smell or ingest catnip, nepetalactone binds to receptors in their nasal tissue, triggering a response in the brain’s olfactory bulb. This often results in behaviors like rolling, rubbing, purring, leaping, or even temporary hyperactivity.
Interestingly, not all cats respond to catnip. Sensitivity is hereditary—controlled by a dominant gene—so if your cat doesn’t react, it’s likely they simply didn’t inherit the trait. Kittens under six months old also typically don’t respond, as the sensitivity develops with age. But for the majority of adult cats, catnip is a delightful sensory experience that can reduce stress, encourage play, and even help with training.
How to Grow Catnip: Step-by-Step Guide
Growing catnip is one of the easiest gardening projects you can take on. It’s drought-tolerant, pest-resistant, and grows quickly from seed or cuttings. Here’s how to get started.
Choosing the Right Location
Catnip loves sunlight. For outdoor planting, choose a spot that gets at least 6 hours of direct sun per day. It can tolerate partial shade, but full sun produces the strongest aroma and most potent leaves. If you’re growing indoors, place your pot near a south- or west-facing window. Alternatively, use a grow light to ensure your plant gets enough light, especially during winter months.
Soil and Planting Tips
Catnip prefers well-drained soil with a neutral to slightly alkaline pH (around 6.1 to 7.8). It doesn’t need rich soil—in fact, too much fertilizer can reduce the concentration of nepetalactone. If planting in a garden, loosen the soil and mix in some compost for drainage. For containers, use a high-quality potting mix with perlite or sand to improve airflow.
You can start catnip from seeds, seedlings, or cuttings. Seeds can be sown directly outdoors after the last frost or started indoors 6–8 weeks earlier. Lightly cover the seeds—they need darkness to germinate—and keep the soil moist until sprouts appear, usually within 7–14 days.
Watering and Maintenance
Once established, catnip is quite drought-tolerant. Water it when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Container plants may need watering every 2–3 days in hot weather, while garden plants can often go a week or more between drinks.
Pruning is key to keeping your catnip bushy and productive. Pinch back the tips of young plants to encourage branching, and trim back flowering stems after blooming to prevent the plant from going to seed too quickly. This also helps maintain strong scent and flavor.
Indoor vs. Outdoor Catnip Growing
One of the great things about catnip is its versatility. You can grow it just as successfully in a pot on your kitchen windowsill as in a garden bed.
Growing Catnip Indoors
Indoor catnip is perfect for apartment dwellers or those with limited outdoor space. Choose a pot that’s at least 8–10 inches in diameter with drainage holes. Use a lightweight potting mix and place the container where it gets plenty of light. Rotate the pot weekly to ensure even growth.
Be mindful of your cat’s access—some felines will nibble on the plant relentlessly, which can stunt growth. If your cat is overly enthusiastic, consider placing the pot on a high shelf or using a hanging basket out of reach. Alternatively, grow a separate “cat-only” plant they can enjoy freely.
Growing Catnip Outdoors
Outdoor catnip benefits from natural sunlight and airflow, which can enhance its essential oil content. It’s also a magnet for pollinators. Bees, butterflies, and other beneficial insects love catnip flowers, making it a great addition to a wildlife-friendly garden.
However, catnip can spread aggressively through self-seeding. To prevent it from taking over your garden, deadhead spent flowers regularly or grow it in a contained bed or large pot sunk into the ground. This keeps the roots from spreading while still allowing your cat to enjoy the plant.
Harvesting and Storing Catnip
The best time to harvest catnip is just before the flowers fully open, when the concentration of nepetalactone is at its peak. Look for stems with healthy, fragrant leaves and buds forming.
How to Harvest
Use clean scissors or pruning shears to cut stems about 4–6 inches above the base. This encourages new growth and prevents the plant from becoming woody. Harvest in the morning after the dew has dried but before the heat of the day, as this is when the oils are most potent.
Drying and Storing
To dry catnip, bundle the stems and hang them upside down in a warm, dry, dark place with good airflow—like a pantry or closet. Alternatively, spread the leaves on a mesh screen or paper towel. Avoid direct sunlight, which can degrade the oils.
Once the leaves are crisp and crumble easily (usually in 1–2 weeks), strip them from the stems and store in an airtight container. Label the jar with the date—dried catnip retains its potency for about 6–12 months. Keep it in a cool, dark place to preserve freshness.
Using Your Homegrown Catnip
There are countless ways to use your harvest. Rub fresh leaves on scratching posts to entice your cat to use them. Stuff dried catnip into DIY toys, like socks or fabric mice. You can even sprinkle a pinch on your cat’s bed or favorite blanket for a calming effect. Some pet owners also make catnip sprays by steeping dried leaves in hot water, then cooling and spraying the liquid on toys or furniture.
Benefits of Growing Your Own Catnip
Beyond the joy of seeing your cat’s delight, growing your own catnip offers several practical and emotional benefits.
First, it’s cost-effective. A single plant can produce enough catnip for months, even years, with proper care. Compare that to buying small packets at the pet store, and the savings add up quickly.
Second, you control the quality. Store-bought catnip is often dried and stored for long periods, which can reduce its potency. Homegrown catnip, especially when harvested at peak freshness, is far more aromatic and effective.
Third, it’s eco-friendly. Growing your own reduces packaging waste and the carbon footprint associated with shipping commercial products. Plus, you avoid pesticides and additives that may be present in some commercial blends.
Finally, it’s a rewarding hobby. Tending to a plant that brings happiness to your pet creates a special bond—not just between you and your cat, but between you and nature.
Common Problems and How to Solve Them
While catnip is generally low-maintenance, a few issues can arise.
Pests and Diseases
Catnip is naturally resistant to most pests, but aphids, spider mites, or whiteflies may occasionally appear, especially indoors. A strong spray of water or insecticidal soap usually does the trick. Powdery mildew can occur in humid conditions—improve airflow and avoid wetting the leaves when watering.
Overgrown or Leggy Plants
If your catnip becomes tall and sparse, it’s likely not getting enough light or needs pruning. Trim back the stems by one-third to encourage bushier growth. Move indoor plants to a sunnier spot or add a grow light.
Cat Damage
Some cats love catnip so much they’ll chew or dig up the plant. If this happens, consider growing a sacrificial plant just for your cat or using a protective cage around the base. Alternatively, harvest frequently to keep the plant compact and less tempting.
Final Thoughts: A Gift for You and Your Cat
Growing a catnip plant your cats will love is more than just a gardening project—it’s an act of love. It’s about creating moments of joy, encouraging natural behaviors, and giving your feline companion a safe, stimulating environment. Whether you’re a seasoned green thumb or a complete beginner, catnip is a forgiving and rewarding plant to grow.
With just a little sunlight, water, and care, you’ll have a thriving herb that delights your cat and enhances your home. So grab a pot, plant some seeds, and get ready to watch your kitty leap, roll, and purr with pure happiness. Your cat will thank you—probably with a head bump and a contented nap in the sun.
