What is Catnip?
Catnip, also known as catmint, is a perennial herb from the mint family Lamiaceae. The botanical name is Nepeta cataria. Native to Europe and parts of Asia and Africa, catnip is now naturalized across North America.
Catnip contains a chemical compound called nepetalactone that is irresistible to domestic cats and some wild felines When cats inhale the scent of catnip, it triggers a euphoric reaction that causes hyperactive behavior like rolling, pouncing, and playfulness.
In addition to being a cat attractant, catnip has a long history of use in herbal remedies, as a culinary herb, and also in natural insect repellents. The leaves have a pleasant minty, lemon-tinged flavor.
Growing Catnip Indoors
Catnip thrives when grown indoors as a houseplant and is quite easy to cultivate successfully inside. Here are some key considerations for growing catnip indoors:
Light Requirements
Catnip grows best in full sun and needs around 6 hours of direct sunlight daily (or 12-14 hours under grow lights). A bright, south-facing window is ideal. With insufficient light, growth will be stunted and sparse.
Temperature
Ideal temperatures for growing catnip indoors are between 60-70°F. As a cold hardy perennial, catnip can tolerate lower temperatures but growth slows below 50°F. High heat above 80°F can cause floppy, leggy growth.
Watering
Catnip prefers evenly moist soil but not constantly soggy. Water whenever the top inch becomes dry. Drooping leaves often indicate under watering. Ensure the pot has drainage holes and do not allow water to pool in the saucer.
Soil
Use a well-draining potting mix made for herbs and vegetables. Soil pH between 6.0-7.0 is optimal. Mix in sand or perlite if your soil retains too much moisture.
Fertilizer
Feed monthly with a liquid fertilizer for herbs at half strength concentration. Avoid over-fertilizing as this causes excessive leaf growth at the expense of flavor.
Containers
Choose containers at least 4” deep with drainage holes. Shallow pots dry out too quickly. Catnip has a taproot and appreciates deeper pots.
How to Grow Catnip from Seed
Growing catnip from seed indoors is fast and easy. Follow these steps:
-
Fill starter pots or trays with moist potting soil. Level and lightly compact.
-
Sow seeds just below the surface, 1⁄4 inch deep. Space 1-2 inches apart.
-
Cover seeds gently with soil or vermiculite. Water gently to avoid displacing seeds.
-
Place in a warm spot with 65-75°F temperatures. Keep soil moist but not saturated.
-
Germination occurs within 7-14 days. Provide ample sunlight once sprouted.
-
Transplant seedlings once they reach 3-4 inches tall. Pinch back tips to encourage bushiness.
Growing Catnip from a Seedling
You can also grow catnip indoors from a nursery seedling or plant purchased at a garden center. Look for young plants about 3-4 inches tall. Follow these tips:
-
Gently loosen root ball before transplanting into potting mix, being careful not to damage roots.
-
Bury stem up to the first set of leaves. Tamp down soil gently.
-
Water thoroughly after transplanting and let excess drain fully.
-
Allow 1-2 weeks for seedling to adjust before resuming fertilizing.
-
Pinch back the tips of each stem by 1/3 to promote bushy growth.
Caring for Catnip
Once established, catnip requires minimal care. Follow these growing tips:
-
Pinch back leggy stems often to encourage full, bushy growth.
-
Remove flower buds to prolong leaf production. Catnip flowers diminish flavor.
-
Check soil moisture regularly. Water when the top 1-2 inches become dry.
-
Mist leaves occasionally to boost humidity around the catnip.
-
Turn pots frequently so all sides receive equal light exposure.
-
Keep catnip away from drafts from heating/cooling vents.
-
Rotate catnip plants outside in summer to refresh plants.
Harvesting and Using Catnip
-
Snip sprigs of catnip once plant is at least 6 inches tall. Cut back to a leaf node.
-
Harvest in morning after dew dries for highest oil concentration.
-
Cutting often encourages more growth. Leave some stems when harvesting.
-
Hang upside down to dry. Crumble dried leaves to fill cat toys or use in teas.
-
Add fresh leaves to salads, soups, pesto or other dishes. Imparts a light minty flavor.
-
Make catnip tea from dried leaves to aid relaxation and sleep. Also used for upset stomach.
Troubleshooting Common Catnip Problems
Yellow leaves – Overwatering or insufficient fertilizer
Leggy growth – Needs more sun exposure
Wilting – Under watering or pot-bound roots
Slow growth – Low temperatures or insufficient sunlight
Flowering – Remove buds to prolong leaf production
White powdery coating – Powdery mildew fungus, increase air circulation
Chewed leaves – Cats find it irresistible! Keep indoor plants out of reach.

Can you grow catnip indoors?
Growing catnip indoors is a very easy task to achieve. Growing catnip is safe and non- toxic to humans and pets. The plant is an aggressive grower, though, so it is best to give the catnip plant a lot of space to grow, especially if you plan to develop it for the long haul.
Can catnip grow in containers?
Catnip also grows well in containers. In fact, a planting site with some kind of boundary, such as a pot, raised garden bed, or stone wall will help to contain catnip’s spread. You can also grow an indoor catnip plant. All you need is a sunny sill with direct light. Space catnip plants 18 to 24 inches apart in the garden.
Where do catnip plants grow best?
Indoor catnip plants grow best in a sunny window. Catnip grows well in a variety of soils, including rocky and dry soil. However, they thrive in loamy and sandy soil. Whatever you choose, make sure the soil has good drainage. These plants do well with little water.
Can catnip grow in hot weather?
Don’t overwater or allow the plant to sit in soggy soil. The preferred growing temperature for catnip plants is 55°F to 85°F. Catnip prefers a moderate climate—too hot or too humid, and it begins to suffer. If you live in a high-humidity area and want to grow catnip, good air circulation is important to reduce the chances of fungal growth.
