Catnip Plant Care

Catnip (Nepeta cataria) belongs to the Lamiaceae family within the Nepeta genus. Catnip is native to southern and eastern Europe, northern parts of the Middle East, and Central Asia. Catnip is also known as Catmint, Catswort, Catrup.

Catnip displays a low mounding perennial growth habit, reaching up to 1.5 inches tall with a spread of approximately 2 inches. Catnip produces small tubular flowers in shades of blue, purple, or white.

Leaf size: approximately 2 inches.

Nepeta cataria requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Catnip thrives in full sun to part shade light conditions. The optimal light range is 200–1000 lux. Avoid placing Catnip in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Nepeta cataria grows best at temperatures between 50°F and 80°F. Catnip prefers humidity levels of 40–60%.

Well-draining sandy loam with added perlite for improved drainage. Good drainage is essential for Catnip to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Catnip can be propagated through seeds, division of clumps, stem cuttings.

Catnip is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Catnip grows outdoors in USDA Zone 3 – 9. Native to southern and eastern Europe, northern parts of the Middle East, and Central Asia, Catnip is adapted to warm climates. In cooler regions, grow Catnip as a houseplant or bring it indoors before the first frost.
