Nepeta cataria grow best in well-draining soil with a pH between 6.0 and 7.0. It thrives in full sun to partial shade and tolerates temperatures between 60°F and 80°F (15°C and 27°C). Water regularly, but avoid overwatering.

For optimal growth, plant Nepeta cataria in the spring or fall when the weather is cooler. Sow seeds 1/8 inch deep and 6-8 inches apart. Water gently and keep the soil consistently moist during the first few weeks after planting. Thin seedlings to 12-18 inches apart.

To harvest catnip, cut off the stems of the plant when the leaves are in full growth, usually around mid-summer. Pinch off individual leaves and stems to encourage new growth. Harvest regularly to promote a bushy shape and prevent flowering. Harvest in the morning for the best quality.

Nepeta cataria is susceptible to pests such as aphids, whiteflies, and spider mites. Regularly inspect the plant for signs of infestation and treat promptly with insecticidal soap or neem oil.
